Worm gear reducer is a kind of power transmission mechanism, which uses the speed converter of gear to reduce the rotation number of motor (motor) to the required number of revolutions and obtain a large torque.
The basic structure of worm gear reducer is mainly composed of transmission parts, worm gear, shaft, bearing, box and its accessories. It can be divided into three basic structural parts: box, worm gear and worm, bearing and shaft combination. The box is the base of all accessories in the worm gear reducer. It is an important accessory to support and fix the shafting components, ensure the correct relative position of the transmission accessories and support the load acting on the reducer.
The worm gear is mainly used to transmit the motion and power between the two staggered shafts, and the bearing and shaft are mainly used to transmit power, operate and improve efficiency.
Therefore, worm gear reducers are generally used for transmission equipment with low speed and high torque. The power of motor, internal combustion engine or other high-speed operation is meshed with the large gear on the output shaft through the gear with less teeth on the input shaft of the reducer. Ordinary reducers also have several pairs of gears with the same principle to achieve ideal deceleration effect. The ratio of the number of teeth of large and small gears, Is the transmission ratio.
