| Summary: | A method for designing tooth surface of spiral bevel gears based on quantitative mismatch modification is proposed in this study. Firstly, the mathematical relationship between modification quantity, modification coefficient and structural parameters of tooth surface is revealed. Then a target tooth surface oriented by mesh performance is established according to conjugate tooth surface and second-order modification surface. The tooth surface deviation correction model between target tooth surface and theory tooth surface is constructed, and the corrections of machine setting parameters are calculated. A numerical example is taken to verify, the corresponding modification coefficients are calculated quickly according to modification quantity, and the problem of blind selection of modification coefficients is solved. The experimental results are consistent with the theoretical analysis, and the mesh performance is improved. Experiments verify the effectiveness of the proposed method, and the method is also suitable for tooth surface modification of other gears. |
