Report discusses application of cepstral analysis to diagnosis of wear in ball-bearing cages in rotating machinery. Ball-cage vibrations and changes in vibrations symptomatic of wear is detected earlier in test than by more conventional methods based on strain-gauge measurements. Particularly useful in diagnoses of gearboxes and rolling-element bearing.
