Abstract:
A silent chain power transmitting device including a sprocket and a silent chain trained around the sprocket so as to provide a tension run and a slack run on opposite sides of said sprocket when the chain is traveling around the sprocket under load, wherein the tension run of the silent chain has a chain pitch which varies in dependence or the load in the tension run, and the value of the chordal pitch of the sprocket is such that the chain pitch of the tension run of said silent chain becomes substantially equal to the value of the chordal pitch of the sprocket while the silent chain power transmitting device is operating with said tension run under load, and wherein the value of said chordal pitch of the sprocket has a dimensional tolerance, and the difference between said chain pitch of the tension run of the silent chain and said chordal pitch of the sprocket is within said dimensional tolerance of the chordal pitch of the sprocket.
