A new approach to overcome and eliminate the polygon effect in chain drives is discussed in this paper. Tooth shape of chain drive in parallel motion is determined by the envelope theory. Sprocket and chain turn together on the last point of their line of action to realize chain transmission with constant pitch or with non-constant pitch, The article puts forward a new method, "envelope-path" method, to correct the tooth shape mentioned. During the chain transmission the former joint moves along circular are, the latter has a parallel motion in order to eliminate fully the polygon effect of chain drives. Finally the article introduces several circumstances which affect the design of chain drives.
