A planetary gearbox identifies a gear system where a number of ‘world’ gears rotate around a central ‘sun’ equipment. Typically, a world carrier is driven by the insight torque which rotates the planets around a fixed outer ring (sometimes referred to as the annulus). This in turn drives sunlight gear which then supplies the output torque. Nevertheless there are types of the 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 can be around just 3% per stage. Additional to the, the high effiency is definitely delivered regardless of the compact style giving a big torque to size/weight ratio. A few of this is thanks to the load sharing occurring across the multiple planet gears.
A planetary gearbox refers to a gear system in which one or more ‘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 known as the annulus). Therefore drives sunlight gear which then provides the output torque. However there are types of the various other combinations, like the sun gear being fixed and the band providing output torque.
