航空弧齿锥齿轮磨削齿面的主动优化设计

为了实现设计要求的啮合性能,采用数控磨齿方式加工弧齿锥齿轮副。加工小轮时的机床位置设置和小轮与摇台之间的相对运动关系是数控磨齿的关键。为此,借助局部综合法实现齿面参考点处指定啮合性能的磨齿参数的主动设计,并通过优化小轮的各阶变性系数改变小轮与摇台之间的相对运动关系,以保证齿面接触印痕和传动误差曲线均满足设计要求。对某航空弧齿锥齿轮进行了齿面主动优化设计,证明了上述方法是有效的。

A Better Active Design for Optimizing Grinding Parameters of Aviation Spiral Bevel Gears

Aim.The introduction of the full paper reviews a number of papers in the open literature and then,in its sixth and final paragraph,outlines our active design which we believe is better than what is obtainable with the methods in the papers reviewed.Sections 1 through 4 explain our active design.Section 2 performs the active design of the digitized grinding parameters of spiral bevel gears with the local synthesis method to coincide with the predetermined meshing performances at the mean contact point of too...
