  The invention also relates to a textile machine comprising at least one spinning spindle, twisting spindle or rewinding spindle.

  The invention further provides a method of operating a spindle bearing device having a neck bearing unit and a base bearing unit for supporting a spindle in a textile machine, the spindle on one side being a spindle of the base bearing unit. Support axially and radially using thrust bearing elements and spindle radial bearing elements, and on the other side additionally support radially using the spindle radial bearing device of the neck bearing unit, The present invention relates to a method of supporting a spindle thrust bearing element and a spindle radial bearing element inside a bearing bush element of a base bearing unit.

  The invention further relates to the use of O-ring elements.

  In particular, the spindle bearing device mentioned at the beginning is already used effectively in textile machines and is therefore very well known on the basis of the prior art. However, such spindle bearing devices are often very complex in structure, and often have large differences in their spring and buffer characteristics depending on the operating temperature.

  For example, in a known spindle bearing device for supporting a spinning spindle, a twisting spindle or a rewinding spindle based on Patent Document 1, the base bearing and the neck bearing are fixed in the housing of the spindle bearing device. . The base bearing has an outer tube and an inner tube. In order to support each spindle in the axial direction and the radial direction, a radial bearing formed as a sliding bearing bush is also provided in addition to the disk-shaped thrust bearing.

  The object of the present invention is therefore to improve the spindle bearing device mentioned at the outset and to eliminate at least the drawbacks mentioned above.

  In order to solve this problem, in the configuration of the present invention, a spindle bearing device that supports a spindle and includes a housing sleeve for holding a neck bearing unit and a base bearing unit, the base bearing unit being a bearing bush element. In the spindle bearing device, a spindle thrust bearing element for supporting the spindle in the axial direction and a spindle radial bearing element for supporting the spindle in the radial direction are disposed together inside the bearing bush element. The bearing bushing element of the base bearing unit is axially pressed against the neck bearing unit and is arranged inside the housing sleeve, in which case the bearing bushing element comprises a bottom region of the housing sleeve, a bearing bushing element, Placed between First spring element, in particular a compression coil spring element, a second spring element disposed between the bearing bush element and the neck bearing unit, by a particular elastically deformable elastomeric body elements have been pressed.

  In the present invention, the concept of “bearing bush element” means a bush element in which a spindle thrust bearing element and a spindle radial bearing element of a spindle bearing device are arranged together.

  The bearing bushing element is ideally inserted in the housing sleeve with play, so that it is movable in particular in the radial direction.

  Preferably, the bearing bushing element according to the invention is a bearing bushing element that has a damping action in the radial direction using oil, in particular in the oil gap between the housing sleeve and the bearing bushing element. A buffer solution having a buffering action is accommodated around the bearing bushing element.

  In the present invention, the spindle thrust bearing element is preferably manufactured from hardened steel, and the spindle radial bearing element is preferably manufactured from a copper alloy, in which case other materials can also be used.

  If a spring element, in particular a compression coil spring element, is arranged between the bearing bushing element of the base bearing unit and the bottom area of the housing sleeve, the preloading on the bearing bushing element of the base bearing unit is very simple in structure. Can be born.

  Furthermore, it is advantageous if the bearing bushing element is pre-centered with respect to the housing sleeve using this spring element. For this purpose, the spring element is ideally arranged at least partly inside the bearing bushing element. Thereby, the base bearing unit can be configured more compactly. Preferably, the spring element is at least partly arranged inside the housing sleeve of the spindle bearing device. For this purpose, the bottom region has a thickness capable of forming a material notch of sufficient depth, for example formed as a groove, in which the spring element is at least partly formed. Can be inserted into the housing sleeve in a radial direction.

  Furthermore, another spring element, in particular an elastically deformable elastomer body element, is arranged between the bearing bush element and the neck bearing unit of the base bearing unit. This further spring element, for example provided in addition to the compression coil spring element, significantly improves the axial damping performance of the base bearing unit relative to the bearing bushing element. That is, this separate spring element provides a very good axial cushioning performance sufficient for each of the spindle radial bearing elements.

