A mechanism with a speed magnifying effect and a torque comparing function comprises a sun gear (1), inner and outer gears (2), planetary gears (3), planetary gear shafts (4) and planetary gear bases (5). The inner and outer gears (2) are coaxially mounted with the sun gear (1). Inner gear rings of the inner and outer gears (2) are meshed with the planetary gears (3). The planetary gears (3) are sleeved on the planetary gear shafts (4). The planetary gears (3) and the inner gear rings of the inner and outer gears (2) are simultaneously meshed with the sun gear (1). The planetary gear shafts (4) are fixed on the planetary gear bases (5). The number of the planetary gears (3) is 2, 3, 4, 5 or 6. The mechanism with a speed magnifying effect and a torque comparing function is greatly simplified, is quick in making a response and is reliable; a simple and convenient basic design is provided, and the mechanism is combined with different control device or additional motion input to implement "a force or torque comparator" and "a speed magnifier"; the mechanism is highly flexible to use; different input ends are selected, and rotation directions of two output ends are coaxial and the same or are coaxial and reverse. |
