Abstract
A method for producing a roller bearing cage (1) is provided, including the following steps: a base body (2) which is close to a net shape is produced by a stereolithography method or by a 3D-printing method, and the provided base body (2) is coated with a thin, nanocrystalline coating (3). A roller bearing cage, including a base body (2) and a nanocrystalline coating (3) fixed to the base body (2) produced by this method is also provided. This method is suitable for producing roller bearing cages in only small quantities in a small series.
Claims11
A method for producing a roller bearing cage, comprising the following steps:
- providing an integrally formed near net shape base body that defines the roller bearing cage structure produced by a stereolithographic method or by 3D printing, and
- coating the integrally formed near net shape base body with a thin, nanocrystalline coating.
A roller bearing cage comprising an integrally formed near net shape base body that defines the roller bearing cage structure produced by a stereolithographic method or 3D printing, and a nanocrystalline coating fixed over an entire surface of the integrally formed near net shape base body.
