Abstract: A simple-structured, easy-to-produce chain drive mechanism is provided, which can reduce the overall noise level irrespective of chain length or rpm, while suppressing noise and vibration caused by tension fluctuations and maintaining durability and service life. The engagement/seating mode between a silent chain and a driving sprocket is one of inside-flank engagement/inside-flank seating, inside-flank engagement/outside-flank seating, outside-flank engagement/inside-flank seating, and outside-flank engagement/outside-flank seating. The engagement/seating mode between the silent chain and a driven sprocket is one of inside-flank engagement/inside-flank seating, inside-flank engagement/outside-flank seating, outside-flank engagement/inside-flank seating, and outside-flank engagement/outside-flank seating. The engagement/seating mode between the chain and the driving sprocket is different from that between the chain and the driven sprocket.

Abstract: Provided is a chain power transmission mechanism and a silent chain each having a simple configuration, easy to manufacture, and capable of reducing noise in the entire chain power transmission mechanism. Link plates of the silent chain include an inner-flank-engagement link plate which engages with a sprocket in an inner flank engagement mode and an outer-flank-engagement link plate which engages with the sprocket in an outer flank engagement mode. The inner-flank-engagement link plate and the outer-flank-engagement link plate are arranged such that combinations of the link plates at positions where engagement with and disengagement from a plurality of the sprockets are synchronized include a combination in which at least one of the link plates is different in engagement mode from another link plate.
