In a rocker joint silent chain, the link plates have two different engagement pitches, and the connecting pins are composed of combinations of rocker pins and joint pins, where each rocker pin has one of two thicknesses and each joint pin has one of two thicknesses, so that the rocker joint pins of the chain have three different thicknesses. The link plates and connecting pins are arranged randomly along the length of the chain.

Rocker joint pin type silent chain

In a silent chain composed of interleaved rows of link plates held by connecting pins secured to guide plates disposed along the sides of the chain, the guide plates are formed with protrusions, and are deformed so that they exert a spring action on the rows of link plates through the protrusions, pressing the link plates against one another to increase the frictional contact between the link plates, and thereby reduce vibration and vibration noise.
