Material selection for automotive gears

Source: Zhejiang Jinchi Machinery Co.,Ltd.Release time: 2025-04-27

Automotive gears are the core components of automotive transmission and power distribution systems, and their performance directly affects the driving efficiency, comfort, and safety of vehicles. The following are material choices for automotive gears:

tempered steel

By quenching and tempering treatment, toughness and strength are improved, suitable for gears that can withstand moderate loads.

Hardened Steel

Obtained high hardness and wear resistance through quenching treatment, suitable for high load gears.

Carburized quenched steel

After surface carburizing and quenching, the gear surface becomes hard and the core becomes tough, capable of withstanding large impact loads. It is commonly used in automotive transmission gears.

nitriding steel

By nitriding treatment, a high hardness nitride layer is formed on the surface to improve wear resistance and fatigue resistance, suitable for high-precision gears.

The design and manufacturing of automotive gears have a significant impact on the performance, reliability, and efficiency of vehicles. With the development of the automotive industry, gear technology is constantly innovating to meet higher performance requirements.
