Automotive gears are the core components of the automotive transmission system, responsible for the important functions of transmitting power, changing speed and torque. Its performance directly affects the efficiency, power, comfort, and reliability of automobiles. The following provides a detailed introduction to the materials and processes of automotive gears.

Material selection

Alloy steel: High strength, high wear resistance, suitable for high load gears.

Permeable carbon steel: has a hard surface and a tough core, suitable for gears that can withstand impact loads.

Powder metallurgy: Low cost, high precision, suitable for small module gears.

manufacturing process

Forging: Improve the mechanical properties of gears.

Cutting processing: including hobbing, hobbing, shaving, etc., to ensure the accuracy of tooth profile.

Heat treatment: carburizing, quenching, tempering, etc., to improve the hardness and wear resistance of gears.

Precision grinding: Improve tooth surface smoothness and reduce noise.

With the development of new energy vehicles and intelligent connected vehicles, automotive gear technology will face new challenges and opportunities. In the future, gear design will pay more attention to lightweight, efficient, and intelligent to meet the needs of energy conservation, emission reduction, and autonomous driving. At the same time, the application of new materials and processes will further enhance the performance and reliability of gears, promoting technological progress in automotive transmission systems.
