METHOD FOR MANUFACTURING MECHANICAL PARTS WITH SUPERIOR ROLLING FATIGUE LIFE

摘要

Disclosed is a method for manufacturing ring-shaped mechanical parts having a rolling part with superior rolling fatigue life on an inside diameter surface. This method for manufacturing is carried out by forming the rolling part on which a rolling component rolls on the inside diameter surface of a ring-shaped material by a forging process that imparts hydrostatic pressure stress for contraction to the inside diameter surface of the ring-shaped material such that the rolling part is formed.