  Furthermore, the spring element, preferably formed as an elastomer body element, may however also be formed identically to the spring element provided between the bearing bushing element and the bottom region.

  In a preferred aspect of the invention, the bearing bushing element of the base bearing unit is rotatable between the neck bearing unit and the bottom region of the housing sleeve about a central axis of the spindle bearing device, such as a friction clutch. Is arranged. With such an arrangement, it is possible to significantly reduce the possibility that the bearing bush element will be caught inside the housing sleeve, for example, when the sleeve is pulled out. Furthermore, compared to known solutions, a very robust structural form of the spindle bearing device is obtained, so that the operational reliability of the spindle bearing device can be greatly increased.

  In another preferred aspect of the invention, the second spring element has a receiving area in the middle for receiving the spindle so that the spindle can be guided without problems until it reaches the base bearing unit. it can. This further allows a very good distribution of the lubricant inside the spindle bearing device.

  In a preferred aspect of the present invention, the elastically deformable elastomer body element as the second spring element includes an O-ring element. With such an O-ring element, the bearing bushing element of the base bearing unit is supported on the neck bearing unit in the axial direction in a significantly simpler manner without using the spindle structural space required to guide the spindle through. be able to.

  Therefore, the object of the present invention is also solved by using O-ring elements as thrust and radial buffer elements in a spindle bearing device. The O-ring element can satisfy the resilience in the radial direction of the bearing bushing element of the base bearing unit with accurate spring stiffness.

  Furthermore, the O-ring element surrounds this spindle structural space simply and concentrically in a structural manner, allowing a good support of the bearing bushing element in the neck bearing unit.

  In particular, the two spring elements mentioned above provide a very reliable radial and axial resiliency of the bearing bush element and spindle, so that a suitable return force always acts on the bearing bush element. .

  More particularly preferably, the bearing bushing element has a shape-stable plastic body, which enables a precise spindle bearing seat, transmits the vibration damping action to the buffer medium without loss and injection. The through holes can be manufactured at low cost by molding, and these through holes allow air to escape during filling and allow oil circulation.

  In another preferred aspect of the invention, the bearing bushing element has a cross section that varies in the longitudinal direction. Such a cross-section that varies in the longitudinal direction can significantly improve the guidance of the bearing bushing element relative to the housing sleeve of the spindle bearing device.

  In yet another preferred embodiment, the bearing bushing element has a larger outer diameter at the end directed towards the neck bearing unit than in other areas. With this construction, the bearing bushing element is well supported in the radial direction by the housing sleeve at the end of the bottom part of the housing sleeve, which is located on the opposite side of the end.

  This arrangement has a particularly advantageous effect on the precise centering of the bearing bushing element inside the housing sleeve of the spindle bearing device. A large outer diameter is obtained in the bearing bushing element, preferably by a radially projecting collar. Due to the outer diameter changing along the longitudinal direction of the bearing bushing element, the following can be easily assured structurally: That is, in this case, a sufficiently wide lubricant gap is always obtained between the bearing bush element and the housing sleeve of the spindle bearing device, and the buffer solution can exhibit a good buffering action in the lubricant gap. . As the buffer solution, for example, oil ISO VG10 can be preferably used.

  Further, when the base bearing unit is arranged in the housing sleeve using the neck bearing unit so as not to fall off, the number of constituent members can be further reduced in the spindle bearing device according to the present invention.

  In particular, a general purpose textile machine can be suitably further improved by means of a spindle bearing device according to the present invention, so that the object of the present invention is at least one spinning spindle, twisted spindle or It can also be solved by a textile machine with a winding spindle.

