Planetary Gears (Epicyclic Gears) is a gear system consisting of one or more outer gears (planet gears), revolving about a central (sun gear).
行星齿轮箱(行星减速箱)是由一个或多个外围齿轮(行星轮)围绕中央齿轮(太阳轮)旋转的齿轮系统。

An Outer Ring Gear or annulus is incorporated, which meshes with the planet gears.
行星轮安装在的行星架上。
行星架可以相对于太阳轮转动。
行星架的外围是一个齿轮环,该齿轮环通过其内齿和行星轮相咬合。

One of the two remaining components is an input, providing power;
The last component is an output, receiving power.
太阳轮、行星架和齿轮环,这三个部件,
其中之一被固定,第二个作为输入,第三个作为输出,可以获得不同的减速比。
The Ring Gear is held stationary.
The Sun Gear is used as input.
The Planetary Carrier is the output.
The lowest gear ratio !
齿轮环固定,太阳轮作为输入,行星架作为输出。此时,获得最大的减速比。
The Planetary Carrier is held stationary.
The Sun Gear is used as input.
The Ring Gear is the output.
Planetary Gears simply rotate about their own axes – spin.
行星架固定,太阳轮作为输入,齿轮环作为输出。此时,行星轮仅自转。
Slow, but Powerful.
Fast, but Powerless.
速度变快,扭矩变小;
速度变慢,扭矩变大。
A higher reduction ratio can be achieved by using multiple staged gears and planetary gears.
多级行星齿轮箱可以获得更大的加速比。
