Planetary gearing is a gear system that consists of one or more outer g

Advantages of planetary gears over parallel axis gears include high pow er density, large reduction in a small volume, multiple kinematic combinati ons, pure torsional reactions, and coaxial shafting. Disadvantages include high bearing loads, inaccessibility, and design complexity.The planetary ge arbox arrangement is an engineering design that offers many advantages over traditional gearbox arrangements. One advantage is its unique combination of both compactness and outstanding power transmission efficiencies. A typi cal efficiency loss in a planetary gearbox arrangement is only 3% per stage . This type of efficiency ensures that a high proportion of the energy bein g input is transmitted through the gearbox, rather than being wasted on mec hanical losses inside the gearbox.

ribution. Because the load being transmitted is shared between multiple pla nets, torque capability is greatly increased. The more planets in the syste m, the greater load ability and the higher the torque density. The planetary gearbox arrangement also creates greater stability due to the even distribution of mass and increased rotational stiffness.
