Description

Elastic coupling

The present invention relates to an elastic coupling. Such couplings can be used to connect a driven element or unit to an driven element or unit. Frequently, such elastic couplings create a connection between two shaft sections to be connected. The present invention further relates to a thread-reinforced joint device and a thread-reinforced coupling element.

Elastic couplings are known from the prior art and are disclosed, for example, in document DE 196 39 304 A1. This document discloses an elastic articulated coupling with an intermediate ring arranged between two coupling flanges. The intermediate ring has individual metal elements distributed around the circumference and vulcanized into rubber blocks, which alternate with the

Coupling flanges are screwed. The metal elements of the intermediate ring consist of wedges evenly distributed in the circumferential direction. The wedges extend in the radial direction over the entire ring width. Vulcanized rubber blocks between the wedges are under pressure in the circumferential direction under pressure.

It is an object of the present invention to provide an elastic coupling of the type described at the outset which makes optimum use of the installation space available in the radial direction, requires little installation space in the axial direction and can accommodate large flexion angles.

This object is achieved with an elastic coupling with the features of claim 1.

Further embodiments of the invention are specified in the dependent claims.

The elastic coupling for connecting a driven member to a driven member includes a first flange connectable to the driven member, a second flange connectable to the driven member, a plurality of elastic members, each elastic member being connected to the first flange and / or second flange is connected, and at least one support device which is connected to at least some of the elastic elements and supports the elastic elements in the radial direction.

The at least one support device is connected to at least some of the elastic elements and can hold or fix these elastic elements in a predetermined radial position. Since the elastic elements connected to the at least one support device are held in a predetermined radial position via the at least one support device, the

The available radial installation space can be optimally used. In particular, the elastic elements can be held in a radially outer position with the at least one support device, so that the arrangement of the elastic elements, viewed in the axial direction, can take the form of a polygon. In this way, an improved use of an available radial installation space can be achieved. Compared to an elastic coupling without a support device known from the prior art, the number of "corners" of the polygon formed by the arrangement of the elastic elements with the support device can be increased, as a result of which an improved use of installation space is achieved compared to the prior art. The support device can act as an “intermediate piece” between the first flange and the second flange. By arranging the support device and its effect as an “intermediate piece” between the first flange and the second flange, the deflection angle to be compensated for with the elastic coupling can be greatly increased. The support device means that the coupling requires little installation space in the axial direction at least one support device also the torsional stiffness and the axial stiffness of the coupling. The support device can thus be used to provide a coupling which is torsionally and axially relatively compliant or "soft". The at least one support device can be mounted on the fly. There is no direct connection between the at least one support device and the first flange and / or the second flange. The at least one support device can be designed such that it does not contact the first flange and / or the second flange. The first flange and / or the second

Flanges can be designed in such a way that there is no contact with the at least one support device or cannot be made. The support device can be connected to each of the elastic elements. The at least one support device can be designed such that it extends at least in sections radially inside and / or radially outside the elastic elements. The at least one support device can be designed such that it engages the elastic elements radially on the inside in order to hold the elastic elements in their predetermined radial position. The at least one support device can have a plurality of support elements extending in the radial direction. The support elements can be connected to the elastic elements. The support elements can be connected to the support elements via bushings, bolts, screws or other connecting devices. The support elements can be designed in the form of projections or the like. Each support element can be connected to one or more elastic elements. In addition to the support element, the elastic elements can be connected to the first flange and / or the second flange. The first flange can have a plurality of first flange arms. The second flange can have a plurality of second flange arms. For example, each flange can have three or six flange arms. A first flange arm and a second flange arm can be connected at least via at least one elastic element. The connection between a first flange arm and a second flange arm can also be established via a combination of at least one elastic element and at least one support element. In the circumferential direction of the elastic coupling, at least one support element can extend between a first flange arm and a second flange arm. This at least one support element can be connected to one or more elastic elements which connect the first flange arm adjacent to the respective support element and the second flange arm adjacent to the respective support element. The sum of the number of flange arms of the first flange and the second

Flange can correspond to the number of support elements. For example, if each of the flanges has three arms, six support elements extending in the tangential direction are provided.

The at least one support device can be designed such that the radially outer regions of the elastic elements lie on a radius in the region of the flange arms and in the region of the support elements. In other words, the support elements can ensure that the radially outer regions of the elastic elements in the region of the support elements lie on the same radius as the radially outer regions of the elastic elements in the region of the flange arms. The at least one support device can be designed such that the above polygon described for optimized use of installation space and increasing the bending angle,

The support elements can each have at least one connecting device. The at least one connecting device can be designed for connection to at least one of the elastic elements. The at least one

Connecting device can be formed by openings, projections, connecting elements or recesses on the support elements. The at least one connecting device can also be bush-shaped or in the form of a bolt. The support elements can form a receptacle for a section of the elastic elements. The at least one connecting device can be formed by an opening with a thread into which a screw can be screwed. The type of connecting device can depend significantly on the type or shape of the elastic element. The connecting device can extend in the axial direction and / or radial direction.

The at least one support device can be designed such that all of the support elements are connected to one another. The at least one support device can have at least one ring-shaped section which connects the individual support elements to one another. The at least one annular section can extend radially outside around the support elements and connect them to one another. Furthermore, the at least one annular section can extend radially inward along the support elements and connect them to one another. The at least one annular portion can extend radially outward or radially inward of the elastic elements. The annular section may have a predetermined axial extent which is at least greater than or equal to the axial extent of the elastic elements.

