Disclosure of Invention

It is therefore an object of the present invention to provide an optimal solution for different applications of a gear motor at low cost.

According to the invention, this object is achieved by an adapter series according to the features given in claim 1, a gear motor according to the features given in claim 13 or 14 and a method according to the features given in claim 16.

In an adapter family for a gear motor comprising a first adapter and a second adapter, important features are:

(i) The first adapter has an adapter shaft, a first bearing and a housing, the housing comprising a first housing part and a second housing part,

wherein the first housing part is connected, in particular directly connected, to the second housing part, in particular for forming the housing,

wherein the inner ring of the first bearing is sleeved on the adapter shaft,

wherein the outer race of the first bearing is received in the first housing member and the second housing member and centers the first housing member with respect to the second housing member,

(ii) The second adapter has a second adapter shaft, a first bearing of the same construction as the first bearing and a second housing having a first housing part of the same construction as the first housing part, a second housing part of the same construction as the second housing part and an intermediate flange,

wherein the first housing part of the second adapter is connected, in particular directly connected, to an intermediate flange which is connected, in particular directly connected, to the second housing part on its side facing away from the first housing part, in particular in the axial direction, i.e. in the direction of the rotational axis of the second adapter shaft, in particular for forming the housing,

wherein the inner ring of the first bearing of the second adapter is fitted onto the adapter shaft,

wherein the outer ring of the first bearing of the second adapter is accommodated in the first housing part and the intermediate flange and centers the first housing part relative to the intermediate flange,

wherein a shaft sealing ring is received in the intermediate flange, or an overrunning clutch is received in the intermediate flange or integrated in the intermediate flange.

The advantage here is that by the optional introduction of the intermediate flange, additional functions, such as improved sealing by the shaft sealing ring or overrunning clutch, can be introduced without special additional costs. Thus, an optimal solution is always provided for different applications of the gear motor. In particular, the first adapter is very compact and the second adapter is implemented with additional functionality.

In an advantageous embodiment, the second housing part has a through-opening, in particular a radially through-opening,

wherein the through holes are spaced apart from each other in the circumferential direction, in particular uniformly,

in particular, wherein the through holes are all arranged at the same axial position,

in particular, wherein each through-hole is closed by a respective screw plug,

in particular, the bore axis of each through bore can be aligned with the screw axis of the clamping screw of the clamping ring of the first adapter or of the second adapter, which can be connected in a rotationally fixed manner to the adapter shaft, in a corresponding angular position of the adapter shaft. In this case, the advantage is that in the clamping connection on the motor side, the tool can be easily actuated by being inserted through the through-hole. However, in the case of a non-clamping connection, i.e. for example when using a key connection, in particular a step key connection, a second housing part can be used, i.e. no further housing part is required.

In an advantageous embodiment, in the first adapter, the outer ring of the first bearing is accommodated on the one hand in the bore of the first housing part and on the other hand in the bore of the second housing part,

wherein the sum of the hole depths of the two holes is equal to the axial length of the outer ring,

wherein in the second adapter the outer ring of the first bearing is received in the bore of the first housing part on the one hand and in the bore of the intermediate flange on the other hand,

wherein in the second adapter, the sum of the hole depths of the two holes is equal to the axial length of the outer ring, or the sum of the axial lengths of the outer ring of the first bearing and the outer ring of the overrunning clutch.

In an advantageous embodiment, the first adapter has an engagement part,

wherein the adapter shaft has a tooth-engaging portion, in particular a tooth-engaging portion which protrudes in the axial direction,

wherein the inner ring of the first bearing is fitted onto a bearing seat provided at the adapter shaft, in particular a finished bearing seat,

the bearing seat covers a first region in the axial direction, in which the bearing seat is configured to be uninterrupted in the circumferential direction, and a second region in which the bearing seat is configured to be interrupted in the circumferential direction, in particular a plurality of times.

