Description

Mandrel bearing device, textile machine, and method for operating the spindle bearing device and use of O-ring components

One aspect of the present invention relates to a mandrel bearing device for mounting a mandrel having a shroud sleeve for holding a mandrel collar unit and a mandrel stage unit, wherein the mandrel The stage unit includes a bearing bushing member, a mandrel axial bearing member for axial mounting of the mandrel and a mandrel radial bearing member for radial mounting of the mandrel Arranged in the bearing bushing element.

Another aspect of the invention is directed to a textile machine having at least one spinning, twisting or rewinding mandrel.

Furthermore, the invention also relates to a method for operating a spindle bearing assembly comprising a spindle collar unit and a spindle stage unit for mounting a spindle on a textile machine, wherein the spindle One side is axially and radially mounted by a mandrel axial bearing element and by a mandrel radial bearing element of the mandrel stage unit, and on the other hand by one of the mandrel collar units The shaft radial bearing mechanism is additionally radially mounted, and wherein the spindle axial bearing element and the spindle radial bearing element are mounted in a bearing bushing element of the spindle stage unit.

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

In particular, conventional mandrel bearing devices have been successfully used on textile machines and are thus well known in the art. However, such mandrel bearing devices are generally quite complex, and depending on the operating temperature present, there is often a large difference between their suspension and damping characteristics.

For example, a spindle bearing device for mounting a spinning, twisting or rewinding mandrel, as known from DE 44 27 311 C2, wherein a mandrel stage member and a mandrel collar member are It is fixed in a casing of the spindle bearing device. The mandrel stage member has an outer tube member and an inner tube member, and is also disposed in the latter for axial and radial mounting of the individual mandrels, except for a disc-shaped axial bearing, and a sliding portion Radial bearings for bearing bushings. A damper device in the form of a radially acting helical element disposed between the inner tubular member and the outer tubular member is placed between the loops of the helical member as oil or grease. Furthermore, a radially acting spring element in the form of a helical spring is additionally provided on the side of the collar member on both sides of the helical element. The mandrel stage member is rigidly coupled to the outer casing of the spindle bearing assembly by the outer tubular member. This connection can also be reinforced by an outer tubular member having a cross-section that is detached from the circle. Although this mandrel bearing arrangement appears to be capable of different mounting of different mandrels, the mandrel bearing assembly may have unfavorable suspension and damping characteristics that vary greatly from each other at different operating temperatures. Moreover, such a mandrel bearing arrangement is quite complex, in particular due to the individual components associated with the radial acting damping device.

The object of the invention is to overcome at least the aforementioned disadvantages of conventional mandrel bearing arrangements.

The object of the present invention is achieved by a spindle bearing assembly for mounting a mandrel having a shroud sleeve for holding a mandrel collar unit and a mandrel stage unit, wherein The mandrel stage unit includes a bearing bushing member, a mandrel axial bearing member for axial mounting of the mandrel, and a mandrel radial bearing member for radial mounting of the mandrel Together they are arranged in the bearing bushing element. According to the invention, it is proposed that the bearing bushing element of the mandrel stage unit is configured to be axially pre-stressed relative to the mandrel collar unit in the shroud sleeve, the bearing bushing element being a spring element and a second spring element, the first spring element, in particular a helical compression spring element, disposed between the base region of the cover sleeve and the bearing bushing element, the first The two spring elements are in particular an elastically deformable elastomer element which is arranged between the bearing bushing element and the spindle collar unit.

The concept 〝 bearing bushing element 〞, in the context of the present invention, refers to a bushing element in which a mandrel axial bearing element and a mandrel radial bearing element are disposed together.

The bearing bushing element is ideally inserted into the shroud sleeve in a gap-like manner and is thus particularly radially movable.

The bearing bushing element of the present invention is preferably a bearing bushing element radially damped by oil, and a damping fluid agent having damping properties is placed therein, in particular placed between the shroud sleeves And between the bearing bushing elements in the oil gap on the circumference of the bearing bushing element.

