非渐开线变厚齿轮修形方法的研究

In order to manufacture noninvolute beveloid gears with the existing machine tools, a new way of gear tooth modification is developed based on the space engagement theory for the first time in this paper. By improving the wheel gear grinder of large plane grinding, the paper has provided the tooth modification method of manufacturing noninvolute beveloid gears. By using hyperbolas to fit axial curves, considering the maximal error of the fitting curves as the objective function, the optimal fitting hyperbola is obtained and the maximal error of fitting curves is minimal after optimization. Finally, an example and its calculation results are presented.