The support device can have at least one common plane with the first flange arms and / or the second flange arms, which plane extends perpendicular to the central axis of the coupling. At least the portions of the flange arms of the first flange and the second flange which extend in the radial direction and the support elements of the support device can have a common plane. The elastic elements can also lie in this common plane. However, the elastic elements can also lie in a plane that extends parallel but offset to the common plane of the flange arms and the support device. The axial extent of the support device can overlap at least in sections at least with the axial extent of the radial sections of the first flange arms and / or the second flange arms. Additionally or alternatively, the axial extension of the support device can also overlap with the axial extension of the elastic elements. This overlap is preferably established in the radial direction. The axial extent of the support device can correspond to the axial extent of the radial sections of the flange arms of the first flange and / or the second flange.

An elastic element can connect a first flange arm, a second flange arm and a support element to one another. Additionally or alternatively, an elastic element can connect a first flange arm to the support element and a further elastic element can connect the support element to a second flange arm.

The elastic elements can be clutch wedge assemblies. A clutch wedge assembly can have connecting elements which are connected to one another via an elastic body. The connecting elements can be used to connect the clutch wedge package to a flange arm and / or a support element. The connecting elements can preferably be designed such that they can be connected to the side surfaces of the flange arms and / or the side surfaces of the support elements. The elastic body can have at least one reinforcing element. The elastic body may have a first portion that extends between the connecting element and the reinforcing element and a second portion that extends between the connecting element and the reinforcing element. The connecting elements can be wedge-shaped.

A clutch wedge assembly can have a first connecting element and a second connecting element. The first connecting element can have a projection which is used for connection to the support device. The projection can be received in a receptacle of a support element. The receptacle can be formed in a side surface of a support element. The projection of the connecting element can be clamped in the receptacle. The projection can be formed on a side surface of the first connecting element. The second connecting element of a clutch wedge packet can have a recess.

At least one projection on a first flange arm or a second flange arm can be received in the recess. The head start on the Flange arms extend circumferentially from the side surfaces of the flange arms.

The second connecting element of a clutch wedge packet can have at least one connecting means. The connecting means can be formed on a side surface of the connecting element. The connecting means of the second connecting element can serve to connect the clutch wedge packet to a side face of a first flange arm or a side face of a second flange arm. The connection means of the second connection element can have connection projections or connection recesses. The connecting projections can be designed in the form of a web. The connection recesses can for example be groove-shaped. The connection projections or connection recesses can extend essentially in the radial direction.

The side surfaces of the first and second connecting elements can face away from the elastic body of the clutch wedge assemblies. The side surfaces of the clutch wedge assemblies extend in the axial direction and in the radial direction when the clutch wedge assemblies are mounted on the flange arms and the support elements.

The side surfaces of the first flange arms and the second flange arms can have connecting devices which serve for connection to a second connecting element of a clutch wedge assembly. The side surfaces of the first flange arms and the second flange arms, which extend in the radial and axial directions, can be provided with such connecting devices. The connecting devices on the side surfaces of the flange arms can be designed corresponding to the connecting devices on the connecting elements of the clutch wedge assemblies. The connecting devices on the side surfaces of the flange arms can cooperate with the connecting means of the second connecting elements in order to hold the coupling wedge assemblies on the flange arms.

The connecting devices can secure the clutch wedge assemblies in particular in the axial direction on the flange arms. The connecting means on the second connecting elements can be designed, for example, in the form of connecting projections. In this case, the connecting devices can be groove-shaped on the side surfaces of the flange arms. The groove-shaped connecting devices can extend in the radial direction. The web-shaped connecting means on the second connecting elements of the clutch wedge assemblies can be inserted into the groove-shaped connecting devices. The dome Lung wedge packages are held on the flange arms via the engagement of the projections on the flange arms with the recesses of the second connection element and via the engagement of the connection means of the second connection element and the connection devices on the side surfaces of the flange arms.

The elastic elements can also be thread-reinforced coupling elements.

The thread-reinforced coupling elements can have at least two bushings and at least one thread package which wraps around the two bushings. At least the at least one thread package can be embedded in an elastic body. The at least one thread package can be held on the bushings via one or more collar elements. The collar element or the collar elements can be pushed onto the bushes in the axial direction of the bushings and hold the at least one thread package in its predetermined axial position. The collar elements can be integrally formed with the bushings. The collar elements can extend in the radial direction away from the tubular bushings.

The bushings and the collar elements can also be embedded at least partially or in sections in an elastic body.

The present invention further relates to a thread-reinforced joint device. The thread-reinforced joint device comprises a plurality of sockets, a plurality of yarn packages, wherein each yarn package combines at least two corresponding sockets to each other, and at least one supporting device, wherein the at least some of the yarn packages radially supports at least one supporting means from ^¬.

Depending on their load (tension or pressure), in particular the thread packages could be pulled radially inwards without the support device or pressed radially outwards. The support device can support the thread packages in the radial direction. The support device can in particular prevent the central region of the thread packages between the bushings from being displaced in the direction of the central axis of the thread-reinforced joint device.

