本文通过模拟齿轮的磨削试验,采用正交法研究了展成速度,轴向速度,磨削深度对渗碳淬火的20CrMnMo 和15CrNi_3Mo 钢磨削质量的影响,讨论了磨削变质层内残余应力分布特征,分析了两种材料磨削性能的差异。试验结果表明:磨削深度对磨削质量影响较为显著;变质层内残余拉应力峰值多处在次表面;在相同磨削条件下20CrMnMo 比15CrNi_3Mo 钢具有较厚的变质层,残余拉应力峰值也高。
In this paper, the effects of developing speed, axial velocity and grinding depth on the grinding quality of 20CrMnMo and 15CrNi_3Mo steel hardened by carburizing were studied by using orthogonal test. The residual stress Distribution characteristics, analysis of the difference between the two materials grinding performance. The results show that: the grinding depth has a significant effect on the grinding quality; the residual tensile stress peaks in the metamorphic layer are mostly on the subsurface; 20CrMnMo has a thicker metamorphic layer than the 15CrNi_3Mo steel under the same grinding conditions, and the residual tensile stress peak high.
