Now, that’s a hard question. Asking who invented gears is like asking who discovered fire or who invented the wheel? There are certain things which have no proper record in history and gears seems to be one of them. Well almost!

We do have some hints from the history on this question. We will share with them with you.
gear invention, gears

Around 50 AD, Greek mathematician and engineer Hero of Alexandria made reference to gears. He followed Archimedes, inventor of Archimedes screw and an odometer that used his screw, driven by a cart’s wheels, to raise and drop balls to record distance. Even more intricate geared devices meant to calculate astronomical movements show up between 150 and 100 BC. source

See we told you before that there are certain things which we are comfortable with now and in fact use it in everyday life and no nothing about its historical significance. Same is the case with gears. We really use them every day and almost every one of us is being benefited by them however we really don’t know who actually invented one. The above-mentioned quote is the only concrete clue that we have on its origins and history. There are many instances in the human history where gears have been popping up from time to time. Since we don’t actually know who invented gears then we thought we will share some history of them with you.

May 17, 1902, The Antikythera Mechanism
gear invention, gears

On May 17, 1902, Greek archeologists found complex precision gear system embedded in an ancient artifact made up of bronze and wood. The device would then be called the Antikythera Mechanism. One of the oldest known scientific equipment which used gears to function.

This 2000-year-old device was most probably used to calculate astronomical positions, predict eclipses and forecast and plan the timings of ancient Olympics. The current scientific community hails this invention as the worlds first the mechanical computer. It contained more than 30 bronze gears which had the build quality and precision of the modern day clock or a Swiss wristwatch.