The thread-reinforced joint device according to the invention can in particular accommodate medium-sized flexion angles. These bending angles can be between 2 and 4 degrees, for example. By means of the support device, the thread package or packages can be brought into a shape which has several corners. The “number of corners” of the thread-reinforced joint device can be increased by the support device compared to the number of flange arms The articulation device can have more "corners" than the two flanges have flange arms together. The support device can enable the use of longer thread packages which are brought into an "angular" course via the support device. These longer thread packages can be brought or held in this predetermined course due to the support device. By means of the support device, an increased bending angle can be achieved in a space-saving manner, since the effective bending length of the thread packages increases. Furthermore, the thread-reinforced joint device according to the invention can be coupled to shaft sections via two-arm flanges.

As already explained above, the support device can ensure that the thread-reinforced joint device maintains its polygonal structure even during operation. As a result, in particular the medium-sized flexion angles mentioned can be compensated for and the radial installation space can be optimally utilized, since a polygon with as many corners as possible can optimally fill a circular or hollow-cylindrical installation space.

The thread-reinforced joint device can have at least one elastic body. At least one thread package, at least two bushings and at least one deflection element can be at least partially embedded in the at least one elastic body. A plurality of elastic bodies can also be provided, in which thread packages are embedded.

The thread-reinforced joint device can have at least one two-arm flange, i.e. at least one flange with two flange arms. Each flange arm can have at least one connection point. It is also conceivable that each flange arm has two or more connection points.

If the torque capacity of a thread-reinforced joint device with an elastic body is not sufficient, several elastic bodies can also be provided. The elastic bodies can be essentially ring-shaped or disk-shaped. These elastic bodies can be arranged “one inside the other” in the radial direction. For example, one elastic body can be arranged radially inside the other elastic body. The plurality of elastic joint bodies can be arranged coincidently, so that they have a common bending point. The flange arms of the flanges may have a plurality of connection ^¬ points corresponding to the number of elastic bodies. If, for example, two elastic bodies are provided, each flange arm has two Connection points to be able to be connected to the two elastic bodies. These connection points can lie on different radii.

The embodiments of the thread-reinforced joint device with two-arm flanges can have, for example, a second-order rotational irregularity. This can apply regardless of whether the thread-reinforced joint device has one or more elastic bodies with thread packages embedded therein.

If such rotational nonuniformity is not desired in certain applications, the thread-reinforced joint device can have at least one flange with more than two arms. The thread-reinforced joint device can have, for example, a four-arm flange or a six-arm flange. With a four-arm flange, the mentioned second-order rotational irregularity can be compensated for. With the flanges having more than two arms, the rotational nonuniformity can be compensated for in the elastic body or bodies. The flange arms can differ in their radial extension. For example, two of the four arms of the four-arm flanges can be long and two short. The short flange arms can be connected to the radially inner elastic body and the long arms can be connected to the radially outer elastic body. "Short" or "long" here refers to the radial extension of the flange arms. In the case of two flanges, the two flanges can be connected to the at least one elastic body by 90 degrees to one another. A long flange arm of one flange can be connected radially outward of a short flange arm of the other flange to an elastic body. In other words, the connection points of a long flange arm of one flange and a short flange arm of the other flange for connection to an elastic body can lie on a common radial line. The support device can be overhung. In this embodiment, only the overhung support device experiences a rotational nonuniformity.

The thread-reinforced joint device can be composed of several thread-reinforced coupling elements. The thread-reinforced coupling elements can each have at least one thread package which wraps around two bushings and is deflected by a deflection element in the region between the bushings. The thread packages, the bushings and also the deflection elements can be at least partially embedded in an elastic body. Even in the case of several individual thread-reinforced coupling elements, the thread-reinforced joint io

Device have two two-arm flanges which are connected to the coupling elements. The thread-reinforced joint devices can also have a plurality of coupling elements which are arranged in two axially offset planes. The flange arms of the flanges can be provided between the axially offset planes of the coupling elements.

The at least one support device can be designed such that it can deflect the thread packages. The at least one support device can preferably deflect the thread packages in the area between two corresponding bushings. The number of bushings can correspond to the number of support elements.

The support elements can extend in the radial direction. The support elements can extend in the radial direction outwards or inwards. The support elements can be part of a support plate. The support elements can be connected to one another via at least one ring-shaped element or a central base. The annular element can connect the radially outer ends or the radially inner ends of the support elements to one another.

The support device can have a plurality of deflection elements. Each deflecting element can deflect at least one thread package in the area between the bushings assigned to this thread package. The support elements can be connected to at least one deflecting element. At least one thread package can put on the at least one deflection element. The deflection element is from the yarn package ^¬ not or only partially wrapped. The at least one deflection element can be bush-shaped or bolt-shaped.

The thread-reinforced joint device can have a first flange and a second flange. The bushings of the thread-reinforced joint devices can be connected to the first flange and the second flange, so that a torque-transmitting connection can be established between the two flanges via the thread-reinforced joint device. For example, two or more sockets can be assigned to the first flange and two or more sockets to the second flange.

The thread packages and the bushings can be at least partially embedded in at least one elastic body. Furthermore, the deflection elements connected to the support elements can also be embedded in the elastic body. The support device can have two or more support plates. The support plates can be arranged on axial side surfaces of the at least one elastic body. The support plates can have the support elements which are connected to the deflection elements. The support plates can be connected to one another via the deflection elements. Furthermore, screws or similar connecting means can also extend through the deflection elements in order to connect the two support plates to one another.

