Description

[0001] SPINDLE BEARING DEVICE, TEXTILE MACHINE AND METHOD FOR OPERATING A SPINDLE BEARING DEVICE AND USE OF AN O-RING ELEMENT [0002] BACKGROUND OF THE INVENTION [0003]

The present invention is based, in the first place, on a spindle bearing device for mounting a spindle to a housing sleeve for holding a spindle collar unit and a spindle step unit. wherein the spindle step unit includes a bearing bushing element, a spindle axial bearing member for axially mounting the spindle in the bearing bushing member, and a radial bearing member for radially mounting the spindle Spindle radial bearing members are arranged together.

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

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

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

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

For example, this type of spindle bearing device for mounting a spinning, twisting or rewinding spindle is known from the 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. The spindle step includes an outer tube and an inner tube, and in the inner tube, in addition to the axial bearing in the form of a disc, for mounting axially and radially the respective spindle, is also constituted by a sliding bearing bush Radial bearings are arranged. Between the inner tube and the outer tube is arranged a damping device acting in the radial direction in the form of a spiral-like element with oil or grease between the windings. Furthermore, the spring members acting in the radial direction in the form of spiral spring are additionally located on both side of the spiral-shaped member. The spindle step is rigidly connected to the housing of the spindle bearing device by an outer tube. The connection may also be reinforced by an outer tube having a cross-section deviating from the circular shape. While this spindle bearing device appears to be able to variably mount different spindles, the spindle bearing devices exhibit suspension and damping characteristics that vary greatly with respect to varying operating temperatures. Moreover, this spindle bearing device is relatively complicated due to the presence of separate components, especially for damping devices acting in the radial direction.

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

It is an object of the present invention to provide a spindle bearing device for mounting a spindle in a housing sleeve for holding a spindle collar unit and a spindle step unit, said spindle step unit comprising a bearing bush member, A spindle bearing device for axially mounting a spindle axial bearing member and a spindle radial bearing member for radially mounting the spindle are arranged together. According to the invention, the bearing bush member of the bearing step unit is arranged to be axially prestressed with respect to the spindle collar unit in the housing sleeve, the bearing bush member being arranged between the base region of the housing sleeve and the bearing bush member In particular by means of a helical compression spring member arranged between the bearing bush member and the spindle collar unit, and by a second spring member, in particular an elastically deformable elastomeric body member, arranged between the bearing bush member and the spindle collar unit loaded.

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

The bearing bush member is ideally inserted with a clearance in the housing sleeve, and thus is particularly movable in the radial direction.

The present bearing bushing member is preferably radially damped by the oil and in particular a damping fluid formulation with damping characteristics is located in the oil gap between the housing sleeve and the bearing bushing member in the peripheral region of the bearing bushing member Which is a bearing bush member.

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

The application of a prestress to the bearing bush member of the spindle step unit is very easy structurally when the spring member, in particular the helical compression spring member, is arranged between the base region of the bearing bush member and the housing sleeve of the spindle step unit .

Furthermore, it is advantageous that the bearing bush member is previously centered with respect to the housing sleeve with the aid of this spring member. To this end, the spring members are ideally at least partially arranged in the bearing bush member. As a result, the installation space can also be reduced in the longitudinal dimension of the spindle bearing device, so that the spindle step unit can still be made more compact. This spring member is advantageously at least partially arranged in the housing sleeve of the spindle bearing device. Advantageously, for this purpose, the base region can have a thickness that allows the spring member to be at least partly introduced and thus can be fixed in the radial direction in the housing sleeve, for example in the form of grooves, Respectively.

Furthermore, other spring members, particularly elastically deformable elastomeric body members, are arranged between the bearing bush member and the spindle collar unit of the spindle step unit. For example, this other spring member additionally provided in the helical compression spring member significantly improves the axial damping capability of the spindle step unit with respect to the bearing bush member. In other words, a very good axial damping capability is achieved by this other spring member, which is sufficient for each of the spindle bearing devices.

However, this other spring member, which is preferably provided as an elastomeric body member, may also be formed the same as a 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 base region of the housing sleeve and the spindle color unit relative to the central axis of the spindle bearing device in the sense of slide coupling. With this type of arrangement, for example when withdrawing the sleeve, the risk of jamming of the bearing bush member particularly in the housing sleeve can be significantly reduced. This creates a substantially more robust configuration mode of the spindle bearing device compared to a known solution, and its operational reliability can be further increased.

In an advantageous embodiment, the further spring member is provided with a receiving area for receiving the spindle at its center, so that the spindle can be guided to the spindle step unit without any problem. Moreover, the result is that the lubricating oil in the spindle bearing device can be distributed 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 structurally very easily axially supported on the spindle collar unit by this type of O-ring member without a process interfering with the spindle installation space required to guide the spindle through.

As such, the object of the present invention is also achieved by using an O-ring member as an 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 also concentrically surrounds the spindle mounting space in a structurally simple manner and can better support the bearing bush member in the spindle collar unit.

With the two aforementioned mechanical spring members, it is possible to reliably and radially and axially resetting the bearing bush member and the spindle reliably, so that advantageous restoring torque always acts on the bearing bush member.

