Description

[0001] The invention relates to a bearing arrangement, in particular for supporting a transmission shaft, comprising a bearing with a bearing ring which is received on a cylindrical surface of a component located radially adjacent to the bearing ring, wherein the bearing ring is secured to the component against relative rotation in the circumferential direction by means of a locking element arranged radially between the bearing ring and the component, in that the locking element is located, firstly, in a groove which is circumferentially limited on both sides by the component, and secondly, engages in a recess which is circumferentially limited on both sides in the bearing ring. The invention further relates to a transmission with at least one of the aforementioned bearing arrangements.

[0002] In bearing arrangements, radial play in a bearing ring can lead to micro-movements of the ring due to vibrations. This can result not only in noise problems but also in increased wear of the bearing ring and the component that holds it. To prevent this, bearing rings are sometimes secured against rotation. In the simplest case, this anti-rotation measure is implemented using a locking element, which is placed radially between the bearing ring and the component that holds it.

[0003] German patent DE 10 2020 207 053 A1 discloses a bearing arrangement in which a rotor shaft is rotatably mounted in a housing via a rolling bearing. The rolling bearing is designed as a floating bearing, with an inner ring of the bearing fixed to rotation on a bearing seat of the rotor shaft, while an outer ring of the rolling bearing is received in a radially surrounding bearing bushing, which in turn is placed in a receptacle of the housing. The outer ring of the rolling bearing can move axially relative to the bearing bushing, and is supported against a bearing seat shoulder on the housing by a Belleville spring. The outer ring is further secured against relative rotation by a cylindrical locking element on the bearing bushing.The locking element is positioned radially between the outer ring and the bearing bushing by having axially extending grooves in both the outer ring and the bearing bushing, which together form a space for the radially interposed receiving of the locking element. The corresponding groove in the outer ring of the rolling bearing extends over the entire axial extent of the outer ring, i.e., continuously.

[0004] Furthermore, a bearing arrangement is known from JP 2008 082 486 A in which an undesired movement of a bearing outer ring is prevented by means of a dowel pin which engages on the one hand in a groove in the bearing outer ring and on the other hand in a housing part receiving the bearing outer ring.

[0005] Based on the prior art described above, the object of the present invention is to provide a bearing arrangement in which a reliable anti-rotation device is implemented for a bearing ring in a component that receives the bearing ring, while this anti-rotation device should result in the lowest possible weakening of the bearing ring. Furthermore, this bearing arrangement should be particularly feasible for a bearing designed as a floating bearing.

[0006] This problem is solved starting from the preamble of claims 1 and 4 in conjunction with their characterizing features. The subsequent dependent claims each describe advantageous embodiments of the invention. A transmission in which at least one bearing arrangement according to the invention is implemented is further the subject of claim 14.

[0007] According to the invention, a bearing arrangement comprises a bearing with a bearing ring which is received on a cylindrical surface of a component located radially adjacent to the bearing ring. The bearing ring is secured to the component against relative rotation in the circumferential direction by a locking element arranged radially between the bearing ring and the component, in that the locking element is radially located, on the one hand, in a groove which is circumferentially limited on both sides by the component, and on the other hand, engages in a recess which is circumferentially limited on both sides in the bearing ring.

[0008] In the bearing arrangement according to the invention, a bearing ring is provided, which is part of a bearing. The bearing is preferably designed for relatively rotatable mounting between a component and the component receiving the bearing ring, and is preferably a floating bearing. Furthermore, the bearing is particularly designed as a radial bearing, through which, in the case of relatively rotatable mounting, at least substantially only radial forces are transmitted between the component and the component. The bearing is particularly designed as a rolling bearing, which may preferably be a spherical roller bearing. Alternatively, the bearing can in principle also be another type of rolling bearing or a plain bearing.In addition to the bearing ring mounted on the component, the bearing also has another bearing ring, which is positioned radially outside or inside to the bearing ring mounted on the component and is arranged on the side of the component.