The mandrel axial bearing element is here preferably made of a hardened steel, and the mandrel radial bearing element is preferably made of a copper alloy, although other materials may be used.

If a spring element, in particular a helical compression spring element, is disposed between the bearing bushing element of the mandrel stage unit and the base region of the shroud sleeve, a bearing bushing associated with the mandrel stage unit The preloading of the components can be fairly easily produced structurally.

It is further advantageous if the bearing bushing element is centered relative to the shroud sleeve by means of the spring element. For this purpose, the spring element is desirably configured to be at least partially in the bearing bushing element. As a result, the installation space in the longitudinal extent of the spindle bearing device can also be saved, so that the mandrel stage unit can be made smaller. It is advantageous if the spring element is at least partially arranged in the cover sleeve of the spindle bearing arrangement. For this purpose, the base region advantageously has a thickness such that a material groove of a suitable depth can be formed, for example in the form of a groove, which spring element can then be at least partially introduced therein. And can thus be fixed radially on the cover sleeve.

Furthermore, a further spring element, in particular an elastically deformable elastomer element, is arranged between the bearing bushing element of the spindle stage unit and the spindle collar unit. This further spring element, which is additionally provided, for example, outside the helical compression spring element, significantly improves the axial damping capacity of the spindle stage unit with respect to the bearing bushing element. In other words, by means of this further spring element, a fairly good axial damping capacity is achieved, which is sufficient for each of these mandrel bearing arrangements.

Preferably, however, the other spring element, which is provided as an elastomeric element, can also be formed in the same manner as the spring element provided between the bearing bushing element and the base region.

In an advantageous embodiment, the bearing bushing element of the spindle stage unit is rotatably configured in a sliding connection about a central axis of the spindle bearing assembly. Between the spindle collar unit and a base region of the shield sleeve. With this type of configuration, the risk of the bearing bushing element, in particular the risk of being caught in the shroud, for example when the bushing is pulled, can be substantially reduced. This results in a substantially more robust mode of construction of the mandrel bearing assembly than conventional solutions, so that operational reliability thereof can be further improved.

In an advantageous embodiment, it is further provided that the middle of the further spring element has a receiving area for receiving the mandrel such that the mandrel can be guided without problems with the mandrel stage unit. In addition, there may be a result of a good lubricant distribution in the spindle bearing assembly.

A preferred embodiment variant proposes that the elastically deformable elastomeric element comprises an O-ring element. The bearing bushing element of the mandrel stage unit can be axially supported on the mandrel collar unit in a structurally easy manner by means of an O-ring element of this type without clogging for guiding The process by which the mandrel mounts the space through the desired mandrel.

Thus far, the object of the invention has also been achieved by the use of an O-ring element as an axial and radial damping element in a spindle bearing arrangement. The O-ring element accomplishes radial resetting of the bearing bushing element of the present spindle stage unit having precise spring stiffness.

The O-ring element also concentrically surrounds the mandrel mounting space in a structurally simple manner and provides good support for the bearing bushing element on the mandrel collar unit.

Since the two aforementioned mechanical spring elements, in particular the bearing bushing element and one of the mandrels, a very reliable radial and axial resetting can be achieved, an advantageous restoring moment always acts on the bearing On the bushing element.

Furthermore, it is particularly advantageous if the bearing bushing element comprises a dimensionally stable body of plastic material, which can have a precise spindle bearing that transmits the vibration damping to the damping medium in a lossless manner, and It is possible to manufacture economically efficient openings with injection molding which allow air to escape during filling and which can have an oil circulation.

The bearing bushing element also has a cross section that varies in the longitudinal extent. The guiding of the bearing bushing element relative to the shroud sleeve of the mandrel bearing arrangement can be substantially improved by a cross-section of this variation in the longitudinal extent.

