The relative role of the planetary reducer is between the prime mover and the corresponding working machine and the operating mechanism, to play the role of matching speed and transmission torque, planetary reducer is a relatively sophisticated machinery, the purpose of using it is to reduce the speed , Increase the torque. It is a variety of different models, reducer is a relatively sophisticated machinery, the purpose of using it is to reduce the speed, worm reducer and planetary gear reducer; according to the different transmission stages can be divided into single and multi-stage deceleration Machine wheel shape can be divided into cylindrical gear reducer, bevel gear reducer and cone - cylindrical gear reducer.
 
       The reducer is a kind of independent component which is composed of a gear drive, a worm drive and a gear-worm drive enclosed in a rigid shell. It is often used as a deceleration transmission between the original and the corresponding working machine. Planetary reducer is generally used for low-speed high-torque transmission equipment, the motor, internal combustion engine or other high-speed operation of the power through the reducer on the input shaft teeth less gear meshing the output shaft to achieve the purpose of deceleration, Of the reducer will have several pairs of the same principle gear to achieve the desired deceleration effect, the size of the gear ratio of teeth, is the transmission ratio. In the prime mover and the corresponding work machine or operating mechanism between the matching speed and transmission torque role in the modern machinery is widely used.
 
       Planetary reducer different types have different uses. There are many kinds of reducer, according to the type of transmission can be divided into gear reducer, worm reducer and planetary gear reducer; according to the different transmission stages can be divided into single and multi-stage reducer; according to the shape of the gear can be divided into cylindrical gears Gear, bevel gear reducer and conical-cylindrical gear reducer; in accordance with the transmission layout can be divided into expansion, split and coaxial reducer. According to the layout of the transmission can be divided into expansion, split and with the shaft into the reducer.
