Monitoring of Acoustic Emission Signal of Loaded Axial Bearings
Original language description
The disclosure of initial stadium of contact fatigue of rotating machines is very difficult. At present, some methods which are suitable for diagnosis exist, such as vibration method, shock pulse method, acoustic emission and others. The article describes laboratory tests with axial bearings which are monitored by acoustic emission method. In the article, experimental stands, measuring devices and chosen types of axial bearings are presented. The exploitation of acoustic emission signal for the lifetimeevaluation of selected bearings is shown with the characteristics as number of counts, rise time, maximal amplitude or duration of event. The bearing lifetime is separated to three stages and a representative sample in its time and frequency domain foreach of them is chosen. Final failures of the bearings are shown too. The paper is focused also on examples of results obtained with continuous AE signal sensing
