摘要

A drive wheel conveyor comprising a tubular side frame (11) extending in a transport direction and having an inner side wall (21), outer side wall (22), top wall (23) and bottom wall (24); a drive shaft (41) supported by the inner (22) and outer side walls (23) so as to extend through the side frame (11), transversely thereof and having an inward projection (49) extending inward through the inner side wall (21); a sprocket (45) fixed to the drive shaft (41) and positioned between the inner (21) and outer side walls (22); an endless drive chain (46) in engagement with the sprocket (45) and disposed inside the side frame (11) so as to be movable in circulation; and a transport wheel (51) having a shaft bore (53) with the inward projection (49) fitted therein and drivable by frictional resistance between the inner periphery of the wheel (51) defining the shaft bore (53)and the outer surface of the inward projection (49). <IMAGE>
