Description

[0001] Exemplary embodiments of the present invention lie in the field of bearing arrangements, in particular bearing arrangements for supporting shafts that are subject to axial and radial loads.

[0002] Axial and radial load cases for bearings are known from the prior art. These can occur, for example, in transmissions, such as whenever the plane of rotation is changed via a gear ratio. This can occur, for instance, with bevel pinions in conjunction with ring gears. Such an arrangement is known, for example, from German patent application DE 198 39 481 C2. This document describes a transfer case for a motor vehicle with a bevel pinion shaft supported in a transmission housing by two spaced-apart and axially preloaded rolling bearings. The bevel pinion shaft is also equipped with a bevel pinion which drives a differential mounted in the transmission housing via a ring gear. Axle shafts are also mounted in the differential, which are operatively connected to each other via output and differential gears.The rolling bearings are designed as double-row tandem angular contact ball bearings, capable of bearing on one side only, and arranged in an O-arrangement relative to each other.

[0003] Furthermore, angular contact ball bearings are known, for example, from document DE 102 39 742 B4. This document shows a double angular contact ball bearing capable of bearing in one direction only, with a one-piece outer bearing ring and a one-piece inner bearing ring, as well as two ball cages arranged between the bearing rings. These cages contain bearing balls guided by two rows in cages. The bearing balls are supported on shoulders on the bearing rings that point in the direction of the applied force. The diameters of the bearing balls and the radii of their raceways are different, and both ball cages have different pitch circle radii. The two cages are designed as window cages made of a plastic material with pockets that receive the bearing balls and can be connected to one of the bearing rings to form a captive sub-bearing unit.This can be achieved by providing one of the two cages with several spacers at its axially inward-facing end, spacers that are uniformly spaced from one another circumferentially and prevent axial displacement of the other cage. The cage can also have several retaining lugs, uniformly spaced from one another circumferentially, which engage in a corresponding groove of the inner or outer bearing ring.

[0004] A disadvantage of these known concepts is that friction minimization and load optimization of these bearings are limited. In other words, the durability and resilience of these bearings can be further improved.

[0005] The object of the present invention is therefore to create an improved concept for a bearing that is subjected to loads in both radial and axial directions.

[0006] Exemplary embodiments of the present invention are based on the understanding that friction reduction or minimization, as well as load adaptation or optimization, can be improved in ball or rolling bearings when the loads act perpendicular to the bearings. In other words, it is understood that an angular contact ball bearing, by its very design, has a lower efficiency than a purely radially or axially loaded bearing. This is particularly true when multi-row angular contact ball bearings, such as tandem bearings, are used due to high loads. It is further understood that in a rolling bearing with more than one row of rolling elements, for example, a ball bearing with more than one row of balls, one row can be designed as an angular contact ball bearing, and another row as a purely radial or axial bearing.

[0007] Exemplary embodiments therefore provide a bearing arrangement for supporting a shaft with a bearing outer ring arrangement, a bearing inner ring arrangement, a first row of rolling elements for supporting the bearing outer ring arrangement relative to the bearing inner ring arrangement in an axial or radial direction, and a second row of rolling elements for supporting the bearing outer ring arrangement relative to the bearing inner ring arrangement in a direction that differs from the axial and radial directions.

[0008] All conceivable rolling bearings can be used, such as ball bearings, tapered roller bearings, cylindrical bearings, toroidal bearings, spherical roller bearings, etc. In exemplary embodiments, an outer ring bearing arrangement is mounted opposite an inner ring bearing arrangement with at least two rows of rolling elements, one of which is designed to support substantially radial or axial loads, and the other of which is designed to support loads from a different direction. In other words, an angle between the bearing rows can exist, which lies between 0° and 90°. In some exemplary embodiments, it is conceivable that one bearing row is a pure radial ball bearing and another bearing row is an angular contact bearing with an angle of almost 90°, i.e., also combined with an axial bearing to form a multi-row bearing unit or bearing arrangement.In exemplary embodiments, however, angles are conceivable that combine radial or axial components with intermediate angle components, i.e., with angles between 0 and 90°. The angle between the first, e.g., purely radial or axial, bearing row and the second bearing row is in the range 0 < α ≤ 90°, preferably it can be in the range 0 < α ≤ 65°.

