17 PULLEY WITH HUB CONSTRUCTION OF TWO AXIAL PARTS Abstract of the Disclosure A pulley (40,140,240) having an axially extending annular belt engaging wall construction (42,142,242) including an axial wall portion (44,144, 146,244,246) formed of sheet metal. The sheet metal also forms a circular wall portion (52,152,252) integral at one end with the axial wall portion and extending radially inwardly and axially inwardly with respect to the one end of the axial wall portion. The circular wall portion has an annular bend (54,154,254) in an intermediate annular area thereof and extends therefrom radially inwardly and axially outwardly to a hub construction (56,156,256). The hub construction is formed of first and second axial parts. The first part is formed integrally from the sheet metal into a cylindrical wall structure (58,158,258) extending axially inwardly from the circular wall portion. The second part (60,160,260) is made of sheet metal to include a cylindrical wall portion (64,164,264) having an annular flange (66,166,266) extending therefrom rigidly fixed to the circular wall portion. The cylindrical wall structure and portion include aligned interior cylindrical shaft engaging surfaces (68,168,268). The axially outward end of the cylindrical wall portion provides an integral radially outwardly extending annular lip (70, 174,278) suitable to be operatively engaged by a pulling tool for removing the interior cylindrical surface from engagement with a shaft on which it has been engaged.
