Description

The invention relates to a bearing ring arrangement, in particular a rolling bearing inner ring arrangement, and a bearing with such a bearing ring arrangement.

Bearing ring arrangements are already known from the prior art, these mostly serve to be arranged in a rolling bearing. In the case of compact bearings in particular, the bearing ring arrangement is formed by two bearing ring segments, which are usually pushed onto the shaft to be supported separately in order to be fixed there with a shaft nut or a similar clamping device. However, it has been found that the separability of these two-part bearing ring arrangements causes a high outlay on assembly.

It is therefore an object of the present invention to provide an easy-to-assemble bearing ring.

This object is achieved with a bearing ring according to claim 1 and with a bearing according to claim 10. Further advantageous embodiments and features result from the subclaims, the description and the figures.

According to the invention, a bearing ring arrangement, in particular bearing inner ring arrangement, which extends in an axial direction, comprises a first bearing element and a second bearing element, the first bearing element and the second bearing element each having an inner support surface, the first bearing element and the second bearing element each having an outer support surface , wherein the first bearing element has a connection section, the connection section forms at least one connection structure, the second bearing element has a connection section, the connection section forms at least one connection structure, the connection section and the connection section in an assembled state in such a manner indirectly and / or directly to one another are connected or connectable such that a separation in the axial direction of the first bearing element from the second bearing element is positive, in particular by means of the at least one connection structure and the at least one connection structure is prevented. The bearing ring arrangement according to the invention can form an inner or an outer ring of a bearing arrangement. The bearing arrangement serves, in an installed state, to support a first component relative to a second component, in particular in such a way that these two components can rotate relative to one another and / or that forces between these two elements can be transmitted via the bearing. The first and the second component to be supported can in particular be a hub and a shaft / axis. The bearing ring arrangement extends, in particular in the assembled state, in a longitudinal direction, this longitudinal direction can in particular be the direction in which the bearing ring arrangement has its largest dimension. Alternatively or additionally, the longitudinal direction can also be the direction by which the first component can rotate relative to the second component. The bearing ring arrangement comprises a first bearing element and a second bearing element, each of these two separate components having an inner support surface and an outer support surface. Advantageously, the first bearing element and the second bearing element are each made in one piece in order to achieve a particularly high mechanical strength of the bearing elements. The inner support surface is designed, in particular when the bearing ring arrangement forms an inner bearing ring, as an indirect or direct support surface with respect to the inner component to be supported, the outer support surface making direct or indirect contact with an opposite outer bearing ring. In particular, if the bearing ring arrangement is a roller bearing inner ring arrangement, the outer support surface of the first bearing element and / or the outer support surface of the second bearing element is formed by the surface which serves to directly absorb forces from the roller bodies and / or towards the roller bodies transfer. If the bearing ring arrangement is designed as a bearing outer ring, however, the outer support surface is used for support against the outer component and the inner support surface accordingly for indirect or direct support against the corresponding bearing inner ring. The first bearing element has a connection section which forms a connection structure. This connection structure can be designed, for example, as a projection or recess. The second bearing element, however, has a connection section, which in turn forms a connection structure. This connection structure can also be formed, for example, by a projection or recess. In an assembled state, the connection section and the connection section are connected or connectable to one another directly or indirectly in such a way that separation in the axial direction of the first bearing element from the second bearing element is positively prevented. Among other things, separation is positively prevented if the connecting section and the connecting section can come into direct or indirect contact with one another in such a way that the two bearing elements cannot or should not be spaced as far apart from one another in an assembled state in the (+/-) axial direction can be separated without part of the first bearing element and / or a connecting element and / or the second bearing element must be plastically deformed or destroyed. However, this does not mean that the two bearing elements cannot have any play in relation to one another in an assembled state. In other words, this can mean that the connection structure and the connection structure form a positive separation protection. In particular, this form-fitting separation assurance takes place in that the at least one connection structure makes direct and / or direct contact with at least one connection structure or this possible contact positively prevents the separation. By means of this form-fitting separation securing of the first bearing element to the second bearing element, the bearing ring arrangement can be assembled in a simple manner, because during assembly only one arrangement - connected by the separation securing means - has to be handled.

