一、前言阿基米德蜗轮滚刀,由于它的齿形在轴向剖面中为直线,制造简单,测量方便,已被广泛应用。当滚刀的分圆柱螺纹升角λ≥5°时,则滚刀前刀面的出屑槽一般应为螺旋槽。在制造时,为了保证蜗轮滚刀的刀齿在热处理后有正确齿形,通常是采用盘形砂轮在铲磨机上进行铲磨而获得。滚刀侧铲面的形成过程是砂轮与磨削表面无瞬心包络过程,因此在铲磨时,由于砂轮与滚刀中心距的变小,导致砂轮与滚刀侧铲面的空间接触线发生变化,为了得到合格的滚刀齿形,必须将砂轮锥面
I. Introduction Archimedes worm gear hob, because of its profile in the axial section of a straight line, easy to manufacture, easy measurement, has been widely used. When the sub-cylinder hob thread angle λ ≥ 5 °, then the rake face of the hob should generally spiral groove. In manufacturing, in order to ensure that the worm gear hob teeth have the correct profile after heat treatment, usually using disc-shaped grinding wheel in the shovel grinding machine obtained. Hob-side surface of the formation process is no instantaneous grinding wheel grinding surface and the envelope process, so shoveling, the grinding wheel and hob center distance becomes smaller, resulting in wheel and hob side of the shovel space contact line Change, in order to get qualified hob tooth shape, the wheel cone must be
