Abstract
A moldable, plastic idler pulley is formed of two halves, each having a matching central hub and a radially outwardly extending web with radially disposed strengthening ribs on the outside thereof. The inner side of each central hub has a moldable stepped portion which closely mates the other hub. The stepped portions of each hub and the ribs have no under cuts or reverse bends and may be molded by two simple, axially parting mold elements. After molding, the ribs cooperate with a rotary machine to allow the stepped portions of each hub to be spin welded together. A central bearing may be captured between the hubs during the welding process, if desired.
