Abstract
A composite gear member and gear set using the composite gear member is provided. The composite gear member is formed of a generally circular disk having a pair of link plate supporting surfaces separated by a central section. A roller chain which includes a plurality of rollers rotatably mounted on support pins extends between link plates. The chain is reeved around the disk with the link plates being supported in the grooves on the link plate supporting surfaces. Retaining devices in the form of retaining plates or pins are connected between the chain and the disk to restrain circumferential movement of the chain with respect to the disk. This also prevents circumferential slipping of the chain. If the mounting of the chain on the disk is by a retaining plate device engaging the link plate, a single strand of chain is utilized to form the entire gear member, with the second toothed gear being arranged to drivingly engage the rollers. If pins are utilized extending between certain of the rollers, a double or other multiple-strand chain is utilized with one strand engaging the disk and the other strand or strands being available to engage a toothed gear. With this arrangement, the toothed gear can engage the second strand, either internally or externally.
