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.
