Abstract

The main factors that cause the failure of gears are the bending stress and contact stress of the gear tooth. Stress analysis has been a key area of research to minimize failure and optimize design. This paper gives a finite element model for investigation of the stresses in the tooth during the meshing of gears. The model involves the involute profile of a spur gear for material Steel 15Ni2Cr1Mo28. The geometrical parameters, such as the face width and module, are considered important for the variation of stresses in the design of gears. Using modeling software, 3-D models for different modules in spur gears were generated, and the simulation was performed using ANSYS to estimate the bending and contact stresses. The Hertzian equation is used to calculate the contact stress. The results of the theoretical stress values are compared with the stress values from the finite element analysis.
