Method of producing a raceway ring inner ring or outer ring and raceway ring

摘要

A raceway ring 212, 220 for a bearing 200 comprising printed material 250, 255, 260 is produced by the steps of: separating a ring-shaped part (130, fig 1A) from a metal tube (100, fig 1A), the ring-shaped part comprising a raceway surface, and generating an attachment element 245, (247 or 248, fig 3B) on the ring-shaped part for generating the raceway ring. Further machining of the raceway ring may be required for generating a specific shape of the raceway ring. The attachment element 245, (247 or 248, fig 3B) is configured to improve a bonding between printed material and the raceway ring and may comprise circumferential, axial or radial groove(s) and/or an array of indentations. The inner ring or outer ring comprises the raceway ring and added printed material by an additive manufacturing process, such as direct laser deposition, to the raceway ring. The printed material is used to customize the inner and outer shape of the bearing.
