What exactly is a planetary gearbox?
A planetary gearbox features the alignment of both the input and output shafts. This design excels in transferring maximum torque within a compact form, a concept known as torque density.
Consider the bicycle's acceleration hub as a prime example of a planet-wheel mechanism. Ever wondered how substantial power and multiple capabilities fit into such a compact hub? In a three-speed hub, a one-stage planetary gear system operates, whereas a five-speed hub utilizes a two-stage system. Each planetary gear system includes a reduction state, direct coupling, and an acceleration mode.
Mathematically speaking, the smallest reduction ratio achievable is 3:1, while the largest extends to 10:1. Ratios below 3 cause the sun gear to outsize the planet gears, and ratios above 10 make the sun wheel too small, leading to diminished torque. Typically, these ratios are absolute, represented by integer values.
Although the original inventor of the planetary gearbox remains unknown, its functional description by Leonardo da Vinci in 1490 has paved the way for centuries of practical application.
