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

A bearing component is disclosed, comprising: a base body (2) and an opening (3), the opening (3) being in the base body (2) and having an inner bearing surface formed in the opening (3). The inner bearing surface is provided with a diamond coating (4) having an elongated recess (42) extending substantially along the length 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. DE 108 09 675 C1 discloses a device and a 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...
