新型平顶圆弧齿同步带带轮滚刀齿廓的研究

A Study on Hobbing Outline of New Type ARC Toothed Belt Pulley

将带轮和滚刀的相对运动归结为带轮节圆沿滚刀节线所作的相对运动，运用包络原理分别推导出由带轮齿廓确定的刀具齿廓方程和由刀具齿廓确定的带轮齿廓方程。文中以实际加工出的带轮齿廓与理论齿廓的齿向误差最小为目标，讨论了带轮滚刀齿廓的优化设计方法和结果。

In this paper the relative motion of belt pulley with hob is regarded as the relativemotion of the pitch circle of belt pulley along hob piteh line.Applying the wrapping Prindple,the tool outline equation defined by belt pulley outline and the belt pulley outlineequation defined by tool outline are derived respectively.In order to minimize the tooth direction error between practical processing belt pulley outline and theoretical outline,the optimal de sign method and results of hob outline of belt pulley are discussed.