In an advantageous embodiment of the adapter, which is provided in particular for a gear motor, has an adapter shaft and an engagement element and a bearing, in particular a rolling bearing,

wherein the adapter part has a tooth-engaging portion, in particular a tooth-engaging portion which protrudes in the axial direction,

wherein the inner ring of the bearing is fitted onto a bearing seat provided at the adapter shaft, in particular a finished bearing seat,

the bearing seat covers a first region in the axial direction, in which the bearing seat is configured to be uninterrupted in the circumferential direction, and a second region in which the bearing seat is configured to be interrupted in the circumferential direction, in particular a plurality of times.

The advantage here is that the adapter is very compact in structure. But here an interrupted bearing seat is provided. However, since the interrupted bearing seat is arranged in the region of the tooth insert, and the tooth insert is therefore already very stiff (since high torques have to be conducted), the bearing is accommodated sufficiently stably.

In an advantageous embodiment, a damping element is arranged between the tooth-insert of the coupling part and the tooth-insert of the adapter shaft,

in particular, the damping element has a base body and a radial region which is formed on the base body and protrudes in the radial direction,

wherein the radial region is axially disposed between each engagement member jaw and each adapter member jaw. In this case, the advantage is achieved that torque can be transmitted without play and torque fluctuations can be reduced.

In an advantageous embodiment, a circumferentially circumferential groove, in particular a turning groove, is formed on the adapter shaft between the first region and the second region in the axial direction. In this case, the bearing seat is also interrupted at this point, but the camber of the adapter shaft is spaced apart from the inner ring of the bearing in the region of the recess. In this case, such arching is caused when the tooth insert is elastically deflected, in particular when subjected to a torque impact.

In an advantageous embodiment, the region covered by the tooth insert in the axial direction comprises a second region and is spaced apart from the first region in the axial direction. The advantage here is that the bearing seat has two regions and the tooth insert is spaced apart from the uninterrupted region. This stable region is thereby decoupled from the elastically deflectable tooth.

In particular, the axial direction is parallel to the rotational axis of the adapter shaft, in particular wherein the circumferential direction and/or the radial distance is based on this rotational axis.

In an advantageous embodiment, the inner ring is limited on both sides in the axial direction by a snap ring. The advantage here is that the first bearing is embodied as a fixed bearing.

In an advantageous embodiment, the first snap ring is accommodated in a first annular groove of the adapter shaft, which is completely and/or uninterruptedly encircling in particular in the circumferential direction,

wherein the first annular groove is spaced apart from the first region and/or from the tooth insert in the axial direction. The advantage here is that the first snap ring is accommodated in a stable uninterrupted annular groove, but the second snap ring is accommodated in an interrupted annular groove, i.e. machined into the tooth insert.

In an advantageous embodiment, the second snap ring limits the inner ring, in particular on the side of the inner ring facing away from the first snap ring in the axial direction,

wherein the second snap ring is received in the second annular groove. The advantage here is that the inner ring of the bearing can be limited, even if such a limitation is arranged in a seat area which is embodied as a plurality of interruptions in the circumferential direction. Thereby, a particularly compact solution is achieved.

In an advantageous embodiment, the second annular groove is embodied as a circumferential interruption, in particular a plurality of times, and/or is arranged in the second region. The advantage here is that the adapter is embodied very compactly, since the inner ring of the bearing protrudes axially partially into the region of the tooth insert.

In an advantageous embodiment, the second annular groove is formed in the undercut of the adapter part and/or in the undercut of the coupling part. The advantage here is that the snap ring is securely accommodated in the axial direction.

In a further advantageous embodiment, the second annular groove is embodied to be uninterrupted in the circumferential direction and is machined into the engagement part. The advantage here is that the axial fastening is not realized directly in the adapter shaft, but in another component, namely the engagement component. Thereby, the inner ring protrudes even partly over the jaw region of the engagement part. Thereby, the structure of the adapter can be very compact.

