| 摘 要： | 提出了用于外啮合齿轮珩齿加工的一种CBN径向珩齿刀,其基体的设计理论及其渐开线拟合是关键技术。通过应用空间啮合原理,推导出了斜齿珩齿刀与直齿齿轮的啮合方程,得到了这种珩齿刀的端面理论廓形,分析表明,此类刀具的端面理论廓形并不是渐开线;对其廓形进行了渐开线拟合,采用最优化方法计算了不同轴交角的渐开线参数,计算表明,把砂轮轴向廓形整修成具有一定压力角的直边,就可以磨出所拟合的全部渐开线刀齿面。加工珩齿刀基体时,根据修正后的压力角调整机床安装角,即可磨出符合要求的珩齿刀的基体。本研究为珩齿加工刀具提供了新的设计制造方法,对实际生产具有指导意义。

| Abstract: | Cubic boron nitride(CBN) plunge gear-honing cutter for processing external gear was presented in this paper,for which the design theory of the matrix and involutes' fitting were the key technology.Based on the spatial meshing principle,the meshing equation between helical gear-honing cutter and straight-tooth gear was derived.As a result the end's theoretical profile of plunge gear-honing cutter was obtained.It is shown that such end's theoretical profile is not involutes.The involutes' fitting was done on ... |
