- Abstract:
- Planetary gearboxes are more widely used in many mechanical devices because of many of the advantages. The vibration responses are more complex than that of fixed -axis gearboxes，therefore the corresponding dynamic models established and fault diagnosis have become the research difficulty and hotspot in recent years. At present，most of the dynamic models and analysis of planetary gearboxes are under the normal condition，while few focused on the studies of faulty ones. The fault characteristics analysis of the planetary gear sets is lacked of research on vibration mechanism. Aiming at these shortcomings of present research，a dynamic model of planetary gear system was established，considering the time-varying effects of transmission paths. The expression of the meshing stiffness under the sun gear broken condition was calculated. Using the model，the spectral response characteristics were obtained. Then compared with test signal，the accuracy of the dynamic model analysis is verified.
