What is a planetary gearbox?
A planetary gearbox is an engineering marvel where the input and output shafts are perfectly aligned, designed to transfer maximum torque in the most compact form, enhancing torque density.
Consider the bicycle's acceleration hub-it's a stellar example of a planet-wheel mechanism. Ever wondered how such a small hub delivers massive power? In a three-speed hub, a one-stage planetary gear system works its magic, while a five-speed hub employs a sophisticated 2-stage system. Each planetary gear system features a reduction state, a direct coupling, and an acceleration mode.
In mathematical terms, the reduction ratio of a planetary gearbox is fascinating. It ranges from a minimum of 3:1 to a maximum of 10:1. If the ratio dips below 3, the sun gear becomes disproportionally large relative to the planet gears, whereas exceeding 10 makes the sun gear shrink excessively, compromising torque. These ratios are typically absolute, represented by whole numbers.
Though the true inventor of the planetary gearbox remains a mystery, its ingenious design was functionally described by Leonardo da Vinci in 1490, serving diverse applications over centuries.
