What is a planetary gearbox?
A planetary gearbox is a sophisticated transmission system with both its input and output shafts perfectly aligned. Renowned for its ability to transmit the highest torque possible within the most compact form, it excels in torque density, making it a marvel of engineering efficiency.
Consider the bicycle's acceleration hub, a prime example of a planet-wheel mechanism: Ever wondered how such immense power and capability are packed into a seemingly tiny hub? A three-speed hub incorporates a one-stage planetary gear system, while a five-speed hub utilizes a two-stage system. Each planetary gear system boasts a reduction state, direct coupling, and acceleration mode.
In mathematical terms, planetary gearboxes offer a reduction ratio range from a minimum of 3:1 to a maximum of 10:1. Below a 3:1 ratio, the sun gear becomes disproportionately large compared to the planet gears, while above a 10:1 ratio, the sun wheel becomes overly small, leading to a torque drop. These ratios are typically absolute, represented as integer values.
Though the original inventor of the planetary gearbox remains a mystery, it was functionally described by the genius Leonardo da Vinci in 1490, and has been harnessing power with precision for centuries.
