ABSTRACT:
A unidirectional roller chain system for use primarily in automotive engine camshaft drive applications wherein the tooth profile of the sprockets are modified for noise reduction. This new tooth profile is asymmetrical with flank radii that may differ from the drive side to the coast side of the tooth. This configuration lowers the overall noise level of the chain drive system by reducing the engagement impact energy as the sprocket collects a roller from the span, and maintaining the chain rollers in hard contact with the root surface in the sprocket wrap.
