Design and Analysis of Helical Gear using Solid works and ANSYS Softwares

Gears are one of the important parts and that are indispensable for mechanical power transmission systems. There are many stresses that can cause failure in gears in mechanical transmission systems. Bending Stress is one of the most common problems in the gears. Stress analysis is of great importance, because it can predict failure and the optimal design can be achieved. This paper is designed to analyze bending stress using the ANSYS program. The model is drawn by the SOLIDWORKS program, and the analysis is done by using three models of the gears. The face width is changed to compare the effect of bending stress, as well as determining the relationship between the widths of the face and bending stress, and finding the values of stress through the equation of Louise and comparing them with the results of analysis of the ANSYS program.
