How an internal-gear hub works?

works of internal gear hub

Did you know? The internal gear hub works on the principle of planetary gearing. Planetary gearing is the system that consists of one or more planet gears or sun gear. In this article, I will tell you about the working of an internal gear hub. 

Three primary speed hubs have one single sun gear. It is attached to the middle of the axle. The sun gear revolves around the identical 3 or 4 planet gears. The gear ring surrounds these planet gears. The gear rings are like teeth from the inside section. 

The internal gear works in a very systematic manner. The planet gears are attached to the planet cage, which revolves around the ring. These models have a different ratio as per the system, which is why not generalizing any ratio here. 

Internal gear hub has three significant parts of gear:

Low Gear

Low gear gives a gear reduction while the sprocket drives the gear ring. Similarly, the planet cage operates the hub, which makes the wheel to turn three or more times of revolution. 

Middle Gear

Inside the middle gear, there is a sprocket which runs the hub directly. In middle gears, the internal gears are always in rotation, along with the motion of sprocket. 

High Gear

In high gear, the planet cage is driven by the sprocket and the hub is driven by the annulus. This on an average ger function increases to 33% and with four revolutions. 

Note: Make sure the compound planet gears are timed while rebuilding a hub and aligned with different sections. Otherwise, the hub will not run roughly and can get damaged. 

This is how an internal gear hub works, and if you have more than three planetary stages, then you need to refer it internally as it has a complex functioning. So this is it, signing off, hope you understood the working of the internal gear hub.
