Composition: belt drive belt pulley 1, a driven belt wheel 2, a driving belt 3 and frame. 2 working principle: when the driving wheel rotates, the belt and the belt wheel between the work surface friction or engagement, driving wheels are driven to rotate and transfer power. 3 to improve the transmission ability of measures:, N, alpha (angle) 4 transmission ratio: i=n1/n2=D2/D1