In one advantageous embodiment, the adapter has a housing with a first housing part and a second housing part,

wherein the first housing part is connected with the second housing part,

wherein the outer race of the bearing is received in the first and second housing members and centers the first housing member relative to the second housing member. The advantage here is that the outer ring centers the two housing parts relative to one another. The bearing thus additionally assumes a centering function.

In an advantageous embodiment, the bearing is configured as a fixed bearing. The advantage here is that the bearing is axially fixed.

In an advantageous embodiment, the adapter has a second bearing, in particular a bearing designed as a floating bearing,

the outer race of the second bearing is received in the first housing member and the inner race of the second bearing is sleeved onto the adapter shaft,

in particular, a shaft sealing ring is accommodated in the first housing part, in particular on the side of the second bearing facing away from the engagement part, which shaft sealing ring seals against the adapter shaft, in particular the sealing lip thereof works on the adapter shaft.

In this case, the distance between the fixed bearing and the floating bearing can be changed in the event of a thermally induced change in length, since the floating bearing can be moved in the axial direction, in particular slightly.

An important feature in a gear motor with an adapter is that the gear motor has a motor and a gear reducer,

wherein the rotor shaft is connected to the coupling part in a rotationally fixed manner, in particular by means of a key connection,

the adapter shaft is connected to the input tooth part of the reduction gear in a rotationally fixed manner or is constructed in one piece, in particular integrally, with the input tooth part.

The advantage here is that the gear motor can be implemented as compactly as possible.

in particular, the step key connects the rotor shaft to the engagement element in a positive and/or rotationally fixed manner in the circumferential direction,

in particular, wherein the step key has an outer flange which protrudes radially outwards and which delimits the engagement member in the axial direction, the step key has an inner flange which protrudes radially inwards and which delimits the rotor shaft against the end face of the rotor shaft and/or against the inner flange in the axial direction,

in particular, wherein the region covered by the step key in the axial direction overlaps the region covered by the engagement member in the axial direction and overlaps the region covered by the rotor shaft in the axial direction, and/or overlaps the region covered by the adapter shaft in the axial direction,

in particular, the rotor shaft has a key groove for receiving a step key, which is embodied in a stepped manner in such a way that the inner flange is received in the key groove, in particular such that the inner flange is flush with the rotor shaft on the end face.

The advantage here is that not only can torque transmission be achieved by means of the step key, but also other functions, such as axial limiting and/or fastening, can be achieved. Thereby, a plurality of functions are integrated in the step key.

The essential feature in a gear motor according to claim 15 is that the gear motor has a motor and a reducer,

wherein the rotor shaft of the electric motor is connected to the hub part, in particular the coupling part, in a rotationally fixed manner, in particular by means of a key connection,

wherein the step key connects the rotor shaft to the hub part in a positive and/or rotationally fixed manner in the circumferential direction,

wherein the step key has an outer flange projecting radially outwards, which outer flange delimits the hub part in the axial direction, the step key has an inner flange projecting radially inwards, which inner flange delimits the rotor shaft against the end side of the rotor shaft and/or against the inner flange against the axial direction,

in particular, wherein the region covered by the step key in the axial direction overlaps the region covered by the hub member in the axial direction and overlaps the region covered by the rotor shaft in the axial direction,

in particular, the rotor shaft has a key groove for receiving a step key, which is embodied in a stepped manner in such a way that the inner flange is received in the key groove, in particular such that the inner flange is flush with the rotor shaft on the end side and/or the inner flange bears against the rotor shaft on the end side.

The advantage here is that not only can torque transmission be achieved by means of the step key, but also other functions, such as axial limiting and/or fastening, can be achieved. In this way, a plurality of functions are integrated in the step key, in particular so that the gear motor can be implemented in a compact manner as a whole. The step key according to the present invention is implemented to have an unusual geometry. The inner flange is spaced apart from the outer flange, in particular in the axial direction. Preferably, the inner flange is arranged at a first axial end region of the step key and the outer flange is arranged at the other axial end region of the step key.

Detailed Description

As shown in fig. 1 to 5, the adapter shaft 1 has, at its axial end region facing the engagement part 7, a tooth-like region 5, which overlaps with an axial region covered by a tooth-like region 8 of the engagement part 7.

