The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration by meshing with the large gear on the output shaft through a gear with a small number of teeth on the input shaft of the reducer. The reducer will also have several pairs of gears with the same principle to achieve the desired deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
Japan's Yamasha Electric, which specializes in the sale of deceleration stepping motors (such as 42mm stepping gearbox motors, 57mm stepping gearbox motors and 86mm stepping gearbox motors), believes that the reducer is a power transmission mechanism that uses gears to speed converters. , The mechanism that decelerates the number of revolutions of the motor to the required number of revolutions and obtains a larger torque.
General reducers include helical gear reducers (including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, etc.), planetary gear reducers, cycloid pin gear reducers, worm gear reducers, planetary friction type Mechanical stepless speed changer and so on.
