Planetary Gear Ring

The planetary gearset gets its name from its similarity to planets orbiting the sun. Small “planet” gears surround the center “sun” gear, which are finally surrounded by an outer ring. As the ring spins, the planets orbit their sun. This particular example has nine planets and is sized to fit around a finger, for convenient fiddling.
