Abstract
A chain and sprocket drive system that includes a sprocket and an inverted tooth chain assembly configured to mesh with the sprocket is provided. The chain assembly includes at least two rows of links, each of the links having teeth with a pair of inner flanks, a pair of outer flanks, tips interconnecting a respective inner flank and outer flank, and a radiused crotch located between the pair of inner flanks. The inner flanks have an enlarged profile in a direction toward a center of the link in comparison to a profile of the outer flanks. A contact position with a tooth of the sprocket engaged therewith is located on the link in an area extending from the inner flank into the radiused crotch and on the sprocket in an area of the radiused tip of the tooth.
