Original Abstract

The paper presents an overview of the contemporary applications of acoustic emission method for diagnosis and condition monitoring of anomalous situations that occur during the operation of machines with rotating parts (formation of contact damage, insufficient lubrication, etc.). The main attention is focussed on operational diagnostics of axial and radial bearings. The second part of the text also mentions the possibilities of utilisation of AE method for complementary diagnosis of real state of gears and gearboxes. This summary of selected published experimental works and used evaluation procedures is confronted with the outputs of the experiments carried out in the framework of several projects in the Laboratory of Acoustic Emission of the Institute of Machine and Industrial Design in Brno University of Technology. Based on this review, the significant potential of AE method for more accurate diagnosis of malfunction of machines with rotating parts is done.
