A Comparison Of Methods For The Bearing State Evaluation

Abstract

This paper shows a comparison of several methods commonly used for the bearing state evaluation. A brand new bearing (of the type ZKL1202) as well as a damaged one were used for the tests done at a simple rotating machine. An obvious methods, such as kurtosis, crest factor, a high frequency band RMS value, a spectral analysis of a base band signal and the envelope analysis were used. The results show, that all methods are able to detect the failure bearing with the high reliability compared to the initial state of the bearing.