Furthermore, the bearing bushing element has a larger outer diameter than the other regions thereof at its end facing the mandrel collar unit. A good radial support of the bearing bushing element on the shroud sleeve is thus produced at the other end of the base region of the shroud sleeve. This has a particularly advantageous effect on a precise centering of the bearing bushing element in the shroud sleeve of the mandrel bearing arrangement. The larger outer diameter creates an advantageous radially protruding collar portion on the bearing bushing member. By virtue of the different outer diameters along the longitudinal extent of the bearing bushing element, it is ensured in a structurally simple manner that there is always enough between the bearing bushing element and the shroud sleeve of the mandrel bearing arrangement A wide lubrication gap, the damping fluid agent in the lubrication gap can have a good damping effect. The oil ISO VG10 can advantageously be used as the damping fluid agent.

If the mandrel stage unit is configured to be protected from loss by means of the mandrel collar unit, further component reduction can be achieved in the spindle bearing arrangement of the present invention.

Since in particular the conventional textile machine can be advantageously developed in the case of the spindle bearing device of the present invention, the object of the invention is also achieved by a textile machine having at least one spinning, crepe or rewinding mandrel. It is characterized by the spindle bearing device according to the invention of the present invention.

The object of the invention is based on and also by a method for operating a spindle bearing A method of apparatus is provided, the mandrel bearing assembly comprising a mandrel collar unit and a mandrel stage unit for mounting a mandrel on a textile machine, wherein the mandrel is supported by a mandrel axial bearing element And the mandrel radial bearing element of one of the mandrel stage units is simultaneously axially and radially mounted, and on the other hand by the mandrel radial bearing mechanism of the mandrel collar unit being additionally radially Mounting, and wherein the mandrel axial bearing element and the mandrel radial bearing element are mounted in a bearing bushing element of the mandrel stage unit, the bearing bushing of the mandrel stage unit in accordance with the present invention The sleeve member is axially displaced relative to the spindle collar unit in a cover sleeve of the spindle bearing assembly in accordance with different operating states of the spindle bearing assembly. Regardless of the individual temperature conditions present on the spindle bearing arrangement, one of the spindles is particularly operatively and reliably assembled.

In this context it should be pointed out again that a particularly balanced axial and radial damping can advantageously be achieved by the inventive spindle bearing arrangement, which can also be substantially achieved by a damping fluid agent such as oil ISO VG10. Was reached.

Further advantages, objects, and features of the present invention will be illustrated by the accompanying drawings and the following description, wherein by way of example, each has a core that is configured to be axially pre-compressed relative to a mandrel collar unit A spindle bearing assembly of a bearing bushing element of the shaft stage unit is shown and described.

When the axially pre-compressed mandrel stage unit 2 is displaceable in the shroud sleeve 3 due to this axial preload on the axial direction 4 of the associated one core axis 5, on the other hand, one heart The shaft collar unit 6 is configured to be at least partially pressed into the shroud sleeve 3.

In this regard, a bearing space 7 for the mandrel stage unit 2 is bounded by the base region 8 of the shroud sleeve 3, a side wall region 9 of the shroud sleeve 3, and pressed into the shroud sleeve 3 The lower side 10 of the mandrel collar unit 6 is defined. In this connection, the spindle stage unit 2 is locked in a manner in the protective sleeve 3 in a manner, in particular by the pressed spindle shaft unit 6 .

The mandrel stage unit 2 is characterized by an axially preloaded bearing bushing element 11, a mandrel axial bearing element 12 for the axial mounting of the mandrel and a spindle for the spinning spindle A radially mounted mandrel radial bearing element 13 is disposed in the bearing bushing element 11. Conventional bearing elements can advantageously be used as the mandrel axial bearing element 12 and the mandrel radial bearing element 13, and thus such bearing elements are not further described herein.

However, it may also be manufactured from a metal material or the like, for example, from a ceramic material or a non-ferrous metal material.

Furthermore, the bearing bushing element 11 is also characterized in that it has a cross section 16 that varies in the direction of its longitudinal extent 15.

This varying cross-section 16 at the end 17 of the bearing bushing element 11 facing the spindle collar unit 6 defines a larger outer diameter 18 than the rest of the bearing bushing element 11, thus the bearing lining The remaining area of the sleeve element 11 can be more advantageously radially centered in the bearing space 7.

