DETERMINATION ON THE STAND OF THE EFFECT OF OPERATIONAL DEFECTS OF GEARS ON THE VIBRATION CHARACTERISTICS OF GEARBOXES

This article is devoted to the study of the influence of disturbing influences accompanying the operation of gearboxes, as one of the key units of power drives, on the spectral characteristics of vibration processes. Graphs of the dependence of the spectrum of the vibration signal of gears, record-ed during bench tests simulating the occurrence of operational defects in them, are presented. The type of spectral characteristics reflecting the normal working condition of gears and the presence of defects in them is analyzed. A variant of the classification of the manifestation of defects and operational damage based on the spectral analysis of vibrations is given.
