Abstract

PURPOSE: To accomplish discrimination of flaw caused on the rolling bearing by determining the difference in the waveform of frequency axis signal for the rolling bearing of the rotating shaft between the time of the normal operation and the inspection.
CONSTITUTION: First, oscillatory waveform data obtained from the normal bearing is digitalized and then, stored in a memory 5b. The waveform data of memories 5a and 5b is fed to an operation sector 6 where an operation is performed to obtain the results of the inspection. Conversion is made from the time region to the frequency region and the result is converted to a power spectrum. Then, the normal wave form is subtracted from the inspection waveform to determin the difference between the power spectrums of the two waveforms. The results is indicated by a display section 7.