The bearing ring arrangement is advantageously a commercial vehicle wheel bearing ring arrangement. The handling of wheel bearing rings during assembly is a major problem, particularly in the case of commercial vehicles. This problem can be eliminated or at least minimized in a simple manner by means of the positive locking device described, so that costs can be saved in the assembly of the commercial vehicle wheel bearing ring arrangement.

For a particularly secure form-fitting separation assurance, it is advantageous if the connection section forms a plurality of connection structures and / or the connection section forms a plurality of connection structures. In order to achieve the most uniform possible mechanical loading of the connection section and the connection section, it is expedient if the connection structures and / or the connection structures are arranged uniformly distributed around the axial direction. Advantageously, the connection structures are each arranged opposite a connection structure in the axial direction.

The connecting section preferably delimits the first bearing element in the axial direction, in particular by an end face, and / or the connecting section delimits the second bearing element in the axial direction, in particular by an end face. In other words, this can mean that the connection section forms a distal end of the first bearing element, in particular through an end face of the connection section. This distal end is in particular the distal end of the first bearing element which, viewed in the axial direction, faces the center of gravity of the second bearing element when the bearing ring arrangement is in an assembled state. The assembled state of the bearing ring arrangement is in particular the state in which the bearing ring is arranged in its final position relative to the first and / or the second component to be supported. Alternatively or additionally, the assembled state can also be the state in which the bearing ring arrangement is preloaded in the axial direction. The end face is in particular a face which has an angle of 90 ° +/- 5 ° to the axial direction, because this enables the end face to be produced in a simple manner, so that a favorable first bearing element results. Similar to the connection section of the first bearing element, the connecting section of the second element can also form a distal end of the second bearing element, this distal end being in particular the end which faces the first bearing element in the assembled state. This distal end or the delimitation of the second bearing element is advantageously formed by an end face of the second bearing element, which also preferably has an angle of 90 ° +/- 5 ° to the axial direction. In an assembled state, one of these two end faces is advantageously designed to make contact, in particular over a large area, with a corresponding counter surface of the other bearing element. The indirect and / or direct contact of the end face and the counter face serves to transmit the axial prestressing forces, in particular exclusively, between the first bearing element and the second bearing element. As a result, in particular the connection structures and / or the connection structures can be mechanically relieved, since they are not or only slightly mechanically loaded by the pretension in a pretensioned state of the bearing ring arrangement. These structures can thus be made correspondingly thinner, so that costs and weight can be saved. The counter surface can be designed or arranged such that it borders or delimits the connection section or the connection section distally opposite to the respective end surface. In other words, this can mean that the connecting section and / or the connecting section can be bordered in the axial direction on the one hand by an end face and on the other hand by a counter face.

The inner support surfaces or the outer support surfaces are advantageously designed as rolling surfaces for one or a plurality of rolling elements. In other words, this can mean that the bearing ring arrangement is a bearing ring arrangement for a rolling bearing, in particular for a compact rolling bearing. This makes it possible to achieve a roller bearing that is particularly easy to assemble. Compact roller bearings are roller bearings which have at least two rows of roller bearing bodies in the axial direction, these being apart are spaced. These rows of rolling elements can in particular be designed as an X or O arrangement, so that the inner support surfaces or the outer support surfaces (depending on whether it is an inner bearing ring arrangement or an outer bearing ring arrangement) can be configured obliquely to the axial direction. This makes it possible for the bearing ring arrangement according to the invention to ensure a particularly stable and secure support of the two components to be supported relative to one another.

Advantageously, the bearing ring arrangement comprises at least one connecting element, preferably a plurality of connecting elements, the connecting section and the connecting section being connected or connectable with at least one connecting element, preferably with a large number of connecting elements, the connecting element being form-fitting in the connecting structure and form-fitting in the connecting structure engages in such a way that separation of the first bearing element from the second bearing element in the axial direction is prevented. As a result, the assembly of the bearing ring arrangement can be simplified. In addition, the number of contact surfaces present in the bearing ring arrangement is increased by using the connecting element or elements. This increase in the number of contact surfaces causes an increase in the existing contact damping, so that this can improve the vibration behavior of the bearing ring arrangement. The connection section particularly preferably has a corresponding connection structure for each connection element and the connection section in each case has a corresponding connection structure. In other words, the connection section for each connection element has its own connection structure corresponding to the connection element, and the connection section likewise each has a connection structure for each connection element. As a result, the assembly of the bearing ring arrangement can be further simplified and its mechanical resilience can be increased.