The thread-reinforced joint device can have a plurality of thread-reinforced coupling elements. The thread-reinforced coupling elements can be arranged in planes offset from one another in the axial direction.

The thread-reinforced joint device can have at least one centering. The at least one centering can have at least one centering element. The at least one centering element can be spherical. The centering can be formed by a first tube extension on a first flange, a second tube extension on a support plate, a first centering element, a second centering element and a centering pin on a second flange. The tube extension of the support plate can be received in the tube extension of the first flange. A centering pin can be provided on the second flange. The first centering element can be provided between the tube extension of the first flange and the tube extension of the support plate. The first centering element can extend between the outer peripheral surface of the tube extension of the first flange and the inner peripheral surface of the tube extension of the support plate. A second centering element can be provided between the centering pin and the tube extension of the support plate. The second centering element can extend between the outer circumferential surface of the centering pin and the inner circumferential surface of the tubular extension of the support plate. The centering elements can be designed in such a way that a flexion movement is supported. The second centering element can be arranged radially within the first centering element. The centering can be coincident, i.e. it has a single point of inflection.

The centering can be composed of two partial centerings. The two parts centering can be offset from one another in the axial direction. The first partial centering can be formed by a tube extension on one of the support plates, a first centering element and a centering pin on the first flange. The second partial centering can consist of a tube attachment on the other support plate, a second centering element and a centering pin on the second th flange are formed. The centering pins on the flanges can be received in the tube extension on the support plate assigned to the respective flange and can be supported on the tube extension via one of the centering elements.

The centering can also be formed by a centering sleeve and a centering pin. The centering sleeve can be arranged on a first flange and the centering pin on a second flange. The centering pin can extend into the centering sleeve for centering. The centering sleeve can have a centering element which can receive the centering pin. The centering element can be connected to the centering sleeve via an elastic layer. The centering element can be spherical or spherical.

The present invention further relates to a thread-reinforced coupling element. The thread-reinforced coupling element comprises at least one thread package, at least two bushings, the at least one thread package wrapping around the at least two bushings, and at least one deflection element, the at least one thread package resting on the at least one deflection element.

The at least one deflecting element can be arranged offset to the at least two sockets. The at least one thread package can rest against the at least one deflection element in the area between the two bushings. The at least one deflection element can be arranged between the two sockets. In particular, the deflection element can be arranged in the circumferential direction between the two bushings. The thread package does not or only barely wraps around the at least one deflection element.

The at least one deflection element can be positioned such that the at least one thread package extends in the area between the bushings with at least one kink or curve. The thread package can form two strands in the area between the bushings. The strands of the thread package are brought closer to one another by the deflecting element, so that at least one of the strands runs kinked or curved. Both strands can also have a kink or a curvature, the strand which lies against the deflecting element being more kinked or curved. The at least one deflecting element can subdivide the thread package into two legs, each of which has a bushing and is angled to one another. The at least one thread package, the at least two bushings and the at least one deflecting element can be at least partially in one elastic body embedded. It is also conceivable for each strand to be assigned a deflecting element which deflects the respective strand.

The thread-reinforced coupling element can have several thread packages. Each thread package can loop exactly two bushings. The thread-reinforced coupling element can have a plurality of deflection elements which are connected to one another via at least one connecting element. At least one deflection element can be assigned to the at least one thread package. A bushing wrapped by a thread package can only be wrapped by this thread package but not by another thread package. However, it is also conceivable that two or more thread packages are wrapped around a socket. Each thread package forms a unit with the two bushings. A thread-reinforced coupling element can have several such units. These units can be at least partially embedded in an elastic body.

A thread-reinforced coupling element can have bushings and deflection elements. A thread-reinforced coupling element can have, for example, two, three or more thread packages. In the assembled state of a coupling element on a coupling, the thread packages can be arranged one above the other in the radial direction. Since each thread package can loop around two bushings, some of the bushings can lie on a first straight line and another part on a second straight line. These lines may or may not extend in the radial direction. The deflection elements can be arranged in an area between the bushings. The deflection elements can be connected to one another via connecting elements. The connecting elements can be arranged at the axial ends of the deflecting elements. The deflection elements can be bush-shaped. Bund elements can be arranged on the bushes, which can hold the thread packages on the bushings. The bushings, the collar elements, the deflection elements and the plate-shaped connecting elements can be partially or completely embedded in an elastic body.

A coupling element can have three thread packages, for example. Each of the thread packages can loop around two bushings. Each of the thread packages can form a unit with two bushings which are wrapped around by the thread package. The deflection elements, which can deflect and support the thread packages, can be provided between the bushings. The deflection elements can over

plate-shaped connecting elements can be connected to one another. The connecting elements can extend on the surface of the coupling element. A Deflection element can bring the two strands formed by the thread package between the bushings closer to one another, so that one of the strands assumes a more kinked course than the other strand. Each of the thread packages can thus be curved or kinked between the bushings.

Two deflection elements can be assigned to the at least one thread package. The at least one thread package can form two strands in the area between the bushings. Each strand of a thread package can be deflected in the area between the bushings by its own deflecting element. The strands of the thread packages can no longer abut each other in the region of the deflecting element, but are separated from one another by a deflecting element. The deflection elements can be connected to one another via the plate-shaped connecting elements.

