Abstract
Noise reduction in a silent chain is achieved by forming the majority of the toothed link plates with modified tooth profiles having a circular concave portion conforming t the shape of the teeth of the sprocket engaged by the chain, and a circular convex portion near the tip, the center of curvature of the convex portion being on the dedendum side of the pitch line. Additional link plates having a different meshing pitch are disposed at irregular intervals along the length of the chain. These additional link plates can have linear of modified tooth profiles.
