FIXED SHEAVE FOR STEPLESS TRANSMISSION, METHOD FOR MOUNTING THE FIXED SHEAVE, AND METHOD FOR MANUFACTURING THE FIXED SHEAVE

摘要

A fixed sheave is formed by pressing fitting and integrating a sheave portion and a shaft that have been shaped separately. The shaft is formed in a stepwise manner, and has a bearing disposition portion at one end of the shaft and a sheave portion fixing section that has a diameter smaller than that of the bearing disposition portion, and that is on an opposite side of the step from the bearing disposition portion. The sheave portion is fixed to the sheave portion fixing section in abutment, against the step, with a rear surface of the sheave portion facing the one end of the shaft. A finish processing is performed to either or both of the sheave portion and the shaft after the fixing. A first bearing is inserted from the one end of the shaft and disposed at the bearing disposition portion after the finish processing.
