This invention relates to a universal mechanical variable-speed box composed of planetary system and tooth-sleeve clutch. By changing the engaging conditions between planetary system and tooth-sleeve clutch, four-step speed variation can be realized. Compared with existing gear box, it features high drive ratio, high load power, simple structure and low cost. It can be widely used as the decelerating or speed-varying drive of various mechanical apparatuses. |
