SPINDLE BEARING DEVICE, TEXTILE MACHINE AND METHOD FOR OPERATING A SPINDLE BEARING DEVICE AND USE OF AN O-RING ELEMENT}

The present invention provides, on the one hand, a spindle bearing device for mounting a spindle with a housing sleeve for holding a spindle collar unit and a spindle step unit. device, wherein the spindle step unit comprises a bearing bush element, the spindle axial bearing member for axially mounting the spindle in the bearing bush member and for radially mounting the spindle. A spindle bearing device is arranged in which a spindle radial bearing member is arranged together.

The invention, on the other hand, relates to a textile machine having at least one spinning, twisting or rewinding spindle.

The invention furthermore relates to a method of operating a spindle bearing device comprising a spindle collar unit and a spindle step unit for mounting a spindle on a textile machine, the spindle being, on the one hand, by a spindle axial bearing member and the Both axially and radially mounted by the spindle radial bearing member of the spindle step unit, on the other hand, additionally radially mounted by the spindle radial bearing mechanism of the spindle collar unit, the spindle axially The bearing member and the spindle radial bearing member are related to a method of operating a spindle bearing device, mounted in a bearing bush member of the spindle step unit.

Moreover, the present invention relates to the use of an O-ring element.

In particular, general spindle bearing devices are already well used in textile machines and are very well known from the prior art. However, these spindle bearing devices are generally very complicated and often show large differences between their suspension and damping properties, depending on the operating temperature.

For example, a spindle bearing device of this type for mounting a spinning, twisting or rewinding spindle is known from patent specification DE 44 27 311 C2 which discloses that both the spindle step and the spindle collar are fixed to the housing of the spindle bearing device. have. This spindle step has an outer tube and an inner tube, in which the inner tube consists of a sliding bearing bush, in addition to a disk-shaped axial bearing, for mounting each spindle axially and radially. Radial bearings are arranged. Between the inner tube and the outer tube a radially acting damping device in the form of a spiral-like element is arranged between which the oil or grease is located. Moreover, the radially acting spring member in the form of a spiral spring is additionally also located on both side heads of the spirally shaped member. The spindle step is rigidly connected to the housing of the spindle bearing device by an outer tube. This connection can also be reinforced by an outer tube having a cross section that deviates from the circular shape. While this spindle bearing device appears to be able to variably mount different spindles, the spindle bearing device exhibits suspension and damping properties that vary very disadvantageously with respect to varying operating temperatures. Moreover, this spindle bearing device is relatively complicated due to the presence of separate components, especially for the damping device acting in the radial direction.

It is an object of the present invention to at least overcome the above mentioned disadvantages of ordinary spindle bearing devices.

An object of the present invention is a spindle bearing device for mounting a spindle with a housing sleeve for holding a spindle collar unit and a spindle step unit, the spindle step unit comprising a bearing bush member, wherein the spindle is mounted within the bearing bush member. A spindle axial bearing member for axially mounting and a spindle radial bearing member for radially mounting the spindle are achieved by a spindle bearing device. According to the invention, a bearing bush member of a bearing step unit is arranged in a housing sleeve to be subjected to a prestress axially with respect to a spindle collar unit, said bearing bush member being located between the base region of the housing sleeve and the bearing bush member. Loading both by means of a first spring member, in particular a helical compression spring member, arranged by a second spring member, in particular an elastically deformable elastomer body member, arranged between the bearing bush member and the spindle collar unit to be loaded).

The concept "bearing bush member" in the sense of the present invention denotes a bush member in which the spindle axial bearing member and the spindle radial bearing member of the spindle bearing device are arranged together.

The bearing bush member is ideally inserted with play in the housing sleeve, and is therefore particularly movable radially.

The bearing bush member is preferably radially damped by oil, in particular a damping fluid formulation having damping properties is located in the oil gap between the housing sleeve and the bearing bush member in the peripheral region of the bearing bush member. Bearing bush member.

The spindle axial bearing member is preferably made of hardened steel and the spindle radial bearing member is preferably made of copper alloy, although other materials may also be used.