[0009] Exemplary embodiments can therefore create a bearing arrangement that is compact despite the use of multi-row rolling elements. This allows for reduced assembly costs in some embodiments. In other embodiments, a higher power density can be achieved. This can be accomplished, for example, by enabling the bearing of higher loads within the same size, or by reducing the size while maintaining the same load capacity.

[0010] Exemplary embodiments thus create a bearing arrangement or bearing configuration designed as a multi-row bearing unit. The bearing unit therefore consists of at least one radial or axial bearing row and a further bearing row whose load direction forms an angle to the first bearing row between 0° and 90°.

[0011] In exemplary embodiments, the outer ring assembly of the bearing assembly can have two raceways for rolling elements of the first and second rows, and the outer ring assembly can be formed in one piece or in multiple pieces. In exemplary embodiments, the same can apply to the inner ring assembly, i.e., it too can have two raceways for rolling elements of the first and second rows, and the inner ring assembly can also be formed in one piece or in multiple pieces. Therefore, exemplary embodiments also include bearing units or bearing assemblies with a one-piece inner ring for at least two rows and a multi-piece outer ring, or bearing units with a one-piece outer ring and at least two rows with a multi-piece inner ring.

[0012] In further embodiments, as already mentioned above, the rolling elements of the first and second rows can be designed as balls, cones, cylinders, barrels, or needles, and the rolling elements of the first and second rows can be designed differently. In other words, these embodiments create bearing arrangements in which the first row comprises rolling elements of the same size and shape as the second row. In other embodiments, the rolling elements of the first and second rows can also be different. For example, it is conceivable that they have the same shape, such as a spherical shape, but differ in size. In further embodiments, it is conceivable that the rolling elements of the first row and the rolling elements of the second row also differ in shape.In such embodiments, for example, cylindrical rolling elements can be combined with balls, or similar.

[0013] In further embodiments, the outer ring assembly and / or the inner ring assembly can have a recess with a running surface for one of the rows of rolling elements. In other words, at least one of the running surfaces, or even both, can be directly integrated into the respective ring assembly. In other embodiments, at least one of the ring assemblies can be separated from the first or second row of rolling elements by a cup- or cup-shaped component. This component can, for example, be formed by a sheet metal part. The cup- or cup-shaped component can have at least one running surface for one of the rows of rolling elements. In other words, in embodiments, an additional component, for example in the form of a cup, can be provided to form at least one or both of the running surfaces.This component can then be installed either in the outer or inner bearing ring assembly to form the running surface.

[0014] In further embodiments, the bearing arrangement can include at least one cage for guiding the first or second row of rolling elements. Separate, combined, or coupled cages can be provided, adapted to the respective rolling elements and bearing ring arrangements. Such a bearing cage can have a guide element that interacts with the outer or inner ring arrangement to guide the bearing cage relative to the outer or inner ring arrangement. This can have the advantage that the raceway of the respective rolling elements can be guided relative to one of the bearing arrangements. This can lead to corresponding advantages with regard to wear and the durability of the bearing.Further embodiments provide a bearing arrangement for supporting a bevel pinion shaft, comprising a first bearing arrangement as described above and a second bearing arrangement. The first bearing arrangement is configured to support the bevel pinion shaft on a side facing the bevel pinion, and the second bearing arrangement is configured to support the bevel pinion shaft on a side facing away from the bevel pinion. Furthermore, in the first bearing arrangement, the first row of rolling elements can be located on the side of the bearing arrangement facing the bevel pinion. Accordingly, the second row of rolling elements in the first bearing arrangement can be located further away from the bevel pinion than the first row. In some embodiments, the second row of rolling elements can therefore also be located on the side of the bearing arrangement facing away from the bevel pinion.

