Abstract
A chain and sprocket drive system that includes an inverted tooth chain assembly configured to mesh with a laminated sprocket assembly is provided. The inverted tooth chain assembly includes a plurality of rows of links. The laminated sprocket assembly includes a plurality of plates, each of the plates including a plurality of teeth that are aligned with adjacent teeth. Each tooth has an engaging flank and a disengaging flank. The engaging flank of the teeth on one of the plurality of plates has an enlarged profile in a radially outwardly extending direction in comparison to corresponding ones of the teeth of an adjacent one of the plates, such that a first contact position with a link of the chain assembly carried thereon is located radially outward from a second contact position of the link with the corresponding teeth of the adjacent one of the plurality of plates.
