A planetary gearbox is a gearbox in which the input and output shafts are aligned. Planetary gearboxes are used to transmit maximum torque in the most compact form known as torque density.
The acceleration hub of a bicycle is a great example of a planetary wheel mechanism: have you ever wondered how to get so much power and capability in such a small hub? For three-speed hubs, a one-stage planetary gear system is used, and for five-speed hubs, 2 stages are used. Each planetary gear system has a deceleration state, a direct coupling, and an acceleration mode.
Mathematically, the smallest reduction ratio is 3:1, and the largest is 10:1. At reduction ratios less than 3, the sun gear becomes too large relative to the planet gears. When the ratio is greater than 10, the sun gear becomes too small, and torque drops. Ratios are usually absolute, i.e., whole numbers.
The inventor of the planetary gearbox is unknown, but Leonardo da Vinci described its function in 1490, and has been in use for centuries.
