Abstract
A silent chain power transmitting device includes a driving sprocket and at least one drive sprocket, and a silent chain stretched over the driving and driven sprockets to provide a tension run and a slack run on opposite sides of the driving sprocket. The driving and driven sprockets have a sprocket pitch (chordal pitch) designed to become substantially equal to a chain pitch of the tension run of the silent chain while operating under load. By thus designing the sprocket pitch relative to the chain pitch, toothed link plates of the silent chain are smoothly guided into sliding contact with teeth of the sprockets without causing objectionable interference or collision. The sprockets and silent chain are substantially free from abnormal wear and hence have an increased degree of durability.
