ABSTRACT:
A continuously variable speed transmission has two adjustable sheaves and an endless chain or belt which is trained over and transmits torque between the sheaves. One of the sheaves can be driven by a prime mover, and the other sheave can drive a torque receiving device. Each sheave has a shaft, a first flange which is fixed to the shaft, and a second flange which is movable axially of the shaft toward and away from the first flange. The shaft portion between the flanges of at least one of the sheaves is located in the path of one or more sprays of a cooling and/or lubricating fluid which flows axially of the shaft and along the confronting conical surfaces of the flanges. The spray or sprays are supplied by the nozzle(s) of a conduit which receives fluid from a pump in the hydraulic system of the transmission.
