DETERMINATION OF THE SPECTRAL CHARACTERISTICS OF OPERATIONAL DAMAGE TO GEARBOXES ON THE STAND

Within the framework of this article, issues related to the study of the manifestation of defects and operational damage to gears of gearboxes of transport and technological machines are considered. Examples of graphs of vibration spectra recorded during bench experiments are given. At the same time, the characteristics of the vibrations of gearboxes that occur during their operation as part of the power transmissions of vehicles were studied. During the experiments, the presence of operational damages and defects and their absence were modeled. Their type is analyzed and a classification option is proposed for linking production, technological defects and operational damages to the frequencies of the spectra. In addition, numerical simulation of the presence of the same defects that were investigated during the bench experiments was carried out.
