Abstract

A thrust bearing arrangement ( 2 ) is provided having a roller body cage ( 4 ) holding several roller bodies ( 6 ) and at least one race disk ( 8′, 10″ ), with the race disk ( 8′, 10″ ) having a collar ( 12 ) axially surrounding the roller body cage ( 4 ) with play and on the opposite end a flange arrangement, which is directed in the opposite axial direction and in whose internal corner a component contacting the race disk ( 8′, 10″ ) can be centered. To avoid complicated processing of the peripheral edge of the contacting component facing the internal corner ( 22′ ), at least the leg ( 19′, 27 ) of the internal corner ( 22′, 30 ) forming the flange arrangement ( 18′, 26 ) has a relieved inner contour for receiving the component to be centered in the corner region.

Claims (8)

1. Thrust bearing arrangement comprising a thrust bearing and a component centered thereon, the thrust bearing including a roller body cage holding several roller bodies and at least one race disk with the race disk having a collar surrounding the roller body cage axially with play and at an opposite end a flange arrangement, which is directed in an opposite axial direction and in whose internal corner the component contacting the race disk is centered, at least a leg of the internal corner forming the flange arrangement has a relieved inner contour to receive a corner defined by an opening in the component, wherein the internal corner includes an axial surface of the leg, a radial surface of the race disk, the radial surface extending outwardly beyond the axial surface, and an outwardly directed transition region between the axial surface and the radial surface that defines a triangular shaped undercut.

2. Thrust bearing arrangement according to claim 1 , wherein the flange arrangement is provided as an annular flange.

3. Thrust bearing arrangement according to claim 1 , wherein the flange arrangement is composed of several annular flange segments distributed in a peripheral direction.

4. Thrust bearing arrangement according to claim 1 , wherein the flange arrangement is arranged on an outer periphery of the race disk.

5. Thrust bearing arrangement according to claim 1 , wherein the flange arrangement is arranged on an inner periphery of the race disk.

6. Thrust bearing arrangement according to claim 1 , wherein the flange arrangement interacts with a spacing ring.

7. Thrust bearing arrangement according to claim 1 , wherein the flange arrangement interacts with a guiding component centering the thrust bearing arrangement.

8. Thrust bearing arrangement according to claim 1 , wherein the race disk is a sheet-metal ring produced in a stamping and deep-drawing process.
