Possibilities of the damage diagnostics of gearboxes and bearings with acoustic emissions method

Popis výsledku v původním jazyce

Experiments focused on identification of damage of bearings and automobile gearbox with usage of acoustic emission method is presented in this paper. The first group of experiments was carried out on durability test stations for radial and axial bearings. Sensing of AE signal on devices for radial bearings testing was complicated by the position of the tested bearing inside the station. As a solution, waveguides were used, with one end touching the outer ring of the bearing. Other sensors were placed onthe surface of the testing station. The second group of tests consisted of measuring of signal of an intact and a damaged automotive gearbox during different functional conditions. In the gearbox the needle bearing, axial bearing and tooth wheel in fifth speed gear were artificially damaged. The goal of these experiments was to create the methodology of measurement and to compare the records of measurement of acoustic emission signal with level of vibration, noise emission and temperatu
