ABSTRACT:
A silent chain transmission mechanism includes a sprocket and a silent chain having link interleaved link rows each composed of plural randomly selected link plates and connected together by connecting pins. The outside dimensions of the link plate are smaller than the outside dimensions of a link, but the outside dimensions of the link match the design reference dimensions of a link plate capable of proper meshing with the sprocket. The requirement for manufacturing accuracy and the effort required for assembly of the silent chain are reduced. However, the silent chain travels on the sprocket on the chain traveling line so that improved noise, vibration and friction properties, and traveling stability are realized.
