Comparison of Bending Stress of a Helical Gear for Different Materials and Modules Using AGMA Standards in FEA

Abstract

Gearing is one of the most critical components in mechanical power transmission systems.. This paper explains about the comparison of the geometry of Helical gears for two different modules by modeling and mathematical equations, load distribution at various positions of the contact line and the stress analysis of Helical gears using three-dimensional finite element method. The bending stresses were examined using three-dimensional finite element model.. These stresses of different modules obtained from the finite element analysis were compared and the considerable reduction of weight occurred was found and also the values are compared with the theoretical values. Both results agree very well. This indicates that the finite element method model is accurate.
