Abstract

Gearboxes are critical elements of mechanical systems widely used in aerospace, energy generation, land and naval applications. Early detection of changes in the technical condition of this equipment is of great importance for the optimization of their maintenance costs. Vibration signal components resulting from the presence of the developing faults of meshing gears contain the information that, once extracted from the signal, may allow for a reliable estimation of the meshing gears technical condition. Wavelet bicoherence (WB) based technology has been used to obtain the signal feature characterizing the phase relations between the signal components generated by gear faults in the selected frequency bandwidths. In previous researches, WB has been successfully applied to the detection of artificially created gearbox faults. This paper will present the application of WB in the detection of naturally developing gears faults.
