Abstract
A silent chain power transmitting apparatus has an endless link chain having a plurality of link plates (A,B,C, . . . ) connected together, and sprocket wheels (). Each of an inside flank () and an outside flank () of each link plate (A,B,C, . . . ) is profiled by a circular shape of a same radius (ρ) of curvature whose individual center (d, . . . ) of curvature is on a chain pitch line (PL). Each tooth () of the sprocket wheel () is profiled by a circular shape of the same radius(ρ) of curvature, which is meshed with corresponding inside flank () and outside flank () of each link plate (A,B,C, . . . ). A power of the sprocket wheel () is transmitted to the link plates (A,B,C, . . . ) in linear contact (or surface contact) momentarily, not in point contact.
