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 either in a direction toward the other flange or in a direction away from the other flange and has a fluid dampening unit separate from the structure for moving and being operatively associated with the one flange to dampen the axial movement of that one flange in either of the directions relative to the other flange with a restrictive force, the dampening unit comprising a flexible bladder having one part thereof operatively interconnected to that one flange.
