Abstract
When the Finite Element Method is applied to the stress analysis of meshing tooth pair, a large difference between dimensions of finite elements and tooth flank modification should be one of the main issues. In addition, it is very difficult for FEM to solve a contact problem in meshing part. A new element for representing boundary condition at contact area, a Tooth Flank Film Element, was proposed as a solution to the issues. Contact area is supposed, then the Tooth Flank Film Element enables distributed loads to be given to the area. A CAE system specialized for static stress analysis of cylindrical gear pair has been developed using the Tooth Flank Film Element. The present paper describes the developed CAE system. Because the CAE system is specialized for cylindrical gear pair, it is very easy to construct the analytical model which can include tooth flank modification. It is confirmed that the calculated minimum value of minimum principal stress and maximum value of maximum principal stress should be valid by comparison with tooth flank contact stress and tooth root bending stress calculated through ISO 6336.
