- In the article are presented chosen research results of influence of local defects in toothed gear on the vibroacoustic signal. Vibroacoustic methods of diagnostics are perfectly suitable to the task of monitoring the status of devices during their normal work. Monitoring of vibrations during operation is particular importance for industrial toothed gear as well gears working in the power transmission systems of aircrafts. Taken into account negative consequences of damages in toothed gears, determination of changes in vibroacoustic signal can prevent possible failures, and is therefore very important. Researches were performed with use residual signals created from synchronously averaged time signals generated by identified dynamic model of toothed gear working in circulating power system. Superior purpose of work is development of effectively methods of damage detection, especially in its early stages, what has great importance during operating aircrafts. The study shows that local damage of the wheels affects changes in the frequency distribution of vibroacoustic signals energy. The degree of damage significantly impacts to the possibility of detecting it on the basis of time signals analyses.
