small planetary gearbox

A planetary gearbox identifies a gear system in which a number of ‘world’ gears rotate around a central ‘sun’ gear. Typically, a world carrier is powered by the input torque which rotates the planets around a set outer ring (sometimes referred to as the annulus). Therefore drives sunlight gear which then provides the output torque. Nevertheless there are examples of the various other combinations, such as the sun gear being fixed and the band providing output torque.

The main benefit of planetary gearboxes are their high power transmission efficiencies. Typicially this could be around just 3% per stage. Further to the, the high effiency is usually delivered regardless of the compact design giving a sizable torque to size/weight ratio. A few of this is thanks to the load sharing that occurs across the multiple planet gears.
