Embodiment Construction

[0020] As can be seen from a cross-sectional view of a bearing component 1 according to the invention, the bearing component 1 comprises a base part 2 comprising an opening 3 . The opening 3 of the present embodiment is formed as a through opening.

[0021] The opening 3 is configured cylindrically and has a diamond coating 4 on the inner bearing surface 20 of the base body 2 . The diamond coating 4 is formed on the entire inner bearing surface 20 of the opening 3 .

[0022] The opening 3 forms an inner bearing surface and serves to accommodate, for example, a shaft mounted in the opening 3 in a manner to be rotatable in forward and reverse circumferential directions.

[0023] Furthermore, a first bevel 5 is formed on the first side 31 of the opening 3 , and a second bevel 6 is formed on the second side 32 of the opening 3 . The bearing member 1 of the present embodiment is formed as a radial sliding bearing.

[0024] figure 2 is an enlarged detail view of the surface of ...

Abstract

Disclosed is a bearing component comprising a main member (2) and an opening (3) in the main member (2) on which an inner bearing face is formed. The inner bearing face is provided with a diamond coating (4) that has elongate depressions (42) extending substantially in the longitudinal direction (X-X) of the opening.

Description

technical field [0001] The invention relates to a bearing component comprising an inner bearing surface with a diamond coating. Background technique [0002] In principle, it is known from the prior art to provide slip rings or the like with a diamond coating on the outside. Traditionally this has been achieved by CVD methods. However, coating diamond, for example on the inner surface of a bearing, is problematic. DE10809675C1 discloses a device and method for applying a diamond layer to a tubular hollow body of limited length. In this context, a wire is passed through a hollow body and used to deposit diamond particles on the inner surface to be coated. The diamond coating performed by this method results in a homogeneous diamond layer being produced on the inner surface of the hollow body. Contents of the invention [0003] It is an object of the present invention to provide a bearing component which has optimal hydrodynamics and a simple construction and which is si...
