Evaluation of a Vibration Diagnostic System for the Detection of Spiral Bevel Gear Pitting Failures.

Abstract

A vibration diagnostic system was used to detect spiral bevel gear surface pitting fatigue in a closed loop spiral bevel gear fatigue test rig. The diagnostic system consists of a personal computer with an analog to digital conversion board, a diagnostic system unit and software. The diagnostic system performs time synchronous averaging of the vibration signal and produces a vibration image of each tooth on any gear in a transmission. Several parameters were analyzed including gear stresswave and raw baseband vibration, kurtosis, peak ratios of several parameters etc. The system provides limits for the various parameters and gives a warning when the limits are exceeded. Three spiral bevel gear tests were monitored with this system. The results show that the system is effective at detecting spiral bevel gear tooth surface pitting damage and other anomalies in the test rig.
