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: An object of the present invention is to provide a silent chain and a silent chain transmission device which stabilize chain behavior during chain travel to suppress an occurrence of tooth skipping and to reduce a string vibration sound and a meshing noise with simple configurations. In a silent chain 110, a pin hole 161 of an inner plate 160 and a pair of locker pins 170 are configured in such a size that a gap is formed between a seat surface 163 and a back surface of a short pin 172 in a state where the pair of locker pins 170 are in contact with each other on rolling surfaces 171a and 172a.

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.

Abstract: Provided is a silent chain that enables adjustment of the stiffness and balance of stiffness between upper and lower sides of guide plates, and that prevents long pin failure resulting from deflection or torsional deformation while securing a sufficient area and strength for the portion contacting a side face of a sprocket. The guide plate has a lightening hole with an upper end positioned above a pitch line, and a lower end extending out beyond lines that connect intersections between inner side edges of front and rear pin fitting holes and the pitch line, and a midpoint of a lower end edge of the guide plate in a front to back direction. Outermost portions of the lightening hole in a longitudinal direction are formed within a range that does not go beyond a pair of vertical lines vertical to the pitch line passing through the intersections.

Abstract: An object of the present invention is to provide a silent chain which suppresses vibration and undulation while maintaining rigidity, strength, and durability and simplifying a shape of a pin hole without using a locker pin with a special shape and special material. In a silent chain 100, a guide row 101 made up of guide plates 110 and a middle plate 120 and a non-guide row made 103 made up of inner plates 130 are alternately connected in a chain longitudinal direction by a pair of locker pins 140 and 150. Pin holes 121 and 131 respectively have outer peripheral side straight portions 123 and 133 and inner peripheral side straight portions 124 and 134 which are formed parallel to each other.
