Bearing ring manufacturing method for swivel-joint roller bearing that is utilized in smithy, involves forming strip material portion and connecting annular elements to ends of butt joint based on external periphery of bearing ring

摘要

The method involves forming a strip material portion and connecting mirror-symmetric annular elements (3) to ends of a butt joint based on an external periphery (6) of a bearing ring (2). The annular elements are assembled to another bearing ring and interconnected to a component by a welding. A cross-sectional profile of the latter bearing ring is formed in the component. The strip material is formed by a cold rolling based on a cross-cutting. A plane of symmetry of the annular elements is vertically assembled to axles of the latter bearing ring.
