What is a planetary gearbox?
A planetary gearbox, known for its remarkable torque density, is a compact system where both input and output shafts are perfectly aligned. This innovative design ensures the efficient transfer of immense torque in a space-saving form.
Consider the bicycle's acceleration hub as an exemplary planet-wheel mechanism: Ever pondered how a small hub can deliver such powerful performance? A three-speed hub employs a single-stage planetary gear system, while a five-speed hub utilizes a two-stage system. Each configuration offers a reduction state, direct coupling, and an acceleration mode for varied performance.
Mathematically, planetary gearboxes exhibit reduction ratios ranging from a minimal 3:1 to a substantial 10:1. Ratios under 3 make the sun gear excessively large compared to planet gears, while ratios above 10 render the sun wheel too diminutive, diminishing torque. Typically, these ratios are absolute, represented by integers.
Though the inventor of the planetary gearbox remains unknown, its functional description dates back to Leonardo da Vinci's work in 1490, establishing its enduring legacy over centuries.
