摘要：A nonlinear transverse vibration model of a gear rotor-rolling bearing system was built taking the nonlinear factors, such as bearing clearance, gear backlash and time-varying meshing stiffness into account. By using the method of numerical simulation, the bifurcation laws and the frequency response characteristics of the system were studied primarily. The results reveal that the changes of rotor speed, rolling bearing clearance and bearing damping may lead to chaos through different ways; the increase of rotor eccentricity and the gear backlash will make the system response from simple bearing force excitation frequency and its multiple frequency gradually changes into a complicated one that includes various linear combinations of centrifugal force frequency and the bearing frequency. The gear meshing frequency is one of the system respond factors, but always plays a small role no matter whether the rotor eccentricity or the gear backlash is big or not. © 2017, Central South University Press.
