Chain assembly with flat links of extended horizontal length

摘要

A phased chain and sprocket assembly is provided in which the pitch length of the chain is not matched to the pitch length of the sprocket. Specifically, the chain link pitch length is approximately twice the pitch length of the associated sprocket teeth. By providing two chains in side-by-side, but offset relation, a phased chain and sprocket assembly can be achieved without the need for circumferentially offset sprockets.
