在这项研究中，一个动力学模型的直齿圆柱齿轮副的动态响应的影响，齿轮齿分度误差进行调查。该横扭耦合动力学模型考虑了齿轮啮合刚度随时间的变化以及共振区齿间距引起的非线性。该模型以准静态传动误差时间轨迹作为主要激励，预测了频域动态啮合力和动态传动误差谱。这些长周期准静态传输误差的时间轨迹测量使用单位比直齿轮副具有一定的故意索引错误。采用具有用于测量准静态传动误差的专用仪器的特殊测试装置来对仅在测试齿轮的一个或两个齿处具有确定性间距误差和随机间距误差的齿轮执行多个实验，其中所有测试齿轮齿具有与典型生产齿轮中一样的随机误差分布。(C)2015爱思唯尔有限公司版权所有。
In this study, a dynamic model of a spur gear pair is employed to investigate the influence of gear tooth indexing errors on the dynamic response. This transverse-torsional dynamic model includes periodically-time varying gear mesh stiffness and nonlinearities caused by tooth separations in resonance regions. With quasi-static transmission error time traces as the primary excitation, the model predicts frequency-domain dynamic mesh force and dynamic transmission error spectra. These long-period quasi-static transmission error time traces are measured using unity-ratio spur gear pairs having certain intentional indexing errors. A special test setup with dedicated instrumentation for the measurement of quasi-static transmission error is employed to perform a number of experiments with gears having deterministic spacing errors at one or two teeth of the test gear only and random spacing errors where all of the test gear teeth have a random distribution of errors as in a typical production gear.
