摘　　要：针对面铣螺旋锥齿轮的设计和制造,建立了基于自由曲面机床的加工方法的数学模型,在自由曲面机床上采用工件轴固定的方法完成螺旋锥齿轮铣削的主动设计和制造。以啮合性能参数为输入变量,建立了齿轮啮合的数学模型,并根据设计的接触属性对齿轮齿面进行了主动设计。除了传统方法控制的每个小齿轮侧面平均接触点的一阶和二阶参数外,该方法还可以同时保证小齿轮常用驱动侧面上的每个接触路径点,避免了工件轴运动精度差造成的误差和制造难度。最后,通过齿面接触分析(TCA)和滚动试验对该方法进行了有效验证。Aiming at the design and manufacture of face milling spiral bevel gear,the mathematical model of machining method based on free-form surface machine tool is established.The active design and manufacture of spiral bevel gear milling are com⁃pleted by fixing the workpiece shaft on the free-form surface machine tool.Taking the meshing performance parameters as the in⁃put variables,the mathematical model of gear meshing is established,and the gear tooth surface is actively designed according to the designed contact attributes.In addition to the first-order and second-order parameters of the average contact point on the side of each pinion controlled by the traditional method,this method can also ensure each contact path point on the common driv⁃ing side of the pinion at the same time,avoiding the error and manufacturing difficulty caused by the poor motion accuracy of the workpiece shaft.Finally,the method is verified by tooth contact analysis(TCA)and rolling test.
