Abstract

A bearing ring for a rolling-element bearing includes a rolling-element raceway that is axially delimited by a guide flange and a retaining flange. At least the retaining flange is configured as a separate element that is fixedly connectable to the bearing ring, and the bearing ring includes a substantially radially extending stop that is offset inward from an axial end of the bearing towards the raceway.

First claim

The invention claimed is:

1. A bearing ring for a rolling-element bearing, comprising:
a rolling-element raceway that is axially delimited by a guide flange and a retaining flange configured as a separate element that is fixedly connectable to the bearing ring, the retaining flange having a stop surface and a rolling-element retaining surface extending in a radially outward direction from the stop surface to a rolling-element mounting surface, the rolling-element mounting surface extending in a radially inward direction from the rolling-element retaining surface to an axial surface, the axial surface extending radially from the rolling-element mounting surface towards the bearing, and
a stop formed in the bearing ring, the stop extending substantially in a radial direction, and offset inward from an axial end of the bearing towards the raceway.

2. The bearing ring according to claim 1 , wherein the stop is configured to establish a defined axial position of the retaining flange, and wherein the axial position defines a maximum clear flange width between the guide flange and the retaining flange.

3. The bearing ring according to claim 1 , wherein the retaining flange is connected to the bearing ring in a friction-fit, material-bonded, and/or interference-fit manner, and wherein the retaining flange is shrunk-on and/or adhered-on.

4. The bearing ring according to claim 3 , further comprising:
a retaining flange receiving surface on the bearing ring,
wherein the retaining flange includes a support surface substantially parallel to the retaining flange receiving surface and the stop surface is substantially parallel to the stop, wherein the support surface of the retaining flange is disposed on the retaining-flange receiving surface with a friction-fit and/or with a material-bonding.

5. The bearing ring according to claim 4 , wherein the retaining flange includes an oblique retaining-flange mounting surface between the retaining flange stop surface and the retaining flange support surface, and
wherein an angle (γ) between the retaining-flange mounting surface and the retaining flange support surface is 120° to 150°.

6. The bearing ring according to claim 1 , wherein a substantially axially extending retaining-flange receiving surface is formed on the bearing ring, and wherein the stop delimits the retaining-flange receiving surface axially inward toward the raceway, and wherein the retaining-flange receiving surface extends radially and axially with respect to an axis of rotation of the bearing ring.

7. The bearing ring according to claim 6 , wherein the stop extends from the retaining-flange receiving surface to the raceway.

8. The bearing ring according to claim 1 , wherein a substantially axially extending retaining-flange receiving surface is formed on the bearing ring, and wherein the stop delimits the retaining-flange receiving surface axially inward toward the raceway, and wherein the retaining-flange receiving surface is inclined with respect to an axis of rotation of the bearing ring towards the radial stop at an angle of inclination (δ) of less than 5°.

9. The bearing ring according to claim 1 , wherein the bearing ring has an axis of rotation, and
wherein the rolling-element retaining surface extends radially and axially with respect to the axis of rotation of the bearing and extends between the stop surface and the rolling-element mounting surface and the rolling-element retaining surface faces the raceway, and
the rolling-element mounting surface extends radially and axially with respect to the axis of rotation of the bearing.

10. The bearing ring according to claim 9 , wherein the rolling-element retaining surface is substantially perpendicular to the raceway.

11. The bearing ring according to claim 9 , wherein an angle (β) between the rolling-element retaining surface and the raceway is 80° to 100°.

12. A tapered rolling-element bearing including the bearing ring according to claim 1 .

13. The bearing ring according to claim 1 , wherein the rolling-element retaining surface faces the raceway and the rolling-element mounting surface faces away from the raceway.

14. The bearing ring according to claim 13 , wherein an edge formed between the rolling-element retaining surface and the rolling-element mounting surface is rounded.

15. The bearing ring according to claim 1 ,
wherein the bearing ring includes a substantially axially extending retaining-flange receiving surface and the stop extends from the raceway to the retaining-flange receiving surface,
wherein the retaining flange is connected to the bearing ring in a friction-fit, material-bonded, and/or interference-fit manner,
wherein the rolling-element retaining surface is substantially perpendicular to the raceway and facing the guide flange and the rolling-element mounting surface facing away from an axis of rotation of the bearing ring, and
wherein the retaining flange includes a first surface mounted flush against the stop and a second surface mounted flush against the retaining-flange receiving surface and wherein the first surface is connected to the second surface by an oblique wall spaced from the stop and spaced from the retaining-flange receiving surface, and wherein the oblique wall and the stop and the retaining-flange receiving surface define a hollow space in the bearing ring.

16. A bearing ring for a rolling-element bearing, the bearing ring having an axis of rotation and comprising:
a raceway having a first end and a second end axially spaced from the first end;
a guide flange at the first end of the raceway,
a stop surface extending in toward the axis of rotation from the second end of the raceway,
a retaining-flange receiving surface extending substantially axially away from the stop surface, and
a retaining flange mounted on the bearing ring and having a first surface in direct contact with the stop surface, a second surface in direct contact with the retaining-flange receiving surface, a rolling-element retaining surface extending in a radial direction away from the bearing and facing the guide flange and a rolling-element mounting surface extending in the radial direction from the rolling-element retaining surface towards the bearing.

17. The bearing ring according to claim 16 , wherein the second end is radially spaced from the first end.

18. The bearing ring according to claim 17 , including an oblique surface connecting the first surface and the second surface, wherein the oblique surface, the stop surface and the retaining-flange receiving surface define an annular hollow space in the bearing ring.

19. A tapered rolling-element bearing including the bearing ring according to claim 18 .
