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 a plurality of vanes extending outwardly from at least one of the opposed sides thereof, the vanes comprising a plurality of spaced apart curved vanes of substantially the same size and shape and disposed in a plurality of circular arrays that are generally concentrically disposed relative to each other about the axis and on the one side of the pulley for acting on fluid adjacent the pulley to tend to cool the pulley with the fluid. The curved vanes in each circular array are each disposed substantially evenly between an adjacent pair of curved vanes in the circular array adjacent thereto whereby the number of the curved vanes in each circular array is the same, each curved vane having a convex side and a concave side. The concave side of each curved vane faces the axis and is substantially symmetric about a radial line intersecting its midpoint and the convex side of each curved vane faces in the direction of the peripheral groove.
