Motor Bevel Gear Set High Precision Meshing For Great Wall Automobile

ⅠProfessional attributes of spiral bevel gears
Spiral bevel gears are the core precision components of automobile transmission systems. Its tooth surface is a spiral arc tooth structure, which is suitable for the two-axis spatial staggered (typical 90° vertical) transmission scene, different from the straight bevel gear, with the progressive contact characteristics of spiral tooth meshing, it solves the pain points of traditional bevel gears with large impact and high noise, and is the key carrier for the power reversal and distribution of automobile differentials and transfer cases.

ⅡThe "joint" role of power transmission
In the transmission architecture of Great Wall Motors, it undertakes the functions of power reversal and torque redistribution:
1.Physical transmission logic: The longitudinal power output by the engine/motor is converted into the transverse power of the driving wheels through the meshing of the helical tooth surface (adapted to the structural requirements of the vehicle's "longitudinal arrangement of power source - transverse drive wheels");
2. Dynamic adjustment value: Under the working conditions of vehicle steering, off-road escape, etc., the high coincidence meshing characteristics of the spiral teeth are used to accurately distribute the torque of the left and right wheels (offsetting the difference in road adhesion and steering resistance) to ensure driving stability and passability, which is the hardware basis of the "intelligent torque management" of the four-wheel drive system.

ⅢIndustrial-grade precision guarantee
From the perspective of professional manufacturing, it reflects the core requirements of automotive precision transmission components:
1. Tooth shape design logic: The helical arc tooth topology optimization design is adopted to balance the triangular relationship of "meshing efficiency, bearing capacity, and noise control" - helix angle matching (15° - 45° range) determines the meshing impact and transmission ratio; Tooth surface modification (drum tooth, tooth drum) compensates for installation error and thermal deformation to ensure the meshing accuracy under all working conditions.
2. Process adaptability: It needs to go through precision processes such as carburizing and quenching + CNC gear grinding to achieve the metallographic structure of "hard tooth surface (wear resistance) + strong and tough tooth core (impact resistance)"; Through five-axis linkage machining, the tooth shape accuracy is guaranteed, the gear accuracy standard of the automotive industry is met, and the adaptability and reliability of the vehicle transmission system are ensured.
