ABSTRACT:
A pulley comprises a hub and a pair of generally annular sheet metal members having central openings for receiving a portion of the hub and oppositely faltered margins for defining a groove to accommodate a belt. The hub includes a shouder portion of sufficient axial length to extend through the openings of the sheet metal members. A leading end part of the shoulder portion is flared over upon insertion through the openings for grippingly engaging the first and second sheet metal members. A plurality of radially alternating lands and grooves in the hub axially trail the shoulder portion, and a radial array of alternating slots and projections in the first and second sheet metal member openings engage the lands and grooves. Alternatively, a generally annular welding plate is provided having a central opening including a plurality of inward projections for engaging the hub grooves, and a plurality of welding projections for weldable attachment to one of the sheet metal members.
