Planetary Gear

Planetary gears refer to a gear system in which, in addition to being able to rotate around their own axis like a fixed axis gear, their axis of rotation also rotates along with the axis of other gears on the planet carrier. The rotation around one's own axis is called "rotation", while the rotation around the axis of other gears is called "revolution", just like the planets in the solar system, hence its name.

This is a planetary wheel used in a robot produced by our company. It is a small and thin gear, with a physical outer circle that is only the size of a spherical door lock commonly used in homes, and a thickness of only 5mm.
