The working principle of the planetary reducer is a kind of power transmission mechanism, which makes full use of the speed converter of the transmission gear to reduce the rotation number of the motor to the required rotation number and obtain a relatively large torque. The gear with fewer teeth on the transmission shaft of the planetary reducer meshes with the big gear on the output shaft to achieve the goal of speed reduction. General Reducer There will also be several groups of gears with the same working principle engaged to achieve the ideal speed reduction effect. The ratio of the number of teeth of the size transmission gear is the gear transmission ratio.

Advantages of planetary reducer: small size, light weight, high bearing capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency, safe and reliable performance indicators. It has the characteristics of power distribution and multi tooth meshing.

Defects of the planetary reducer: the planetary reducer has a large gear transmission ratio, and the torque is smaller than other speed reducing mechanisms. The self-locking device of the planetary reducer has a large angle and poor stopping ability, which is not suitable for startup.
