Abstract
The utility model relates to a worm and gear reducing mechanism which comprises a driving mechanism, a first worm and gear transmission mechanism and a second worm and gear transmission mechanism connected with the driving mechanism. According to the mechanism provided by the utility model, a two-stage progressive worm and gear reducing mechanism is adopted, and a large speed ratio and low noise are realized through the first worm and gear transmission mechanism, and large torque transmission and small noise are realized through the second worm and gear transmission mechanism. The first worm and gear transmission mechanism decomposes power transmitted by a driving motor through a first driving worm to a first worm and a second worm. Then, the power is further transferred to a first transmission worm and a second transmission worm of the second worm and gear transmission mechanism. The first and second transmission worms transfer the transmission force brought by the driving motor to a third worm and the transmission force is finally output by an output mechanism, so that the impact brought by the driving motor is reduced, and the noise is effectively reduced. Through second-stage transmission and decomposition, the stroke is prolonged, the rotating speed is reduced, and the torque and speed ratio are effectively improved.
