Cylindrical gear reducer is a power transmission mechanism, which uses the speed converter of the gear to reduce the number of revolutions of the motor to the required number of revolutions, and obtains a large torque mechanism. Cylindrical gear reducers are generally used for low speed and high torque. The power of the motor, internal combustion engine or other high-speed operation is achieved by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft to achieve the purpose of deceleration. Ordinary cylindrical gear reducers will also have several pairs of The gears of the same principle achieve the ideal deceleration effect, and the ratio of the number of teeth of the large and small gears is the transmission ratio.
A gear transmission in which the axis of one or more gears revolves around the fixed axis of another gear is the principle of a planetary reducer.Planetary gear reducer, cycloid reducer, worm gear reducer, planetary friction type mechanical continuously variable transmission and so on.
