The Dry Continuously Variable Transmission (CVT) consists of a driving pulley and a driven pulley joined by a rubber V-belt. An each pulley consists of a fixed flange and a movable flange. The movable flange of the driving pulley has the centrifugal roller and a ramp plate in the flange. The movable flange moves toward a fixed flange under the actuation of a centrifugal roller, as the driving pulley speed increases. In this study, the function and the relationship of the all parts in the Dry CVT are investigated. The profile of movable flange is analyzed. The effect of axial force is also analyzed by speed ratio and load torque.
