摘要：应用空间解析几何分析得出，纺纱时在钢领上的钢丝圈平面MJA通过点A——钢丝圈与钢领接触点，在坐标平面上画出迹线Au、Aw、Av。线Au在水平面上，则钢丝圈外脚超前；Aw在切平面上，则钢丝圈整体前倾；Av在垂直平面上，则钢丝圈外脚下沉。钢丝圈外脚下沉实质上是钢丝圈外倾，它导致钢丝圈外脚尖与钢领颈壁的间隙减小、甚至碰擦。钢丝圈外倾伴随着钢丝圈质心高度下降，分析力三角形到完成动态图，可列出钢丝圈外倾角τ′和质心纵坐标a的计算式，进而解出钢丝圈质心位置角δ和其它参数，在实用上钢丝圈外倾角τ′必须远离τ′_m，为此我们须注意圈径A₀M₀的取值。

Abstract:By solid analytical geometry obtain,The traveler-plane MJA on ring during spinning pass through point A——contacted by traveler with ring,and draw out a path-line u,w,v on coordinate plane correspondingly.On the ring plane the line u denotes the outside edge of traveler must lead the inside edge;On the tangentical plane the line w denotes forward-tilting of whole body of the traveler.On the axial plane the line v denotes drop down of outside toe of the traveler.With it there is virtually a outward-tilting of the traveler,and resulting in clearance decreasing between traveler and ring,even to crash each other.The outward-tilting of the traveler accompany with lower mass centre.By analysis force-triangle to finish kinetic-form diagram can to list formula for outward-tilting angle τ′ and vertical coordinate a of mass-centre.Put it into formula derived from mechanic analysis, Could find the position angle δ of mass-centre and other parameter. On practice, the outward-tilting angle τ′ should be more less than τ′_m,so we must pay a attention to select the magnitude of line A₀M₀.
