| Abstract: | The High Frequency Resonance Technique (HFRT) is in wide use for diagnosing defects in rolling bearings. In some cases, however, the envelope signals and frequency spectra are too difficult to interpret. A model for analyzing the envelope signals and frequency spectra is presented. The effects of load distribution and movement of elements in bearings have been taken into consideration. Experimental results show that early accurated diagnosis of defects in rolling bearings is possible and the results are in fairly good agreement with those by theoretical analysis. |
