Abstract
Retaining clamps for retaining an over-molded plastic component to a substrate are disclosed herein that include a generally annular band having an inner surface, which defines an inner cavity for receiving a substrate rotatable about a central axis, and an opposing outer surface, which receives an over molded plastic component. The clamps have a plurality of axially extending retaining features formed in the annular band. The retaining features define a trough in the inner surface and a first crest in the outer surface or define a coupling portion forming a second crest. The retaining features are evenly spaced a distance apart along the generally annular band. A pulley body assembly is disclosed having a retaining clamp seated about an outer ring of a bearing for retaining a pulley body over-molded thereto. A method for over-molding a plastic component to a substrate using the retaining clamp is also disclosed herein.
