摘要
螺杆是摆线螺杆泵中最重要零件之一。如何经济修整铲磨螺杆成形铣刀的砂轮是一个急待解决的问题。本文介绍了铲磨螺杆成形铣刀的新工艺。利用曲线逼近原理,用扁圆曲线段分段逼近铲磨铣刀齿形曲线的砂轮轴剖面型线,修整器结构简单,调整方便,通用性好。现场使用证明,此工艺为制造螺杆成形铣刀提供了一种经济有效的方法。
The grinding of the cycloid screw forming cutter is thekey process of machining the cutter. A new process of grinding the cut-ter is developed in this paper. By means of the approach principle, weestablish the mathematic model in which a degenerate circle is used toapproach the axial cross-section curves of the grinding wheel of grind-ing the cutter, and analyze the main process parameters of influencingthe ground quality. Through experiments, this process is proved to bean efficient and economical method.