[0015] In other words, exemplary embodiments can provide for the rolling bearing of a bevel pinion shaft, for example, in a motor vehicle (motor vehicle) drivetrain. The bevel pinion shaft can be supported, for example, relative to a housing, using multiple bearing arrangements. In exemplary embodiments, such a bearing arrangement can include a rigid or deformable spacer between the first and second bearing arrangements. Such a spacer can offer the advantage of maintaining a defined distance between the two bearing arrangements, allowing the corresponding bearing surfaces relative to the housing and the corresponding force distribution to be defined or adjusted. Therefore, in exemplary embodiments, the rolling bearing arrangement can include a deformable spacer between the two bearings or bearing arrangements. In other words, the spacer can be deformable.

[0016] In further embodiments, the bearing arrangement can also include a preload element designed to axially preload the first bearing arrangement relative to the second. In this respect, the preload element can be used to deform the spacer, i.e., to apply an axial preload to both bearing arrangements and the spacer between them. Therefore, embodiments can also create a rolling bearing arrangement with a preload element mounted on the shaft to axially preload the two bearing arrangements on either side of the bevel pinion shaft. A screw element, for example, can be used for this purpose. As mentioned above, embodiments of the bearing arrangement as a rolling bearing arrangement can, for example, be used on the pinion head side of a pinion shaft.Another rolling bearing or rolling bearing arrangement can be used on the corresponding opposite side. This second bearing arrangement can, for example, comprise an angular contact bearing, a thrust bearing, a radial bearing, a bearing arrangement as described above, or a bearing arrangement arranged as a mirror image of the first bearing arrangement. For example, angular contact ball bearings can also be used here. As already mentioned, in exemplary embodiments, rolling bearing arrangements of the same principle can occur on both sides of the pinion shaft.

[0017] In some embodiments, a rolling bearing of the same principle, comprising a one-piece outer ring and a one-piece inner ring, can be used on both sides of the pinion shaft. In further embodiments, the respective bearing or bearing arrangement can be sealed, oil-lubricated, grease-lubricated, etc. Furthermore, a housing for the bearing, i.e., for example, the bearing ring arrangement or a housing in which the corresponding bearing arrangement is mounted, can be made of metal, e.g., a light metal such as aluminum. Embodiments also provide a bevel pinion shaft with at least one inner bearing ring of the first or the second bearing arrangement according to one of the bearing arrangements described above. This can offer the advantage of reducing manufacturing costs, since the inner bearing ring arrangement is provided directly on the bevel pinion shaft.

[0035] Fig. 1 shows a storage 100 for the bearing of a shaft 200 , which in the present embodiment is designed as a bevel pinion shaft. The bearing arrangement 100includes a bearing outer ring arrangement 110 and a bearing inner ring arrangement 120 . Between the outer bearing ring arrangement 110 and the bearing inner ring arrangement 120 There is a first row of rolling elements 130 for the storage of the outer bearing ring assembly 110 opposite the inner ring bearing arrangement 120 in an axial or radial direction, wherein in the exemplary embodiment the Fig. 1. First, the radial direction is illustrated, as is the corresponding axis. 132 illustrated. The storage arrangement 100 It also includes a second row of rolling elements. 140 for the storage of the outer bearing ring assembly 110 opposite the inner ring bearing arrangement 120 in a direction that differs from the axial or radial direction 132 differs. This is in the Fig. 1 through the inclined axis 142illustrated, which in this embodiment runs at least approximately in the direction of 45°. Fig. Figure 1 further shows that the bearing outer ring arrangement 110 in a case 300 is attached.

[0036] The storage arrangement 100 The bevel pinion shaft is thus supported 200 , which in the exemplary embodiment of the Fig. 1. A conical pinion on the right side 210 includes, opposite the housing 300 Therefore, the Fig. 1 also a bearing for the bearing of the bevel pinion shaft 200 with the first storage arrangement 100 according to the above description and a second storage arrangement 400 The second bearing arrangement also supports the shaft. 200 opposite the case 300 In the exemplary embodiment of the Fig. 1 is the second storage 400 as a radial ball bearing with an outer ring 410 , an inner ring 420and a row of rolling elements 430 trained. The second storage arrangement 400 It rests on a wave shoulder and is secured with a clamping ring. 440 attached.

