齿轮滚刀铲磨干涉的计算机辅助计算

Computer Aided Calculation of Gear Hob about Relief Grinding Interference

铲磨齿轮滚刀时,为了保证磨光长度,有时会产生干涉现象。本文在研究盘形砂轮铲磨齿轮滚刀的基础上,应用计算机辅助计算方法,计算已知砂轮直径的情况下,铲磨齿轮滚刀时是否发生干涉现象;或对齿轮滚刀进行铲磨时,计算最大许用砂轮直径与最小许用砂轮直径。此方法不但比作图法精确可靠、省时省力,而且比人工解析计算方便快捷,为齿轮滚刀的计算机辅助设计与制造奠定了良好的基础。

In order to ensure the polishing length of hobshovel grinding, it maybe produce interference, this paper studiesthe di sc-shaped grinding wheel shovel hob, on the one handwhen known grinding wheel diameter that using computer-aidedcalculation method to test whether the interference occurs, on theother hand to calculate the maximum allowable relief grindingwheel diameter and the minimum allowable relief grinding wheeldiameter. This method is not only accurate and reliable thanthe mapping, time-saving and convenient than doing analyticcalculation laid a good foundation for computer-aided design andmanufacturing of gear hob.
