摘　　要：建立刀片在工作过程中的受力模型,得出刀片切土角和安装角的合理选取范围。通过分析螺旋线的形成原理,建立了锥形面螺旋线的统一方程,并对圆锥螺旋钻尖的翼片刀刃部分进行了优化分析。The force model of blades in operation is created, which shows reasonable selection range of cut-in angles and installation angles of blades. Through the analysis of the formation principle of helical curves, the uniform equation of taper surface helical curves is established and the optimization analysis is made of the screw wing cutting edge of the taper-spiral auger＇s tip.
