Title:
METHOD FOR MANUFACTURING MECHANICAL PARTS WITH SUPERIOR ROLLING FATIGUE LIFE
Document Type and Number:
WIPO Patent Application WO/2013/085008
Kind Code:
A1
Abstract:
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.
