Seemingly inconspicuous gears exist in almost any machinery!

As early as 400 BC, gears were invented and continuously applied to waterwheels, wheels and other structures, but its large-scale application did not arrive until 2000.

Ancient gears are made of wood or metal casting, can only transfer the rotary motion between the shaft, can not guarantee the smoothness of the transmission, the bearing capacity of the gear is also very small. The key is that there are too few practical machines to match it, or the creation of gears is a bit advanced, so that people cannot find a practical scene suitable for it.

However, with the development of production, the smoothness of gear operation began to be paid attention. As early as the Middle Ages, people began to apply it to the self-ringing pendulum clock, using the characteristics of the smooth operation of the gear to maintain the punctuality of the clock.

After the 16th century, there were many books that recorded all kinds of gear machinery. At that time, almost all the machinery and equipment in the early industrial revolution needed gears for transmission. Although the invention of gears and machinery is not perfect, the road that mankind has found has far-reaching potential and is worthy of further exploration and depth by later generations.

In 1900, Puford installed a transmission device for the gear hobbing machine, which can process helical gears on the gear hobbing machine. Since then, the gear hobbing machine has been popularized. The development method of processing gears has an overwhelming advantage, and the involute gear has become a widely used gear. In 1955, Sunovikov conducted in-depth research on circular arc gears, and circular arc gears were applied to production.

A variety of more efficient gears and continuously upgraded and optimized machines complement each other to create an unprecedented mechanical age. Subsequently, the application of electricity by humans found a more powerful form of energy conversion, the transmission effect of gears was gradually weakened, and many gear structures were replaced by electrical structures.

If gears are the basis of mechanical equipment in the first industrial revolution, then batteries and wires are the basis of equipment in the electrical age. In the era of information and intelligence, this foundation becomes a chip. However, gears still play their basic functions in places we can't see, especially in many large-scale equipment, many times they are still inseparable from the transmission of gears.

Inside the engine of an aeroplane, gears can still help the propeller run by changing or matching the engine speed to the propeller speed. It is the more precise and silky gears that make the speed and safety of the aero-engine increase simultaneously.

It should be said that gears have been more widely used because of their greater precision. The once common mechanical clocks have been replaced by a large number, but a small amount of luxury goods have been retained. On the whole, the application of gears has not actually decreased, just because more and more human inventions, new electrical and chip structure applications occupy our new inventions, making gears quickly disappear from the public's field of vision, but Still silently dedicated where we can't see.

It should be said that modern gears are acting as a transfer station for mechanical parts and electrical parts. They are the transmission devices of the products of the two eras. Without them, precision instruments may lose their functions.
