PG42A-PM-ST Powder Metallurgy Split Straight Teeth Planetary Reducer Gearbox 42mm
PG42A-PM-ST Powder Metallurgy 42mm dia Split Straight Teeth Planetary Reducer Gearbox
The planetary reducer gearbox is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque mechanism. The gear with a small number of teeth on the transmission shaft of the planetary reducer meshes with the large gear on the output shaft to achieve the purpose of deceleration. Ordinary reducers also have several pairs of gears meshing with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
