ABSTRACT:
A one-piece sintered pulley hub construction formed of powder metal is provided with a pair of radially outwardly extending hub pulling flanges. The hub has a generally tubular-shaped body with front and rear end faces and a cylindrical bore extending axially therebetween. The pulling flanges are formed integrally with the tubular body and extend radially outwardly from adjacent the front end of the tubular body in diametrically opposite directions, with the front surfaces of the flanges preferably lying in the same plane with the front end face of the tubular body. The flanges provide lugs for gripping by a hub pulling device and they enable the hub to be formed in one piece by a powder metal sintering process eliminating costly machining procedures.
