Abstract
In a chain transmission, the link plates of a roller chain or rollerless bushing chain are formed with pairs of teeth. A sprocket has a central set of sprocket teeth for meshing with the rollers or bushings, and sets of side sprocket teeth for meshing with the teeth of the link plates. The teeth of the link plates function as a silent chain. After an inner flank of a link plate tooth comes into contact with a side sprocket tooth, a roller and an outer flank of the link plate tooth are seated on the sprocket.
