Abstract
A method of making bearing bushes by joining together a plurality of segments along joints parallel to the bearing axis. In the preferred method, two semicylindrical segments are used, and are joined by electron beam welding. The welding is the last operation in the manufacture of the bush.
Claims4
A method of producing a bearing in which a bush for insertion in a bearing housing is produced by the steps of
- pressing from flat sheet material comprising a strong backing and a layer of bearing lining, two semi-cylindrical bearing bush segments each segment having a convex surface, a concave inner surface, a pair of part annular end faces, and a pair of side faces;
- assemblying said bearing bush segments to form a complete annular bush pre-assembly in which side faces of adjacent segments are close to one another but separated by a V-groove;
- welding together adjacent segments of said pre-assembly by deposition of metal in the V-grooves in contact with the side faces of the backings but not in contact with the linings to provide a complete self-supporting bush having an essentially continuous internal cylindrical bearing surface;
- and
- then inserting the bush in the bearing housing in which method a plurality of segments are supported to form a plurality of bushes arranged end to end, and are joined, except along the end faces of said bushes, in a single operation.
