摘要
A unidirectional roller chain system for use primarily in automotive engine camshaft drive applications wherein the tooth (310) profiles of the sprockets are modified for noise reduction wherein the new tooth (310) profile is asymmetrical with flank radii that may differ from the drive side to the coast side of the tooth (310). This configuration lowers the overall noise level of the chain drive system by reducing the engagement impact energy as the sprocket (300) collects a roller (90) from the span and maintains it in hard contact with the root surface in the sprocket wrap.
