Description

Coal Mining Machine Spare Parts Three Planet Gears Planetary Gearset

1) Description of Epicyclic Gear Train

A planetary gearset consists of two gears mounted so that the center of one gear revolves around the center of the other.

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.

In this simplified case, the sun gear is fixed and the planetary gear(s) roll around the sun gear.

2) Feature of Planetary Gearbox

The load in a planetary gear train is shared among multiple planets; therefore, torque capability is greatly increased.

The more planets in the system, the greater the load ability and the higher the torque density.

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.

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 whole set of planetary gear system revolves on its own axis and along the external gear ring where the output shaft connected to the planetary carrier achieves the goal of speed reduction.

A higher reduction ratio can be achieved by doubling the multiple staged gears and planetary gears which can operate within the same ring gear.
