Advantages and disadvantages of planetary gear
Sep 03, 2018

Compared with general gear transmission, planetary gear transmission has many unique advantages.

The details are as follows: 


(1) the sun wheel, planet carrier and gear ring are concentric, that is, revolving around the common axis. This can cancel intermediate shaft and intermediate gear such as manual transmission.

(2) All gears always mesh with each other, and there is no need to slip the gear when shifting, so the friction and wear are small and the service life is long.

(3) The planetary reducer features small volume, light weight, compact structure, high transmission power, high bearing capacity, low noise, high output torque, high speed ratio, high efficiency and performance safety. It has the characteristics of power shunt and multi tooth meshing.

(4) The structure is simple and compact, and its load is allocated to a large number of teeth with great strength.

(5) Multiple transmission ratios can be obtained.

(6)The planetary reducer has the ability to move smoothly, resist shock and vibration; the planetary reducer/planetary gear reducer drives smoothly because it uses several identical planetary gears and distributes evenly around the center wheel, so that the inertial force between the planetary gear and the rotating arm can be balanced and the number of teeth involved in meshing increases. stable.



 Because of the complicated structure of planetary gear transmission, it is difficult to manufacture. In addition, due to the compact structure of planetary gears, small space, small heat dissipation area, resulting in faster oil temperature rise, low efficiency.
