Abstract

A component of a universal joint bearing includes at least one casing having a cylindrical wall and a base and at least one formation projecting from the base. The at least one formation is receivable in a clamp of a rotational processing machine to secure the component to the rotational processing machine during a rotational machining of a wall of the component. Also a method that includes clamping the component by the formation and machining inner and outer surfaces of the component without unclamping the component.

First claim

What is claimed is:

1. A component of a universal joint bearing comprising:
at least one radially outer surface region that has the shape of a cylindrical casing,
a base that includes a flat base surface on an outer side, and
at least one cylindrical formation projecting from the base, the cylindrical formation provides a clampable surface for a rotational machining of a wall of the at least one radially outer surface region.

2. The component according to claim 1 , wherein the formation is an elevation extending away from an inner side of the component starting from a surface of the base.

3. The component according to claim 1 , wherein the elevation has at least one height of 0.5 mm relative to the base surface.

4. The component according to claim 1 , wherein the elevation has at least one height of at least 0.1 mm relative to the base surface.

5. The component according to claim 1 , wherein the formation is substantially pot-shaped.

6. The component according to claim 1 , including a raceway on an inner side configured to support a plurality of rolling elements.

7. The component according to claim 6 , including the plurality of rolling elements.

8. The component according to claim 1 , wherein the elevation has at least one height of at least 0.1 mm relative to the base surface,
wherein the formation is substantially pot-shaped, and
including a raceway on an inner side of the component configured to support a plurality of rolling elements.

9. A universal joint bearing including the component of claim 1 .

10. A method for processing a wall of a component of a universal joint bearing, the method comprising:
clamping the component by a formation on a base of the component, while the component is clamped,
machining an inner cylindrical surface or an outer cylindrical surface of the component, and without unclamping the formation,
machining the outer cylindrical surface or the inner cylindrical surface of the component.

11. The method according to claim 10 , wherein the machining comprises a rotational machining.

12. The method according to claim 10 , wherein the formation has at least one height of 0.5 mm relative to the base.

13. The method according to claim 10 , wherein the elevation has at least one height of at least 0.1 mm relative to the base.

14. The method according to claim 10 , wherein the formation is substantially pot-shaped.
