    Analysis of Surface Initiated Damage in Thrust Bearings with Acoustic Emission

  • Original language description

    Rolling-element bearings are a significant part of every rotating machine and its fault leads to critical malfunction of the whole device. The vibration-based condition monitoring is commonly used to bearings damage detection. However, the bearing fault diagnostic using acoustic emission (AE) technique is more sensitive to incipient defects. This paper presents the results of the experiments on the grease lubricated thrust bearings, where the artificial dents were created on flat raceway to initiate rolling contact fatigue. The AE parameters, vibration level and temperature were used for description of the bearing condition. A comparison of the acoustic emission signal (parametric analysis) obtained on dented and non-dented bearing is presented. It is concluded that the acoustic emission parameters indicate incipient damage early compared to the vibration-based condition monitoring.
