A worm gear reducer is a power transmission mechanism that uses a speed converter of a gear to reduce the number of revolutions of a motor to a desired number of revolutions and obtain a large torque. In the current mechanisms for transmitting power and motion, the application range of the speed reducer is quite wide. The worm gear speed reducer can be generally divided into three basic structural parts: the box, the worm and gear, the bearing and the shaft are combined. The box body is a base of all accessories in the worm gear speed reducer and is an important accessory for supporting and fixing a shaft system component, ensuring the correct relative position of a transmission accessory and supporting the load acting on the speed reducer. The worm gear and the worm mainly transfer motion and power between the two staggered shafts, and the bearing and the shaft mainly transfer and operate power and improve efficiency. The worm gear speed reducer has lower transmission efficiency and more serious abrasion. When the worm gear and the worm are in meshing transmission, the relative sliding speed between meshing wheel teeth is high, so that the friction loss is high and the efficiency is low. The space utilization rate of the existing common speed reducer box body is very low, when the transmission ratio is larger, the diameter of a worm wheel is larger, the situation that the worm is small in size but occupies a large space often occurs, and the space distribution is unreasonable, so that the waste of space resources and material resources is caused.
