Planetary Gearbox

Planetary Gearbox works on Planetary motion principle with various parts and stages.
Accordingly, each stage of the Planetary Gearbox consists of central sun gear meshing.
The gear is accurately positioned with three planet gears around it. The purpose of this is to mesh with the internal teeth of the outer ring gear.
Normally, the Ring gear is stationary and forms the part ofPLANETARY GEARBOX the housing. Therefore the input is given to the Sun gear and output is derived from the three planet gears through a planet carrier.
However, out of these three gears anyone can be held stationary. The second is driven by input and the output can be derived from the third member.
Due to this flexibility, Planetary Gearboxes have a large variety and innumerable applications.