[0009] The bearing ring is mounted on a cylindrical surface of the radially adjacent component, the cylindrical surface being radially oriented towards the component and defined by the circumference of the bearing ring. In particular, radial contact between the bearing ring and the adjacent component is established at least on a portion of the cylindrical surface. For the purposes of this invention, "axial" means an orientation parallel to an axis of rotation about which rotatable support is provided by the bearing containing the bearing ring. "Radial," on the other hand, refers to an orientation in the diameter direction with the axis of rotation as its center point. "Circular direction" means a direction along the circumference of the respective component, in particular the component or the bearing ring.

[0010] To prevent relative rotation of the bearing ring to the component, the bearing arrangement according to the invention incorporates a locking element positioned radially between the bearing ring and the component. This locking element secures the bearing ring to the component in the circumferential direction by establishing a positive-locking connection in the circumferential direction on both sides, thus positively locking the bearing ring to the component in the circumferential direction. To achieve this, the locking element rests radially in a groove formed on the component side, which is bounded on both sides in the circumferential direction of the component. Furthermore, the locking element engages in a recess formed on the bearing ring side, which is also formed in the bearing ring and bounded in both directions in the circumferential direction of the bearing ring.Because both the groove and the recess are bounded on both sides in the circumferential direction of the component or bearing ring, and the radially interposed locking element lies in the groove on one side and engages in the recess on the other, the locking element indirectly prevents the relative rotation of the bearing ring to the component by means of a positive locking mechanism. Particularly preferably, the locking element is equipped with a rectangular cross-section, at least in the areas where it lies in the groove and engages in the recess, thereby ensuring a particularly reliable positive locking mechanism in the circumferential direction.

[0011] The groove formed on the component is preferably limited on both sides in the circumferential direction of the component by being axially extending and having a defined radial depth on one side of the component that faces radially towards the bearing ring. In particular, the groove is designed with a constant radial groove depth. Alternatively, but preferably additionally, the recess on the side of the bearing ring is preferably limited on both sides in the circumferential direction of the bearing ring by being formed as a radial depression in the outer surface of the bearing ring and having a defined axial extent within the bearing ring.

[0012] The invention further comprises the technical teaching that the recess extends axially only over a portion of the bearing ring. Furthermore, the locking element is axially coupled to the bearing ring by limiting movements of the locking element relative to the bearing ring in both axial directions via axially opposite contact surfaces of the bearing ring. In other words, the recess formed in the bearing ring extends only over a portion of its axial extent. Moreover, a coupling in both axial directions exists between the locking element and the bearing ring by defining contact surfaces on the bearing ring that are axially opposite to each other and each of which limits one axial movement of the locking element relative to the bearing ring, by causing the locking element to bear axially against the respective contact surface during each axial movement.

[0013] This type of bearing arrangement has the advantage that, firstly, because the recess only extends over a portion of the bearing ring, the bearing ring is only minimally affected, thus minimizing any weakening of the bearing ring, particularly in the load zone. Secondly, the positioning of the locking element in the groove on the component side and its engagement in the recess on the bearing ring side ensures reliable anti-rotation of the bearing ring relative to the component.

[0014] Furthermore, the axial coupling of the locking element to the bearing ring ensures reliable axial retention of the locking element on the bearing ring. This is particularly advantageous when the bearing is designed as a floating bearing and the bearing ring is intended to move axially relative to the component. This ensures that the locking element is always engaged in the recess on the bearing ring, thus guaranteeing a positive-locking connection between the bearing ring and the component in the circumferential direction. If the bearing ring is axially movable relative to the component, the component must also allow axial movement of the locking element relative to the component.This is particularly preferably achieved by the fact that the groove in which the locking element lies on the side of the component is designed to run axially and the locking element can thus move axially in the groove with the component during the movement of the bearing ring.

