ABSTRACT:
A variable speed pulley mounted to a torque transmission shaft having an idler structure arranged to maintain the power transmission belt centered between the pulley sheaves when the sheaves are spaced apart sufficiently to permit the belt to ride on the idler as in a stopped or idling condition of the pulley system. A tension roller may be utilized in the system for urging the belt against the outer surface of the idler, which, in the illustrated embodiment, is crowned. Structure is provided for affording facilitated adjustable movement of the adjustable sheave on the shaft, and in one embodiment, provision is made for providing lubrication therebetween.
