本文提出了一种预测非连续成形齿轮磨削过程中热机械诱发的次表面性能变化的方法。该方法面临着工业边界条件，如不同的材料库存去除以及磨削齿面上可能的局部热损伤的缺点。其基本思想是将磨削后的亚表面性能视为“回火时间”和磨削过程中短时间热处理温度的函数。建立了基于局部接触区温度测量的成形齿轮磨削表面层修形的时间-温度图。(C)2018由Elsevier Ltd代表CIRP发布。
In this paper, an approach to predict thermo-mechanically induced changes of sub-surface properties during discontinuous profile gear grinding is presented. The approach faces industrial boundary conditions, such as varying material stock removal as well as the drawback of possible localized thermal damage on the ground tooth flanks. The basic idea is to consider the sub-surface properties after grinding as a function of "tempering time" and temperature due to the short-time heat treatment by the grinding process. Consequently, a time-temperature-diagram showing surface layer modifications for profile gear grinding based on the measurement of local contact zone temperatures has been set up.
