Experimental Tests and FEM Simulations of Flank Breakage on Tooth of Gears with Respect to Different Nitrided Depths

Abstract:

This article deals with the reasons for gear failure - Flank breakage on tooth of spur gears with helical and straight involute gears. Gear flank breakage can be observed on edge zone-hardened gears. The creation of flank and tooth breakage and FEM simulation of flank breakage on tooth are described in this article. In the article are also described and short photo documentation from real load tests on mechanically closed stand for testing of gearing with helical gears and different nitrided depth.
