Abstract

A worm and worm gear decelerating mechanism comprises a driving mechanism, a first worm and worm gear transmission mechanism connected with the driving mechanism, and a second worm and worm gear transmission mechanism. The decelerating mechanism is a double-stage progressive worm and worm gear decelerating mechanism. Large speed reduction ratio and low noise are realized by the first worm and worm gear transmission mechanism. High torque transmission and low noise are realized by the second worm and worm gear transmission mechanism. The power transmitted by a driving motor is decomposed by the first worm and worm gear transmission mechanism to a first worm gear and a second worm gear via a first driving worm, and then further delivered to a first transmission worm and a second transmission worm of the second worm and worm gear transmission mechanism. The driving force of the driving motor is delivered to a third worm gear by the first transmission worm and the second transmission worm and finally output by an output mechanism. The decelerating mechanism reduces the impact force of the driving motor and efficiently reduces noise. By double-stage transmission decomposition, the travel is prolonged, the rotating speed is reduced, and the torque and speed reduction ratio are efficiently improved.

Description

technical field [0001] The invention relates to a transmission device, in particular to a worm gear reduction mechanism. Background technique [0002] The worm gear reduction mechanism is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor (motor) to the desired number of revolutions and obtain a larger torque mechanism. Among the mechanisms currently used to transmit power and motion, the application range of reduction mechanisms is quite wide. [0003] The basic structure of the worm gear reduction mechanism is mainly composed of transmission parts worm gear, shaft, bearing, driving mechanism and output mechanism. The main function of the worm gear is to transmit the motion and power between the two interlaced shafts, and the main function of the bearing and the shaft is to transmit power, run and improve efficiency. [0004] The problems existing in the prior art are: the direct drive transmission, th...
