What is a planetary gearbox?
A planetary gearbox is ingeniously designed to have both the input shaft and the output shaft in perfect alignment, facilitating an unparalleled transfer of maximum torque within a remarkably compact form. This is often referred to as torque density, making it an indispensable component in various applications.
The acceleration hub of a bicycle exemplifies the planet-wheel mechanism beautifully. Ever wonder how such potent power and capabilities are packed into a compact hub? For a three-speed hub, a single-stage planetary gear system is employed, whereas a five-speed hub utilizes a two-stage system. Each planetary gear arrangement boasts a reduction state, direct coupling, and an acceleration mode, collectively optimizing performance.
Explained in mathematical terms, the smallest feasible reduction ratio for a planetary gearbox is 3:1, while the largest extends to 10:1. If the ratio falls below 3, the sun gear becomes disproportionately large compared to the planet gears. Conversely, at ratios exceeding 10, the sun wheel diminishes too much, leading to a consequential drop in torque. These ratios are typically absolute, expressed as whole numbers.
While the mastermind behind the invention of the planetary gearbox remains a mystery, it was artistically conceptualized by Leonardo da Vinci in 1490. This revolutionary design has stood the test of time, serving crucial roles for centuries.