The axial direction is here parallel to the axis of rotation of the adapter shaft 1. The radial distance is based on the rotational axis of the adapter shaft 1.

The damping member 6 is formed as a plastic star member. For this purpose, the damping element 6 has an annular base body, on which radially projecting radial regions are formed.

The base body is arranged radially inside the jaw portions 5 and 8. The radial distance area covered by the radial area in the radial direction comprises, or at least overlaps, the radial distance area covered by the claw portion 5 of the adapter shaft 1 in the radial direction and the radial distance area covered by the claw portion 8 of the engagement member 7 in the radial direction.

The damping element 6, in particular the radial region, is arranged in the circumferential direction between the tooth socket 5 of the adapter shaft 1 and the tooth socket 8 of the coupling part 7.

The radial region is spherically embodied in the radial direction. The wall thickness of the respective radial region measured in the circumferential direction thus has a local maximum in the radial direction.

The region covered by the claw portion 5 of the adapter shaft 1 in the axial direction overlaps the region covered by the claw portion 8 of the engagement member 7 in the axial direction.

The engagement member is fitted onto the rotor shaft 20, which protrudes through the engagement member 7 until it protrudes into the hollow region of the adapter shaft 1.

The rotor shaft 20 is connected in a rotationally fixed manner to the coupling part 7, in particular by means of a key connection.

A bearing is fitted over the adapter shaft 1, which bearing preferably serves as a fixed bearing.

For this purpose, the inner ring 3 of the bearing is fitted onto the adapter shaft 1 and is limited on both sides in the axial direction by means of two snap rings (2, 4).

The first snap ring 2 of the two snap rings (2, 4) is arranged in a first annular groove of the adapter shaft 1, wherein the first annular groove is spaced apart in the axial direction from the region covered in the axial direction by the tooth insert 5 of the adapter shaft 1. The first annular groove is thus embodied to completely surround in the circumferential direction without interruption.

The second snap ring 2 of the two snap rings (2, 4) is arranged in a second annular groove of the adapter shaft 1, wherein the second annular groove is arranged in the axial direction within the area covered in the axial direction by the tooth insert 5 of the adapter shaft 1. The second annular groove is thus embodied as a plurality of interruptions in the circumferential direction, since the tooth inserts 5 are spaced apart from one another in the circumferential direction, in particular uniformly.

Since the inner ring 3 of the bearing is fitted onto the adapter shaft 1 and contacts the adapter shaft 1 in the region axially between the two snap rings 2 and 4, the inner ring 3 is not supported in the region between the tooth inserts 5. The bearing support is thus embodied here as a plurality of discontinuities in the circumferential direction.

Thus, a bearing seat for receiving the inner ring 3 is formed on the adapter shaft 1 in the axial direction over a region overlapping the region covered by the tooth insert 5 of the adapter part 1 in the axial direction.

The bearing seat is thus embodied to be discontinuous in a first region and uninterrupted in another region.

The first region is 30% to 70% of the overall axial width of the bearing seat. The second area, i.e. the uninterrupted area, is the remaining part.

However, it is particularly preferred that the first region is less than half the entire axial width of the bearing seat, i.e. less than 50% of the entire axial width of the bearing seat.

As can be seen particularly clearly in fig. 5, which shows the region of fig. 4 in an enlarged manner, a circumferentially encircling recess 50 is embodied at the adapter part 1. Preferably, the recess 50 is machined, i.e. in particular embodied as a turned groove, by turning.

The turning groove 50 is arranged in the axial transition region between the first region and the further region. Thereby, the groove 50, in particular the turning groove, is arranged at the edge of the area covered by the tooth insert 5 in the axial direction.

The groove 50, in particular the turning groove, thus separates the region of the bearing seat that is interrupted in the circumferential direction from the rest of the bearing seat, i.e. the bearing seat region that is uninterrupted in the circumferential direction.

