摘要:

为了探寻滚齿机滚削振动特性,根据机床滚刀主轴结构、工艺参数及Euler-Bernoulli梁振动理论,建立了滚刀主轴X向的振动响应函数模型,开展了振动试验测试,得到了滚齿机滚刀主轴振动频率、X向振动加速度及位移数据曲线。经分别比较滚刀主轴振动加速度与位移最大幅值的理论与测试数据,两者相对误差均小于5%,表明理论与试验值的一致性较好,验证了该型号滚齿机滚刀主轴振动响应函数模型推导的正确性;并且由测试数据分析可知,该研究对滚齿机主轴结构、加工工艺参数选择与优化及加工误差预测具有指导意义,为该系列其他滚齿机主轴振动特性理论与试验研究提供经验借鉴与参考价值,且也为滚齿机振动特性的后期深入与实用性研究奠定理论与试验基础工作。

Abstract: In order to explore the hob cutting vibration characteristics of computer numerical control (CNC) gear hobbing machine, According to the machine tool structure, process parameters and Euler-Bernoulli beam vibration theory was established the hob spindle X direction of vibration response function model, the vibration test is carried out, the vibration frequency and X direction vibration acceleration and displacement curve of the hob spindle are obtained. Compared the theoretical results of calculation with the practical experimental values of the maximum amplitude of the vibration acceleration and displacement of the hob spindles, the relative error of the results are all lower than 5%. It shows that the theory and the experimental results are in good agreement, which proves the correctness of the theory model of the vibration response function model of the hob spindle of this type of gear hobbing machines. And From the test data analysis, it is known that this research has guiding significance to the spindle structure and processing parameter selection and the optimization, and the prediction of the machining error about gear hobbing machines, It can provide experience reference and reference value for the other series gear hobbing machines of the hob spindle of the vibration characteristic theory and experiment research, and also lay a theoretical and experimental foundation work for the further research on vibration characteristics of gear hobbling machine in future.
