Planetary Gearbox

Understanding Planetary Gearboxes

A planetary gearbox, or epicyclic gearbox, features a unique arrangement of a central 'sun' gear, multiple 'planet' gears revolving around the sun, a 'planet carrier' holding the planets, and an outer 'ring' gear with internal teeth. This configuration offers several significant advantages.

Key Advantages:

• High Torque Density: The load is shared among multiple planet gears, allowing the gearbox to handle higher torque in a smaller size compared to other gearbox types.
• Compactness: The inline, coaxial arrangement of input and output shafts results in a very compact gear reducer package.
• High Reduction Ratios: Significant speed reduction can be achieved in a single stage, with multi-stage designs allowing for extremely high overall ratios.
• High Efficiency: Planetary gear trains offer high transmission efficiency due to rolling contact and even load distribution.
