Abstract
A cog-belt-driven power transmission device comprising a belt pulley having a cogging on the outer periphery and a belt having a corresponding cogging on the inner surface. In order to suppress the noise produced during rotation of the belt pulley one or more discharge channels for air entrapped between the coggings are made in the cogging of the belt pulley and/or the belt, said discharge channels connecting the cog gaps to the atmosphere.
