What is a planetary gearbox?
A planetary gearbox is a marvel of engineering where both the input and output shafts are perfectly aligned. This design, revered for its compact form, efficiently transfers the maximum torque with remarkable torque density.
Imagine the incredible power and capabilities packed into the bicycle's acceleration hub-it's the magic of the planet-wheel mechanism! In a three-speed hub, a one-stage planetary gear system works wonders. Meanwhile, a five-speed hub employs a sophisticated 2-stage system. Every planetary gear system boasts a reduction state, a direct coupling, and an acceleration mode, demonstrating unparalleled versatility.
In the realm of mathematics, the smallest reduction ratio achievable is 3:1, while the largest extends to 10:1. With ratios below 3, the sun gear becomes disproportionately large compared to the planet gears. Conversely, ratios exceeding 10 lead to a minuscule sun wheel and a consequential drop in torque. Typically, these ratios are absolute, represented by integer values.
The genius behind the invention of the planetary gearbox remains a mystery. However, its functional essence was brilliantly outlined by Leonardo da Vinci in 1490, and it has been ingeniously utilized across centuries.
