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. © 2017, Editorial Department of Journal of Aerospace Power.
