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 structure for moving one of the flanges axially relative to the other of the flanges and has a fluid dampening unit operatively associated with the one flange to dampen the axial movement of that one flange relative to the other flange with a restrictive force, the dampening unit comprising a flexible bladder having a part thereof operatively interconnected to that one flange.