  The subject of the invention is also a method of operating a spindle bearing device having a neck bearing unit and a base bearing unit for supporting a spindle in a textile machine, the spindle on one side being a base bearing unit Are supported in the axial direction and in the radial direction by means of the spindle thrust bearing element and the spindle radial bearing element, and on the other side in the radial direction by means of the spindle radial bearing device of the neck bearing unit The spindle thrust bearing element and the spindle radial bearing element are also supported by the method of supporting the bearing bushing element of the base bearing unit. Of spindle bearing device S different in relation to the operating conditions, with respect to the neck bearing unit, adapted to move in the axial direction within the housing sleeve of the spindle bearing system. This makes it possible to support the spindle particularly reliably regardless of the respective temperature conditions in the spindle bearing device.

  In addition, with the spindle bearing device according to the present invention, particularly well-balanced thrust and radial buffer action can be suitably obtained. In this case, the radial buffer action is obtained mainly by a buffer solution such as oil ISO VG10, for example. It is done.

  Further advantages, objects and characteristics of the present invention will be described below with reference to the drawings, in which the base bearings are arranged axially pressed against the neck bearing unit. A spindle bearing device with one bearing bushing element of each unit is mentioned as an embodiment. In order to avoid repetition, the same constituent members in the individual drawings are omitted from the description and explanation in all the drawings.

It is a figure which shows the 5th assembly state of a bearing apparatus. FIG. 5 is a longitudinal sectional view showing another spindle bearing device for supporting a spinning spindle having a bearing bushing element of the base bearing unit, arranged preloaded in the axial direction with respect to the neck bearing unit.

  Next, embodiments of the present invention will be described with reference to the drawings.

  A first spindle bearing device 1 according to the invention for supporting a spinning spindle (not shown) shown in FIGS. 1 to 6 comprises a base bearing unit 2, which is in accordance with the invention. According to this, it is supported in the housing sleeve 3 of the spindle bearing device 1 by being preloaded in the axial direction.

  The base bearing unit 2 preloaded in the axial direction can move inside the housing sleeve 3 along the central axis 5 in the axial direction 4 on the basis of this axial preload, whereas the neck bearing unit 6 Are at least partially press-fitted into the housing sleeve 3.

  Thereby, the storage chamber 7 for the base bearing unit 2 includes a bottom region 8 of the housing sleeve 3, a side wall region 9 of the housing sleeve 3, and a lower surface 10 of the neck bearing unit 6 press-fitted into the housing sleeve 3. Is defined by Further, the base bearing unit 2 is supported in the housing sleeve 3, in particular, by the press-fitted neck bearing unit 6 so as to be prevented from falling off.

  The base bearing unit 2 is distinguished by a bearing bushing element 11 which is preloaded in the axial direction. Inside this bearing bushing element 11, there are a spindle thrust bearing element 12 for supporting the spindle in the axial direction and a spinning spindle. A spindle radial bearing element 13 which supports in the radial direction is arranged. As the spindle thrust bearing element 12 and the spindle radial bearing element 13, a general-purpose bearing element can be preferably used, and further description thereof will be omitted.

  However, the element may also be made from a metal material or the like, for example a material such as a ceramic material or a non-ferrous metal material.

  The bearing bushing element 11 is further distinguished by the fact that the bearing bushing element 11 has a cross-section 16 that varies in its longitudinal direction 15. This varying cross-section 16 establishes a larger outer diameter 18 at the end 17 of the bearing bushing element 11 facing the neck bearing unit 6 than at other areas of the bearing bushing element 11. As a result, the bearing bush element 11 can be centered in the radial direction, preferably inside the housing chamber 7.

  Thus, there is always a sufficiently wide gap 19 between the bearing bushing element 11 and the housing sleeve 3 for a buffer solution (not shown), for example oil ISO VG10.

  A good exchange of the buffer solution between this gap 19 and the inner region 20 of the bearing bushing element 11 in which the spindle thrust bearing element 12 and the spindle radial bearing element 13 are accommodated is a lateral change in the bearing bushing element 11. This is ensured by a hole 21 (here, by way of example only). These lateral holes 21 are preferably located directly below the end 17 having a large outer diameter 18.

