Worm gear reducer is a power transmission mechanism, the use of gear speed converter, the motor rotation number to slow down to the desired number of rotation, and get a larger torque mechanism. At present, in the mechanism used to transmit power and motion, the application range of speed reducer is quite wide.

The trace of the reducer can be seen in the transmission system of all kinds of machinery, from ships, automobiles, locomotives, heavy machinery for construction, processing machinery and automatic production equipment used in the machinery industry, to common household appliances in daily life, clocks and so on. The application of the reducer can be seen from the transmission work of large power to the precise angular transmission of small loads, and in industrial applications, the reducer has the function of slowing down and increasing torque. Therefore, it is widely used in speed and torque conversion equipment.
