Bending Fatigue Strength of Spur Gears in Low-Cycle Range

TLDR: In this article, the bending fatigue strength of spur gears in low-cycle range was investigated and the validity of these calculating methods was confirmed by carrying out a static loading test. And the characteristics of bending fatigue in spur gears were clarified to a considerable extent by a bending fatigue test.

Abstract: This paper presents a study on bending fatigue strength of spur gears in low-cycle range. The calculating methods for adjacent-tooth gaps and the circumferential load, under which adjacent-tooth contacts occur due to the deflections of meshing teeth, are introduced. The validity of these calculating methods is confirmed by carrying out a static loading test. The characteristics of the bending fatigue strength of spur gears in low-cycle range are clarified to a considerable extent by carrying out a bending fatigue test.
