High-performance silent chain

a silent chain, high-performance technology, applied in the direction of chain elements, gearing control, gearing elements, etc., can solve the problems of reducing the bearing surface area, increasing the width of each strand of chain, and inherently requiring more elaborate manufacturing procedures to produce chain links, so as to achieve the effect of increasing the width of the first link

Abstract

A hybrid roller / silent chain of the present invention has the wear resistance of a roller chain combined with the noise performance of a silent chain. This is accomplished with the use of transverse load-bearing elements that allow increased bearing area for the articulating members of the chain by allowing load to be transmitted through both the inside and outside diameter of the element in the same plane. In some embodiments, the transverse load-bearing elements are bushings. In other embodiments, the elements are projections extending from non-guide row inside links.