In this case, a damping fluid agent for, for example, oil ISO VG10 (not shown here) A sufficiently wide gap 19, shown), is always present between the bearing bushing element 11 and the shroud sleeve 3.

A good replacement of the damping fluid between the gap 19 and the mandrel axial bearing element 12 and the inner region 20 of the bearing bushing element 11 in which the mandrel radial bearing element 13 is mounted It is ensured by the transverse through holes 21 in the bearing bushing element 11 (here only by way of example). Such lateral through holes 21 are advantageously disposed directly below the end portion 17 having the larger outer diameter 18.

In particular, a spring element 22 of an elastomeric element 23 in the form of a simple structural one O-ring element 24 is advantageously disposed on the spindle stage unit 2 or the bearing bushing element 11 and the spindle collar Between units 6.

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

Furthermore, a receiving region 26 for receiving or guiding the mandrel that is not introduced along the central axis 5 can be provided at the center by the O-ring member 24 relative to the spring member 22.

Provided between the mandrel stage unit 2 and the base region 8 of the shroud sleeve 3 is another spring element 30 in the form of a helically compressed spring element 31.

In particular, due to the above-described arrangement of the mandrel stage unit 2 in the shroud sleeve 3, the mandrel stage unit 2 is wound around the base of the mandrel collar unit 6 and the shroud sleeve 3 The central axis 5 of the spindle bearing device 1 between the regions 8 is rotatably arranged, so that the risk of tilting of the mandrel phase unit 2 is substantially eliminated.

The helical compression spring element 31 is mounted on the bearing bushing on the one hand In a receiving area 32 of the element 11, a certain core portion 33 of the bearing bushing element 11 also appears in the receiving area 32. In another aspect, the helical compression spring element 31 is mounted in the base region 8 in a receiving bore 34.

By means of the helical compression spring element 31 being fixed in this radial direction 35, the bearing bushing element 11 is also securely centered at its end 36 remote from the spindle collar unit 6.

A substantially constant axial pressure preload can be operatively and reliably ensured by the helically compressed spring element 31, preferably made of metal. On the other hand, a temperature-independent radial damping can also be achieved with the aforementioned spring element 22, which is approximately proportional to the damping capacity of the damping fluid agent. The ability to reset the elastomeric element 23 is advantageously proportional to the damping capacity of the damping fluid agent. This can be achieved, for example, if the elastomeric member 23 is made of a thermoplastic PU rubber having a hardness of 55 to 80 in a Class A of the Shore A. The elastomer member 23 is preferably constructed in such a manner that the Shore A hardness of the elastomer member 23 is reduced by 30% and the operating temperature of the spindle bearing device is increased from 20 ° C to 60 ° C.

The spinning spindle (not shown here) has a further 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. Assume. The roller bearing 36 is pressed into the sleeve tube 37 of the spindle collar unit 6.

As is also apparent from Fig. 1, the spindle bearing device 1 is held by a clamping mechanism 40 in a holding device 41 of a textile machine 42.

The preferred combination of one of the spindle bearing arrangements 1 is shown in accordance with the views of Figures 2 through 6, and for the sake of clarity, not all of the component symbols are indicated in such views.

First, only the bearing bushing element 11, the spindle axial bearing component 12 and The mandrel radial bearing element 13 is shown in FIG. The mandrel axial bearing element 12 is first inserted into the bearing bushing element 11 in a combined direction 50 that is generally aligned with the central axis 5 (see Fig. 1), followed by the mandrel radial bearing element 13, And placed in the inner region 20, the inner region 20 is also a bearing component receiving space 43 of the bearing bushing element 11 in each region.

The radially outer portion 18 of the larger outer diameter 18 that is simply formed on the end 17 of the bearing bushing member 11 is also clearly visible.

According to the view of FIG. 3, the spindle axial bearing element 12 and the spindle radial bearing element 13 have been arranged in the bearing element receiving space 43 of the bearing bushing element 11.

