Embodiment Construction

[0043] In the following, identical or functionally equivalent elements are denoted by the same reference numerals.

[0044] exist figure 1 The rolling bearing 1 is drawn with a greatly simplified outline in . The rolling bearing 1 includes an inner ring 2 and an outer ring 4 . Rolling elements 6 are rotatably arranged between the two rings 2 , 4 . The rolling elements 6 may be kept spaced apart from each other by cages, not shown. Alternatively, instead of the rolling bearing 1 , the bearing can also be a plain bearing.

[0045] The individual components of the rolling bearing 1 , such as the inner ring 2 , the outer ring 4 or the rolling elements 6 , can be provided as metallic rolling bearing or sliding bearing components with non-sandblasted surfaces. Here, at least one non-blasted surface may be provided with at least one partial ( / partial) metallic coating. Here, the metallic coating is applied ( / applied) directly onto the non-blasted surface using a cold spray metho...

Abstract

Disclosed is a metallic rolling or a bearing component (2, 4). The invention includes at least one unblasted surface and at least one portion of metal coating, wherein the metal coating is applied directly to the unblasted surface using a cold spray method.

Description

technical field [0001] The present invention relates to a metal rolling bearing or sliding bearing component part according to the preamble of technical solution 1 of the present invention, which comprises at least one part of a metal coating, and to a use according to the preamble of technical solution 7 of the present invention. A method for producing a metallic rolling bearing or plain bearing component comprising at least one partial metallic coating. Background technique [0002] Rolling or plain bearing components, especially of large bearings, often receive galvanization (galvanization) on their outer surfaces as a metallic coating (eg corrosion protection). To date, flame spray galvanizing ( / electroplating) has often been used in addition to coatings comprising zinc-containing paints. This galvanizing ( / electroplating) also offers the advantage that zinc provides high friction values, which is advantageous for surfaces used for screwing or flanging of bearings. [...
