摘要

如何根据齿轮齿面精度要求，精准调整装配几何误差，是提升大型数控成形磨齿机床性能的关键技术之一。基于成形磨削系统的误差传递链，砂轮与工件之间的共轭运动关系，利用曲面族包络法建立了包含装配几何误差的成形磨削齿面模型；通过计算理论齿面和包络齿面的差值，进行成形磨削齿面的误差评价，并提出了实现磨削齿面误差评价的流程方法；在此基础上，分析了各项装配几何误差对成形磨削齿面误差的影响。最后，根据分析结果和齿轮齿面精度要求，优化分配了各装配几何误差，并进行了齿轮成形磨削试验。结果表明，该方法为大型数控成形磨齿机床性能的提升提供了可靠的理论依据。

Abstract

The performance of large-scale CNC gear profile grinding machines is needed to be improved. One of key technologies is how to accurately control the assembly geometric errors according to the accuracy requirements of the gear tooth surface. The profile grinding tooth surface model including assembly errors was established using the surface envelope method

based on the error transmission chain of the profile grinding system and the conjugate motion relationship between the grinding wheel and the workpiece. The error evaluation method of the profile grinding tooth surface was proposed by calculating the difference between the theoretical tooth surface and the envelope tooth surface. On the basis of the above

the influence of assembly geometric errors on the profile grinding tooth surface errors was quantitatively analyzed. Finally

the assembly geometric errors were optimized according to the analysis results and accuracy requirements of the gear tooth surface. The gear forming grinding test was carried out. The results show that this method provides a reliable theoretical basis for the performance improvement of large-scale CNC gear profile grinding machines.
