Abstract

The invention relates to a pivot bearing insert for a bearing body (1) consisting of two bearing parts (2, 3) which can pivot about a pivot axis (5) and between which the pivot bearing insert (6) is located. The invention is characterized in that the bearing insert consists of two bearing bushes (7) which slide into each other and which are provided with bearing surfaces (9) which slide into each other and outer surfaces which face towards the respective bearing part (2, 3). The bearing surfaces (9) which slide into each other are smooth and free of play, while the outer surfaces are rough and are solidly connected to the respective bearing part (2, 3). A pivot bearing insert (6) of this type is simple to produce and is well protected against wear and tear. The invention also relates to a bearing produced with at least one pivot bearing insert (6) of this type.

Claims

1. Pivot bearing insert for a bearing body (1;

101, 201, 301, 401, 501, 601, 701, 801), which consists of at least two bearing parts (2, 3;

102, 103;

. . . 802, 803), which can be rotated relative to one another about an axis of rotation (5, 105 . . . 805) and between which the pivot bearing insert (6, 106 . . . 806) is disposed, wherein the pivot bearing insert part consists of two bearing bushings (7, 8;

107, 108;

. . . 807, 808), which slide one inside the other and are provided with bearing surfaces (9, 109;

. . . 809), which slide one inside the other and with external sides facing the respective bearing parts (2, 3;

102, 103;

. . . 802, 803), the bearing surfaces (9, 109 . . . 809), which slide one inside the other, being constructed smoothly and without clearance, while the external sides are roughened and permanently connected with the respective bearing parts (2, 3;

102, 103;

. . . 802, 803).

2. The pivot bearing insert of claim 1, wherein the bearing bushings (7, 8;

107, 108;

. . . 807, 808), which slide one inside the other, have, at least at one end, an edge (12, 112 . . . 812), which is perpendicular to the axis of rotation (5, 105 . . . 805).

3. The pivot bearing insert of claims 1 or 2, wherein at least one of the bearing bushings (7, 8;

107, 108 . . . 807, 808), has a hat-shape because one end face is closed up.

4. The pivot bearing insert of one of the claims 1 to 3, wherein the bearing surfaces (9, 109 . . . 809) are cylindrical surfaces.

5. The pivot bearing insert of one of the claims 1 to 4, wherein the two bearing bushings (7, 8, 107, 108;

. . . 807, 808), which slide one inside the other, consist of different materials.

6. The pivot bearing insert of one of the claims 2 to 5, wherein the two bearing bushings (7, 8, 107, 108;

. . . 807, 808), which slide one inside the other, have edges (12, 112 . . . 812), which rotate parallel to one another and also slide one inside the other.

7. The pivot bearing insert of one of the claims 1 to 6, wherein the two bearing bushings (307, 308;

607, 608), which slide one inside the other, have radially extending sections and can adjustably be pressed against one another axially.

8. The pivot bearing insert of one of the claims 1 to 8, wherein an inner bearing bushing (407, 507) is constructed hat-shaped and, at its closed end, has a peripheral, inwardly formed groove (419, 619), which is parallel to its closed end and into which a retaining ring (420, 520) can be inserted for fixing the outer bearing bushing (408, 508).

9. The pivot bearing insert of one of the claims 2 to 8, wherein the two bearing bushings (207, 208, 707, 708), which slide one inside the other, have at one end a peripheral edge (212, 712), so that both edges (212, 712) extend parallel to one another.

10. The pivot bearing insert of one of the claims 1 to 9, wherein, in at least one of the surfaces (209, 709) of the two bearing bushings (207, 208;

707, 708), a peripheral space (216, 716) is formed to accommodate long-term lubrication.

11. A bearing with a bearing body (1, 101, 201, 301, 401, 501, 601, 701, 801) of at least two bearing parts (2, 3:

102, 103;

. . . 802, 803), which can be rotated relative to one another about an axis of rotation (5, 105;

. . . 805) and with a pivot bearing insert (6, 106;

. . . 806) of one of the claims 1 to 10, which is disposed between the two rotatable bearing parts.

12. The bearing of claim 11, for which the bearing part insert (6, 106, 806), is cast in the bearing body (1, 101, 201, 301, 401, 501, 601, 701, 801).

13. The bearing of claims 11 or 12, in which a bearing part (103, 203, 303, 403, 503, 603, 703, 803) extends through the inner bearing bushing (107, 307, 407, 507, 606, 707, 807) and forms a concluding flange (114, 214, 420, 623, 714, 814).

14. The bearing of one of the claims 11 to 13, for which one of the bearing parts (3, 103 . . . 803) forms an axle part (4, 104, . . . 804).

15. The bearing of one of the claims 11 to 14, for which at least two pivot bearing inserts (6) are connected with an axle part (4) of the bearing.

16. The bearing of one of the claims 11 to 16, wherein it is constructed so that it can be disassembled and assembled once again.
