Research on Bending Fatigue of Cylindrical Gear Based on ANSYS Workbench

Abstract:

Based on the bending fatigue properties of cylindrical gear pair, the worst meshing positions on driving and driven gears are respectively determined, the corresponding S-N curve for bending fatigue and loading spectrum of tooth root bending stress are obtained. Then a method for analyzing the bending fatigue of the cylindrical gear by ANSYS Workbench is studied and the simulation is carried out. Different from the traditional methods, the bending fatigue characteristic parameters such as safety coefficients and fatigue sensitive coefficients for every part of the tooth can be precisely calculated by finite element method. It provides an important basis for reliability design and structural optimization of the cylindrical gear pair.
