An Approach to Fault Diagnosis of Rolling Bearings
نویسندگان
چکیده
The present paper aims to demonstrate why usually when theoretical mathematical models are used to compute the frequencies corresponding to a faulty rolling bearing a deviation is obtained between the computed values and the real frequencies emitted by such a device. A laboratory rolling bearing test ring has been developed to perform the current studies. From the obtained results we highlight the impact of the cage rotation frequency on the referred deviation of measured values from the theoretical ones. Key-Words: Fault detection, Fault isolation, Fault diagnosis, Rolling bearing, Condition based maintenance.

متن کاملEarly Fault Diagnosis of Bearings Using an Improved Spectral Kurtosis by Maximum Correlated Kurtosis Deconvolution
The early fault characteristics of rolling element bearings carried by vibration signals are quite weak because the signals are generally masked by heavy background noise. To extract the weak fault characteristics of bearings from the signals, an improved spectral kurtosis (SK) method is proposed based on maximum correlated kurtosis deconvolution (MCKD). The proposed method combines the ability...