[0015] Essential to the invention is that the locking element is axially coupled to the bearing ring and thus moves axially with it. Slight axial relative movements of the locking element to the bearing ring are permitted, particularly in the sense of a clearance fit. The axial coupling ensures that the locking element remains in an axial position relative to the bearing ring in which it establishes the coupling of the bearing ring to the component in the circumferential direction. The contact surfaces provided on the bearing ring are axially opposite to each other, so that one contact surface limits axial movement of the locking element towards the bearing ring in one axial direction, and the other contact surface limits axial movement of the locking element towards the bearing ring in the other axial direction.

[0016] According to one embodiment of the invention, at least one of the contact surfaces is formed by an axially oriented end face with which the bearing ring is bounded at each axial end. The locking element has a radially extending section which is provided for axial contact of the locking element with each end face of the bearing ring.

[0017] In a further development of this embodiment, one contact surface at one of the axial ends of the bearing ring is formed by the end face defining this end. The locking element, with its associated radially extending section, can be axially pressed against this end face. The other contact surface is formed by an axially oriented wall that defines the recess and against which the locking element can be axially pressed when inserted into the recess. Advantageously, this allows for a simple axial coupling of the locking element with the bearing ring, as axial movements of the locking element relative to the bearing ring are limited in one axial direction by contact of the radially extending section with the end face and in the other axial direction by contact with the axially oriented wall of the recess.The recess, in conjunction with the locking element, performs the dual function of coupling the locking element to the bearing ring in the circumferential direction and limiting movement of the locking element relative to the bearing ring in an axial direction. Furthermore, this ensures that the locking element does not protrude axially, or only minimally, from the bearing ring on one axial side.

[0018] According to an alternative embodiment of the aforementioned design, both contact surfaces are formed by the end faces defining the axial ends of the bearing ring. The locking element has two radially extending sections with which it axially engages the bearing ring, each section being designed for axial contact of the locking element against one of the end faces. By axially engaging the bearing ring with the locking element, the axial coupling of the locking element to the bearing ring can be achieved in a reliable and simple manner.

[0019] An alternative embodiment of the invention is that the contact surfaces are formed by axially facing side walls of a groove, which is circumferentially provided in the outer surface of the bearing ring. The locking element has a radially projecting rib with which it engages radially in the circumferential groove. This allows for a particularly compact axial coupling of the locking element with the bearing ring. The locking element then does not protrude beyond the end faces of the bearing ring. Accordingly, the bearing arrangement according to the invention can be implemented in an axially compact installation space. The circumferential groove is preferably configured in an intermediate region between the axial ends of the bearing ring, and in particular, it is provided in an axial central region of the bearing ring.Particularly preferably, the circumferential groove is a supply groove through which lubricant and / or coolant can be radially supplied to the bearing, wherein the bearing ring is further preferably radially perforated with several passages that open into the circumferential groove and thus enable the lubricant and / or coolant supplied to the circumferential groove to be conveyed radially between the bearing rings of the bearing.

[0020] In a further development of the aforementioned embodiment, the web is designed to correspond to a cross-section of the circumferential groove. For the purposes of the invention, "corresponding" means that a cross-section of the web of the locking element essentially forms the counterpart to a cross-section of the circumferential groove. This ensures a particularly reliable axial coupling of the locking element with the bearing ring in both axial directions.

[0021] Alternatively or additionally, the web is provided with at least one opening through which the web of the locking element is penetrated in the circumferential direction of the bearing ring. This ensures that, when the circumferential groove is designed as a supply groove, the transport of lubricant and / or coolant via the circumferential groove is not impaired by the arranged locking element, but rather that the lubricant and / or coolant can flow through the locking element in the circumferential direction of the bearing ring via the at least one opening.

[0022] According to a further embodiment of the invention, the recess is formed in the outer surface of the bearing ring in the region of an axial end. Preferably, the recess has a rectangular cross-section. In a further embodiment, the recess extends linearly in the axial direction from an end face defining an axial end of the bearing ring onto the outer surface of the bearing ring. This allows the recess to be limited on both sides in the circumferential direction, and the recess can be designed such that as little material as possible needs to be removed from the bearing ring for its formation. For this purpose, the recess then extends axially over the smallest possible portion of the bearing ring. Instead of extending linearly onto the outer surface of the bearing ring, the recess can also extend non-linearly, for example, in a convex or concave shape.

