Method of manufacturing a shaft with surfaces thereof modified |
摘要 |
A method of manufacturing a shaft having modified surfaces. The method comprises forming thread grooves on surfaces of a cylindrical-shaped base material for a shaft, continuously winding a length of wire in and along the thread grooves, and compressing a peripheral surface of the base material for the shaft with the length of wire wound and received in the thread grooves, in a direction of diameter reduction to perform plastic deformation of crests of thread ridges between the adjacent thread grooves or the crests and the wire to have the length of wire being fixed to and united with the base material for the shaft. The method improves the hardness of surfaces of a base material for a shaft in a relatively simple manner, and transforms properties of surfaces of the base material for a shaft to make the base material for the shaft applicable to other uses.
