product manual

Special spiral bevel gears for high-speed trains are used for the transmission of high-speed trains reducer.The material is generally high-grade alloy steel such as top alloy steel 20Cr2Ni4A, the single-stage transmission ratio is generally 3-5, and the transmission efficiency is generally 0.94-0.98.The design, manufacturing and installation process of spiral bevel gears for high-speed trains are quite complicated, and the noise requirements are very high. Generally, they are medium and high-speed transmissions. The material selection, processing technology, heat treatment process, tooth surface grinding process, etc. are all accurately calculated and arranged; transmission transmission power It is designed to meet the safety requirements of the whole machine.The transmission runs smoothly and the gear carrying capacity is high, but it is very difficult to manufacture. It is widely used in high-speed train gearboxes and has made great contributions to my country's high-speed locomotives.

Product advantages:

Professional production of high-quality materials, imported high-precision equipment can be customized design and processing.

Rugged and durable, high strength, large torque, and good comprehensive mechanical properties.

High transmission efficiency, smooth transmission, long service life, noise reduction and vibration reduction.


 Focusing on 35 years of industry experience in the gear processing industry, product warranty for 1 year.


The tooth surface is carburized and quenched, with strong wear resistance, reliable work and high load-bearing capacity.


The tooth surface can be ground, and the precision after grinding is comparable to high-end imported products
