A gear is a mechanical component with teeth that mesh with each other. Widely used in mechanical transmission and the entire mechanical field. Modern gear technology has reached: gear module 0.004~100mm; The gear diameter ranges from 1 millimeter to 150 meters; The transmission power can reach 100000 kilowatts; The rotational speed can reach hundreds of thousands of RPM; The maximum circumferential speed is 300 meters/second.

Straight gears are mainly used to reduce speed and increase torque. In some consumer goods products, they are also used for high-speed transportation. The following are the applications of spur gears in several products: mixers, washing machines, cars, bicycles, mechanical clocks, etc Advantages of spur gears: simple design, easy manufacturing, low cost, high efficiency, and the ability to achieve various transmission ratios Disadvantage of spur gears: high noise

Helical gears are used to transmit heavy loads between parallel shafts at very high speeds. The following are the applications of helical gears in various products: automotive gearboxes, printing and other machinery, conveyors and elevators, factory automation, etc Advantages of helical gears: Compared with spur gears, they have higher load-bearing capacity and contact ratio, smoother, quieter, and better accuracy level Disadvantages of helical gears: Compared to spur gears, they have lower efficiency and increase the axial thrust on the shaft due to the helical angle

Used for high load-bearing capacity requirements, such as differentials and heavy machinery. Advantages of herringbone teeth: reduced axial force, smoother transmission and engagement, reduced noise, self centering ability, high load capacity Disadvantages of herringbone teeth: manufacturing difficulties and high costs

In the future, gears are developing towards heavy-duty, high-speed, high-precision, and high-efficiency directions, striving for small size, light weight, long service life, and economic reliability. The development of gear theory and manufacturing technology will further study the tooth damage mechanism of gears, laying the foundation for establishing reliable strength calculation methods, and improving the bearing capacity of gears and extending their lifespan. In order to improve the smoothness of gear operation and increase the contact area of the gear at full load, the bearing capacity of the gear is improved by studying its elastic deformation, manufacturing and installation errors, and temperature field distribution.

The commonly used steels for manufacturing gears include quenched and tempered steel, quenched steel, carburized quenched steel, and nitrided steel. The strength of cast steel is slightly lower than that of forged steel, and it is commonly used for larger gears; Grey cast iron has poor mechanical properties and can be used in light load open gear transmissions; Ductile iron can partially replace steel in manufacturing gears; Plastic gears are mostly used in places with light loads and low noise requirements, and their paired gears are generally made of steel gears with good thermal conductivity.
