ABSTRACT:
A metal ring with smaller stress concentration is manufactured, and the manufacture and maintenance of a rolling roller for transferring a mesh-shaped unevenness to the metal ring is facilitated. A mesh-like unevenness8is formed to the surface of an inner circumference rolling roller6. This unevenness8is formed by rotating the inner circumference rolling roller6at a predetermined speed, and moving a grinder9back and forth in the axial direction of the inner circumference rolling roller6while biasing the grinder toward the surface of the roller6with predetermined force. The grain size of the grinder is between #270 and #1000. When the inner circumferential surface of the metal ring1is rolled using the inner circumference rolling roller6, a mesh-like unevenness2is transferred onto the metal ring1. Since the mesh-like unevenness2is formed by transferring the unevenness8having been formed by the grinder9, the pitch of the unevenness is narrow and random, thus the laminated metal ring1exerts good lubricity. Moreover, by subjecting the metal ring1to solution treatment and nitriding treatment, a metal ring1having high compressive residual stress and enhanced toughness is formed.
