| Summary: | A model of a two rotors-ball bearing-gear coupling systems which considering ball defects on bearing was established. In this model the meshing force of gear coupling and ball defects on bearing was considered. A test facility was constructed to verify the simulation results. After simulation and experiment, it was found that there are sideband frequencies beside VC frequency and its multiple frequencies can be found in the faulted rotor system in the spectrum. From the acceleration signal of experiment, it was found the signal of the bearing fault performs as impacts in the high frequency range without any patterns. The characteristics of ball defects of bearing on a two rotors-ball bearing-gear coupling systems were analyzed. It can help analyze the stability of the system and the fault characteristic of ball bearing. |
