Kinematic Analysis of Chordal Action and Transmission Errors of Silent Chains

This paper investigates the chordal action and transmission errors of a simple silent chain system. The chordal action analysis is based on the tooth contact analysis of the chain with the driving sprocket. Chordal action of different contact patterns is compared. The result indicates that chordal action of the case in which at most two link pates are in contact is significantly reduced. The transmission error analysis is based the tooth contact analysis of the chain with both the driving and driven sprockets. The result shows how the angular motion of the driven sprocket deviates while the driving sprocket rotates at a constant speed.
