Abstract

A rolling-element bearing which has at least one inner ring and at least one outer ring. A relative movement is possible between the outer ring and the inner ring, and the at least one outer ring having has at least one flange for fastening to a rotatable component.

Claims (15)

1. A transmission or clutch including a rolling bearing, the rolling bearing comprising:

at least one inner ring and at least one outer ring, a relative movement being possible between the at least one outer ring and the at least one inner ring,

wherein the at least one outer ring is designed as a single one-piece part that includes at least one flange fastened to a rotatable component of the transmission or clutch, and

wherein the at least one inner ring is designed as a single one-piece part having a plurality of fastening flanges fastening the at least one inner ring to a stationary component, the plurality of fastening flanges being spaced at regular intervals from one another in a circumferential direction on a lateral face of the at least one inner ring, and wherein each of the fastening flanges includes an axial recess at a base of the each of the fastening flanges, the axial recess facing a space between the at least one inner ring and the at least one outer ring.

2. The transmission or clutch as claimed in claim 1 , wherein the at least one flange is a clutch plate of the transmission or clutch.

3. The transmission or clutch as claimed in claim 1 , wherein the at least one flange is formed circumferentially on the at least one outer ring.

4. The transmission or clutch as claimed in claim 1 , wherein the at least one flange is cold-formed or forged with the at least one outer ring.

5. The transmission or clutch as claimed in claim 1 , wherein the at least one flange has fastening devices for fastening the at least one flange to the rotatable component.

6. The transmission or clutch as claimed in claim 1 , wherein the rolling bearing is a deep-groove ball bearing, a four-point contact ball bearing or an angular-contact ball bearing.

7. The transmission of clutch as claimed in claim 1 , wherein the each of the fastening flanges comprises an axially extending centering lug on a side of the each fastening flange opposing the axial recess.

8. The transmission or clutch as claimed in claim 1 , wherein the rolling bearing is designed to support a clutch unit or for use as a support bearing in dual clutch transmissions.

9. The transmission or clutch as claimed in claim 1 , wherein the rolling bearing supports an input side of the clutch.

10. The transmission or clutch as claimed in claim 1 , wherein the at least one flange includes a contact surface and bores, which open through the contact surface, for receiving connection bolts.

11. The transmission or clutch as claimed in claim 10 , wherein the contact surface contacts a pressure plate of a clutch.

12. The transmission or clutch as claimed in claim 1 , wherein the inner ring includes fitting recesses between the plurality of flanges allowing access to seals of the bearing facing the flange.
