Planetary Gearheads

What is Planetary gearheads?

A planetary gear is a type of gear system comprised of spur gears. In planetary gearing (also known as epicyclic gearing), a center gear, called a sun gear, serves as the input and driver of the set. Three or more “driven” gears (referred to as planets) rotate around the sun gear. Finally, the planets engage with a ring gear from the inside, which makes an internal spur gear design.

Where to use ?

Planetary gear designs are used in a wide range of applications, including automotive and off-road transmissions, wheel drive motors, industrial conveying applications, and others. In fact, even a seemingly simple application like a bicycle uses planetary gearing to power the shifting mechanism. In addition, they can be used as a powertrain between internal combustion engines or connected to electric motors.
