Deceleration machine General for low speed big torque of drive equipment, put motor. engine or other high-speed running of power through deceleration machine of entered axis Shang of tooth number less of gear meshing output axis Shang of big gear to reached deceleration of purpose, General of deceleration machine also will has several on same principle gear reached ideal of deceleration effect, size gear of tooth number of than, is ratio.
Speed reducer is a relatively sophisticated machinery, its purpose is to reduce the speed, increase the torque. Its wide range of different models, different species have different uses. A wide variety of gear reducer, according to the type of transmission can be divided into gear reducers, worm gear reducer, and planetary gear reducers according to power series can be divided into single-stage and multistage gearbox; according to the gear can be divided into cylindrical gear reducer, bevel gear reducers and conical-cylindrical gear reducer; follow the layout can be divided into transmission expansion, split and coaxial reducer.
