What is a planetary gearbox?
A planetary gearbox is a sophisticated mechanical marvel where both the input and output shafts are perfectly aligned. It is expertly designed to transfer the maximum torque while utilizing minimal space, thus achieving exceptional torque density.
Consider the bicycle's acceleration hub-a quintessential example of the planet-wheel mechanism. Have you ever marveled at the immense power and functionality packed into such a compact hub? In a three-speed hub, a single-stage planetary gear system is employed, while a five-speed hub utilizes a two-stage system. Each planet gear system seamlessly transitions through reduction state, direct coupling, and acceleration mode, optimizing your ride.
In mathematical terms, the planetary gearbox offers reduction ratios starting from a refined 3:1 to a robust 10:1. Ratios below 3 result in an oversized sun gear, whereas ratios exceeding 10 lead to a diminutive sun wheel, causing torque reduction. Typically, these ratios are absolute, meaning they are precise integer numbers.
While the inventor of the planetary gearbox remains unknown, its brilliant design was functionally detailed by the genius Leonardo da Vinci in 1490. This ingenious mechanism has been harnessed for centuries, standing the test of time.
