Automotive gears are core components in the transmission system. Unlike other special gears, they adapt to diverse driving conditions such as urban commuting, high-speed cruising and bumpy roads, continuously converting torque and adjusting rotating speed. These gears require strict standards for meshing accuracy and fatigue resistance. Tiny tooth profile errors will cause abnormal noise and vibration, and directly affect the smoothness of gear shifting.
Precision hobbing and honing processes are adopted in production to optimize tooth surface roughness. Proper heat treatment improves core toughness to balance wear resistance and impact resistance. Gears in different positions have separate functions: transmission gears adjust gear ratios, while differential gears balance wheel speed, supporting vehicle start, acceleration and steering.
Long-term load and oil temperature changes will accelerate wear. Regular inspection of tooth surface pitting and abrasion, and timely replacement of worn parts can reduce transmission failures, extend the service life of gearbox assemblies and guarantee driving safety.
