Abstract

In this study, we measured the acoustic emission (AE) and vibration of rolling bearings with an artificial defect on the raceway surface, investigated the detective capacity of AE method for such surface defect , and compared it with that taken from the vibration measurement.
From the measurement results, we concluded that it was possible to detect a raceway surface defect in rolling bearings by measuring AE, and that the detective capacity of the AE method for the surface defect was the same level as that of the vibration measurement within the range of present measurement.
