ADVANTAGES OF PLANETARY GEARBOXES.

EFFICIENCY: Efficiencies of planetary gearboxes can be above 90% while some other types of transmission can be 50% or less. This allows the use of smaller motors.

SIZE: Planetary gearboxes can be half the size of conventional boxes.

WEIGHT: Weight savings can be as high as 60%, allowing smaller, lighter support structures.

MAINTENANCE: Other than routine oil changes, no maintenance is required, eliminating the need to hold spares.

REVERSIBLE: Planetary gears can be equally efficient in either direction. This is an advantage for use in running machinery in both clockwise and anti-clockwise directions.

COAXIAL: The coaxial configuration of input and output shafts allows planetary gears to be installed in line with a motor and a machine.
