Based on ANSYS finite element analysis of cylinder involute tooth gear

In this paper, a cylinder involute tooth gear model is built in AutoCAD2000 software, then analyzes its stress through finite element analysis, calculate the gear's maximal stress and its maximal strain, and the result shows that it is proximate to the truth through the element analysis. So we can see the invalidation of the gear according to the analysis. It is convenient to check the bending strength of the root of the gear and the fatigue contact strength of the face of the gear, which is benefit to make deep research of mechanic quality during the process of gear-driving and support the theory basis of the optimal design of gears.
