Abstract
In a silent chain transmission, noise performance is improved by preventing guide plates of a silent chain from contacting sprocket teeth before the link plates of the chain contact the sprocket teeth. The silent chain transmission comprises a silent chain in engagement with a sprocket. The silent chain comprises guide rows, each having a pair of guide plates and a plurality of middle link plates, and non-guide rows, each having a plurality of inner link plates. An engagement starting point of the middle link plate with a sprocket tooth and an engagement starting point of the inner link plate with the sprocket tooth are set at positions such that the guide plate is prevented from contacting the sprocket tooth before the respective link plates start to engage the sprocket tooth when runout of the chain in the direction of its width occurs.