Prestress against the bearing bush member of the spindle step unit is very structurally very easy when a spring member, in particular a helical compression spring member, is arranged between the bearing bush member of the spindle step unit and the base area of the housing sleeve. Can be prepared.

Furthermore, it is advantageous for the bearing bush member to be precentered with the aid of this spring member with respect to the housing sleeve. For this purpose, the spring member is ideally arranged at least partially in the bearing bush member. As a result, the installation space can also be saved in the longitudinal size of the spindle bearing device, so that the spindle step unit can still be made more compact. This spring member is advantageously arranged at least partially in the housing sleeve of the spindle bearing device. Advantageously, for this purpose the base region has a thickness such that a spring member can be at least partially introduced and thus a material recess of suitable depth can be formed, for example in the form of a groove, which can be fixed radially within the housing sleeve. Equipped.

Moreover, another spring member, in particular an elastically deformable elastomer body member, is arranged between the bearing bush member and the spindle collar unit of the spindle step unit. For example, this other spring member in addition to the helical compression spring member significantly improves the axial damping ability of the spindle step unit relative to the bearing bush member. In other words, very good axial damping capability is achieved by this other spring member, which is sufficient for each spindle bearing device.

However, this other spring member, preferably provided as an elastomer body member, may also be formed identically to the spring member provided between the bearing bush member and the base region.

In an advantageous embodiment, the bearing bush member of the spindle step unit is rotatably arranged between the spindle collar unit and the base area of the housing sleeve with respect to the central axis of the spindle bearing device in the sense of slide coupling. By this type of arrangement the risk of jamming the bearing bush member, in particular in the housing sleeve, can be significantly reduced, for example when withdraw the sleeve. This creates a substantially stronger configuration mode of the spindle bearing device compared to known solutions, so that its operational reliability can be further increased.

In an advantageous embodiment the other spring member is further provided with a receiving area in the center for receiving the spindle, so that the spindle can be guided without problems to the spindle step unit. Moreover, as a result the lubricant in the spindle bearing device can be dispensed very well.

A variant of the preferred embodiment provides that the elastically deformable elastomeric body member comprises an O-ring member. The bearing bush member of the spindle step unit can be axially supported on the spindle collar unit very easily structurally by this type of O-ring member without the process obstructing the spindle installation space required to guide the spindle through.

The object of the invention is thus also achieved by using an O-ring member as axial and radial damping member in a spindle bearing device. The O-ring member can perform an operation of radially resetting the bearing bush member of the present spindle step unit with accurate spring stiffness.

The O-ring member can also concentrically surround this spindle installation space in a structurally simple manner and provide excellent support for the bearing bush member in the spindle collar unit.

Due to the two aforementioned mechanical spring members, in particular, a very reliable radial and axial reset of the bearing bush member and the spindle can be achieved so that an advantageous restoring torque always acts on the bearing bush member.

Moreover, the bearing bush member allows accurate spindle bearing seating, including a dimensionally stable plastic body, to deliver vibration damping to the damping medium without loss and to be economically manufactured through the opening by injection molding which is filled It is particularly advantageous to be able to escape air during the run and to allow oil circulation.

The bearing bush member also has a cross section that varies in the longitudinal direction. By means of the longitudinally varying cross-sectional type, the guide of the bearing bush member can be significantly improved with respect to the housing sleeve of the spindle bearing device.

Moreover, the bearing bush member has a larger outer diameter at the end facing the spindle collar unit than in the rest of the region. Excellent radial support of the bearing bush member on the housing sleeve is produced at opposite ends of the base region of the housing sleeve. This has a particularly advantageous effect on the correct centering of the bearing bush member in the housing sleeve of the spinning bearing device. Larger outer diameters result in collar parts that advantageously radially project from the bearing bush member. Due to the variable outer diameter along the longitudinal range of the bearing bush member, an adequately wide lubrication gap is always available between the housing sleeve of the spindle bearing device and this bearing bush member, in which the damping fluid formulation provides a good damping effect. It can be ensured in a structurally simple manner that it can be provided. Oil ISO VG10 can advantageously be used as damping fluid formulation.

