    DETAILED DESCRIPTION

    [0033] FIG. 1 shows an embodiment of a bearing arrangement 10. The bearing arrangement 10 has a bearing receiver 100 with a receiver region 11. The receiver region 11 has two receivers 111, 112, namely a first receiver 111 and a second receiver 112. A base 12 is formed between the first receiver 111 and the second receiver 112. A through-hole 13 is configured in the base 12. A shaped body 20, 21 is inserted into each of the receivers 111, 112. In this regard, the bearing arrangement 10 has a first shaped body 20 and a second shaped body 21. The first shaped body 20 and the second shaped body 21 are arranged opposite one another in the receiver region 11. Each of the two shaped bodies 20, 21 has a bottom surface 201 on the front face. It can be seen that the base 12 for each of the shaped bodies 20, 21 forms an axial limit. In FIG. 1 the bottom surface 201 of the shaped bodies 20, 21 bears against the base 12.

    [0034] The shaped bodies 20, 21 have in each case a recess 23. The bearing core 31 is received in this recess 23. The recess 23 has a first portion 231 and a second portion 232. The internal diameter of the first portion 231 corresponds in terms of shape and size to the external diameter of the bearing core 31. The internal diameter of the second portion 232 is larger than the external diameter of the bearing core 31. Moreover, the first portion 231 is substantially cylindrical. The second portion 232 is conical at least in some portions.

    [0035] The bearing core 31 extends through both shaped bodies 20, 21 and is fixed in the example shown in FIG. 1 by two end plates 32. In this manner, pressure can be exerted on the shaped bodies in the axial direction, so that the shaped bodies 20, 21 are held so as to be pretensioned in the receiver region 11.

    [0036] In the exemplary embodiment shown in FIG. 1, the first and second receiver 111, 112 in each case have a first region 113, which directly adjoins the base 12, and a second region 114 which is arranged in the axial direction remote from the base 12. The first region 113 is configured to be cylindrical. The second region 114 is configured to be conical. At least the inner wall 115 of the cylindrically configured first region 113, in each case serves as a radial limit for the shaped bodies 20, 21. In this regard, the shaped bodies 20, 21 inserted into the receivers 111, 112 of the receiver region 11 encounter an axial or radial limit both on the base 12 and on the inner wall 115 of the respective receiver 111, 112. It can be seen that the first region 113 forms a radial cylindrical limit portion for the shaped body 20, 21.

    [0037] The variants of the bearing arrangement 10 shown in FIGS. 2, 3, 4, 5 and 6 also have in each case a bearing receiver 100 comprising a receiver region 11. The receiver region has in each case a first receiver 111 and a second receiver 112, wherein a base 12 is configured with a through-hole 13 between the first receiver 111 and the second receiver 112. A shaped body 20, 21 is also inserted in each of the receivers 111, 112, wherein each of the two shaped bodies 20, 21 has a bottom surface 201 on the front face. The base 12 forms an axial limit for each of the shaped bodies 20, 21.

    [0038] The shaped bodies 20, 21 in each case have a recess 23. The bearing core 31 is received in this recess 23. The recess 23 has a first portion 231 and a second portion 232. The internal diameter of the first portion 231 corresponds in terms of shape and size to the external diameter of the bearing core 31. The internal diameter of the second portion 232 is larger than the external diameter of the bearing core 31. Moreover, the first portion 231 is substantially cylindrical. The second portion 232 is conical at least in some portions. The inner wall 115 of the receivers 111, 112 serves in each case at least in some portions as a radial limit for the shaped bodies 20, 21. In this regard, the shaped bodies 20, 21 inserted into the receivers 111, 112 of the receiver region 11 encounter an axial or radial limit both on the base 12 and on the inner wall 115 of the respective receiver 111, 112.

    [0039] In the exemplary embodiment shown in FIGS. 3, 4 and 5, the receivers 111, 112 also have, as in the exemplary embodiment shown in FIG. 1, in each case a first region 113 which directly adjoins the base 12 and a second region 114 which is arranged remote from the base 12 in the axial direction. The first region 113 is configured to be cylindrical. The second region 114 is configured to be conical. At least the inner wall 115 of the cylindrically configured first region 113, serves in each case as a radial limit for the shaped bodies 20, 21. In this regard, the shaped bodies 20, 21 inserted into the receivers 111, 112 of the receiver region 11 encounter an axial or radial limit both on the base 12 and on the inner wall 115 of the respective receiver 111, 112. In all four examples (FIGS. 1, 3, 4 and 5) the internal diameter of the first region 113 is at least predominantly smaller than the internal diameter of the second region 114. The internal diameter of the conical part of the second region 114 becomes larger in the axial direction x facing away from the base.

