    • 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 circular wall portion has an annular bend in an intermediate annular area thereof (54, 154, 254) and extends therefrom generally radially inwardly to a hub construction (56, 156, 256). The entire hub construction is formed integrally from the sheet metal into a cylindrical wall structure (58, 158, 258) extending axially outwardly from the circular wall portion. The cylindrical wall structure has an axial extent greater than the diameter of a shaft engaging interior cylindrical surface thereof (60, 160, 164). The axially outward end of the cylindrical wall structure provides an integral radially outwardly extending annular lip (64, 166, 27) suitable to be operatively engaged by a pulling tool.
    • 具有轴向延伸的环形带接合壁结构(42,142,242)的滑轮(40,140,​​240)包括由金属板形成的轴向壁部分(44,144,146,244,246)。 圆形壁部分在其中间环形区域(54,154,254)中具有环形弯曲部,并从其大致径向向内延伸到毂结构(56,156,256)。 整个轮毂结构从金属板整体形成为从圆形壁部分轴向向外延伸的圆柱形壁结构(58,158,258)。 圆柱形壁结构具有大于其内圆柱形表面(60,160,164)的轴的直径的轴向长度。 圆柱形壁结构的轴向向外端提供适合于通过牵引工具可操作地接合的整体径向向外延伸的环形唇缘(64,166,27)。
