摘要
针对球轴承套圈沟道超精研加工工艺对形位精度不敏感和传统套圈沟道磨削工艺在廓形精度和表面粗糙度方面的不足,探索球轴承套圈沟道终加工工艺,提出一种基于圆弧轨迹进给的球轴承套圈沟道ELID成型磨削新工艺方法。从磨削原理上分析该方法的优越性,再进行工件阴极条件下套圈沟道ELID成型磨削试验,测量表面粗糙度达到Ra0.19μm。试验结果表明:在工件阴极条件下,ELID磨削技术在套圈沟道磨削加工中的应用能有效改善表面粗糙度,基于圆弧轨迹进给的球轴承套圈沟道ELID成型磨削方法具有合理性。最后,为了满足新方法的工艺要求,进行圆弧轨迹进给机构设计,为球轴承套圈沟道成型磨削试验平台的搭建提供原理性设计。
It is a reality that the superfinishing process of ball bearing ring raceway is insensitive to geometric precision,and the traditional grinding process of ring raceway is difficult to reach high shape accuracy and low surface roughness. This paper explored the final processing technology for ball bearing ring raceway,and a new processing method of ELID( electrolytic in-process dressing) profile grinding for ball bearing ring raceway based on circular trace feed was proposed. Firstly,the advantage of this method was analyzed in grinding principle.Secondly,the ELID profile grinding experiment of ball bearing ring raceway based on workpiece cathode was carried out. The Ra of processed surface was measured and reached 0.19 μm. The results show that the application of ELID grinding technology in grinding ring groove of ball bearings effectively reduces surface roughness under the condition of workpiece cathode,and the method of ELID profile gringding for ball bearing ring raceway based on circular trace feed is rational. Finally,in order to meet the technological requirements,the feed mechanism of circular trace was designed,which provided the construction of profile grinding experimental platform of ball bearing ring raceway with principle design.
