Three Planet Gears Epicyclic Gear Train Of Coal Mining Machine

1) Description of Epicyclic Gear Train

Epicyclic gearing or planetary gearing is a gear system consisting of one or more outer, or planet, gears or pinions, revolving about a central sun gear or sun wheel.

Typically, the planet gears are mounted on a movable arm or carrier, which itself may rotate relative to the sun gear.

Epicyclic gearing systems also incorporate the use of an outer ring gear or annulus, which meshes with the planet gears. P

lanetary gears (or epicyclic gears) are typically classified as simple or compound planetary gears.

2) Advantage of Planetary Gearbox

Planetary gear trains provide high power density in comparison to standard parallel axis gear trains.

They provide a reduction in volume, multiple kinematic combinations, purely torsional reactions, and coaxial shafting.

Disadvantages include high bearing loads, constant lubrication requirements, inaccessibility, and design complexity.
