High-speed motor bevel gear product details:
Spiral bevel gears for high-speed EMUs, used for high-speed rail EMU reducer transmission. The material is generally alloy steel, 20Cr2Ni4A and other alloy steel, 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 gear of high-speed motor car is quite complex, and the noise requirements are very high, generally medium and high-speed transmission, and the material selection, processing technology, heat treatment process, tooth surface grinding process, etc. are calculated and arranged; The transmission power is designed to meet the requirements of the whole machine. The transmission runs smoothly and the gear carrying capacity is high, but the manufacturing difficulty is very high, and it is widely used in the gearbox of high-speed rail bullet trains, making great contributions to China's high-speed locomotives.
