The Planetary Gear Set: What is it and how does it Work?

From small gears to big planetary gears, all are entirely responsible for transmitting force in any mechanism. It will be nearly impossible to provide drive without their presence. Now featuring the planetary gear, they provide automotive transmission to every automobile. Focusing on the structure, it contains fix axis gear trains responsible for the speed reduction, acceleration, and torque in a smaller package.

As a fact, the planetary Gear Set is much better than the standard gears and pinion reducers. The speed of the planetary gear depends upon its mode of application. This system consists of four main parts including the sun gear, planet gear, ring gear and carrier

Working of Planetary Gear

As soon as the ring gear is stationary, the sun gear comes in the rotational motion. At point A, the planet gear should have spin speed and point B the speed will be zero as the ring gear is stationary.

Actually, all these conditions are possible at one time because the planet gear will spin as well as turn. This spinning will produce the velocity as the interaction between the top and bottom points. On the other side, the turning produces a unit direction of velocity in the planetary Gear Set.
