Sprocket 23TB25mm08BChainCDM Autowrap As a chain engages and disengages with a sprocket there is a rise and fall of each link and a velocity variation These are due to chordal action caused by the chain forming a polygon on the sprocket In the diagrams below as Roller B approaches the sprocket it follows the chordal line of Roller A Once engaged it is caused to rise following the arc of the pitch circle As the chain unwraps from the sprocket the reverse occurs As well as inducing a vibration into the chain the linear velocity of the chain is varied from a minimum on effective radius d to a maximum on the pitch circle radius r The level of this cyclic speed variation can be determined
