What is a planetary gearbox?
A planetary gearbox is ingeniously designed to perfectly align both the input shaft and the output shaft. This type of gearbox is renowned for its ability to transmit the highest levels of torque within a compact framework, often referred to as offering outstanding torque density.
The bicycle's acceleration hub stands as a marvelous illustration of a planet-wheel mechanism. Ever pondered how such a modest hub can deliver extraordinary power and capabilities? For a three-speed hub, a one-stage planetary gear system is brilliantly employed, while a five-speed hub utilizes a sophisticated 2-stage system. Each planetary gear system is versatile, offering a reduction state, direct coupling, and an acceleration mode.
From a mathematical perspective, the smallest reduction ratio achievable is 3:1, while the largest is 10:1. If the ratio drops below 3, the sun gear becomes disproportionately large compared to the planet gears. Conversely, a ratio exceeding 10 causes the sun wheel to shrink excessively, reducing torque. Typically, these ratios are absolute, represented by integer values.
The origins of the planetary gearbox remain shrouded in mystery, but it was functionally depicted by the genius Leonardo da Vinci circa 1490, and has served a pivotal role in mechanical applications for centuries.