[0037] As the Fig. 1 further shows, is the first storage arrangement 100 for the bearing of the bevel pinion shaft 200 on one of the conical pinions 210 facing side formed and the second bearing arrangement 400 for the bearing of the bevel pinion shaft 200 on one of the conical pinions 210 formed on the opposite side. The three rows of rolling bearings in total. 130 , 140 and 430 are in the exemplary embodiment of the Fig. 1 each designed as a ball bearing. As the further embodiments will show, all possible variants of bearings and rolling elements can be used here.

[0038] The following describes several exemplary embodiments, some of which have the same components as the exemplary embodiment of Fig. 1. Identical reference symbols denote identical components. For the sake of clarity, multiple descriptions and repeated naming of all components are sometimes omitted.

[0039] The Fig. Figure 2 illustrates another embodiment of a bearing 500 a bevel pinion shaft 200 The first storage arrangement 100 is identical to the first bearing arrangement 100 the Fig. 1. To illustrate the different angles / load directions, the following is shown in the Fig. 2 the angle α is drawn, which represents the inclination of the load with respect to the second row of balls. 140 opposite the first row of balls 130 clarifies. In the exemplary embodiment of the Fig. Furthermore, 2 is the second storage arrangement 400 It is designed as an angular contact ball bearing. This is achieved through the inclined load axis. 432 This clarifies the point. It thus becomes clear once again that the storage unit or storage arrangement... 100 This embodiment also consists of a radial bearing series, which in the embodiment of Fig. 1 with 130 is designated, and at least one further bearing row 140 includes those whose load direction forms an angle to this, in this embodiment, purely radial bearing row 130 exhibits an angle of 0 < α ≤ 90°. Exemplary embodiments are not limited to two rows of rolling elements. The angle between the first, e.g., purely radial or axial, row of bearings 130 and the second row of storage 140 is located in the range 0 < α ≤ 90°, but preferably in the range 0 < α ≤ 65°.

[0040] The Fig. Figure 3 illustrates another embodiment, in which again a storage 500 for a bevel pinion shaft 200 with a bevel gear 210 is shown. In the exemplary embodiment of the Fig. 3 includes the first storage arrangement 100 now three rows of rolling bearings 130 , 140 and 150 The first row of rolling bearings is... 130 radially loaded like the axis 132 shows and the two subsequent rows of rolling bearings 140 and 150 are loaded at an angle, like their two axes 142 and 152 show. Furthermore, it should be noted that the rows of rolling elements 140 and 150 differ in their diameters, i.e., in this embodiment, the balls of the rolling element row 150 smaller than the balls of the rolling element row 140 The exemplary embodiment of the Fig. Figure 3 further illustrates a second storage arrangement 400, which are radial ball bearings with the rolling element series 430 is trained. Fig. Figure 3 further illustrates that between the first storage arrangement 100 and the second storage arrangement 400 a spacer 600 This spacer is located. 600 is shown here as deformable and holds the two bearing arrangements. 100 and 400 at a distance. In this respect, the clamping ring, which also acts as a preload element, exerts pressure. 610 This can be described as an axial force acting on the bearing arrangement. 400 and indirectly via the spacer element 600 also on the storage arrangement 100 out. The two storage arrangements 100 and 400 They can therefore be held under axial preload.

[0041] As the examples of implementation of the Fig. 1, Fig. 2 and Fig. 3 show, can be used within the framework of the storage arrangement 100 the respective inner bearing rings 120as well as the outer bearing rings 110 They can be formed in one piece. Furthermore, the bearing rings, each formed in one piece, can provide corresponding running surfaces for the rolling elements. Thus, the outer bearing ring arrangements feature 110 at least two running surfaces for rolling elements of the first and second rows of rolling elements 130 , 140 The same applies to the inner ring bearing arrangement. 120 This can be observed in the previously considered embodiments, as these also have corresponding running surfaces for the rolling elements of the first and second rows of rolling elements. 130 and 140 on.

