ABSTRACT:
A belt-driven pulley assembly for an accessory drive includes a steel pulley and a drivebelt sheave made of fiber reinforced phenolic material. The inner surface of the sheave is bonded to the outer surface of the pulley after applying plastic adhesive in a precured condition and inserting the pulley within the sheave. The position of the components are maintained during an elevated temperature polymerization cycle. The thickness of the adhesive is defined by the radial depth of rails extending inward toward the mounting surface of the pulley and by the depth of a stop bead formed on an inclined surface of the sheave that faces the inclined surface of the pulley.
