1) Planetary Gearbox' Feature
In a typical application, the drive power connects to the sun gear. The sun gear then drives the planetary gears assembled with the external gear ring to operate.
The planetary gear train also provides stability due to an even distribution of mass and increased rotational stiffness. Torque applied radially onto the gears of a planetary gear train is transferred radially by the gear, without lateral pressure on the gear teeth.
2) Description of Epicyclic Gear Train
A carrier connects the centers of the two gears and rotates the planet and sun gears mesh so that their pitch circles roll without slip.
A point on the pitch circle of the planet gear traces an epicycloid curve.
