METHOD FOR PRODUCING ROLLING BEARING CONSTITUTING MEMBER, AND ROLLING BEARING

摘要

PROBLEM TO BE SOLVED: To prolong the service life of a rolling bearing by restraining the breakage of the inner starting point. SOLUTION: An inner ring 1 and an outer ring 2 are produced by using steel satisfying equation (2) in the relation of DI value indicated with equation (1) and the thickness t(mm). (1) DI=(0.2[C]+0.128)(1+0.7[Si])(1+3.45[Mn])(1+0.07[Ni]+0.27[Ni][Ni])(1+2[Cr])(1+2.5[Mo])(1+0.35[Cu]). (2) DI/t≥0.45. COPYRIGHT: (C)2009,JPO&INPIT
