The gearbox gears are the core components of the gearbox, and their performance directly affects the transmission efficiency, reliability, and service life of the gearbox. The following is a detailed introduction to the materials and manufacturing processes of gearbox gears:

Material selection

The gearbox gears need to have high strength, high toughness, and wear resistance. Common materials include:

Forged steel: Low carbon alloy steels such as 20Cr, 20CrMnTi, etc. are improved in tooth surface hardness and core toughness through carburizing and quenching.

Cast steel: suitable for large gears, requiring normalizing treatment to eliminate internal stress.

Ductile iron: Used for light load and low-speed applications, it has good casting performance and anti friction properties.

Plastic: Used in high-speed, light load, and low precision applications to reduce noise.

manufacturing process

Forging blanks: Improving material density and mechanical properties through forging.

Heat treatment: including quenching and tempering, carburizing quenching, high-frequency quenching, etc., to improve the hardness of the tooth surface and the toughness of the core.

Precision machining: Using processes such as gear grinding and honing to ensure gear accuracy.

Gearbox gears are designed and manufactured to meet the special requirements of the gearbox. They are superior to ordinary gears in terms of materials, precision, manufacturing processes, and performance to ensure the stability and reliability of the gearbox.