  An elastically deformable elastomer body in which a spring element 22 is preferably formed as an O-ring element 24 having a simple structure between the base bearing unit 2 or the bearing bushing element 11 and the neck bearing unit 6. Element 23 is arranged. In particular, the O-ring element 24 makes it possible to prepare the axial cushioning element 25 between the base bearing unit 2 and the neck bearing unit 6 in a particularly simple structure.

  Furthermore, a receiving area 26 for receiving or penetrating a spindle (not shown) along the central axis 5 can be formed in the center of the spring element 22 using the O-ring element 24.

  Between the base bearing unit 2 and the bottom region 8 of the housing sleeve 3, another spring element 30 formed as a compression coil spring element 31 is provided. In particular, the base bearing unit 2 is supported in the housing sleeve 3 as described above, so that the base bearing unit 2 is positioned between the neck bearing unit 6 and the bottom region 8 of the housing sleeve 3 in a spindle bearing device. As a result, the possibility that the base bearing unit 2 is inclined is almost eliminated.

  The compression coil spring element 31 is housed in the housing area 32 inside the bearing bush element 11 on one side. In this case, the centering mandrel portion 33 of the bearing bush element 11 is further present in the housing area 32. To do. The compression coil spring element 31 is accommodated in the accommodation hole 34 in the bottom region 8 on the other side.

  This fixing of the compression coil spring element 31 in the radial direction 35 ensures that the bearing bushing element 11 is also centered in the radial direction at the end 36 opposite to the neck bearing unit 6.

  A compression coil spring element 31 which is preferably made of metal makes it possible to ensure a substantially constant axial preload in operation. On the other hand, the above-described spring element 22 can also provide a radial buffering effect that is independent of temperature, and this radial buffering function exhibits a characteristic that is substantially proportional to the buffering performance of the buffer solution. . Preferably, the restoration performance of the elastomer body element 23 changes in proportion to the buffer performance of the buffer solution. This can be obtained, for example, by the elastomer body element 23 being made from a thermoplastic polyurethane having a Shore A hardness of 55-80 Shore A. Preferably, the elastomer body element 23 is configured such that the Shore A hardness of the elastomer body element 23 is reduced by 30% as the operating temperature of the spindle bearing device increases from 20 ° C. to 60 ° C. Furthermore, a spinning spindle (not shown) is supported in a known manner by roller bearings 36 in the region of the neck bearing unit 6 of the spindle bearing device 1. The roller bearing 36 is press-fitted into the sleeve tube 37 of the neck bearing unit 6.

  As can be seen better from FIG. 1, the spindle bearing device 1 is fixed in the holding device 41 of the textile machine 42 using a tightening mechanism 40. FIGS. 2 to 6 show a preferred assembly sequence of the spindle bearing device 1, and in this case, in order to make the drawings easy to see, all reference numerals are omitted in all the drawings.

  2, only the bearing bush element 11, the spindle thrust bearing element 12 and the spindle radial bearing element 13 are shown. A spindle thrust bearing element 12 and then a spindle radial bearing element 13 are first inserted into the bearing bushing element 11 in a mounting direction 50 which is substantially aligned with the central axis 5 (see FIG. 1), and partly the bearing bushing element 11. The bearing element storage chamber 43 is also disposed in the inner region 20.

  The collar portion 44 projecting in the radial direction at the end 17 of the bearing bushing element 11 can also be seen well from the drawing. The large outer diameter 18 is easily formed by the collar portion 44.

  As shown in FIG. 3, the spindle thrust bearing element 12 and the spindle radial bearing element 13 are already arranged inside the bearing element receiving chamber 43 of the bearing bush element 11.

  The bearing bush element 11 is then provided with a compression coil spring element 31 (see FIG. 4). The compression coil spring element 31 is inserted into a receiving area 32 of the bearing bush element 11 provided for the compression coil spring element 31.

  As shown in FIG. 5, the bearing bush element 11 already assembled as described above becomes a complete base bearing unit 2 by including the O-ring element 24, and the compression coil spring element 31 of the bearing bush element 11 is accommodated. Until it is placed in the hole 34, it is slidably inserted in the housing sleeve 3 of the spindle bearing device 1 in the axial direction.

