Planetary gear reducer

Planetary gear reducer 
The reducer generally converts the input low torque and high speed into a high torque and low speed output through a gear set.The planetary gear reducer has two characteristics. One is that the input shaft and the output shaft are coaxial; the other is that it has more than 3 planetary gears, which provide a larger total torque during speed change, and a more stable speed transmission (always There are gears that mesh well).
