Reducer is a wide variety, according to the type of transmission can be divided into gear reducer, worm reducer and planetary gear reducer; According to the different transmission series can be divided into single-stage and multi-stage reducer; According to the gear shape can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical gear reducer, according to the layout of the transmission can be divided into expansion type, shunt and coaxial reducer.

Reducer is a power transmission mechanism, Reducer the use of gear speed converter, the motor (motor) to reduce the number of rotation to the number of rotation, and get a larger torque mechanism. At present, the application scope of the reducer is quite extensive in the mechanism of transmission power and motion. In almost all kinds of mechanical transmission system can see its traces, from the transport of ships, automobiles, locomotives, Reducer construction of heavy machinery, machinery industry used in the processing machinery and automated production equipment, to daily life common household appliances, clocks and so on. Its application from the transmission of large power, to small load, accurate angle transmission can see the application of reducer, and in industrial applications, Reducer reducer has deceleration and increase torque function. Therefore it is widely used in speed and torque conversion equipment. The main role of the Reducer is: spin down at the same time increase the output torque, torque output ratio according to motor output by deceleration ratio, but to pay attention to can not exceed the rated torque reducer.

Deceleration reduces the inertia of the load and reduces the inertia to the square of the deceleration ratio. You can look at the general motor has a value of inertia.

Use and maintenance of reducer

Before the reducer is formally used, it must carry out load test. 1 before the load test should be according to the oil standard position to add lubricating oil, rotate with the hand, so that the output shaft rotation one weeks, must be flexible, then empty operation two hours, Reducer should be normal noise. 2 load test should be gradually loaded to full load (when conditions should be 25%, 50%, 75%, 100%, four stages of loading, each stage of operation time is not less than 2 hours, should be smooth without impact vibration and oil leakage, Reducer to ensure that no fault after the machine will be put out of lubricating oil or 200 mesh filter will be used to filter the oil. 3 reducer operation should be repaired once a year, after the regular (weekly) inspection of tooth surface oil pitting, abrasions, gluing defects, if the defect area along the tooth length and tooth height direction of more than 20%, and continue to develop the gear pair should be replaced. First, reducer working principle reducer of a wide range of models, different types have different uses. Reducer types, according to the type of transmission can be divided into gear reducer, worm reducer and planetary gear reducer; According to the transmission series different classes are divided into single-stage and multistage reducer, bevel gear reducer and conical-cylindrical gear reducer, according to the layout of the transmission can be divided into expansion type, shunt type and coaxial type reducer.
