Abstract
A variable-speed belt drive pulley assembly includes a plurality of pulley segments, a plurality of sliders, and a rotatable hub. Each segment is adapted to engage a drive belt and is mounted to an outer end of a corresponding slider which is slidably received by the hub. Each slider may be a pair of rods extending from the body in parallel relationship to each other. The hub has a plurality of bores. Each bore slidably receives a corresponding one of the rods. An actuator device moves the segments radially inwardly and outwardly with respect to the hub. A coil spring is mounted on each the rods, and is biased to urge one of the segments radially outwardly.
