What exactly is a planetary gearbox?
A planetary gearbox, a marvel of mechanical engineering, features its input and output shafts aligned. Renowned for its ability to transmit the maximum amount of torque in a remarkably compact form, it is celebrated for its exceptional torque density.
Consider the bicycle's acceleration hub as a vivid example of a planet-wheel mechanism. Have you ever marveled at how such immense power and capability are harnessed within such a small hub? For a three-speed hub, a single-stage planetary gear system is employed, while a five-speed hub utilizes a two-stage system. Each planetary gear mechanism includes a reduction state, a direct coupling, and an acceleration mode, showcasing its versatile functionality.
From a mathematical perspective, the smallest reduction ratio achievable is 3:1, while the largest hovers around 10:1. Ratios below 3 cause the sun gear to become disproportionately large compared to the planet gears, whereas ratios above 10 render the sun wheel too small, diminishing torque. Typically, these ratios are absolute, or integer-based, ensuring precise calculations.
Though the identity of the planetary gearbox's inventor remains a mystery, its functionality was first described by the brilliant Leonardo da Vinci in 1490. This ingenious invention has been harnessed for centuries, a testament to its enduring utility.
