摘要:In the assembly and using the process of the rolling bearings in high-speed rotating machines, including aero-engines. Because the change of the bearing temperature and pre-stressing force of installation, there will inevitably appear fit clearance between the bearing outer ring and the bearing housing. The fit clearance fault may lead to the impact and friction between bearing and bearing housing, a strong non-linear vibration be caused, the rolling bearing and the entire rotor system vibrate strongly, which leads to the service life of the bearing and rotor system reliability reduces greatly. In this study, the rotor-rolling bearing tester is considered to be the research object, and a rotor-rolling bearing dynamic model with the bearing fit clearance fault is established. The time-domain numerical integration method is used to study the influence of factors such as fit clearance, rotor unbalance, and bearing outer ring tightening torque on the vibration response. Finally, the bearing fit clearance fault test is performed to verify the simulation results. The research work in this study is of great significance for understanding, diagnosing and preventing the bearing fit clearance fault between rolling bearing outer ring and housing. © 2017 Elsevier Ltd
