What is a planetary gearbox?
A planetary gearbox is an innovative mechanical system where the input and output shafts are in perfect alignment. This gearbox is ingeniously designed to transmit maximum torque with unparalleled compactness, a feature that's fondly known as torque density.
Think about the bicycle's acceleration hub as a brilliant example of a planet-wheel mechanism. Ever marvel at the immense power and functionality packed into such a compact hub? For a three-speed hub, a one-stage planetary gear system is employed, while a five-speed hub uses a sophisticated 2-stage system. Each planetary gear setup ingeniously provides a reduction state, direct coupling, and an acceleration mode.
In mathematical terms, the smallest reduction ratio achievable is 3:1, and the largest is 10:1. Ratios below 3 cause the sun gear to become disproportionately large compared to the planet gears, while ratios above 10 lead to a sun wheel that's too small, diminishing torque. These ratios are typically absolute, ensuring integer precision.
The brilliant invention of the planetary gearbox, though its origin remains a mystery, was functionally illustrated by the genius Leonardo da Vinci in 1490. This invention has proven its worth over centuries.
