METHOD OF MANUFACTURING CVT BELT

摘要

In order to restrain the length of an endless metal ring from dispersing, a method of manufacturing a CVT belt has a first-stage stretching step of extending a circumferential length of an endless metal belt by widening distances among rollers. The method includes a measuring step of measuring a spring-back amount of the endless metal belt in the first-stage stretching step. The method includes a calculating step of calculating a predicted spring-back amount that is predicted from the measured spring-back amount. The method also includes a second-stage stretching step of stretching the endless metal belt to process the endless metal belt into a predetermined circumferential length by further widening the distances among the rollers based on the predicted spring-back amount.

主权项

1. A method of manufacturing a CVT belt in which an endless metal belt is retained from inside by at least two rollers and is processed to have a predetermined circumferential length by widening a gap between the rollers, the method comprising:
a first-stage stretching step of stretching the endless metal belt to extend a circumferential length of the endless metal belt by widening a distance between the rollers; a spring-back measuring step of measuring a spring-back amount of the endless metal belt in the first-stage stretching step; a calculating step of calculating a predicted spring-back amount from the measured spring-back amount, the predicted spring-back amount being predicted to result in a second-stage stretching step; and the second-stage stretching step of stretching the endless metal belt and processing the endless metal belt to have the predetermined circumferential length by further widening the distance between the rollers based on the predicted spring-back amount.