Reduction of other components can be achieved in the present spindle bearing device when the spindle step unit is arranged so as not to be lost in the housing sleeve with the aid of the spindle collar unit.

In particular, conventional textile machines can be advantageously developed by the present spindle bearing device, and the object of the present invention is also provided with at least one spinning, twisting or rewinding spindle characterized by the spindle bearing device according to the invention. Is achieved by the weaving machine.

The object on which the present invention is based is also a method of operating a spindle bearing device comprising a spindle collar unit and a spindle step unit for mounting a spindle on a textile machine, on the one hand, the spindle is connected to a spindle axial bearing member. Both axially and radially by means of and by the spindle radial bearing member of the spindle step unit, on the other hand, additionally radially mounted by the spindle radial bearing mechanism of the spindle collar unit, The spindle axial bearing member and the spindle radial bearing member are mounted in a bearing bushing member of the spindle step unit, and according to the invention the bearing bushing member of the spindle stepping unit is according to various operating states of the spindle bearing device according to the present invention.It is achieved by the method in the ribs of operating a spindle bearing device to be displaced in the axial direction relative to the spindle collar unit. Particularly operable and reliable mounting of the spindle is produced regardless of the temperature conditions prevailing respectively in the spindle bearing device.

Again it is noted at this point that particularly balanced axial and radial damping can be advantageously achieved by the present spindle bearing device, and radial damping is substantially also achieved by a damping fluid formulation such as oil ISO VG10.

Other advantages, objects and features of the present invention are, for example, attached to which a spindle bearing device of a spindle step unit is provided with a bearing bushing member each having a bearing bush member arranged axially linearly with respect to the spindle collar unit. It is described with the aid of the drawings and the following detailed description. Consistent components in each drawing are not numbered or described in every drawing to avoid repetition.

4 is a third schematic assembly view of the spindle bearing device of FIGS. 1-3 with respect to a helical compression spring member inserted in the bearing bush member.
5 shows a fourth schematic assembly view of the spindle bearing device of FIGS. 1 to 4 with respect to a spindle step unit inserted into the housing sleeve and a spacer ring member inserted into the housing sleeve;
6 shows a fifth schematic assembly view of the spindle bearing device of FIGS. 1 to 5 with respect to the housing sleeve and the spindle step unit inserted therein into the O-ring member and the spindle collar unit of the spindle bearing device pressed into the housing sleeve;
7 is a longitudinal schematic cross-sectional view of another spindle bearing device for mounting a spinning spindle, including a bearing bush member of the spindle step unit arranged axially stressed against the spindle collar unit.

The first spindle bearing device 1 according to the invention shown in FIGS. 1 to 6 for mounting a spinning spindle (not shown) is according to the invention in a housing sleeve 3 of the spindle bearing device 1. And a spindle step unit 2 mounted under axial stress.

The spindle step unit 2 which is axially stressed can be displaced in the housing sleeve 3 due to the axial stress being axially in the axial direction 4 with respect to the central axis 5. The collar unit 6, on the other hand, is arranged to be at least partially pressed in the housing sleeve 3.

The bearing space 7 for the spindle step unit 2 is thus connected by the base region 8 of the housing sleeve 3, by the side wall region 9 of the housing sleeve 3 and into the housing sleeve 3. Constrained by the lower side 10 of the pressed spindle collar unit 6. The spindle step unit 2 is thus mounted not to be lost in the housing sleeve 3, in particular by the pressed spindle collar unit 6.

The spindle step unit 2 has an axial direction in which a spindle axial bearing member 12 for axially mounting the spindle and a spindle radial bearing member 13 for radially mounting the spinning spindle are arranged therein. It is characterized by a bearing bush member 11 subjected to linear stress. Conventional bearing members can advantageously be used as spindle axial bearing member 12 and spindle radial bearing member 13, which are not further described herein.

However, this member can also be made of, for example, a metallic material such as a ceramic material or a nonferrous metal material.

The bearing bush member 11 is further characterized as having a cross section 16 which is variable in the longitudinal direction 15.

This variable cross section 16 defines a larger outer diameter 18 in the bearing bush member 11 on the end 17 facing the spindle collar unit 6 than in the remaining area of the bearing bush member 11. The bearing bush member 11 can thus be more advantageously centered radially in the bearing space 7.

