摘要
对滚齿加工出的斜齿轮的端面内齿根过渡曲线的形状和曲线方程进行了研究,指出滚刀齿顶圆弧在齿轮端截面内的廓形已变为椭圆弧,在斜齿轮端截面内刀顶对应部分形成的齿根过渡曲线不能用圆弧代替计算,否则将严重影响齿根过渡曲线描绘的准确度,进而影响到在此基础上的齿根强度、加工干涉性、刀具设计、三维造型等一系列分析、研究工作的结论正确性。重点研究分析了滚刀齿顶端截面椭圆弧方程以及对应形成的齿轮端截面内齿根过渡曲线方程的推导和建立,并将研究成果应用于自编的齿轮加工验算软件予以应用和验证。
The shape and equation of tooth root fillet curve in the end face of helix gear by hobbing are studied.It is indicated that the circular arc of hob cutter＇s tip has become elliptical arc surface in the end face of helix gear,so the tooth root fillet curve generated by hob cutter＇s tip couldn＇t be calculated with circular arc,otherwise to do so would influence the veracity of describing tooth root fillet curve,further would influence the correctness of results for a series of analysis and research works based on calculations above,e.g.the strength of tooth root,the interference of process,the design of hob cutter,the 3D forming,etc.The equation of elliptical arc of hob cutter＇s tip in the end face of helix gear is mainly studied and analyzed,and the corresponding equation of tooth root fillet curve generated by the elliptical arc of hob cutter＇s tip in the end face of helix gear is derived and built,and the research results above are applied to the soft for checking computations on processing gear,which written by author,and are verified.
