The reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor (motor) to the required number of revolutions and obtain a larger torque. Among the mechanisms currently used to transmit power and motion, the application range of the reducer is quite wide. Traces of it can be seen in almost all kinds of mechanical transmission systems, from ships, cars, locomotives, etc. Heavy machinery used in construction, processing machinery and automated production equipment used in the machinery industry, to common household appliances, clocks, etc. in daily life. The application of reducers can be seen in the transmission of large power, to small loads, precise angle transmission, and in industrial applications, reducers have the function of decelerating and increasing torque. Therefore, they are widely used in the classification of speed and torque conversion equipment.: "Comprehensive Standard Samples of Reducers" included in the product catalog Planetary Cycloidal