A support device may have an annular portion and support elements that extend radially inward from the annular portion. The support elements can be connected to the deflection elements using connecting elements such as Screws connected. With its support elements, the support device can support a central region of the thread-reinforced coupling elements in which the deflection elements are arranged. The thread-reinforced coupling elements can be screwed to a first flange via the connecting elements. For this purpose, the connecting elements can be guided through the sockets.

Alternatively or additionally, a support device can have an annular section and supporting elements which extend radially outward from the annular section. The annular section can extend radially within the thread-reinforced coupling elements. The support elements which extend radially outward can hold the deflection elements and thus the central region of the thread-reinforced coupling elements in their predetermined radial position. As a result, the unit comprising the support device and the coupling elements maintains its polygonal structure when attached to the flanges and during operation.

Depending on their load (tension or pressure), the thread-reinforced coupling elements can be pulled radially inwards without the support device or pressed radially outwards. The support device can support the coupling elements in the radial direction. This can apply in particular to the area of the deflection elements which can be connected to the support elements. The support In particular, z elements can prevent the central region with the deflection elements of the thread-reinforced coupling elements from shifting between the bushings in the direction of the central axis.

Figure 1 shows a perspective view of an elastic coupling 10 according to a first embodiment. The elastic coupling 10 has a first flange 12, a second flange 14 and a support device 16.

The first flange 12 has a hub-shaped section 18 with an opening 20 which has an internal toothing. Starting from the hub-shaped section 18, the flange arms 22, 24 and 26 of the first flange 12 extend radially outward. The second flange 14 has a central section 28, from which the flange arms 30, 32, 34 extend outward in the radial direction.

The support device 16 has an annular section 36. Starting from the annular section 36, support elements 38 extend radially inward. The support elements 38 are connected to the flange arms 22, 24, 26, 30, 32 and 34 via elastic elements 40. Each of the elastic elements 40 is connected to the support device 16. Each support element 38 is connected to two elastic elements 40. For example, an elastic element 40 connects the flange arm 22 of the first flange 12 to the support element 38. This support element 38 is connected to the flange arm 30 of the second flange 14 via the elastic element 40. The support elements 38 are each arranged between two adjacent flange arms 22, 24, 26, 30, 32 and 34 of the first flange and the second flange.

The elastic elements 40 are in this embodiment in the form of coupling tion wedge packages 40 formed. The clutch wedge assemblies 40 have a first connecting element 42, a second connecting element 44 and an elastic body 46. The connecting elements 42 and 44 are connected to one another via the elastic body 46. The first connecting elements 42 are used to connect the coupling wedge package 40 to a supporting element 38 or to the supporting device 16.

The second connecting elements 44 of the clutch wedge package 40 serve for connection to a flange arm 22, 24, 26, 30, 32 and 34. For this purpose, the second connecting elements 44 have a recess 48 which has a corresponding projection 50 on the flange arms 22, 24, 26, 30, 32 and 34 can accommodate. The clutch wedge assemblies 40 can be in the radial direction on the projection 50 of the respective flange arm 22, 24, 26, 30, via the second connecting elements 44.

Support 32 and 34. In addition to the projection 50, each flange arm 22, 24, 26, 30, 32 and 34 has a further projection 52. The protrusions 50 and 52 extend in the circumferential direction of the elastic coupling 10. The protrusions 50 and 52 are provided on opposite side surfaces of the respective flange arms 22, 24, 26, 30, 32 and 34. These side surfaces have an extension in the radial direction and in the axial direction. According to this embodiment, the radial sections of the flange arms 22, 24, 26 of the first flange 12, the radial sections of the flange arms 30, 32, 34 of the second flange 14, the support elements 38 and the clutch wedge assemblies 40 have a common plane which is perpendicular to the central axis M the clutch 10 runs. The support device 16 is constructed in several parts. The support device 16 comprises two parts 54 and 56. The parts 54 and 56 are connected to one another by screws 58. The first connecting elements 42 of the clutch wedge assemblies 40 are fastened to the supporting elements 38 by connecting the two parts 54 and 56 of the supporting device 16. For this purpose, the first connecting elements 42 have projections (not shown) which can be clamped between the two parts 54 and 56 of the support device 16.

FIG. 2 shows a further perspective view of the coupling 10. FIG. 2 shows the second flange 14 in the foreground, which has the hub-shaped section 28. The hub-shaped section 28 has an opening 60. A groove 62 is formed in the opening 60.

Openings 64 can be seen in the support elements 38, into which the screws 58 for connecting the two parts 54 and 56 of the support device 16 are screwed become. With the parts 58 and 56 of the support device 16, a clamping force is generated via the screws 58 (see FIG. 1), by means of which the clutch wedge assemblies 40 are held on the support elements 38. In the connected state of the parts 54 and 56 of the support device 16, the support elements 38 form a receptacle 66, 68 on the side surfaces of the support elements 38. These side surfaces of the support elements 38 have an extension in the radial direction and in the axial direction.

Protrusions 70 and 72 of the first connecting elements 42 of the clutch wedge assemblies 40 can be received in the receptacles 66 and 68. Due to the inclusion of the projections 70 and 72 in the receptacles 66 and 68 of the support elements 38 and the clamping force generated with the screws 58, the clutch wedge assemblies can be held on the support device 16 or on the support elements 38.

