Chains can be divided into roller chains, toothed chains and other types according to their structures, among which roller chains are the most widely used. The roller chain consists of inner link plate, outer link plate, pin, sleeve and roller. Among them, the inner link plate and the sleeve, the outer link plate and the pin are connected by interference fits respectively, which are called inner and outer links; the gap fit between the roller and the sleeve, the sleeve and the pin is clearance fit. When the inner and outer chain plates are relatively deflected, the sleeve can rotate freely around the pin. The roller is movable on the sleeve. When working, the roller rolls along the sprocket tooth profile, which can reduce the wear of the gear teeth. .
