Abstract

A rolling body guide element for a roller bearing, having an inner web (1) that is arranged between two adjacent rolling bodies in the installed state and forms a first and second connecting part wall (1a, 1b) facing a respective rolling body at the radial plane of the rolling body axes, a run-on structure (2) formed in the region of the respective connecting part wall to provide at least one roller run-on zone supporting the respective rolling body in the circumferential direction, and a radial guide structure (3) for radial guidance of the inner connecting part. According to the invention, the rolling body guide element includes first and second side edge pieces (4, 5) which, on sides of the rolling body guide element facing away from one another, rise up above the end faces of the adjacent rolling body and overlap these end faces.

Claims

1. A rolling body guide element for a roller bearing comprising:

an inner connecting part that is arranged in an installed state between two adjacent rolling bodies and forms a first or second connecting part wall turned toward the respective rolling body at a radial plane of the rolling body axes,

a run-on structure constructed in an area of the connecting part wall for preparing at least one roller run-on zone supporting the respective rolling body in a circumferential direction,

a radial guide structure for radial guidance of the inner connecting part, and

first and second side edge parts that rise on sides of the rolling body guide element turned away from each other above end faces of the adjacent rolling bodies and overlap said end faces.

2. The rolling body guide element according to claim 1, wherein the side edge parts are constructed such that adjacent ones of the rolling body guide elements in succession in the circumferential direction are supported by said side edge parts.

3. The rolling body guide element according to claim 2, wherein the side edge parts function as spacers by which a pocket width measured in the circumferential direction is fixed between two of the rolling body guide elements.

4. The rolling body guide element according to claim 1, wherein the radial guide structure has inner guide fingers that run onto a bearing inner ring.

5. The rolling body guide element according to claim 1, wherein the radial guide structure has outer guide fingers that run onto a bearing outer ring.

6. The rolling body guide element according to claim 1, wherein the radial guide structure is constructed such that it fixes an axial position of the rolling body guide elements relative to at least one of a bearing inner ring or a bearing outer ring.

7. The rolling body guide element according to claim 1, wherein the side edge parts fix an axial position of the rolling body guide elements relative to the rolling bodies.

8. The rolling body guide element according to claim 1, wherein the inner connecting part forms, in an area of axial ends thereof, on each side a first and a second roller run-on zone, and each of the roller run-on zones forms a concave run-on surface arrangement picking up the run-on rolling body.

9. The rolling body guide element according to claim 1, wherein the rolling body guide element is made from a plastic material.

10. A rolling body guide element for a roller bearing comprising:

an inner connecting part that is arranged in an installed state between two adjacent rolling bodies and forms a first or second connecting part wall turned toward the respective rolling body at a radial plane of the rolling body axes,

a run-on structure constructed in an area of the respective connecting part wall for preparing at least one roller run-on zone supporting the respective rolling body in a circumferential direction, and

a radial guide structure for radial guidance of the inner connecting part,

wherein the radial guide structure has several guide fingers that are supported by the inner connecting part and extend with a fork shape from the inner connecting part, in their profile from an attachment area on the inner connecting part toward a guide contact area lying axially at a height of axial end areas of the rolling bodies, with formation of intermediate fork spaces.

11. A tapered roller bearing, with:

a bearing inner ring,

a bearing outer ring,

tapered rollers that are held in a roller circulating space formed between the bearing inner ring and the bearing outer ring, the tapered roller have end faces,

rolling body guide elements that are produced as separate insert elements and are each held between two adjacent ones of the tapered rollers,

wherein the rolling body guide elements are each equipped with side edge parts that overlap the tapered rollers in an area of the end faces and are supported against each other in a circumferential direction.
