汽车齿轮珩齿加工缺陷的工艺改进新方法

New Process Improvement Method for Machining Defects of Automobile Gear Honing

通过剖析汽车珩齿加工技术原理,并结合实际案例,介绍了珩齿加工的工艺特点,并提出两种工艺改进方法,一种是在热处理前利用剃齿设备辅助去除高点,另一种是用剃齿设备对珩前毛坯齿面进行粗加工,两种方式均可解决预检不合格、砂轮打刀等问题。将两种方案对比可知,后者在控制质量、成本与效率方面效果更加显著,可使珩齿效率与加工质量得到全面提升。

This paper analyzes the principle of automobile gear honing technology,introduces the characteristics of gear honing technology combined with practical cases,and puts forward two process improvement methods.One is to use gear shaving equipment to assist in removing high points before heat treatment,and the other is to use gear shaving equipment to roughen the tooth surface of blank before honing.Both methods can solve the problems of unqualified pre inspection Problems such as grinding wheel cutting.By comparing the two schemes,it can be seen that the latter has a more significant effect in quality,cost and efficiency,which can comprehensively improve the honing efficiency and machining quality.
