Abstract
A method of constructing a pulley comprising a shaft, annular members and a rim, wherein the shaft has an integral tapered surface of a uniform slope near each end. The annular members have an interior periphery of a slightly larger diameter than the outside diameter of the shaft. The interior periphery of the annular members also includes a tapered surface with substantially the same slope as the outside diameter of the shaft at its tapered surfaces. In constructing the pulley, the shaft is inserted through the rim. The annular members are then placed over the ends of the shaft and displaced axially toward the tapered surfaces of the shaft until the tapered surface of the annular members are mateably engaged over the tapered surfaces of the shaft. A compressive interference connection is thereby created between the tapered surfaces. A continuous weld is placed all around the outside face of the annular member where the annular member intersects the shaft. A continuous weld is also placed all around the outside face of the annular member where the annular member intersects the interior periphery of the rim.
