who invented the planetary gear set

The Invention of the Planetary Gear Set and Its Various Types

The Origin of the Planetary Gear Set

The planetary gear set, a crucial component in many modern machines, was first conceived by the ingenious mind of the ancient Greek philosopher, astronomer and mathematician, Archimedes. This early version of the gear, known as the Antikythera mechanism, was used to predict astronomical positions and eclipses for calendrical and astrological purposes. It was not until the renaissance period that the concept was refined and applied to various mechanical devices.