[0023] When the aforementioned further development is combined with the variant of the invention in which the locking element axially surrounds the bearing ring, a base surface connecting the end face with the cylindrical surface extends at a distance from the locking element engaging in the recess. This has the advantage that, due to the lack of contact with the locking element in the axial direction, the linear course of the recess cannot cause the locking element to move radially out of the recess.

[0024] According to a further embodiment of the invention, the locking element rests radially on the bearing ring, at least predominantly, on a bearing surface formed by a portion of the bearing ring's outer surface. Thus, the bearing surface on which the locking element rests radially on the bearing ring is formed, at least substantially, by a portion of the bearing ring's outer surface. In this respect, the outer surface of the bearing ring is at least predominantly unaffected in the area where the locking element rests. Preferably, the bearing surface is interrupted only by the recess and, optionally, by the circumferential groove.

[0025] In a further embodiment of the invention, the locking element rests against the axially opposite contact surfaces of the bearing ring. This ensures that the locking element is reliably secured axially to the bearing ring. The contact can be achieved with a clearance fit, so that, due to tolerances, an axial gap may exist between the locking element and the respective contact surface.

[0026] In a further development of the invention, the bearing ring is axially movable relative to the component, wherein the groove formed on the component is designed as an axially continuous groove. Thus, the axial movement of the locking element with the bearing ring, and therefore also its axial movement relative to the component, is enabled by designing the groove in which the locking element sits as an axially continuous groove on the component.

[0027] In a further embodiment of the invention, the bearing ring is an outer ring which is received at its outer surface in a bore of the radially surrounding component. In a further development of this embodiment, the component is a housing or a bearing bushing which is received in a housing and secured against rotation relative to the housing. Alternatively, the bearing ring can also be an inner ring of the bearing, in which case the radially adjacent component receiving the bearing ring is preferably a shaft or an axle.

[0028] The invention further relates to a gearbox which has at least one bearing arrangement according to one or more of the variants described above. Preferably, a respective gearbox shaft is rotatably mounted via the bearing arrangement, wherein the bearing provided in the bearing arrangement is in particular a floating bearing.

[0029] Advantageous embodiments of the invention, which are explained below, are illustrated in the drawings. They show: Fig. 1 a sectional view of an area of ​​a bearing point of a gearbox; Fig. 2 a sectional view of a storage arrangement of the storage location Fig. 1, according to one embodiment of the invention; Fig. 3 a view of one aspect of the storage arrangement Fig. 2; Fig. 4 a view of another aspect of the storage arrangement Fig. 2; Fig. 5 a sectional view of a storage arrangement of the storage location Fig. 1, according to a further embodiment of the invention; and Fig. 6 a sectional view of a storage arrangement of the storage location Fig. 1, according to a further embodiment of the invention.

[0030] Out of Fig. Figure 1 shows a cross-sectional view of a bearing point 1 of a gearbox 2, in which a gearbox shaft 3 of the gearbox 1 is rotatably mounted in a housing 4 of the gearbox 2 via the bearing point 1. For this purpose, the bearing point 1 comprises a bearing in the form of a rolling bearing 5, specifically designed as a spherical roller bearing, with a bearing ring 6 in the form of an outer ring and a bearing ring 7 in the form of an inner ring. Radially between the bearing rings 6 and 7 are rolling elements 8, arranged in two rows and guided in a common cage 9, which can roll on raceways of the bearing rings 6 and 7. The rolling bearing 5 is designed as a floating bearing for the rotatable mounting of the gearbox shaft 3.

