What is the difference between a planetary reducer and a gear reducer?

1. Planetary reducer, composed of a solar gear system plus a group of multiple groups of planetary wheels (a group of three), can maintain quite high accuracy in the process of telling operation, and relative to its output torque, the volume of planetary reducer is very small.
Single section can do 1/10, through modular design, speed ratio can reach 1000, or even more than 1000.
But because of the precision of its materials, the processing method is meticulous, so the cost of planetary reducer is much higher than that of gear reducer.

2, gear reducer, single section can do 1/200, through modular installation and achieve a higher speed ratio of 1/2000, this kind of reducer, smooth operation, small noise, and the market price is low, more used for all kinds of low load assembly line installation.
Compared to the planet, the gear reducer can not improve the accuracy, and the torque is impossible to reach the height of the planet.