Thus, the groove 50 is arranged in the axial direction between the first annular groove for the first snap ring 2 and the second annular groove for the second snap ring 4.

As shown in fig. 3, a second bearing is fitted over the adapter shaft 1, which is accommodated in the second housing part 31 and serves as a floating bearing.

The second housing part 31 is connected to the first housing part 30, in particular by means of screws.

The inner ring 3 of the first bearing, although partly having an intermittent bearing seat as described above, is partly accommodated in the first housing part 30 and partly in the further housing part 31.

The outer ring of the first bearing thereby facilitates centering of the first housing part 30 relative to the second housing part 31. Furthermore, a shaft sealing ring 33, which seals against the adapter shaft 1, is accommodated in the first housing part 30. The first housing part can thereby be connected to the gear housing, the interior of which is at least partially filled with oil.

The adapter shaft extends into the reduction gear and is connected in a rotationally fixed manner to the input tooth part of the reduction gear.

Preferably, the outer diameter of the jaw 8 of the engagement part 7 is smaller than the net inner diameter of the second snap ring 4, which is received in a circumferentially discontinuous annular groove of the adapter part 1. Thus, it is not necessary to provide a tooth-insert region of the joint part

In other embodiments according to the invention, the input tooth part is embodied in one piece, i.e. integrally formed, with the adapter shaft 1.

In the embodiment according to fig. 6, unlike the embodiment according to fig. 2, the tooth-insert 5 of the adapter part does not pass axially through the inner ring 3, but rather the inner ring 3 protrudes axially beyond the adapter part 1 toward the engagement part 60, whose tooth-insert 8 is likewise correspondingly shorter than in fig. 2.

Thereby, the second snap ring 4 is received in the annular groove of the engagement member 60 and the inner ring 3 is restrained accordingly.

In this way, a clutch can be realized with a particularly small axial width, wherein the inner ring 3 is limited on the one hand by the first snap ring 2 received in the annular groove of the adapter part 1 and on the other hand by the second snap ring 4 received in the annular groove of the engagement part 60.

As can be seen in fig. 7, the outer ring of the first bearing is received in the bore of the first housing part 30 on the one hand and in the bore of the second housing part 31 on the other hand. The outer ring centers the two housing parts (30, 31) relative to each other.

As shown in fig. 8, in a further variant of the adapter, an intermediate flange 80 is arranged between the first housing part 30 and the second housing part 31, in which an axle sealing ring 81 is accommodated, which seals against the adapter axle 1. The sealing lip of the shaft sealing ring 81 thus works on the finished sealing surface of the adapter shaft 1.

In this variant according to fig. 8, the outer ring of the first bearing centers the intermediate flange 80 with respect to the second housing part 31, since it is received in the same bore of the intermediate flange 80 as the bore of the first housing part 30 on the one hand and in the bore of the second housing part 31 on the other hand.

The hole depth of the hole for receiving the intermediate flange 80 of the outer ring is equal to the hole depth of the hole of the first housing part 30, which is used as outer ring receptacle in the variant according to fig. 7.

In this way, therefore, the intermediate flange 80 replaces the first housing part 30 in terms of the reception of the outer ring of the first bearing.

These holes are embodied as blind holes and are defined explicitly by their diameter and hole depth.

In this way, therefore, the intermediate flange 80 facing the second housing part 31 is embodied identically to the first housing part 30 facing the second housing part 31.

The intermediate flange 80 has, on its side facing away from the second housing part 31, an axially projecting centering collar whose outer diameter is equal to the outer diameter of the outer ring of the first bearing and whose axial extension is equal to the bore depth of the bore of the first housing part 30 which is provided for receiving the outer ring of the first bearing in the embodiment according to fig. 7.

The intermediate flange 80 facing the first housing part 31 is thus embodied in the same way as an imaginary part facing the first housing part 31, which part consists of the second housing part 30 according to the embodiment according to fig. 7 and the outer ring of the first bearing, wherein the radial wall thickness of the centering flange can be smaller than the radial wall thickness of the outer ring.

