Angular-misaligned shafts connected by gear coupling is the main study object. First introduced a model that consists of two angular-misaligned rigid shafts mounted on bearings. The non-dimensional lateral vibration differential equation of angular-misaligned shaft during startup process is derived, the equation is investigated by numerical integral method. The result reveals that the vibration peaks...
Induction motor-gearbox group vibrations, caused by bearing defects, result in the modulation of the stator current. In this research, bearing defect is detected using the stator current analysis and mechanical vibration. The advantage of this method is in the detection of incipient faults. Faulty balls in bearing suspension and eccentricity are the relatively common faults in induction motors coupled...
