Abstract
A belt pulley and method of making the same are provided, the pulley having a hub and a peripheral groove for receiving part of an endless belt therein that is to drive the pulley or be driven thereby whereby the pulley is adapted to be rotated about a longitudinal axis of the hub. The pulley has a pair of opposed facing sides defining at least part of the groove therebetween and has a pair of oppositely facing outboard sides, the sides each having an inner peripheral portion and an outer peripheral portion. The pulley has a plurality of circumferentially spaced apart and radially disposed substantially straight vanes extending outwardly from at least one of the outboard sides thereof. Each vane has an inner peripheral end and an outer peripheral end respectively disposed adjacent the inner peripheral portion and the outer peripheral portion of its respective outboard side and has an outer edge that is disposed substantially transverse to the longitudinal axis of the hub from substantially the inner peripheral end thereof to the outer peripheral end thereof and is spaced outwardly from the respective outboard side from substantially the inner peripheral end thereof to the outer peripheral end thereof whereby the vanes are adapted to act on fluid adjacent to pulley to tend to cool the pulley with the fluid.
