Tooth defect detection in planetary gears by the current signature analysis: numerical modelling and experimental measurements

Monitoring transmission systems is a huge scientific focus to prevent any anomaly and malfunctioning damaging the system. Several methods were used investigate gears behaviour mainly its state. And until last century, vibrations signals most performing technique in this field. However, nowadays, other alternatives are considered more accurate accessible such as controlling motor current study of mechanical Within context, paper aims electromechanical interaction between double stage planetary gearboxes driven by an asynchronous machine. The model based on Park transformation for modelling machine torsional describe dynamic double-stage gearbox. Through approach, numerical simulations illustrate impact tooth gear defect signature current. results obtained from will be presented time domain frequency using fast Fourier transform Hanning window highlight frequencies phase spectrum. This work distinguished validating experimental measurements, which displayed order justify sensitivity developed.
