摘要
以弧齿锥齿轮齿面修形设计为研究对象,提出了一种基于定量失配修形的齿面设计方法。揭示了齿面修形量、修形系数与齿面结构参数间的数学关系,在完全共轭齿面的基础上引入2阶修形曲面,建立了以齿面接触性能为导向的目标齿面;建立目标齿面与理论齿面间的齿面偏差修正模型,求解了机床调整加工参数修正量。以一对弧齿锥齿轮副为例进行验证,根据齿面修形量快速计算对应的修形系数,解决了修形系数盲目选取的问题。修形后齿面接触性能得到改善,切齿实验结果与理论分析结果一致。实验验证了提出的基于定量失配修形的弧齿锥齿轮齿面设计方法的有效性,该方法同样适用于其他齿轮齿面的修形设计。
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.
