Planetary

The core factor of an automatic transmission is the epicycloidal or planetary gearset. This type of gearset has the interesting feature of changing gear ratios without having to engage or disengage individual gears. This ensure smooth gear changing even under load and without clutch.

A planetary has three main parts: sun(center gear), planets(small gears turning around the sun), and ring or annulus, that is also engaged with planets by the outer side.
 
In some gearboxes, the planetary carrier of first gearset is connected to second gearset’s ring. They are connected by an axle which is also the output axle of the gearbox to the wheels.

A planetary gear keeps rotating if one part is blocked. Locking different parts makes the gear deliver different gear ratios. It is easier to look the planetary as a ‘black box’, and play with it. 
 
On the basis of those features, planetary gearbox can be used as an original component to produce many products which can be very important in several areas. 
 
Zhaowei company has specialized in micro gearbox for 20 years, to create next miracle through speciality and detail. It is the partner you can trust.
