| 摘 要： | 研究了高重合度齿轮转子-滚动轴承传动系统的振动强度稳定性以及振动轨道稳定性随系统参数的变化规律。通过振动强度参数稳定域的计算,量化了高重合度齿轮副对齿轮转子 滚动轴承传动系统稳定性提升的贡献大小。结果发现在转子质量偏心较小的条件下,高重合度齿轮系统的振动强度稳定性要比普通重合度齿轮系统提升很多；但在转子质量偏心较大时,高重合度齿轮副的采用对传动系统参数稳定域的扩张并没有显著贡献。通过振动轨道稳定性全局分岔图的计算,明确了滚动轴承游隙、转子质量偏心等参数对高重合度齿轮转子-滚动轴承系统振动轨道稳定性的影响规律,获得了系统各种稳定周期轨道及非周期轨道与对应参数区间的映射关系。

| Abstract: | The vibration intensity stability and movement orbit stability of high contact ratio gear rotor-rolling bearing transimission system was studied.By using the stability domain of vibration intensity parameter,the contribution of high contact ratio gear pair to enhance the stability of the gear rotor-rolling bearing system was quantified.The results revealed that under the condition of small mass eccentricity of the rotor,high contact ratio gear pair was able to improve the system's vibration intensity stability significantly,but high contact ratio gear pair played a limited role to improve the system's vibration intensity stability under the condition of large mass eccentricity of the rotor.The global bifurcation diagram of system's movement orbit stability with the parameters were calculated,the influence rules of clearance of rolling bearing and mass eccentricity of rotor on system's movement orbit stability were obtained.The mapping relation of several key parameters and all kinds of stable periodic orbits and non-periodic orbits were gotten. |