As shown in fig. 9, instead of the shaft seal ring 81, an overrunning clutch, in particular a sprag overrunning clutch, may be accommodated, which has an inner ring 92 and an outer ring 90, as well as other components, such as sprags 91.

It is important here that the outer ring 90 of the overrunning clutch rests against a step of the intermediate flange 80, and that the outer ring of the first bearing rests against the outer ring 90 of the overrunning clutch and thus against the outer ring 90. Thus, the axial length of the outer ring 90 of the overrunning clutch is extended for this purpose by the hole depth of the hole facing the second housing part 31.

As shown in fig. 7 to 9, a key connection is implemented between the rotor shaft 20 and the engagement part 7. The keys are embodied here as stepped keys, i.e. with a monotonically increasing maximum radial distance from the axis of rotation of the rotor shaft 20 in the axial direction.

Thereby, the engagement member 7 can axially abut against the step of the key and in this way be positioned axially on the rotor shaft 20.

Nevertheless, the first housing part 30 still has four through-holes 100 which are spaced apart from one another in the circumferential direction, in particular uniformly.

As shown in fig. 10, instead of a key connection, the rotor shaft 20 can be connected to the coupling part 7 in a force-fitting manner by means of a clamping ring 103. To manipulate the clamping screw 102 of the clamping connection, a tool may be passed through one of the four through holes 100. At this time, in one angular position of the rotor shaft 20, the screw axis of the clamping screw 102 is aligned with the through-hole, in particular with the hole axis of the through-hole 100.

During operation, all through-holes 100 are closed by means of screw plugs inserted into the respective through-holes 100.

Since the second housing part 30 is identical in all adapters, in the variant of the adapter with a dog clutch, the second housing part 30 also has a through-hole 100 which is closed with a screw plug. Thus, only a few housing parts can be prepared for forming the family of adapters.

In other embodiments according to the invention, the tooth area of the adapter shaft 1 extends so far in the axial direction that the inner ring of the overrunning clutch is pushed onto the tooth area, i.e. the seat for the inner ring of the overrunning clutch is embodied as a discontinuity. As also in fig. 3, the inner ring 2 of the first bearing is embodied to be partially discontinuous and partially uninterrupted in the circumferential direction, since the inner ring 2 of the first bearing overlaps in the axial direction with the tooth region, i.e. with the region covered in the axial direction by the tooth insert 5 of the adapter shaft 1.

As shown in fig. 11 to 13, the step key 110 is embodied with an outer flange 130 protruding radially outward for axially positioning the engagement member 7 and an inner flange 132 protruding radially inward, which serves as a stop surface for the end side of the rotor shaft 20.

The torque-transmitting region 131 points in the circumferential direction, i.e. is embodied as a flat side of the step key 110, wherein the normal to this side is oriented tangentially.

The radial distance area covered by the step key 110 overlaps not only the radial distance area covered by the rotor shaft 20 but also the radial distance area covered by the engaging member 7.

Thus, the step key 110 extends not only into the key groove of the rotor shaft 20 but also into the key groove of the engaging member 7.

Since the engaging member 7 is restrained by the outer flange 130 in the axial direction by the engaging member 7 pressing the step key 110 in the axial direction while abutting against the outer flange 130 and thus pressing the inner flange 132 against the end side of the rotor shaft 20, the degree of freedom of movement of the engaging member 7 in the axial direction is restrained so that the claw portions (5, 8) cannot be moved away from each other in the axial direction. In this way, torque transmission, in particular of the tooth sockets (5, 8), is ensured by the step key 110.

In the region of the torque-transmitting region 131 that is covered in the axial direction, the step key 110 has a maximum radial extent, in particular a maximum radial wall thickness. Thus, a large torque can be transmitted through the step key 110. Only a small force is required for the axial positioning of the engagement member 7.

The key groove of the rotor shaft 20 is stepped in such a way that the inner flange 132 is accommodated flush at the end face.