In a preferred embodiment, the connection structure has an undercut in which the at least one connection element engages, the connection structure having an undercut in which the at least one connection element engages. In this way, a particularly simple and space-saving, form-fitting fixing of the first bearing element to the second bearing element can be achieved. This undercut is preferably designed such that the connection structure and the connection structure each engage behind the connection element in the axial direction. For example, the undercut of the connection structure can be V-shaped, in particular V-shaped in the axial direction. It is particularly preferred here if the connection structure and the connection structure are configured identically, so that the connection element can be mounted in at least two different orientations.

In an advantageous embodiment, the connecting element is designed as a sealing element. This double function of the connecting element can, for example, save an additional sealing element, so that costs can be saved. In order to achieve a high sealing function, it is preferred if the connecting element is formed at least in regions, preferably completely, from a rubber and / or from a plastic.

In an assembled state, the connection section and the connection section are preferably designed to be able to contact and / or contact one another directly, this direct contact preventing separation of the first bearing element from the second bearing element in the axial direction. This allows a particularly compact and thus a particularly compact bearing ring arrangement to be achieved. In addition, this configuration also makes it possible to omit the connecting elements. In other words, the bearing ring can thus be designed without connecting elements. The separation in the axial direction is prevented in particular by the fact that the connection structure can be contacted with the connection structure. A separation is prevented, inter alia, when the first bearing element is not completely freely movable in the axial direction (+/-) relative to the second bearing element, but rather there is only limited freedom of movement of the two bearing elements relative to one another. In other words, this can mean that the two bearing elements may have a certain amount of play in the axial direction, in particular, however, not more than 8 mm.

In an assembled state, the connection section and the connection section preferably overlap in the axial direction. In this way, a particularly compact bearing ring arrangement can be achieved, so that installation space can be saved. In this context, “overlapping” can be understood to mean that at least parts of the connecting section and parts of the connecting section are present in a sectional plane whose normal is parallel to the axial direction. In other words, this can mean that there is at least one region of the bearing ring arrangement in the axial direction in which both parts of the connection section and parts of the connection section are present. In order to achieve a particularly compact bearing ring arrangement, it is advantageous if the ratio of the length of the overlapping area of the connection section and the connecting section in the axial direction to the total length of the bearing ring arrangement in the axial direction is in a range from 0.05 to 0.3. However, the ratio is particularly preferably in a range from 0.07 to 0.15, since this ensures that the separation can be secured particularly mechanically.

The connecting section preferably essentially surrounds the connecting section in a radial direction. As a result, the connection section acts as a kind of protective cover for the connection section, so that the connection section is mechanically protected by the connection section. In addition, this also prevents or minimizes the occurrence of contamination in the gap between the connecting section and the connecting section. The radial direction is the direction which points radially away from the axial direction. In this context, “essentially” can be understood to mean that the connecting section predominantly, in particular completely, surrounds the connecting section in a sectional plane, the normal of which is parallel to the axial direction. However, it is not absolutely necessary for the connecting section to surround the connecting section over the entire length in the axial direction. Advantageously, however, the connecting section also predominantly surrounds the connecting section in the axial direction, in particular at least 90%. This can further prevent or minimize the ingress of contaminants.

In an assembled state, the connection structure and the connection structure advantageously engage behind one another in the axial direction. In this way, a particularly safe axial positive separation prevention can be achieved. For example, the engagement can be achieved by a bayonet-type configuration of the connection section or the connection section. Alternatively, it can preferably be gripped behind by the connecting section being designed as a thread and the connecting section correspondingly as a complementary or corresponding thread. Such a thread can be, for example, a metric thread or a self-sealing thread. Alternatively, the connection structure and the connection structure can also be designed as complementary or corresponding polygons, so that the inner contour is designed to be complementary or corresponding to the outer contour of the other section. These polygons can be designed like a key-lock principle. In other words, these polygons - after a match - be rotated relative to one another, in particular about the axial direction, so as to achieve a grip behind.

