ABSTRACT:
In a power transmission chain comprising multiple rows of link plates, leaf spring links, interposed between adjacent link plates, provide the chain with a degree of resistance to bending and thereby reduce vibration noise. The leaf spring links are provided with sprocket tooth-contacting surfaces which extend a short distance beyond the opposite sprocket tooth-contacting surfaces of the adjacent link plates. Consequently, the leaf spring links, perform two functions. They not only reduce vibration of the chain, but also cushion the impact of the sprocket teeth with the tooth-contacting surfaces of the link plates of the chain, thereby reducing impact noise. The leaf spring links can be arranged in two rows in overlapping, longitudinally offset relationship.
