This paper reports on surface fatigue testing. The goal was todevelop models for predicting wear. As part of this goal, the studyreports on developing an understanding of the stresses and wearpredictors using FZG tests. Since the focus was on micropitting,the first tests used the method described in FVA Information SheetNo. 54/I-IV. Later, the procedure was modified to account forhigher contact stress levels that are predicted for the heavilycrowned and tip relieved AGMA test gears that were manufactured asa part of the AGMA tribology test program. This paper providesextensive analysis that includes detailed topography measurementsof the tooth profiles, predictions of contact stresses and contactpatterns. It discusses factors that affect contact stresses, flashtemperatures, and test film thickness.
