Gear tooth pitting modelling and detection based on transmission error measurements
Résumé
This paper deals with the experimental validation of the dynamic model of a single stage geared system representative of a back-to-back test rig. The vali-dation relies on loaded transmission error (TE) measurements by using optical en-coders which are compared with simulation results. The influence of tooth pitting on TE is highlighted and it is demonstrated that a simple pit model can reproduce the actual vibrations generated by such surface failures.
