电子束焊接在齿轮焊接中的应用

Application of Electron Beam Welding in Gear Welding

研究分析了电子束焊接的基本原理及焊接质量的主要影响因素。并结合项目开发实例,以某商用车六档手动变速器的从动六档齿为研究对象,介绍了优化焊接工艺参数及结构设计,解决焊接裂纹问题。试验发现:在焊接结构不变情况下,焊接深度较深时通过改变工艺参数难以消除焊接裂纹;同时优化焊接结构并搭配合适的焊接工艺可消除焊接裂纹,并可同时满足焊接深度等技术要求。

This article studied and analyzed the basic principle of electron beam welding and the main factors affecting welding quality.In combination with the developing project case,this paper,taking the sixth driven gear of a 6-speed manual transmission of a commercial vehicle as the research object,introduced the optimization of welding process parameters and structural design to solve the welding crack problem.The experiment finds that when the welding structure remains unchanged,it is difficult to eliminate welding cracks by changing the process parameters when the welding depth is deeper;Simultaneously optimizing the welding structure and matching it with appropriate welding processes can eliminate welding cracks and meet technical requirements such as welding depth.
