ABSTRACT:
A conveyor sprocket formed of a plastic material is mounted on a keyed drive shaft of circular cross section. Within the hub of the conveyor sprocket, an insert, formed of a relatively harder or more durable material, engages the key. The insert resists deformation and helps increase the torque capacity of the conveyor sprocket. In one embodiment, the keyed shaft includes two diametrically opposed keys and the conveyor sprocket includes two diametrically opposed inserts and engagement therewith. In one embodiment, the key does not project beyond the ends of the conveyor sprocket hub.
