Planetary Gearbox Special Features 


Due to the nature of the design, the planetary gear system excels at load distribution. Whereas in a traditional gear system it relies upon the movement and transmission between small and large gears, this is not the case in the planetary gear system.

In the planetary gear system the load is distributed throughout the planet gears. In this way issues such as broken gear teeth which occur in traditional systems when under heavy loading, do not occur frequently within a planetary gear set.



A planetary gearbox is a gearbox with the input shaft and the output shaft aligned. A planetary gearbox is used to transfer the largest torque in the most compact form (known as torque density).

The bicycle’s acceleration hub is a great example of a planet-wheel mechanism: Have you ever wondered how you can get so much power and capabilities in such a little hub? For a three-speed hub, a one-stage planetary gear system is used, for a five-speed hub a 2-stage. Each planet gear system has a reduction state, a direct coupling and an acceleration mode.

Whoever invented the planetary gearbox is not known, but was functionally described by Leonardo da Vinci in 1490 and has been used for centuries.

TRANS AB series planetary gearbox is the most popular servo gearbox. With helical gears and integrated output planetary carrier,TRANS AB series planetary gearboxes have played the advantages of high precision, low noise, and high efficiency up to 95%.

CHE launched the high-speed gear end of the supoort and the integration process, to achieve better concentricity requirements to meet the low noise requirements; increasing the reducer adjustment ring, adjust the internal axial clearance, ran achievement
minimization; reducer output end of the tapered roller bearing load, the force to meet the greater demand and absolute stability after loading.

The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration by meshing with the large gear on the output shaft through a gear with a small number of teeth on the input shaft of the reducer. The reducer will also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
