A solver of ideal tooth profile modification curve for cylindrical gearing is proposed. The coupled thermo-elastic contact finite element method has been applied to analyze the meshing stiffness of gear -pair. In this analysis, many factors such as load share between teeth, pressure distribution on tooth profile, the friction effect, heat transfer and the production error have been taken into consideration. In order to determine the proper stiffness variation the deformation of gear tooth profile have been described exactly as far as possible. Based on the research results the ideal modification curve can be obtained by numerical fitting.
