Abstract
Official abstract text for this publication.
A method for manufacturing an endless metal belt used in a belt-type continuously variable transmission, wherein a stress-relief heat treatment is performed after the circumference of a ring body has been adjusted, and aging/nitridation is performed after the stress-relief heat treatment.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing an endless metal belt to be used in a continuously variable transmission, the method including: performing a stress-relief heat treatment of a ring body after the ring body is subjected to a circumferential length adjusting work, and then, without performing another circumferential length adjusting work, performing an aging-nitriding treatment of the ring body after the stress-relief heat treatment. 2. The method for manufacturing an endless metal belt according to claim 1 , wherein the circumferential length adjusting work is performed after the ring body is subjected to rolling work. 3. The method for manufacturing an endless metal belt according to claim 1 , wherein the stress-relief heat treatment is performed on a plurality of ring bodies in a lamination state, each of the ring bodies having been subjected to the circumferential length adjusting work.
