Rail Transit High-Speed Train Gearbox Gear With Advanced Technology

1. The gearbox of rail transit high-speed train is a key component in the transmission system of high-speed train. Its main function is to transmit the power generated by the motor to the wheels to drive the train.
2. The precision level of gears in rail transit high-speed train gearboxes is usually very high, with low noise and long-term reliability.

Accuracy requirements of high-speed train gearbox gear:

1. Tooth profile accuracy: The gear profile error needs to be controlled within a very strict range to ensure smooth gear meshing and reduce noise and vibration.
2. Tooth pitch accuracy: The gear pitch error also needs to be strictly controlled to ensure correct gear meshing and transmission efficiency.
3. Tooth direction accuracy: The control of tooth direction error is crucial for high-speed train gearboxes because it affects the smooth operation and life of the gears.