Moreover, the bearing bushing member can include a dimensionally stable plastic body to allow accurate spindle bearing seating to deliver vibration damping to the damping media without loss and can be economically manufactured through the opening by injection molding, It is particularly advantageous to allow the air to escape and enable oil circulation.

The bearing bush member also has a longitudinally varying cross-section. By virtue of the longitudinally varying cross-sectional type, the guide of the bearing bushing member can be significantly improved over the housing sleeve of the spindle bearing device.

Moreover, the bearing bushing member has a larger outer diameter at the end facing the spindle collar unit than at the remaining area. Supporting the bearing bush member in superior radial direction on the housing sleeve is created at the opposite end of the base region of the housing sleeve. This has a particularly advantageous effect on the precise centering of the bearing bush member within the housing sleeve of the spinning bearing device. A larger outer diameter results in a radially projecting collar part advantageously in the bearing bush member. By virtue of the outer diameter variable along the longitudinal extent of the bearing bush member, a suitably wide lubrication gap is always available between the housing sleeve of the spindle bearing device and the bearing bushing member in which the damping fluid formulation exhibits excellent damping effects Can be ensured in a structurally simple manner. The oil ISO VG10 can advantageously be used as a damping fluid formulation.

Reduction of other components can be achieved in the present spindle bearing device if 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, since a conventional textile machine can be advantageously developed by the present spindle bearing device, the object of the present invention is also achieved by providing at least one spinning, twisting, or rewinding spindle which features a spindle bearing device according to the present invention ≪ / RTI >

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, wherein the spindle is mounted on a spindle axial bearing member And both the spindle step unit and the spindle step unit are mounted both axially and radially by the spindle radial bearing member and on the other hand are 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 the bearing bush member of the spindle step unit and the bearing bush member of the spindle step unit according to the present invention is mounted on the housing of the spindle bearing device according to various operating conditions of the spindle bearing device,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 spindles is produced in each of the spindle bearing devices irrespective of the predominant temperature conditions.

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

Other advantages, objects and characteristics of the present invention are achieved by way of example and not by way of limitation, but by way of example only, with reference to the accompanying drawings in which a spindle bearing device, each having a bearing bushing member arranged to receive axial stress in relation to the spindle collar unit, The drawings and the following detailed description. Corresponding components in each figure are not numbered or described in all figures to avoid repetition.

Figure 6 is a fifth schematic assembly view of the spindle bearing device of Figures 1 to 5 with respect to the housing sleeve and the spindle step unit of the spindle step unit inserted into the O-ring member and the spindle color 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 a spindle step unit arranged to receive axial stress on the spindle collar unit;

A first spindle bearing device 1 according to the invention as shown in Figs. 1 to 6 for mounting a spinning spindle (not shown) is arranged in the housing sleeve 3 of the spindle bearing device 1 according to the invention And a spindle step unit 2 mounted so as to receive a linear stress in the axial direction.

The spindle step unit 2 subjected to the axial stress in the axial direction can be displaced in the housing sleeve 3 due to the axial stress 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 formed by the base region 8 of the housing sleeve 3 and by the side wall region 9 of the housing sleeve 3 and into the housing sleeve 3 Is limited by the lower side (10) of the pressed spindle collar unit (6). The spindle step unit 2 is mounted so as not to be lost in the housing sleeve 3 by the pressurized spindle collar unit 6 in particular.

The spindle step unit 2 includes a spindle axial bearing member 12 for axially mounting the spindle and a spindle radial bearing member 13 for radially mounting the spinning spindle, And a bearing bush member (11) subjected to a predetermined stress. Conventional bearing members can advantageously be used as the spindle axial bearing member 12 and the spindle radial bearing member 13, which are not further described herein.

However, the member may also be made of, for example, a ceramic material or a metallic material such as a non-ferrous metal material.

The bearing bush member (11) is further characterized by 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 bushing member 11 on the end 17 facing the spindle collar unit 6 than in the remaining areas of the bearing bushing member 11. [ So that the bearing bush member (11) can be more advantageously centered radially in the bearing space (7).

As such, a sufficiently wide gap 19 for a damping fluid formulation (not shown), such as, for example, the oil ISO VG10, is always present between the bearing bush member 11 and the housing sleeve 3.

Excellent exchange of the damping fluid formulation between the inner region 20 of the bearing bushing member 11 and the inner region 20 on which the spindle axial bearing member 12 and the spindle radial bearing member 13 are mounted and the gap 19, Is guaranteed by the transverse bore 21 in the member 11 (here only numbered as example). These transverse bores 21 are advantageously positioned directly beneath the end 17 having a larger outer diameter 18.

An elastically deformable elastomeric body member 23 in the form of a spring member 22 and in particular a structurally simple O-ring member 24 is mounted on the spindle step unit 2 or the bearing bush member 11 and the spindle collar unit 6).

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 area 26 for receiving or guiding a spindle (not shown) along the central axis 5 can be provided by the O-ring member 24 at the center with respect to 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.

