    The main characteristics of the planetary gear transmission are as follows:

1. Small size, small quality, compact structure and large carrying capacity. This is due to the planetary gear box drive with power split and the central wheel constitutes a common axis of transmission and reasonable application of the internal meshing gear.

2. High transmission efficiency. This is because of the symmetry of the structure of the planetary gear drive. Planetary gear box has a plurality of planetary wheels which are known to distribute. The reaction force of the center wheel and the rotating arm can be as balanced, which is beneficial to the improvement of the transmission efficiency. If the selected drive type is appropriate and the structure is reasonable, the efficiency value is 0.97~0.99.

3. Large transmission relatively. The planetary gear box in the transmission ratio is very big, still can keep the structure is compact, small size, small size, etc., and it also can realize the movement of the synthesis and decomposition, and achieve a variety of complex movement. Planetary gears can be achieved by the synthesis and decomposition of motion, as long as the proper selection of the type of planetary gear transmission and the distribution scheme, variable can be used to obtain a large number of gear ratio.

4. Because the planetary gear box uses the same planet wheel, and the uniform distribution in the center wheel, thus can make the planetary wheel and the arm of the force balance, so as to achieve, the planetary gear box at the time of movement stable. At the same time, the number of teeth is increased, so the movement of planetary gear is stable, the ability of resisting impact and vibration is stronger, and the work is more reliable.

Comparing with the ordinary gear drive, the planetary gear box transmission has many unique advantages. Its most notable feature is that it can be carried out when the power is transferred, and the input shaft and output shaft are coaxial, that is, the output shaft and the input shaft are set on the same axis. So the planetary gear box is used to replace the ordinary gear transmission, and as a reducer, speed increaser and variator in variety of mechanical transmission system. Planetary gear box is widely used in many engineering machinery industries, which requairs small size, high quality, compact structure and high transmission efficiency.

Just because planetary gear box has the above advantages, so the planetary gear box transmission has been widely used in various industries. At the same time, the attention of the planetary gear box is not only suitable for high speed and high power, but also has been widely used in the low speed and high torque transmission device. It is because of the planetary gear box that can be applied to all the power and the low speed range, so the current planetary transmission technology has become one of the key technologies of the world.