    [0040] In the exemplary embodiment shown in FIG. 2, the receivers 111, 112 are configured to be cylindrical in each case and consist of a single continuous region. Here the inner face 115 also forms a radial limit for the shaped bodies 20, 21.

    [0041] In the exemplary embodiment shown in FIG. 5, the diameter of the second region 114 in a small region, namely at the point at which the first region 113 and the second region 114 adjoin one another, is smaller than the diameter of the first region 113. In this manner, an undercut 40 is formed. In the remaining part of the region 114, however, the diameter of the region 114 is larger than the diameter of the region 113, so that here the internal diameter of the first region is at least predominantly smaller that the internal diameter of the second region 114. The shaped bodies 20, 21 in each case have a latching ring 25. The latching ring 25 engages behind the undercut 40. In this manner, the undercut 40 and the latching ring 24 limit the movement of the respective shaped body 20, 21 in the axial direction x.

    [0042] In the exemplary embodiment shown in FIG. 6, the receivers 111, 112 have, as in the examples in FIGS. 1, 3, 4 and 5, in each case a first region 113 and a second region 114. The first region 113, which is configured as described above in the vicinity of the base 12, has a first cylindrical part and a conical portion which follows in the axial direction x and which adjoins the second region 114. The second region 114 is configured to be cylindrical. In this exemplary embodiment, the internal diameter of the second region 114 is smaller than the internal diameter of the first region 113. In this manner, an undercut 40 is configured between the first region 113 and the second region 114. Here the shaped bodies 20, 21 have in each case a latching ring 25 which together with the undercut 40 limits a movement of the respective shaped body 20, 21 in the axial direction x.

    [0043] In the exemplary embodiments shown in FIG. 2 and FIG. 6, the bearing receiver 100 also has in each case a front face 116 at both ends. The shaped bodies have in each case a support collar 24 with a support surface 241. The support surface 241 bears against the front face 116 of the bearing receiver 100. In this regard, the support collar 24 provides additional protection against the respective shaped body 20, 21 slipping further than intended into the receiver 111, 112.

    [0044] In the exemplary embodiment shown in FIG. 3, it can be seen that a fixing ring 50 is inserted in each case into the receivers 111, 112. The fixing ring 50 is arranged at the transition between the first region 113 and the second region 114. The shaped bodies 20, 21 have in each case a latching groove 27. The latching groove 27 positively encompasses the fixing ring 50. The fixing ring 50 acts as a narrowing of the receiver 111, 112 and thus as the above-described undercut 40.

    [0045] In the exemplary embodiment shown FIG. 4, radial bore holes 60 are configured in each case in the first region 113 of the receivers 111, 112, i.e. bore holes 60 which are oriented in the radial direction r. In the region of the bore holes 60, the diameter of the first region 113 is larger than the diameter of the adjoining part of the second region 114. In this regard, the bore holes 60 also act as an undercut 40. The shaped bodies 20, 21 have latching cams 26. The latching cams 26 engage in the bore holes 60 in the assembled state.

    [0046] The invention is not limited to one of the above-described embodiments but can be modified in many different ways.

    [0047] It is conceivable, for example, that the receivers 111, 112 are symmetrically configured. However, it is also possible that the receivers 111, 112 are combinations of the different variants shown above. Thus it is conceivable that a first receiver 111 has an undercut 40, while a fixing ring 50 is inserted into the second receiver or a corresponding radial bore 60 is configured. All possible combinations of the above-described variants are conceivable.

    [0048] In any case, in a bearing arrangement 10, but in particular in a bearing arrangement 10 comprising axially pretensioned cone bearings, comprising a bearing receiver 100 which has at least one receiver region 111, 112 for a shaped body 20, 21, a resilient shaped body 20, 21 is inserted into the receiver region 111, 112. The resilient shaped body 20, 21 is held so as to be pretensioned by means of a pretensioning device 30. The pretensioning device 30 has a bearing core 31. The bearing core 31 extends in the axial direction x through the shaped bodies 20, 21. The receiver region 11 has a base 12 with a through-hole 13. The base 12 is arranged between the first receiver 111 and the second receiver 112. The base 12 forms a limit for the shaped body 20, 21 in the axial direction x.

    [0049] One or both of the receivers 111, 112 can have a first region 113 and a second region 114 in the axial direction x. The first region 113 is configured in the axial direction x on the side of the receiver 111, 112 facing the base, and the second region 114 is configured on the side remote from the base. At least one of the two regions 113, 114 can be configured to be cylindrical, while the other region is configured to be entirely or partially conical. It is also conceivable that both regions 113, 114 are configured to be cylindrical. In this regard, both the first region 113 and the second region 114 can form a radial cylindrical limit portion 41.

    [0050] All of the features and advantages set forth in the claims, the description and the drawing, including structural details, spatial arrangements and method steps, can be essential to the invention both individually and also in very different combinations.
