BELT DRIVE PULLEY WITH A NON-INTEGRALLY FORMED CENTERING FLANGE

摘要

A pulley for use with a belt drive, the drive belt comprising a plurality of longitudinally spaced inner lugs each having an alignment groove dividing each lug into first and second segments. The pulley comprises a circular frame configured to rotate about a rotation axis. A plurality of circumferential teeth extend radially and axially of a peripheral edge of the circular frame. Each tooth is configured to be received between adjacent inner lugs of the drive belt. A tooth groove is provided in each of the teeth. The tooth groove is configured to align with the alignment groove of the drive belt. A circular alignment flange formed separately from the circumferential teeth is received in the tooth grove of each tooth. With the circular alignment flange received in the tooth groove of each tooth, the alignment flange is received in the alignment groove of a drive belt operatively associated therewith.
