Variable speed principle of V-shaped packaging steel belt continuously variable transmission device
　　 When the V-shaped steel belt continuously variable transmission device shifts, the distance between the main and driven pulley shafts remains unchanged, and the moving cone of the main and driven pulleys move relative to the fixed cone. The movement of the moving cone is usually completed by a hydraulic device. When the moving cone of the driving pulley approaches its fixed cone, the moving cone of the driven pulley moves in the direction away from the fixed cone correspondingly. This movement will cause the V-shaped steel belt to translate as a whole, and change the diameter of the contact friction circle between the main and driven pulleys and the V-shaped steel belt. The driving radius of the driving pulley will increase, and the driving radius of the driven pulley will decrease. , Thus the transmission ratio becomes smaller. On the contrary, when the moving cone of the driven pulley is close to its fixed cone, the moving cone of the driving pulley will move in the direction away from the fixed cone correspondingly, and the transmission ratio will increase. Since the transmission radius of the driving and driven pulleys can be continuously changed within a certain range, the device can realize a continuously variable transmission with a continuously changing transmission ratio.
