Latest Patents

Kazufumi Kotani's latest patents include a rocker joint pin type silent chain and a silent chain. The rocker joint pin type silent chain features link plates with two different engagement pitches. The connecting pins consist of combinations of rocker pins and joint pins, with each rocker pin having one of two thicknesses and each joint pin having one of two thicknesses. This design allows the rocker joint pins of the chain to have three different thicknesses, with the link plates and connecting pins arranged randomly along the length of the chain. The silent chain, on the other hand, is composed of interleaved rows of link plates held by connecting pins secured to guide plates along the sides of the chain. The guide plates are formed with protrusions and are deformed to exert a spring action on the rows of link plates, pressing them against one another to increase frictional contact and reduce vibration and noise.
