ABSTRACT:
A one piece sheet metal pulley has a support structure for rigidly affixing the pulley to an end of a rotary shaft. The pulley includes a peripheral surface, a web, and a hub integrally formed of a single metal sheet. A plurality of protrusions are raised from the hub, each protrusion being a portion between two spaced slits bent upwards to hold the shaft end. The bent-up portion is contiguous with the sheet metal hub at opposite ends of the slits and is raised axially from the hub intermediate the ends, the protrusions bearing radially against the shaft adjacent the shaft end. A bolt hole is centrally provided in the hub for inserting an axial bolt through the hub and into the shaft, and a rotation preventing means having an eccentric attachment means on the hub resists relative rotation.
