Background

Gear refers to a mechanical element on a rim with gears continuously engaged to transmit motion and power. The use of gears in transmissions has long emerged. At the end of the 19 th century, the successive appearance of the principle of generating the cutting method and the special machine tool and cutter for cutting teeth by using the principle pay attention to the smoothness and rigidity of the gear operation along with the development of production. The steels commonly used for manufacturing gears include quenched and tempered steels, quenched steels, carburized and quenched steels, and nitrided steels. Cast steel is slightly lower in strength than forged steel and is commonly used for gears with larger sizes; the gray cast iron has poor mechanical property and can be used in open gear transmission of light load; the nodular cast iron can partially replace steel to manufacture gears; plastic gears are often used in light loads and where low noise is required, and the mating gears are generally steel gears with good thermal conductivity.
