PCT No. PCT/FI89/00136 Sec. 371 Date Jan. 22, 1991 Sec. 102(e) Date Jan. 22, 1991 PCT Filed Jul. 21, 1989 PCT Pub. No. WO90/01129 PCT Pub. Date Feb. 8, 1990.A variable transmission or variator uses a particular V-belt pulley. This pulley is connect to a flexible link for transmitting a driven or driving force. The pulley consists of two disklike sheaves which are variably pressed together. To reduce power losses, bearings for the sheaves assure that the sheaves are either non-loaded or not loaded parallel, but rather are variably inclined to each other. Then, the groove between the sheaves is at its maximum width approximately at the points where the belt leaves the driving pulley and comes onto the driven pulley.