  Finally, the neck bearing unit 6 is further press-fitted into the housing sleeve 3 until the annular web 45 of the sleeve tube 37 abuts, whereby the spindle bearing device 1 (FIG. 1) finally ready for use. Reference) is fully assembled.

  Another spindle bearing device 101 for supporting a spinning spindle (not shown) of the textile machine 42 (see FIG. 1) shown in FIG. 7 likewise has a housing sleeve 103 in the housing sleeve 103. The base bearing unit 102 and the neck bearing unit 106 are held. The neck bearing unit 106 therefore has a roller bearing 136 for additionally supporting the spindle in the radial direction. The base bearing unit 102 includes a spindle thrust bearing element 112 for supporting the spinning spindle in the axial direction and a spindle radial bearing element 113 for supporting the spinning spindle in the radial direction. The bearing bush element 111 of the base bearing unit 102 is accommodated.

  The neck bearing unit 106 is press-fitted into the housing sleeve 103 and fixed thereby, whereas the bearing bushing element 111 of the base bearing unit 102 is axially extended along the central axis 105 of the spindle bearing device 101. A housing sleeve 103 is movably accommodated at 104.

  Located between the neck bearing unit 106 and the base bearing unit 102 is a spacer ring element 165 which, together with the bottom region 108 and the side wall region 109 of the housing sleeve 103, is a bearing bushing. A containment chamber 107 for the element 111 is defined.

  The bearing bushing element 111 has a shape-stable plastic body 114, which has a central portion 166 with a bearing element receiving chamber 143 for receiving the spindle thrust bearing element 112 and the spindle radial bearing element 113. Have In some cases, a centering mandrel portion 33 (see FIG. 1) (not shown) may be further connected to the central portion 166. In any case, from this central part 166, in the longitudinal direction 115 of the bearing bushing element 111, on one side a first concentric annular wall web 167 extends concentrically with respect to the central axis 105, And on the other side, a second concentric annular wall web 168 extends, so that the bearing bushing element 111 has a receiving area 132A for the spring element 122 and another spring element 130. Another storage area 132 is formed.

  Accordingly, the bearing bush element 111 is supported by being preloaded (pressed) in the axial direction in the spindle bearing device 1 also in this embodiment.

  The two spring elements 122, 130 used are in this embodiment the same compression coil spring element 131 with an equal spring stiffness of c = 40 N / mm, so that for the bearing bush element 111, c = A synthetic spring stiffness of 80 N / mm is produced. This composite spring stiffness is independent of the preload value. Depending on the design, larger axial spring strokes are possible.

  Due to the frictional coupling (transmission of force based on frictional force) by the spring elements 122 and 130, the bearing bushing element 111 is ideally completely prevented from rotating together in normal spinning operation. Softer plastics may preferably produce a stick-slip effect that helps for good static friction.

  The radial restoring force required for damping is likewise obtained independently of the preload value. For this purpose, a good radial centering of the spring elements 122, 130 in the radial direction 135 is obtained by two centering discs 169, 170, in which case the centering disc 169 contacts the bottom region 108 and the centering disc 170 is a spacer. It is in contact with the ring element 165. The centering disc may also be inserted directly during manufacture.

  Both spring elements 122, 130 are supported on the housing sleeve 103 in a good radial direction via two centering disks 169, 170.

  The advantage of the second spindle bearing device 101 is that the vibration in the axial direction of the upper part of the spindle is cut off by the compact structure type and the two spring elements 122 and 130 having the spring rigidity which is half the composite value. There is something you can do.

  Further, the spring elasticity in the axial direction and the radial direction of the bearing bush element 111 is preferably obtained by the same spring elements 122 and 130.

  Of course, the embodiment described above is merely one aspect of the spindle bearing device according to the invention in textile machines. Therefore, the configuration of the present invention is not limited to the illustrated embodiment.
