摘要

A rocker joint silent chain, the link plates 110A 7 110B have two different engagement pitches P1 and P2, and the connecting pins are composed of combinations of rocker pins 121 and joint pins 122, where each rocker pin has one of two thicknesses t1, t2 and each joint pin has one of two thicknesses t1, t2, so that the rocker joint pins of the chain have three different thicknesses, fig 4a-c. The link plates 110A and 110B and connecting pins are arranged randomly along the length of the chain 100. The chain significantly reduces periodic engagement noise.