[0042] Another embodiment is shown in the Fig. 4 shown. The exemplary embodiment of the Fig. 4 again shows the storage 500 a bevel pinion shaft 200 with a bevel gear 210, as can occur, for example, in a vehicle powertrain. In the embodiment described in the Fig. As shown in section 4, the two bearing arrangements are shown. 100 and 400 symmetrically constructed. In other words, the bearing arrangement is 400 on the other side of the pinion shaft 200 , i.e. on the bevel gear 210 opposite side, rotated 180° compared to the bearing arrangement 100 built-in. Besides this option, there is also the option of identical orientation, i.e., the use of identical bearing arrangements. 100 and 400 Possible in exemplary embodiments.

[0043] The Fig. Figure 5 illustrates a further embodiment, which is based on the embodiment of the Fig. 4 builds upon. Unlike the Fig. 4 use the two bearing arrangements 100 and 400 in the exemplary embodiment of the Fig. 5 a common bearing outer ring, i.e. a common bearing outer ring arrangement 110 . As the Fig. Figure 5 shows that all running surfaces for the four rows of rolling elements are formed in the common outer ring bearing arrangement. Therefore, the bearing arrangement includes 100 in the Fig. 5. A one-piece outer ring for at least two bearing rows and a multi-piece inner ring. In other embodiments, a one-piece inner ring for at least two bearing rows and a multi-piece outer ring are also conceivable.

The second row of rolling elements 140It is designed as a series of ball bearings. In general, in exemplary embodiments, the rolling elements of the first and second rows of rolling elements can be... 130 , 140 for example, they can be shaped as spheres, cones, cylinders, barrels, or needles. As illustrated by the exemplary embodiment of the Fig. As shown in Figure 7, the rolling elements of the rolling element rows can 130 and 140 They may also be trained differently.

[0046] Examples of implementation can include rolling bearings. 100 and 400 provide, for example, a bevel pinion shaft 200 bearing components of a vehicle powertrain. Similar to the cup-shaped designs of the outer ring bearing arrangement described above. 110As shown, these bearing arrangements can, at least on one side, partially feature bearing rings with raceways made from a thin material such as sheet steel by forming, e.g., deep drawing. In other words, such a cup-shaped or cup-like form can be manufactured cost-effectively and, in exemplary embodiments, can be used as an outer ring bearing arrangement. 110 serve. In further embodiments, the rolling bearing can 500 for example, a bevel pinion shaft 200 A common outer ring bearing arrangement in a vehicle powertrain, as explained above, is also used. 110 for the storage arrangement 100 and 400 include.

This can offer advantages in load distribution. In other embodiments, an X-arrangement is of course also conceivable.

Fig. Figure 9 shows a cup-shaped outer bearing ring, which is defined by the bottom of the cup, which corresponds to the short leg of the L-shaped structure. 162 in the Fig. 9 corresponds to the running surface for the row of rolling elements. 130 This creates a thrust bearing in the present embodiment. The second row of rolling elements is formed by the tapered roller row. 140 formed and, in this embodiment, represents a radial bearing. The bearing arrangement 400 In this embodiment, it is also designed as an axial bearing, which carries loads in the opposite (axial) direction compared to the axial bearing row. 130 records.

For both cage components 170 and 180 However, in exemplary embodiments, a guide groove can be incorporated into one of the bearing rings. 110 or 120 be provided for. The exemplary embodiment of the Fig. Figure 2 shows a storage arrangement. 100 , which at least have a bearing cage 170 or 180 for guiding the first or second row of rolling elements 130 and 140The bearing cage features. 170 or 180 further includes a guiding means, for example in the form of a groove or a nose, which is connected to the bearing outer ring arrangement 110 or the inner ring bearing arrangement 120 for guiding the bearing cage 170 or 180 relative to the outer bearing ring arrangement 120 or the inner ring bearing arrangement 110 interacts. Similarly, the inner ring bearing arrangement can be configured. 120 or the outer bearing ring arrangement 110 have a corresponding groove into which a corresponding nose or extension of a bearing cage can be inserted. 170 or 180 can intervene, in order to then be guided by the bearing cage.