[0031] While the bearing ring 7 is fixed to the transmission shaft 3, the bearing ring 6 is positioned in a bearing bushing 10. For this purpose, the bearing bushing 10 has a through bore 11 in which the bearing ring 6 is received on a cylindrical surface 12 in the form of an outer cylindrical surface of the bearing ring 6. As shown in Fig. As can be seen in Figure 1, a groove 13 is formed in the outer surface 12 of the bearing ring 6, extending circumferentially around the bearing ring 6. Several radially extending passages 14 open into the groove 13, each connecting the groove 13 to the radial area between the bearing rings 6 and 7 in which the rolling elements 8 run. Lubricant, in particular oil, is supplied to the groove 13 from the housing side, and the lubricant can then flow from the groove 13 into the passages 14 and subsequently radially between the bearing rings 6 and 7 into the area of ​​the rolling elements 8, thus lubricating and cooling the rolling bearing 5.

[0032] The bearing bushing 10 is received in a receiving bore 15 of a housing part 16 of the housing 4, whereby the bearing bushing 10 is secured against relative rotation in the housing part 16. For this purpose, a pin 17 is inserted into the housing part 16, which engages at its end in a recess 18. This recess 18 is defined on an outer circumference of the bearing bushing 10.

[0033] Due to the arrangement of the rolling bearing 5 as a floating bearing, the bearing ring 6 should be able to move axially relative to the bearing bushing 10 to accommodate different thermal expansions and compensate for manufacturing tolerances. Relative rotation of the bearing ring 6 relative to the bearing bushing 10, for example due to vibrations, should be prevented in order to avoid noise generation and wear of the bearing bushing 10 and the bearing ring 6, particularly those caused by micro-movements. To prevent relative rotation, measures have been implemented at bearing point 1 within a bearing arrangement that corresponds to one of the variants described below.

[0034] This is how it goes Fig. Figure 2 shows a sectional view of a bearing arrangement 19, which is implemented according to an embodiment of the invention. In this bearing arrangement 19, a locking element 20 is radially accommodated between the bearing ring 6 and the bearing bushing 10, wherein the locking element 20 positively couples the bearing ring 6 to the bearing bushing 10 in the circumferential direction. For this purpose, the locking element 20 lies in a groove 21 on the side of the bearing bushing 10, which is located in particular in Fig. Figure 3 shows a close-up view of the bearing bushing 10. The groove 21 extends axially into an inner circumference 22, which is defined by the through-bore 11 of the bearing bushing 10. The groove 21 is axially continuous, meaning it runs completely through the bearing bushing 10. Due to its axial orientation, the groove 21 is also bounded on both sides in the circumferential direction.

[0035] On the side of the bearing ring 6, the locking element 20 rests essentially radially on a bearing surface 23, which is formed by a portion of the cylindrical surface 12 of the bearing ring 6. Furthermore, a recess 24 is formed at one point in the circumferential direction of the bearing ring 6, which is particularly Fig. As can be seen in Figure 4. The recess 24 is bounded on both sides in the circumferential direction of the bearing ring 6 and extends linearly in the axial direction from an end face 25 of the bearing ring 6 onto the cylindrical surface 12. In other embodiments, the recess 24 can also extend non-linearly onto the cylindrical surface 12. The end face 25 defines an axial end 26 of the bearing ring 6, which lies opposite an axial end 27 of the bearing ring 6, defined by an end face 28 located opposite the end face 25.

[0036] Apart from resting on the bearing surface 23, the locking element 20 engages with a projecting section 29 in the recess 24 of the bearing ring 6, the section 29 being wedge-shaped and essentially forming a counterpart to the recess 24. Due to this engagement in the recess 24, which is bounded on both sides in the circumferential direction, and the receiving of the locking element 20 in the groove 21, which is also bounded on both sides in the circumferential direction, a positive-locking connection of the bearing ring 6 to the bearing bushing 10 is achieved via the locking element 20 in the circumferential direction, thereby preventing the bearing ring 6 from rotating.

