【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 stability of vibration intensity and the variation of vibration track stability with system parameters of high coincidence gear rotor-rolling bearing transmission system are studied. By calculating the stability region of vibration intensity parameters, the contribution of high coincidence gear pair to the stability improvement of gear rotor-rolling bearing transmission system is quantified. The results show that the vibration strength stability of the high coincidence gear system is much higher than that of the common gear system under the condition of low mass eccentricity of the rotor, but when the rotor mass eccentricity is greater, the vibration strength stability of the gear system is much higher than that of the common gear system. The adoption of high coincidence gear pair has no significant contribution to the expansion of the stability region of transmission system parameters. By calculating the global bifurcation diagram of vibration track stability, the influence of parameters such as roller bearing clearance and rotor mass eccentricity on the vibration track stability of high coincidence gear rotor-rolling bearing system is clarified. The mapping relations between stable periodic orbits and aperiodic orbits and corresponding parameter intervals are obtained.
