clamp for retaining an overmolded plastic component to a substrate, pulley body assembly and method of manufacturing a pulley body assembly

摘要

retaining brackets for retaining an overmolded plastic component to a substrate, including a generally annular band having an inner surface defining an inner cavity for receiving a rotatable substrate about a central axis, and an opposite outer surface receiving an overmolded plastic component. the clamps have a plurality of axially extending retaining features formed in the annular band. retention characteristics define a groove on the inner surface and a first ridge on the outer surface, or define a coupling portion forming a second ridge. retention characteristics are evenly spaced from each other by a distance along the generally annular band. Also described is a pulley body assembly having a retaining bracket disposed around an outer ring of a bearing for retaining an overmolded pulley body. Further described is a method for overmolding a plastic component to a substrate using the retaining clamp.
