摘　　要：为提升齿轮传动误差的测量技术,提出一种基于应力应变法的直齿圆柱齿轮传动误差测试方法,并通过有限元法和理论计算与测试结果进行相互验证,证明应力应变法的可行性,对理论计算结果与试验测试结果进行分析,结果显示两者所得到的齿轮传动误差变化趋势一致,进一步证明应力应变法的有效性。并且对齿轮啮合过程中齿轮箱体变形情况进行仿真与测试,测试结果表明:齿轮箱体变形对齿轮传动误差影响很小,可忽略不计。通过对应力应变法测量齿轮传动误差的研究,可为测量齿轮传动误差提供一种新的快捷、简便、实用的测量方法。In order to improve the measurement technology of gear transmission error,a method for measuring the transmission error of spur gear based on the stress strain method is proposed,and the feasibility of the stress strain method is proved through the mutual verification of the finite element method and the theoretical calculation and test results.The theoretical calculation results and the test results are analyzed,and the results show that the variation trend of the gear transmission error obtained by the two methods is consistent,The validity of the stress-strain method is further proved.The deformation of gear box during gear meshing is simulated and tested.The test results show that the influence of gear box deformation on gear transmission error is negligible.The study of measuring gear transmission error through the stress strain method provides a new,fast,simple,and practical measurement method for measuring gear transmission error.
