由齿轮机构的总体传动误差概念引申出含有齿距啮合偏差的单齿传动误差,并根据齿面的几何关系,给出齿距啮合偏差对单齿传动误差曲线影响的偏移式;然后,在Y9550型滚动检验机的基础上搭建传动误差检测平台并进行测量试验,得到准双曲面齿轮副两种传动误差的测量结果;最后,利用JD45+型齿轮测量机所测的齿距偏差数据对理论传动误差曲线进行修正,进而分析了轮齿的啮合状态.通过对理论与实际传动误差曲线的对比,验证了齿距啮合偏差对传动误差的影响方式.试验结果表明:在轻载条件下,实际单齿传动误差可近似由理论设计曲线和齿距啮合偏差组成的综合仿真曲线来替代,从而为进一步研究实际工况下齿轮传动的运动精度和工作平稳性奠定了基础.
Based on the general transmission error of gear mechanism, the single-tooth transmission error with gear pitch mismatch is derived. Based on the geometric relationship of tooth flank, the deviation of gear pitch error on single-tooth transmission error curve is given. Then, Y9550-based rolling test machine based on the construction of transmission error detection platform and measurement tests to get the hypoid gear pair two kinds of transmission error measurement results; Finally, the use of JD45 + gear measuring gear pitch deviation data on the theoretical transmission The error curve is corrected and the meshing state of the gear teeth is analyzed.Through the comparison of the theoretical and actual transmission error curves, the influence of gear meshing deviation on the transmission error is verified.The experimental results show that under the condition of light load, The gear transmission error can be approximated by a comprehensive simulation curve composed of the theoretical design curve and the gear pitch deviation, which lays the foundation for further research on the movement accuracy and work stability of the gear transmission under actual conditions.
