SHAFT OF BELT-TYPE CONTINUOUSLY VARIABLE TRANSMISSION, STATIONARY SHEAVE HALF FOR CONTINUOUSLY VARIABLE TRANSMISSION, METHOD FOR PRODUCTION THEREOF, AND CONTINUOUSLY VARIABLE TRANSMISSION

摘要

The position of a ball bearing (18) on a shaft (16) may be fixed, press fitting a sheave portion (10) onto the shaft (16) and sandwiching the ball bearing (18) between a flange (16a) and the sheave portion (10). Thus, the axial dimension of a stationary sheave half (4) for a continuously variable transmission may be reduced. Because one end (10c) of the sheave portion (10) is in contact with the ball bearing (18), thrust force from the sheave portion (10) is transmitted via the ball bearing (18) to the flange (16a), which will not loosen and, thereby, the structural integrity of the stationary sheave half (4) is maintained.
