Contact Fatigue Analysis of Mine Helical Cylindrical Gear Based on ANSYS Workbench

Abstract:

A general method for calculating contact fatigue strength of Mine helical cylindrical gear was studied in this paper. Both the Solid model and finite element model were created in ANSYS. Based on the fatigue analysis module of the ANSYS Workbench, The contact fatigue strengths of the helical cylindrical gear pair were calculated, and corresponding contact fatigue lives and safety factors of two gears in any meshing position were obtained and shown in contour map. A simulation calculation for a pair of mine helical cylindrical gears was carried out. Simulation results show that calculation of the contact fatigue strength of helical cylindrical gear by this method is more scientific and reasonable than traditional empirical method.