The appropriately wide gap 19 for damping fluid formulations (not shown), for example oil ISO VG10, is thus always present between the bearing bush member 11 and the housing sleeve 3.

Excellent exchange of the damping fluid formulation between the gap 19 and the inner region 20 in which the bearing bush member 11 and the spindle axial bearing member 12 and the spindle radial bearing member 13 are mounted is achieved. Guaranteed by the transverse bore 21 in the member 11, here only numbered as an example. These transverse bores 21 are advantageously located just below the end 17 with a larger outer diameter 18.

The elastically deformable elastomer body member 23 in the form of a spring member 22, in particular in a structurally simple O-ring member 24, comprises a spindle step unit 2 or a bearing bush member 11 and a spindle collar unit ( 6) advantageously arranged between.

By means of the O-ring member 24 in particular, the axial damping member 25 can be provided in a structurally particularly simple manner between the spindle step unit 2 and the spindle collar unit 6.

Furthermore, a receiving region 26 for receiving or guiding a spindle (not shown) along the central axis 5 may be provided by the O-ring member 24 at the center of the spring member 22.

Between the spindle step unit 2 and the base region 8 of the housing sleeve 3 is provided another spring member 30 in the form of a helical compression spring member 31.

In particular due to the mounting of the spindle step unit 2 in the housing sleeve 3 as described above, the spindle step unit 2 is provided between the spindle collar unit 6 and the base area 8 of the housing sleeve 3. It is arranged rotatably about the central axis 5 of the spindle bearing device 1, so that the risk of the spindle step unit 2 being tilted is virtually eliminated.

The helical compression spring member 31 is, on the one hand, mounted to the receiving region 32 in the bearing bush member 11, and the centering mandrel part 33 of the bearing bush member 11 also receives the receiving region ( 32). On the other hand, the helical compression spring member 31 is mounted to the base region 8 in the receiving bore 34.

The bearing bush member 11 is also fixed radially centered at the end 36 away from the spindle collar unit 6 by fixing the helical compression spring member 31 in the radial direction 35.

An approximately constant axial pressure prestress can be operably and reliably ensured by a helical compression spring member 31, preferably made of metal. On the other hand, radial damping independent of temperature can also be achieved by the spring member 22 described above, which radial damping behaves approximately in proportion to the damping capacity of the damping fluid formulation. The resetting capacity of the elastomeric body member 23 advantageously varies in proportion to the damping ability of the damping fluid formulation. This can be achieved, for example, when the elastomer body member 23 is made of thermoplastic polyurethane having a Shore A hardness of 55 to 80 Shore A. The elastomeric body member 23 is preferably configured in such a way that the Shore A hardness of the elastomeric body member 23 is reduced by 30% when the operating temperature of the spindle bearing device is increased from 20 ° C to 60 ° C.

The spinning spindle (not shown) has an additional mounting in the region of the spindle collar unit 6 of the spindle bearing device 1 by means of a roller bearing 36 in a manner known per se. The roller bearing 36 is pressed into the sleeve tube 37 of the spindle collar unit 6.

As can also be seen in FIG. 1, the spindle bearing device 1 is fixed by a clamping mechanism 40 in the holding device 41 of the textile machine 42.

2 to 6 show an advantageous assembly process of the spindle bearing device 1, but not all reference numbers in these figures are shown for clarity.

First of all, only the bearing bush member 11, the spindle axial bearing member 12 and the spindle radial bearing member 13 are shown in FIG. 2. The spindle axial bearing member 12 is first inserted into the bearing bush member 11 according to the assembly direction 50 and substantially aligned with the central axis 5 (see FIG. 1), and then the spindle radial bearing The member 13 is inserted and disposed in the inner region 20, which is the bearing member receiving space 43 of the bearing bush member 11.

Also visible here is a collar part 44 projecting radially at the end 17 of the bearing bush member 11, in which a larger outer diameter 18 is simply formed.

According to FIG. 3, the spindle axial bearing member 12 and the spindle radial bearing member 13 are already arranged in the bearing member receiving space 43 of the bearing bush member 11.

