Analysis of Profile Shift Factor's Effect on Bending Stress of Spur gears Using The Finite Element Method

Gears are used for motion and power transmission in various systems. The main factor that causes the gears system failure is the bending stress and contact stress. This paper is about studying the effect of the Profile Shift Factor x on the bending stress generated on the root of the spur gear teeth pair, to minimize the stress and optimize the design. Three cases of Profile Shift Factor are chosen in this work, $\mathrm{x}=0,\ \mathrm{x}=0.1$, and $\mathrm{x}=0.2$. The theoretical results of bending stress are calculated using ISO standard equation according to the LEWIS theory and confirmed by Finite Element Method (EFM) with ANSYS Workbench software. The three geometry models are generated on Solidworks.
