Damaged rolling contact bearings generate vibration. These vibrations may be measured and separated from other vibrations in a machine to analyze and interpret the condition of the bearings and other associated problems. The envelope technique is used to measure the magnitude or energy distribution of the shock emitted whenever a defect in a bearing comes into contact with another surface. Frequency analysis of the enveloped signal determines the type of fault and the amplitude level, the extent of the fault. In this paper, the envelope technique is used to analyze alignment problems associated with cooling tower fans in a large refinery processing crude oil. Experimental data obtained are reported.