The bearing bushing element 11 is then equipped with the helical compression spring element 31 (see Fig. 4). This helical compression spring element 31 is inserted into this receiving region 32 of the bearing bushing element 11 provided for this purpose.

According to the view of Fig. 5, the bearing bushing element 11 and the O-ring element 24, which have thus been combined, are completed to form the mandrel stage unit 2 and are axially displaceably inserted into the spindle bearing In the shroud sleeve 3 of the device 1 until the bearing bushing element 11 is seated in the receiving bore 34 of the helical compression spring element 31.

Finally, the mandrel collar unit 6 is also pressed into the cover sleeve 3 up to the peripheral web 45 of one of the sleeve tubes 37, so that the ready-to-use spindle bearing device 1 finally appears. The complete is combined (see Figure 1).

Another spindle bearing device 101, shown in Figure 7 for mounting a spinning mandrel of one of the textile machines 42 (see Figure 1), also has a cover sleeve 103, a core The shaft stage unit 102 and a spindle collar unit 106 are clamped therein. The mandrel collar unit 106 for this purpose includes a roller bearing 136 for additional radial mounting of the mandrel. The mandrel The segment unit 102 includes a mandrel axial bearing member 112 for axial mounting of the spinning mandrel and a mandrel radial bearing member 113 for radial mounting of the spinning mandrel, both Both are mounted in a bearing bushing element 111 of the mandrel stage unit 102.

When the mandrel collar unit 106 is pressed into the shroud sleeve 103 and thus fixed, the bearing bushing element 111 of the mandrel stage unit 102 is displaceably mounted along the center The shield bearing sleeve 103 in the axial direction 104 of the central axis 105 of the shaft bearing device 101.

Disposed between the mandrel collar unit 106 and the mandrel stage unit 102 is a spacer ring member 165 that is defined for use with a base region 108 and a sidewall region 109 of the shroud sleeve 103 for One of the bearing bushing elements 111 has a bearing space 107.

The bearing bushing member 111 has a dimensionally stable plastic body 114 formed with a bearing member receiving space 143 for mounting the mandrel axial bearing member 112 and a central component of the spindle radial bearing member 113. 166. Alternatively, an unshown centering mandrel portion 33 (see FIG. 1) may also abut the center member 166. In any event, the central portion 166 extends over the longitudinal extent 115 of the bearing bushing member 111, on the one hand a first concentric peripheral wall wing member 167 associated with the central axis 105, and on the other hand a first Two concentric peripheral wall wings 168, such that a receiving area 132 for one spring element 122 and another receiving area 132A for the other spring element 130 are formed on the bearing bushing element 111.

To this end, the bearing bushing element 111 is then fitted into the spindle bearing device 101 in an axially preloaded manner.

The two spring elements 122 and 130 used in this embodiment are the same helical compression spring element 131 having the same spring stiffness C=40 N/mm, so that a resulting spring stiffness is related to the bearing bushing element 111. The spring stiffness C = 80 N/mm is produced. this Independent of the preload value. Other large axial spring paths are also possible in accordance with this design.

During a normal spinning operation, a common rotation of the bearing bushing elements 111 is desirably completely avoided by a non-forward connection of the spring elements 122, 130. In the case of softer plastic materials, a stick-slip effect can advantageously occur which ensures good static friction.

The radial reset force required for damping is also achieved independently of the preload value. A good radial centering for the spring elements 122 and 130 in the radial direction 135 is achieved by the two centering disc members 169 and 170, which are placed in the centering disc member 169. On the base region 108, the centering disc member 170 rests on the spacer ring member 165. These centering discs can also be placed directly in production. The two spring elements 122 and 130 are preferably radially supported by two centering disc members 169 and 170 on the shroud sleeve 103.

The second spindle bearing device 101 has the advantage of a compact structural mode and an axial vibration damping effect of the upper members of the two spring members 122 and 130, the spring members 122 and 130. It has a spring stiffness of half the result.

Furthermore, an axial and radial suspension of the bearing bushing element 111 is advantageously achieved by the same spring elements 122, 130.