The spindle step unit 2 is mounted between the base region 8 of the spindle collar unit 6 and the housing sleeve 3, in particular by mounting the spindle step unit 2 in the housing sleeve 3, Is arranged rotatably with respect to the central axis 5 of the spindle bearing device 1, thus virtually eliminating the risk that the spindle step unit 2 is tilted.

On the one hand, the helical compression spring member 31 is mounted on the receiving area 32 in the bearing bush member 11 and the centering mandrel part 33 of the bearing bush member 11 is also mounted on the receiving area 32 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 bushing member 11 is also fixed radially and centered on the end 36 remote from the spindle collar unit 6 by fixing the helical compression spring member 31 in the radial direction 35.

A substantially constant axial pressure line stress can be ensured to be operable and reliable by the helical compression spring member 31, which is preferably made of metal. On the other hand, temperature independent radial damping can also be achieved by the spring member 22 described above, which radially dampens behave roughly proportionally to the damping capability of the damping fluid formulation. The resilient ability of the elastomeric body member 23 advantageously varies proportionally with respect to the damping capability of the damping fluid formulation. This can be achieved, for example, when the elastomeric body member 23 is made of a thermoplastic polyurethane having a Shore A hardness of 55 to 80 Shore A. The elastomeric body member 23 is preferably constructed 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 占 폚 to 60 占 폚.

The spinning spindle (not shown) has an additional mounting in the area of the spindle collar unit 6 of the spindle bearing device 1 by 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.

1, the spindle bearing device 1 is secured by a clamping mechanism 40 in the holding device 41 of the textile machine 42. As shown in Fig.

Figures 2-6 illustrate the advantageous assembly process of the spindle bearing device 1, but not all reference numerals in these figures are shown for clarity.

First, only the bearing bushing member 11, the spindle axial bearing member 12 and the spindle radial bearing member 13 are shown in Fig. The spindle axial bearing member 12 is first inserted into the bearing bush member 11 along the assembly direction 50 and is substantially aligned with the central axis 5 (see Figure 1) The member 13 is inserted and disposed in the inner region 20 which is also the bearing member accommodation space 43 of the bearing bush member 11. [

The collar part 44 projecting radially at the end 17 of the bearing bush member 11, which is formed with a larger outer diameter 18, can also be seen here.

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. As shown in Fig.

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

5, the already assembled bearing bushing member 11 is completed to form the spindle step mechanism 2 by the O-ring member 24, Is displaceably inserted axially 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 to the peripheral web 45 of the sleeve tube 37 so that the ready-to-use spindle bearing device 1 is ultimately (See Figure 1).

The other spindle bearing device 101 shown in Fig. 7 for mounting a spinning spindle (not shown) of the textile machine 42 (see Fig. 1) also includes a spindle step unit 102 and a spindle collar unit 106, And a housing sleeve (103) To this end, the spindle collar unit 106 includes a roller bearing 136 for additionally radially mounting the spindle. The spindle step unit 102 includes a spindle axial bearing member 112 for axially mounting a spinning spindle, which is mounted on the bearing bush member 111 of the spindle step unit 102, And a spindle radial bearing member 113 for receiving the spindle radial bearing member.

The bearing bush member 111 of the spindle step unit 102 is axially movable along the central axis 105 of the spindle bearing device 101 while the spindle collar unit 106 is pressed into and then fixed into the housing sleeve 103 104 to be displaceably mounted within the housing sleeve 103.

A spacer ring member 165 is positioned between the spindle collar unit 106 and the spindle step unit 102. The spacer ring member 165 includes a base region 108 and a side wall region 109 of the housing sleeve 103, And restricts the bearing space 107 for the bearing bush member 111. [

The bearing bushing 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 And a plastic body 114 that is dimensionally stable. Alternatively, the centering mandrel part 33 (not shown) (see FIG. 1) may also be adjacent to the center part 166. In any event, extending from the central part 166 in the longitudinal direction 115 of the bearing bushing member 111 is on the one hand a first concentric 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 receiving area 132 for the spring member 122 and another receiving area 132A for another spring member 130, Is formed on the bush member (111).

As a result, the bearing bush member 111 is mounted to the spindle bearing device 101 under a stress in the axial direction.

The two spring members 122 and 130 used are the same helical compression spring members 131 having the same spring stiffness of c = 40 N / mm in this embodiment, so that the final spring stiffness is c = 80 N / mm < / RTI > It is independent of the amount of stress applied. Depending on the design, other larger axial spring paths are also possible.

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

The radial resetting force required for damping is also achieved independently of the amount of prestress. The excellent radial centering of the spring members 122 and 130 in the radial direction 135 is achieved by two centering discs 169 and 170 which center on the base area 108, The centering disk 170 is placed on the spacer ring member 165. The centering disc can also be input directly during manufacturing. The two spring members 122 and 130 are advantageously radially supported by two centering discs 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 the axial vibration by two spring members 122 and 130 which in each case have a spring stiffness as high as half the final one and a compact construction Mode.

Moreover, the axial and radial suspension of the bearing bushing member 111 is advantageously achieved by the same spring members 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 the textile machine. As such, the configuration of the present invention is not limited to these embodiments.
