SUPERFINISHING DEVICE, SUPERFINISHING METHOD, AND OUTER RACE OF BEARING WITH SUPERFINISHED RACEWAY SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a superfinishing device that can perform the uniform axial direction finishing of the logarithmic crowning surface formed on the inner circumferential surface of a circular member in a short time, and to provide a superfinishing method, and an outer race of a bearing having a raceway surface that has been superfinished using the superfinishing method.;SOLUTION: The superfinishing device 1 includes a reciprocating linear movement mechanism 40 that reciprocally moves a grindstone 3 that is held in a pressing part 30 linearly in a direction C that is slanted by a constant angle φ with respect to the central axis O of the outer race 10 along a surface B that contacts with the logarithmic crowning surface generating line.;COPYRIGHT: (C)2013,JPO&INPIT
