Increasing tolerable surface pressure of rolling bearing carrier of sulfur-alloyed steel component, by remelting surface layer of rolling bearing carrier using an electron beam, where component rotates about rotational axis of the carrier

摘要

The method comprises remelting a surface layer (2) of a rolling bearing carrier (3) using an energy beam such as an electron beam. The surface layer is remelted to a depth of 50 mu m. The component rotates about a rotational axis of the carrier during remelting of the surface layer of the rolling-carrier. The electron beam is deflected, on adjacently arranged portions of the carrier, to a bearing surface over the entire circumference of the carrier and deflected by a respective one of receptions such as spot on which trajectories are formed.

The method further comprises post-processing the remelted surface layer, and curing an edge of the component using the electron beam in a single production cycle.
