ローラーピッチング試験機の計装化

抄録

As a method for evaluating the pitching fatigue characteristic on the gear tooth surface, a roller pitting test is commonly conducted. In this test, a pair of cylindrical test pieces are under the rolling-sliding contact condition with high surface pressure. Conventionally, the test piece was removed from the testing machine during the test and the damage was observed. However, there are possibilities that different parts may come into contact with each other due to installation errors. Therefore, it is difficult to observe accurate damage phenomena. Therefore, in this study, we constructed a system for observing the cylindrical surface on a roller pitching machine and showed its usefulness. We succeeded in observing the surface of pieces at 140 time, magnification.
