Abstract
The variable diameter pulley has two pulley cheeks which can slide axially along the carrier hub (1). Between the outer end of each pulley and the end of the hub are fixed a pair of concentric sprung steel washers (3) that keep the cheeks biassed axially upwards. This ensures that whatever the position of the belt (4) between the cheeks, there will be sufficient cheek/belt/cheek compression to permit drive. The sprung steel washers are riveted together at their outer peripheries, and one pulley cheek is slidable over a sleeve of the other cheek which is mounted on a shaft.