[0037] As a special feature, the locking element 20 is now axially coupled to the bearing ring 6, so that when the bearing ring 6 moves axially towards the bearing bushing 10, the locking element 20 moves axially with the bearing ring 6. For this purpose, the locking element 20 is equipped with a radially extending section 30, with which the locking element 20 rests against the end face 28 of the bearing ring 6. Furthermore, the locking element 20 also rests with section 29 against a wall in the form of a base surface 31, over which the end face 25 of the bearing ring 6 transitions via the recess 24 into the outer surface 23. The base surface 31 and the end face 28 are oriented axially opposite to each other, so that axial movements of the resting locking element 20 relative to the bearing ring 6 are positively prevented in both axial directions.Since the groove 21 is designed to be continuous on the side of the bearing bushing 10, the locking element 20 can easily move axially in the groove 21 during the joint axial movement with the bearing ring 6.

[0038] The anti-rotation feature of the bearing ring 6 is achieved with only a slight weakening of the bearing ring 6, since the anti-rotation feature and the axial fixation of the locking element 20 to the bearing ring 6 require only the recess 24, which extends over only a very small axial portion of the bearing ring 6 and constitutes only a small part of the bearing ring 6 overall. In particular, the axial fixation of the locking element 20 is achieved through the appropriate design of the locking element 20.

[0039] Fig. Figure 5 shows a sectional view of a bearing arrangement 32 according to a further embodiment of the invention, which is an alternative to the bearing arrangement 19 made from the Fig. 2, Fig. 3 to Fig. 4 at storage site 1 in Fig. 1 can be applied. This bearing arrangement 32 essentially corresponds to the previous variant according to the Fig. 2, Fig. 3 to Fig. 4, with the difference that a differently designed locking element 33 is now arranged radially between the bearing bushing 10 and the bearing ring 6. This locking element 33 is axially coupled to the bearing ring 6 by the fact that, in addition to the contact of section 30 with the end face 28 of the bearing ring 6, the locking element 33 also contacts the end face 25 opposite the end face 28 with a section 34. Consequently, the locking element 33 axially surrounds the bearing ring 6.

[0040] Section 34 directly links to Section 35 of the locking element 33, with Section 35 being similar to Section 29 of the locking element 20 from the Fig. 2, Fig. 3 to Fig. Section 35 is wedge-shaped. However, although contact is established on both sides of the recess 24 in the circumferential direction via section 35, no contact occurs with the bottom surface 31 of the recess 24. This ensures that the linear course of the recess 24, in conjunction with the wedge-shaped design of section 35, does not lead to the locking element 33 being radially pushed out of the recess 24 during axial movement with the bearing ring 6. Otherwise, the design option corresponds to... Fig. 5 of the variant according to the Fig. 2, Fig. 3 to Fig. 4, so that reference is made to what is described here.

[0041] Finally, it also goes out Fig. Figure 6 shows a sectional view of a bearing arrangement 36, which corresponds to a further embodiment of the invention and which is also an alternative to the bearing arrangement 19. Fig. 2, Fig. 3 to Fig. 4 at storage site 1 in Fig. 1. This embodiment largely corresponds to the previous variant according to Fig. 5 and differs from the bearing arrangement 32 in that a differently designed locking element 37 is used to prevent the bearing ring 6 from rotating on the bearing bushing 10.

[0042] Thus, this locking element 37 does not have any axially end-facing sections for axial coupling of the locking element 37 with the bearing ring 6, but the axial coupling is, in the case of the embodiment according to Fig. The locking element 37 is attached via a radially projecting web 38, which extends radially into the circumferential groove 13 of the bearing ring 6 and is designed correspondingly to the groove 13. The locking element 37 is in contact with side walls 39 and 40 on the web 38, whereby the locking element 37 is axially engaged with axial movements of the bearing ring 6.

[0043] The locking element 37 is also provided with an opening 41, which, as a circular bore, penetrates the web 38 in the circumferential direction of the bearing ring 6. The lubricant, guided via the groove 13, can easily flow through the locking element 37 via this opening 41. Otherwise, the embodiment corresponds to... Fig. 6 of the previous variant Fig. 5, so that reference is made to what is described here.

[0044] Using the embodiments according to the invention, a reliable anti-rotation device can be provided for a bearing ring of a floating bearing with the least possible weakening of the bearing ring.
