Abstract:
1. A double-sided driving silent chain, comprising an endless assembly of double-sided driving link plates and pins, each link plate having a pair of teeth on both sides thereof and the pins alternately linking the link plates, the double-sided driving link plate being formed such that a crotch between the pair of teeth of another side is shallower than a crotch between the pair of teeth of one side and a distance from a center line connecting a pair of pin holes to a bottom of the crotch of the other side being equal to or greater than a half of a diameter of the pin hole, the double-sided driving link plate being formed such that upper and lower parts thereof are asymmetrical about the center line, edges of the pair of teeth of the one side being substantially curved and edges of the pair of teeth of the other side being formed completely as flat surfaces that are parallel to the center line, the pair of teeth of the one side and the pair of teeth of the other side each comprise inner flanks and outer flanks each forming respectively same sprocket engagement mechanisms, and a height of the pair of teeth of the other side is shorter than a height of the pair of teeth of the one side when measured from a base of the crotch of the respective other and one sides, intersections of outer flanks formed on an outer side of the pair of teeth of the one side of the double-sided driving link plate with outer flanks formed on an outer side of the pair of teeth of the other side are disposed on the side of the other side and spaced from an extension of the center line, and the double-sided driving silent chain has relationships of: where h is a distance from the center line to a bottom of the crotch of the one side, H is the distance from the center line to the bottom of the crotch of the other side and D is the diameter of the pin hole.
