A planetary gearbox identifies a gear system in which a number of ‘planet’ gears rotate around a central ‘sun’ gear. Typically, a planet 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 supplies the output torque. Nevertheless there are examples of the additional combinations, like the sun gear being set and the band providing output torque.
The main benefit of planetary gearboxes are their high power transmission efficiencies. Typicially this is often around just 3% per stage. Additional to this, the high effiency is delivered despite the compact design giving a sizable torque to size/weight ratio. A few of this is because of the load sharing that occurs over the multiple planet gears.

Typically, a planet carrier is powered by the insight torque which rotates the planets around a fixed outer ring (sometimes known as the annulus). Therefore drives the sun gear which then supplies the output torque. Nevertheless there are examples of the additional combinations, like the sun gear being fixed and the band providing output torque.

Additional to the, the high effiency is definitely delivered despite the compact style giving a huge torque to size/weight ratio. Some of this is because of the load sharing occurring across the multiple planet gears.
