A Planetary Gearbox has a central Sun Gear is surrounded by three of four Planet Gears. These are all held together through an outer ring gear with internal teeth.
This design spreads the power equally through the gears and enables a Planetary Gear System to achieve a high torque in a small space. Planetary Gear Boxes are known for their high endurance and accuracy.
A simple planetary gear set is made up of three main components:
(1)The sun gear that sits in the centre (central gear). (2)Multiple planet gears. (3)The ring gear (outer gear).
The three components make up a stage within a planetary gearbox. For higher ratios we can offer double or triple stages.
