利用自行设计的齿轮试验台，通过测量几种齿轮副的动态传动误差，实验研究了渐开线重合度对直齿圆柱齿轮副扭转振动特性的影响。实测强迫响应曲线，和谐波振幅的动态传动误差进行比较，上面和下面的齿轮啮合共振的未修改和修改的齿轮具有各种渐开线重合度值。定量分析了渐开线重合度对动态传动误差的影响，提出了一套通用的、经过实验验证的设计准则，以合理选择渐开线重合度，实现齿轮系统的静特性。
The influence of involute contact ratio on the torsional vibration behavior of a spur gear pair is investigated experimentally by measuring the dynamic transmission error of several gear pairs using a specially designed gear test rig. Measured forced response curves are presented, and harmonic amplitudes of dynamic transmission error are compared above and below gear mesh resonances for both unmodified and modified gears having various involute contact ratio values. The influence of involute contact ratio on dynamic transmission error is quantified and a set of generalized, experimentally validated design guidelines for the proper selection of involute contact ratio to achieve quite gear systems is presented, A simplified analytical model is also proposed which accurately describes the effects of involute contact ratio on dynamic transmission error.
