ABSTRACT:
A pulley is provided which is capable of being used as an alternator pulley. The pulley has a central hub portion for connecting the pulley to a shaft and a belt engaging portion disposed radially outward from the central hub portion. The central hub portion and the belt engaging portion are injection molded from a thermoplastic polyphenylene sulfide polymer material. The pulley provides approximately a 75% weight reduction in comparison to conventional metal pulleys used in automotive applications. The pulley is injection molded having a sprue gate located substantially in a center of said central hub portion. A bushing is optionally provided in a center opening in said central hub portion.
