The processing characteristics of transmission gears

(1) High precision requirements:

Tooth profile accuracy: Typically required to achieve ISO 6-8 grade precision, with surface roughness Ra ≤ 1.6μm, ensuring smooth meshing and low noise.

Dimensional stability: After heat treatment, deformation (e.g., tooth alignment error ≤0.02mm) should be controlled to avoid affecting assembly and transmission efficiency.

(2) Complex processing procedures

Multi-process collaborative processing, including forging → rough machining → heat treatment → precision machining → surface treatment, requires seamless integration at each stage.

Special Process Applications: For instance, the combination of hobbing + shaving/hobbing + grinding, or the use of honing to further enhance surface quality.

(3) Compatibility of Materials and Heat Treatment:

Select heat treatment processes (such as carburizing and induction hardening) based on gear load requirements, balancing hardness and toughness to avoid core softening or surface embrittlement.

(4) Surface Hardening Technology:

Carburizing/Nitrocarburizing: Surface hardness reaches 58-62 HRC, with a case depth of 0.8-1.2mm (heavier gears may have a deeper case).

Shot peening: Introduces residual compressive stress, increasing fatigue life by 20%-30%.
