1. The electric vehicle transmission gear and gear shaft are made of 20CrMnTiH material;

2. The tooth making technology adopts Mitsubishi CNC high-precision gear hobbing machine to achieve high precision, high torque, low noise and long life;

3. Automatic controlled carburizing treatment by Sup-Power multi-function furnace to ensure the metallographic structure of the product and the durability of the gear (hardness 58-62HRC);

4. The grinding process adopts Reishauer grinding machine with gear precision of grade 6;

5. Through the gear optimization design and the gear inspection equipment (Klingberg P26), the transmission noise of the gear is effectively controlled (light load 55-60db, heavy load control at 60-65db);

6. The gearbox house adopts high-quality ADC12 aluminum alloy vacuum die-casting process, and processed by DMG Mori Seiki and Mazak five-axis machining center to ensure product accuracy;

7. Product operation stress and deformation is analyzed through ANSYS software finite element analysis to meet high-intensity use and lightweight design;

8. The gearbox assembly uses an online inspection assembly line;
