How Does a Planetary Gearbox Work?

The alignment of the gears can be compared to our solar system where the planets revolve around the sun, hence the name “Planetary Gearbox”.

In the middle of the planetary gearbox, there is a “sun” gear –also known as a central gear. This is often the input gear. Around the outside, there are 2 or more “planet” gears – or outer gears. Surrounding the planet gears there is a ring gear that holds the formation together. The planet gears are connected by a carrier which in turn is connected to the output shaft.
