Embodiment Construction

[0022] figure 1 or figure 2 A bearing component designed as a rolling bearing cage 1 is shown, the main body of the rolling bearing cage 1 comprising a matrix 2 of hardened photopolymer and a coating 3 of nanocrystalline metal. Coating 3 has a substantially uniform thickness of approximately 20 micrometers to approximately 1000 micrometers (currently approximately 1000 micrometers) and is fixed on substrate 2 . In order to increase the adhesion of the nanocrystalline coating 3 to the substrate 2 , an intermediate layer is provided, the layer thickness of which is only a few micrometers and therefore negligible compared to the layer thickness of the nanocrystalline coating 2 . The nanocrystalline coating 2 is composed of an iron-nickel alloy, the grains of which have an average particle diameter of less than about 500 nanometers.

[0023] The base body 2 is designed here as a hollow part which has a two-dimensional surface which is essentially closed in three dimensions and ...

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.

Description

technical field [0001] The invention relates to a bearing component of a rolling or plain bearing, in particular a rolling bearing cage of a rolling bearing, and a method for producing such a bearing component, in particular of the bearing cage. [0002] The invention is explained and described in detail below with reference to a bearing cage as a bearing component of a rolling bearing; however, it should be considered that the description is equally applicable to other bearing components of a rolling or sliding bearing, for example for bearing rings or guides of rolling or sliding bearings Ring or sealing element or part thereof. Background technique [0003] It is known from practice to manufacture rolling bearing cages, for example from metal or plastic. In particular plastic cages are known which are coated with metal. Difficulties arise when only a small number of cages are to be produced, since known production methods are designed and optimized for mass production. ...
