small planetary gearbox

A planetary gearbox identifies a gear system in which one or more ‘world’ gears rotate around a central ‘sun’ equipment. Typically, a world carrier is driven by the input torque which rotates the planets around a set outer ring (sometimes known as the annulus). This in turn drives the sun gear which then supplies the output torque. Nevertheless there are types of the additional combinations, such as the sun gear being fixed and the ring providing output torque.

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

Further to the, the high effiency is certainly delivered despite the compact style giving a large torque to size/weight ratio. A few of this is thanks to the load sharing occurring over the multiple planet gears.
