摘　　要：通过激光焊接工艺将差速器半轴齿轮和堵盖紧密结合在一起,保证半轴齿轮和堵盖组能储油并防止润滑油泄漏,是差速器半轴齿轮生产制造中的重要手段。本文探讨了通过优化母材过盈量、采用焊接母材切碳处理、预防焊接开裂等关键技术,实现了差速器半轴齿轮和堵盖组件激光焊接质量的显著提升。The dif ferential pinion gear and plug are tightly combined together by laser welding process,ensuring that the pinion gear and plug assembly can oil and prevent lubricating oil from leaking,which is an important means in the production and manufacturing of diff erential pinion gears.This paper discusses the optimization of the material interference,the use of welding parent material decarburization treatment,and the prevention of welding cracks and other key technologies to significantly improve the quality of laser of diff erential pinion gears and plug assemblies.
