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 the axis of the hub. The pulley has at least one passage provided with an inlet adjacent the hub and an outlet adjacent the peripheral groove whereby fluid passing through the passage from the inlet to the outlet thereof will tend to cool the pulley and/or the belt as the pulley rotates about the axis of the hub. A rotatably operable fluid flow forcing unit is carried by the pulley so as to be rotated and thereby operated in unison with the pulley and is disposed upstream from the inlet for forcing fluid into the inlet and thus through the passage as the pulley and the fluid flow forcing unit rotate about the axis of the hub.