A summary of FIGS. 1 and 2 shows that the annular section 36 of the support device 16 extends radially on the outside around the flange arms 22, 24, 26, 30, 32 and 34 and the clutch wedge assemblies 40. The axial extent of the support device 16 overlaps with the axial extent of the flange arms 22, 24, 26, 30, 32, 34 and the axial extent of the coupling wedge packages 40. The annular section 36 extends along the radially outer ends of the support elements 38. The axial The extension of the support device 16 corresponds essentially to the axial extension of the clutch wedge assemblies 40 and the axial extension of the flange arms 22, 24, 26, 30, 32 and 34. The flange arms 22, 24, 26, 30, 32 and 34 are designed such that they extend from the hub-shaped section 18, 18 of the respective flange 12 or 14 into a region which is located radially and axially within the extent of the annular section 36 of the support device 12. The support device thus takes up no additional installation space, particularly in the axial direction. The support elements 38 hold the clutch wedge assemblies 40 in a predetermined radial position.

FIG. 3 shows a front view of the elastic coupling 10. In the view according to FIG. 3, the first flange 12 with its flange arms 22, 24 and 26 is shown completely. The flange arms 22, 24, 26 of the first flange 12 are connected to a flange arm 30, 32, 34 of the second flange 14 via two coupling wedge assemblies 40 and a support element 38. The support elements 38 extend in the circumferential direction between a flange arm 22, 24, 26 of the first flange 12 and a flange arm 30, 32 and 34 of the second flange 14. The flange arms 22, 24, 26, 30, 32 and 34 have on their radially outer The protrusions 50 end regions and 52, which engage in the recesses 48 on the first connecting element 44 of the clutch wedge assemblies 40. Each flange arm 22, 24, 26, 30, 32 and 34 is assigned two second connecting elements 44 of two clutch wedge assemblies 40 which follow one another in the circumferential direction. Each support element 38 is assigned two first connecting elements 42 of two clutch wedge assemblies 41 which follow one another in the circumferential direction. The first connecting elements 42 are connected to the side surfaces of the support elements 38 (see FIG. 2). The second connecting elements 44 are connected to the side surfaces of the flange arms 22, 24, 26, 30, 32 and 34. As a result, the clutch wedge assemblies 40 are held both axially and radially on the flange arms 22, 24, 26, 30, 32 and 34 and the support elements 38.

The radially outer sections of the pressure-preloaded clutch wedge assemblies 40 in the region of the support elements 38 and in the region of the flange arms 22, 24, 26, 30, 32 and 34 lie on a radius R around the central axis M. Coupling wedge packets 40 illustrates. The annular element 36 of the support device connects the support elements 38 to one another. The annular element 36 extends radially on the outside around the radial end faces of the flange arms 22, 24, 26 30, 32 and 34 and the clutch wedge assemblies 40. When the clutch 10 is in operation, some of the elastic elements or the clutch wedge assemblies 40 are subjected to pressure and part of the clutch wedge assemblies 40 are subjected to tension. Depending on their load (tension or pressure), the clutch wedge assemblies 40 could be pressed radially outwards without the support device 16 or pulled radially inwards. The support elements 38, together with the annular element 16, support the clutch wedge assemblies 40 in the radial direction and hold the clutch wedge assemblies in their predetermined radial position. The support elements 38 and the annular element 16 can thus prevent the coupling wedge packets during operation of the clutch 10 move in ler radia ^¬ inward or radially outward. By means of the support device 16, the available radial installation space can be optimally utilized and the bending angle! the elastic coupling 10 can be increased significantly. FIG. 4 shows a front view of an elastic coupling 10 according to a second embodiment. The elastic coupling 10 comprises a first flange 12, a second flange 14 and a support device 16. The first flange 12 has the central opening 20. Further openings or bores are formed along the edge of the opening 20.

The support device 16 has an annular section 36, starting from the support members 38 extend radially inward. The support elements 38 are connected to the flange arms 22 and 24 of the first flange and the flange arms 30 and 32 of the second flange 14 via elastic elements 74. The elastic elements 74 are designed in the form of thread-reinforced coupling elements 74. This type of thread-reinforced coupling elements is often referred to as a coupling tab.

The support device 16 is connected to each elastic element 74. Each support element 38 is connected to two elastic elements 74. The support element 38 is connected via the elastic elements 74 to a flange arm 22, 24 of the first flange and a flange arm 30, 32 of the second flange 14. The ring-shaped element 36 of the support device 16 extends in sections radially outside the elastic elements 74 and the flange arms 22, 24, 30, 32. The sum of the flange arms 22, 24, 30, 32 of the two flanges 12 and 14 corresponds to the sum of the support elements 38 A total of four flange arms 22, 24, 30, 32 are provided, which is why four support elements 38 are arranged. The support elements 38 are arranged in the circumferential direction between a flange arm 20, 22 of the first flange 12 and a flange arm 30, 32 of the second flange 14.

The axial extension of the support device 16 overlaps the axial extension of the flange arms 22, 24, 30, 32. The support device 16 thus takes up little installation space in the axial direction. The radial sections of the flange arms 22, 24 of the first flange 12, the flange arms 30, 32 of the second flange 14 and the support elements 38 have a common plane which runs perpendicular to the central axis M of the coupling 10. The support device 16 thus takes up little installation space in the axial direction, as a result of which the coupling ten takes up little overall installation space in the axial direction. The radially outer sections of the elastic elements 74 in the area of the support elements 38 and in the area of the flange arms 22, 24, 30, 32 lie on a radius R around the central axis M. The sections of the elastic elements 74 lying on the radius R make the polygon -Form of the arrangement of the elastic elements 74 illustrated.

