Product Description

Special spiral bevel gear for high-speed trains

Product Description

Spiral bevel gear for high-speed trains is used for high-speed train reducer transmission. It is generally made of top-grade alloy steel, such as 20Cr2Ni4A, with a single-stage transmission ratio of 3-5 and a transmission efficiency of 0.94~0.98.

The design, manufacturing, and installation processes are quite complex, requiring very high noise standards. Medium-high speed transmissions are generally adopted, which have been accurately calculated and arranged in terms of material selection, processing technology, heat treatment technology, tooth surface grinding technology, etc. The transmission runs stably, and the gear has a higher carrying capacity, but the manufacturing difficulty is very high. Widely used in high-speed train gearboxes, it has made a great contribution to China's high-speed locomotives.