The connection structure and the connection structure can expediently be guided past one another in the axial direction, in particular without deformation. In this way, a particularly simple assembly of the bearing ring arrangement can be achieved. For example, the first bearing element can be moved past one another when the first bearing element can be transferred from the state which is completely separated in the axial direction to another state in which the bearing ring arrangement is in a state, in particular an assembled state, in which part of the connection structure is closer to the center of gravity of the second bearing element in the axial direction than the connecting structure of the second bearing element. In this context, deformation-free can be understood to mean that the connection structure and / or the connection structure does not have to be deformed mechanically, in particular with regard to their outer or inner shape, in order to achieve a passing of the connection structure to the connection structure. For example, deformation-free passing can be achieved in that the connecting section is designed as a polygon or as a thread and the connecting section is correspondingly complementary and / or corresponding thereto. The receiving structure can advantageously be designed as an internal thread and the connecting structure as an external thread.

The connection structure and the connection structure are preferably designed to correspond to one another. “Corresponding” can mean in particular that the connection structure and the connection structure can be guided into one another, in particular in the axial direction, and that the respective outer or inner structure is adapted to the other structure. In other words, the connection structure and the connection structure can be designed to be complementary to one another. For example, the connection structure and the connection structure can be designed in a key-lock manner. This can happen in particular in that the receiving structure has an eccentric outer structure - similar to a cam - and the connecting section - has a corresponding eccentric inner contour. It is also conceivable that the receiving structures have several eccentrically outwardly projecting outer contours around the axial direction and the connecting section correspondingly has a corresponding inner contour. Due to the corresponding configuration of the connection structure to the connection structure, it can be achieved that a particularly simple assembly of the bearing ring arrangement is possible.

The connection section advantageously comprises a receiving structure, the receiving structure being designed to receive the connecting structure in an assembled state. This enables a particularly compact design of the bearing ring. The receiving structure can be configured, for example, as a recess or as a groove running radially around the axial direction. In this context, “receiving” is to be understood to mean that the receiving structure forms or represents a free space in which the connecting structure can be in an assembled state, in particular with play in the axial direction. This allows the connection structure to reach behind the connection structure in a simple manner.

In an advantageous embodiment, the receiving structure has a length in the axial direction, the connecting structure having a length in the axial direction, the length of the connecting structure in the axial direction being smaller than the length of the receiving structure in the axial direction. This results in a particularly compact bearing ring arrangement, because the connection structure is thus able to be completely accommodated in the receiving structure. In addition, in the case of an axially preloaded bearing, for example, this means that this axial preload (in the axial direction) does not have to be transmitted mechanically through the connection structure, so that the loads acting on the connection structures are reduced, so that the connection structure can be dimensioned to save weight , In particular, the ratio of the length of the connecting structure to the length of the receiving structure is in a range from 0.5 to 0.95, because this enables the receiving structure to be produced particularly easily. The ratio of the length of the connecting structure to the length of the receiving structure is preferably in a range from 0.6 to 0.9, since this enables a particularly compact receiving structure to be achieved, so that a space-saving bearing ring arrangement results. The ratio of the length of the connecting structure to the length of the receiving structure is particularly preferably in a range from 0.7 to 0.85, because the applicant has surprisingly found that this results in a particularly mechanically resilient bearing ring arrangement owing to the low notch effect.

The connecting section preferably comprises a free space structure, the free space structure being designed to receive the connection structure in an assembled state. The free space structure can have the same features and / or advantages as the receiving structure in relation to the connection structure, but it is not necessary that in addition to the free space structure, a receiving structure must also be present. In other words, the free space structure is designed as a functionally identical structure to the receiving structure. For example, the free space structure can be designed as a radially circumferential groove made in the connecting section. If a free space structure and a receiving structure are present, it is particularly preferred that the length of the free space structure in the axial direction is less than the length of the receiving structure in the axial direction, because this makes it possible, among other things, to avoid costly double fits.

