Abstract
A silent chain and sprocket for power transmission includes a silent chain formed of interleaved rows of multiple link plates and a sprocket used with the silent chain. Each of the teeth of the chain links is formed of an outside flank and an inside flank, and a protrusion is formed on the outside flank in the vicinity of the aperture. At the onset of meshing with the sprocket, the inside flanks of the link plates of the link rows contact the sprocket teeth. As engagement proceeds, the points of engagement of the links with the sprocket teeth are transferred from the inside flanks of the links of a first row to the outside flanks of the links of the preceding adjacent row, and the chain is seated on the outside flanks of the links. The point of projection of the engagement endpoint on the inside flank onto the outside flank coincides with the engagement transfer point on the outside flank or is in the vicinity of the engagement transfer point.
