Abstract
A pulley construction and method of making the same are provided, the pulley construction having a pair of opposed flanges respectively provided with surfaces for engagement with a V-belt construction when the V-belt construction is disposed therebetween. The pulley construction has a speed responsive unit for moving one of the flanges axially relative to the other of the flanges, the speed responsive unit comprising a pair of opposed raceways respectively having surfaces and movable elements disposed against the surfaces of the raceways for movement in the raceways. The surfaces of the raceways comprise polymeric material that will be deflected by the movable elements and thereby will tend to dampen out vibrations and shock load motion as the movable elements move relative to the surfaces of the raceways.
