Abstract

A bearing ring includes a temperature compensation ring made from an elastic material vulcanized or otherwise materially bonded onto an outer surface of the bearing ring, the outer surface being oriented in a radial direction. The bearing ring includes a radially encircling groove, and in an unloaded state of the temperature compensation ring, that is, independently of an application of axial pressure against the temperature compensation ring, the temperature compensation ring fills the groove in an interference-fit manner.

First claim

What is claimed is:

1. A bearing ring including a temperature compensation ring made from an elastic material vulcanized onto an outer surface of the bearing ring, the outer surface being oriented in a radial direction, such that first and second surfaces of the temperature compensation ring contact the bearing ring and third and fourth surfaces of the temperature compensation ring contact a housing,
wherein the bearing ring further includes a radially encircling groove, and
wherein in an unloaded state of the temperature compensation ring, the temperature compensation ring fills the groove in an interference-fit manner.

2. The bearing ring according to claim 1 , wherein the temperature compensation ring comprises an elastomer.

3. The bearing ring according to claim 1 , further comprising a first region and a second region on the outer surface,
wherein the second region has a larger diameter than the first region, and
wherein between the first region and the second region the temperature compensation ring abuts on an end surface oriented in an axial direction.

4. The bearing ring according to claim 3 , wherein the groove is disposed at the boundary between the first region and the second region.

5. The bearing ring according to claim 1 , wherein the bearing ring is an outer ring and the outer surface is oriented radially outward.

6. A bearing including the bearing ring according to claim 1 .

7. The bearing ring according to claim 1 , further comprising a first region and a second region on the outer surface,
wherein the second region has a larger diameter than the first region,
wherein between the first region and the second region the temperature compensation ring abuts on an end surface oriented in an axial direction,
wherein the groove is disposed on the boundary between the first region and the second region, and
wherein the temperature compensation ring comprises an elastomer.

8. The bearing ring according to claim 1 , wherein the temperature compensation ring has a first side and a second side substantially perpendicular to the first side and an annular bead connecting the first side to the second side.

9. The bearing ring according to claim 1 , wherein the temperature compensation ring fills the groove in the interference-fit manner independently of an application of axial pressure against the temperature compensation ring.

10. A bearing ring including a temperature compensation ring made from an elastic material materially bonded onto an outer surface of the bearing ring, the outer surface being oriented in a radial direction, such that first and second surfaces of the temperature compensation ring contact the bearing ring and third and fourth surfaces of the temperature compensation ring contact a housing,
wherein the bearing ring further includes a radially encircling groove, and
wherein the temperature compensation ring fills the groove in an interference-fit manner independently of an application of axial pressure against the temperature compensation ring.

11. The bearing ring according to claim 10 , wherein an elastic material materially bonded onto an outer surface comprises the elastic material vulcanized onto the outer surface.

12. The bearing ring according to claim 10 , wherein the temperature compensation ring has a first side and a second side substantially perpendicular to the first side and an annular bead connecting the first side to the second side, the annular bead being located in the groove.
