针对大模数齿轮高阶修形齿廓的滚齿加工,不同的滚刀前角的滚刀刃口曲线不同,对齿轮的齿廓精度影响较大。根据滚齿加工的2自由度的齿面包络原理,计算了滚刀基蜗杆与齿面的滚切接触迹线,通过旋转投影,计算了不同前角的滚刀刃口曲线,对比了刃口曲线的形状和倾角随滚刀前角的变化情况,为滚刀刃口曲线的设计和检测提供了依据,并通过修形齿廓的滚切加工和齿廓检测验证了上述设计方法。
In the process of large module gear hobbing of high-order modification tooth profile
the cutting edge curve is different according to the variation of rake angle
which has a great influence on tooth profile accuracy. Thus the 2-degree envelope method is applied to the gear hobbing process to obtain the hobbing contact trace between the tooth surface and the base worm of the hobbing cutter. The cutting edge curve is calculated based on the different rake angles of the hobbing cutter. The shape and the slope of the cutting edge are analyzed
which provides the reference for the design and measurement of hobbing cutter edge. In the end
a modified gear profile is hobbed and measured to verify the above design method.