The bearing bush member 11 is then provided with a helical compression spring member 31 (see FIG. 4). This helical compression spring member 31 is inserted into the receiving area 32 of the bearing bush member 11 provided for this purpose.

According to FIG. 5, the bearing bush member 11 already assembled in this way is completed to form the spindle step mechanism 2 by the O-ring member 24, and then the bearing bush member 11 is helical compression spring. It is axially displaceable into the housing sleeve 3 of the spindle bearing device 1 until it is seated in the receiving bore 34 by the member 31.

Finally, the spindle collar unit 6 is also pressed into the housing sleeve 3 up to the peripheral web 45 of the sleeve tube 37 so that the ready-to-use spindle bearing device 1 ultimately Fully assembled (see FIG. 1).

The other spindle bearing device 101 shown in FIG. 7 for mounting the spinning spindle (not shown) of the textile machine 42 (see FIG. 1) also has a spindle step unit 102 and a spindle collar unit 106 inside. It has a housing sleeve 103 held in it. For this purpose the spindle collar unit 106 comprises a roller bearing 136 for additionally radially mounting the spindle. The spindle step unit 102 radially mounts the spindle axial bearing member 112 and the spinning spindle for axially mounting the spinning spindle, all mounted to the bearing bush member 111 of the spindle step unit 102. Spindle radial bearing member 113 for the purpose of assembly.

While the spindle collar unit 106 is pressed into the housing sleeve 103 and then fixed, the bearing bush member 111 of the spindle step unit 102 is axially oriented along the central axis 105 of the spindle bearing device 101. 104 is displaceably mounted in the housing sleeve 103.

A spacer ring member 165 is positioned between the spindle collar unit 106 and the spindle step unit 102, which is the base region 108 and the sidewall region 109 of the housing sleeve 103. Together to constrain the bearing space 107 for the bearing bush member 111.

The bearing bush member 111 forms a center part 166 having a bearing member receiving space 143 for mounting the spindle axial bearing member 112 and the spindle radial bearing member 113. A dimensionally stable plastic body 114 is provided. Optionally, the centering mandrel part 33 (not shown) (see FIG. 1) may also be adjacent to the center part 166. In any case, extending from this central part 166 in the longitudinal direction 115 of the bearing bush member 111, on the one hand, is the first concentrically peripheral wall web 167 with respect to the central axis 105, On the other hand, it is the second concentric peripheral wall web 168, so that the bearing area 132 for the spring member 122 and another receiving area 132A for another spring member 130 are bearings. It is formed on the bush member 111.

The bearing bush member 111 is thus mounted to the spindle bearing device 101 under linear stress in the axial direction.

The two spring members 122 and 130 used are the same helical compression spring member 131 with the same spring stiffness of c = 40 N / mm in this embodiment, so the final spring stiffness is c = 80 N /. It is produced for the bearing bush member 111 of mmm. This is independent of the amount of line stress. Depending on the design, other larger axial spring paths are also possible.

The rotation of the bearing bush member 111 together is ideally completely prevented by non-positive connection by forcing the spring members 122 and 130 during normal spinning operation. In the case of more flexible plastic materials, the stick-slip effect can advantageously occur, which ensures good static friction.

The radial reset force required for damping is also achieved independently of the amount of prestress. Excellent radial centering of the spring members 122 and 130 in the radial direction 135 is achieved by two centering disks 169 and 170, which overlie the base area 108 Centering disc 170 overlies spacer ring member 165. The centering disc can also be input directly during manufacture. The two spring members 122 and 130 are advantageously supported radially by two centering disks 169 and 170 on the housing sleeve 103.

The advantage of this second spindle bearing device 101 is that the spindle upper part is decoupled to axial vibration by two spring members 122 and 130 which in each case have a spring stiffness as high as half of the final one. In mode.

Moreover, the axial and radial suspension of the bearing bush member 111 is advantageously achieved by the same spring member 122, 130.

It is clear that the above described embodiment is only the first configuration of the spindle bearing device according to the invention in a textile machine. As such, the configuration of the present invention is not limited to these embodiments.
