A planetary gearbox refers to a gear system in which a number of ‘planet’ gears rotate around a central ‘sun’ equipment. Typically, a planet carrier is driven by the input torque which rotates the planets around a fixed outer ring (sometimes known as the annulus). This in turn drives sunlight gear which then provides 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 advantage of planetary gearboxes are their high power transmission efficiencies. Typicially this is often around just 3% per stage. Further to this, the high effiency can be delivered regardless of the compact style giving a huge torque to size/weight ratio. Some of this is because of the load sharing that occurs across the multiple planet gears.
A planetary gearbox identifies a gear system where one or more ‘world’ gears rotate around a central ‘sun’ equipment. Typically, a planet carrier is powered by the insight torque which rotates the planets around a set outer ring (sometimes referred to as the annulus). This in turn drives sunlight gear which then provides the output torque. However there are types of the other combinations, like the sun gear being fixed and the band providing output torque.

Additional to the, 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 across the multiple planet gears.