The bearing ring arrangement expediently consists at least in regions, preferably completely, of steel, in particular roller bearing steel and / or spring steel. In this way, a particularly resilient bearing ring arrangement can be achieved.

Another aspect of the invention relates to a bearing, in particular a rolling bearing, comprising a bearing ring arrangement. This bearing ring arrangement can have the aforementioned features and advantages.

The bearing ring arrangement according to the invention 1 comprises a first bearing element 10 and a second bearing element 30 , each of these bearing elements having an inner support surface 2 which is with the axis 70 contacted. The inner support surfaces 2 serve forces from the first bearing element 10 or from the second bearing element 30 towards the radial direction R from the bearing ring arrangement 1 on the axis 70 transferred to.

The bearing ring arrangement 1 extends in the axial direction A , with the axis direction A is also the axis of rotation about which the axis is 70 can rotate. In addition to the inner support surfaces 2 the bearing ring arrangement also has outer support surfaces 4 , the first bearing element 10 and the second bearing element 30 one outer support surface each 4 form.

The bearing ring arrangement 1 which in the 1 is shown in an assembled state, is in the axial direction A through the shaft nut 72 opposite the axis 70 braced. These preload forces are between the first bearing element 10 and the second bearing element 30 thereby through the connection section 12 of the first bearing element 10 and the connecting section 32 of the second bearing element 30 transfer.

In the 2 is an exemplary embodiment of the connector section 12 and the connecting section 32 shown, which for a detailed view of the in the 1 Embodiment shown (in a circle) can fit. The connection section 12 forms a connection structure in the illustrated embodiment 14 in the form of an internal thread. The connection section is bordered 12 in one direction (in the axial direction A ) through the face 18 and in the other direction (in the axial direction A ) through the counter surface 19 ,

Adjacent to the connection structure 14 forms the connection section 12 an admission structure 16 from which the connection structure 34 receives. This connection structure 34 is formed in the embodiment shown by an external thread. In addition to the connection structure 34 has the connecting portion 32 a free space structure 36 on what the connection structure 14 of the connection section 12 receives. The connection section is bordered 32 (in the axial direction A ) through the counter surface 39 and through the face 38 ,

In the in 2 illustrated embodiment contacts the counter surface 39 the connecting section 32 directly with the face 18 of the connection section 12 , Due to this direct contact, it is in the axial direction A the prestressing of the bearing arrangement in a form-fitting manner between the first bearing element 10 and the second bearing element 30 transfer. The face 38 the second bearing element, however, has a game to the counter surface 19 of the first connection section 12 so that these two surfaces do not contact each other directly.

In the 3 is a further embodiment of the connection section 12 and the connecting section 32 shown which of the in the 2 shown embodiment can correspond. The connection structure 14 has a length L14 in the axial direction A , the reception structure 16 a length L16 in the axial direction A , the connection structure 34 a length L34 and the free space structure 36 a length L36 in the axial direction A on.

The ratio of the average diameter is preferred d _m the connection structure 14 to the maximum outside diameter D _A thereby in a range from 1.05 to 1.2, because the applicant has surprisingly found that a particularly resilient bearing ring arrangement can be achieved in this way.

In the 4 is a further embodiment of a bearing ring arrangement according to the invention 1 shown. In the illustrated embodiment, the separation of the first bearing element 10 to the second bearing element 30 form-fitting through the connecting element 50 prevented. The connecting element 50 is both at the connection section 12 as well as at the connecting section 32 arranged, the connecting element 50 has a click-type fastening mechanism through which the connecting element 50 form-fitting against a shift in the radial direction R (positive and negative) is secured.

In the 8th is a further embodiment of a bearing ring arrangement according to the invention 1 shown. In the bearing ring arrangement shown 1 is the connection structure 34 formed as a cam-like structure and the connection structure 14 as a corresponding cam-like structure. As from the 8th emerges is the connection structure 34 radially protruding in the upper area in a cam-like manner and not in the lower area. This cam-like projection of the connection structure 34 engages behind the complementary cam-shaped connection structure 14 , so that a separation of the first bearing element 10 to the second bearing element 30 in the axial direction A in the illustrated - assembled state - is not possible.