FIG. 5 shows an enlarged detail from FIG. 4. In FIG. 5, the elastic elements 74 are shown in the form of thread-reinforced coupling elements. The elastic elements 74 represent a thread-reinforced coupling element 74 according to a first exemplary embodiment. The elastic elements 74 are screwed at one end to a support element 38 via the screws 78. With At their respective other ends, the elastic elements 74 are screwed via the screws 76 either to a flange arm 22, 24 (see FIG. 4) of the first flange 12 or to a flange arm 30, 32 of the second flange 14. The support elements 38 are arranged in the circumferential direction of the coupling 10 between a flange arm, here the flange arm 24 of the first flange 12, and a flange arm, here the flange arm 30, of the second flange 14. The support elements 38 extend radially inwards starting from the annular element 36 of the support device 16. The support device 16 holds the elastic elements 74 in their predetermined radial position, as a result of which the radial installation space is optimally used and the flexion angle which the coupling 10 can compensate for can be increased.

The support device 16 has a relatively short axial extent. The axial extension of the support device 16 can be matched to the axial extension of the flange arms 22, 24, 30, 32. The axial extension of the support device 16 overlaps with the axial extension of the flange arms 22, 24, 30, 32. The axial extension of the support device 16 overlaps in particular with the axial extension of the radial sections of the flange arms 22, 24, 30, 32. The annular element 36 the support device 16 extends radially outside the elastic elements 74 and the radial ends of the flange arms 22, 24, 30, 32.

Figure 6 shows a front view of an elastic coupling according to a third embodiment. In the elastic coupling 10 according to FIG

Flange arm 22, 24 of the first flange 12 and a flange arm 30, 32 of the second flange 14 and a support element 38 are connected via a single elastic element 74. The elastic elements 74 are designed as thread-reinforced coupling elements. Each thread-reinforced coupling element 74 has a thread package 80 and two bushings 82, which are wound around by the thread package 80. In addition, the thread-reinforced coupling elements 74 have a deflection element 84 which deflects the thread package 80 in the area between the two bushings 82. The thread package 80, the bushings 82 and the deflection element 84 are embedded in an elastic body 86. In the area between the bushings 82, the thread package 80 forms two strands 88a and 88b. The strands 88a and 88b run past the deflection element 84 or along the deflection element 84, but do not wrap around the deflection element 84. The deflection element 84 engages the strand 88b and forces this strand 88b in the direction of the strand 88a. As a result, the strands 88a and 88b take a bent course. The strand 88b is kinked more than the strand 88b. The strands 88a and 88b can abut one another in the region of the deflection element 84. The deflection element 84 is offset from the two bushings 82 arranged. The deflection element 84 forces the thread package 80 into an angled shape, so that the elastic element 74 according to this embodiment has an angled basic shape. The deflection element 84 divides the elastic element 74 into two legs, each of which has a bushing 82 and extends at an angle to one another.

The support elements 38 are connected to the deflection elements 84 by means of a screw or a bolt 78. The support elements 38 support the elastic elements 74 in the region between a first flange arm 22, 24 and a second flange arm 30, 32. As a result, the elastic elements 74 are also held in their predetermined radial position in the region between the flange arms 22, 24 and 30, 32. As a result, during operation of the coupling 10, the elastic elements 74 cannot contact the central axis M or the hub-shaped section of the flanges 12 or 14 (in FIG. 6 only the hub-shaped section 18 of the first one), particularly in the region between the flange arms 22, 24 and 30 Flange shown). The support elements 38 hold the elastic elements 74 in the angled shape, so that the installation space can be optimally used in the radial direction due to the overhung support device 16, which extends with its annular section 36 on the outside around the flange arms 22, 24, 30 and 32 , high flexion angles can be compensated.

The elastic elements 74 are connected to the screws or bolts 76

Flange arms 22, 24, 30, 32 screwed. Each flange arm 22, 24, 30, 32 is connected to two elastic elements 74, each of which extends in the direction of a flange arm 22, 24, 30, 32 of the other flange 12 or 14, and to this flange arm 22, 24, 30, 32 are connected. For example, the elastic elements 74 connected to the flange arm 22 of the first flange 12 extend to the flange arms 30 and 32 of the second flange 14. The elastic elements 74 are connected to these flange arms 22, 24, 30, 32.

The axial extension of the support device 16 overlaps with the axial extension of the flange arms 22, 24, 30, 32. In particular, the axial extension of the support device 16 overlaps with the axial extension of the radial sections of the flange arms 22, 24, 30, 32. The radial sections of the Flange arms 22, 24 of the first flange 12, the flange arms 30, 32 of the second flange 14 and the support elements 38 have a common plane which runs perpendicular to the central axis M of the coupling 10. The radially outer sections of the elastic elements 40 in the region of the support elements 38 and in the region of the flange arms 22, 24, 30, 32 lie on a radius R around the central axis M. According to this embodiment, a radially outer section is formed by the central region of the elastic elements 74, in which the deflection element 84 is arranged. The section of the elastic element 74 with the deflection element 84 thus forms a “corner” of the polygon shape. The polygon shape is indicated by the radius R on which the corresponding sections of the elastic elements 74 lie.

