Reducer is a relatively precise machinery, the use of its purpose is to reduce the speed and increase torque. In some places are also used to speed up, known as the speed regulator. Generally used for low speed large torque transmission equipment, the large gear output shaft gear meshing power motor, internal combustion engine or other high speed running through the reducer input shaft less number of teeth on the reducer to achieve the purpose of ordinary reducer will have several of the same principle to achieve the desired reduction gear effect, the size of the gear than the number of teeth of the gear ratio is.
Reducer category, variety, type of many, has been developed for the line (country) of the speed reducer has more than 40 kinds. Reducer category is according to the use of gear tooth and tooth profile curve division; reducer reducer variety is designed according to the structural differences of need; type of reducer reducer difference characteristic based on the basic structure of the tooth surface hardness, transmission series, shaft type, assembly type, installation type, connection type factors and design.
Speed reducer, motor output speed ratio = output rotation ("speed" also known as "the transmission ratio of 1) know the motor power and speed ratio and the coefficient for the following formula: torque reducer, reducer torque motor, motor power =9550 * * * power input speed ratio by a factor of 2 known torque and output speed reducer and use coefficient for the required motor power reducer with the following formula: = 9550 * motor power / torque motor power input speed, speed ratio, using the coefficients of species variety, different models, different types have different uses.
There are many types of reducer according to transmission type can be divided into gear reducer, worm gear reducer and planetary gear reducer; according to transmission series can be divided into single and multi-stage gear reducer; according to the shape can be divided into cylindrical gear reducer, bevel gear reducer and cone - cylindrical gear reducer; according to the arrangement of transmission can be divided into expansion, split and coaxial reducer. The following is the commonly used reducer classification:
1, cycloid reducer 2, hardened cylindrical gear reducer, planetary gear reducer, 3. 4, soft tooth surface reducer 5, three ring gear reducer 6, crane reducer, worm gear reducer 8, hardened gear reducer 9, CVT