FIG. 7 shows a sectional view of a thread-reinforced joint device 100. The thread-reinforced joint device 100 has a plurality of thread packages 102 and a plurality of bushings 104. The thread packages 102 loop around two adjacent sockets 104. Each socket 104 is looped around two thread packages 102. The thread packages 102, which wrap around a bush 104, are arranged offset on the respective bush 104 in the axial direction. Starting from this bush 104, the two thread packs 104 extend in the direction of two different bushes 104, which are arranged offset in the circumferential direction to the bush 104 wrapped by the two thread packs 102.

The thread-reinforced joint device 100 has a support device 106.

The support device 106 has an annular section 108 which extends at least in sections radially on the outside around the thread packages 102 and the bushes 104. The support device 106 also has support elements 110. The support elements 110 extend radially inward from the annular section 108. Deflection elements 112 are provided at the radially inner end of the support elements 110, which act on the thread packages 102 in the area between two bushings 104. The deflection elements 112 are designed in the form of a socket.

The deflection elements 112 have a smaller diameter than the bushes 104. In the area between two bushes 104, a thread package 102 forms two strands 114 and 116. The deflection elements 112 engage the radially inner strand 116 and guide the strand 116 in the direction of the radially outer strand 114. In the area of the deflection elements 112, the two strands 114 and 116 can abut one another. The strand 116 runs kinked between the two bushes 104 due to the deflecting element 112. The support device 106 and the deflecting elements 112 prevent the thread packages 102 from being pulled radially inward during operation of the thread-reinforced joint device 100. The support device 106 with its support elements 110 and the deflection elements 112 accordingly ensures that the thread packages 102 are held in their predetermined radial position. In particular, the support device 106 ensures that the thread packages 102 do not migrate radially inward during operation of the thread-reinforced joint device 100 can. A closed ring is formed by the thread packages 102, which connects the bushings 104 to one another.

The thread packages 102 are secured to the bushes 104 in the axial direction via collar elements 118. The collar elements 118 can be disc-shaped or L-shaped in cross section. The collar elements 118 can be pressed onto the bushes 104. The thread-reinforced joint device 100 has the support device 106. The support device 106 has the support elements 110, which are arranged on both axial sides of the thread packages 102. This can be seen in particular from an overview of FIGS. 7 and 9.

The thread packages 134, 136 and 138 each wrap around one of the bushes 104. The thread package 134 arranged in a pull path extends in the axial direction between the two thread packages 136, 138 arranged in a push path around one of the bushes 104. Bundle elements 140, 142, 144 and 146 are arranged on the bushes 104 and hold the thread packages on the bushing 104.

The support plates 122 and 124 are arranged on the axial sides of the elastic bodies 120 and 178. The support plates 122 and 124 are connected to the elastic bodies 120, 178 via the deflection elements 188 and 190. In other words, the support device 106 couples the two elastic bodies 120, 178 to one another with the support plates 122, 124 and the deflection elements 188, 190. The elastic body 178 is provided radially inside the elastic body 120. According to this embodiment, the deflection elements 188 and 190 are of bolt-shaped design and are received in openings 194 in the support elements 130 of the support plates 122, 124. The support elements 188 and 190 each engage the radially inner strand 134b, 182b of the thread packages 134 and 182 and bring the radially inner strand 134b and 182b into contact with the radially outer strand 134a and 182a. This also applies to the other thread packages as shown in FIG. 16.

FIG. 19 shows a perspective view of the thread-reinforced joint device 100 according to FIGS. 15 to 18, which has two flanges 168 and 166. The two flanges 166 and 168 are designed as two-arm flanges and are connected to the two elastic bodies 120 and 178 via screws 174 and 176, respectively. For this purpose, the screws 174 and 176 extend through the bushings 104 and 180 (see FIGS. 15 to 18).

FIG. 20 shows a perspective view of the thread-reinforced joint device 100 according to FIGS. 15 to 18 in the state connected to two four-arm flanges 196, 198.

Of the four flange arms of flanges 196 and 198, two are short and two are long, "short" and "long" referring to the radial extension of the flange arms. The flange arms 200, 202 and 206, which are long in the radial direction, are connected to the radially outer elastic body 120. The short flange arm 204 of the flange 196 is connected to the radially inner elastic body 178. The radial extension of the flange arm 204 is accordingly shorter than that of the flange arms 200 and 202.

The embodiments shown in FIGS. 14 and 19 of a thread-reinforced joint device 100 with two-arm flanges 166, 168 can have a second-order rotational nonuniformity. If such rotational nonuniformity is not desired in certain applications, a thread-reinforced joint device 100 with the four-arm flanges 196, 198, as shown in FIG. 20, can be used. The four-arm flanges 196 and 198 have two flange arms 200, 202, 206 that are longer in the radial direction and two flange arms 204 that are shorter in the radial direction. With such four-arm flanges 196, 198, the rotational irregularity can be compensated for by the elastic bodies 120, 178 having the thread packages 134, 136, 138, 182, 184, 186. The flanges 196 and 198 are rotated 90 degrees to each other. The long flange arm 206 of the

Flange 198 is connected to the radially outer elastic body 120 via the screw 174.
