摘要
本文探讨了正圆柱螺旋面的展开方法及其对实际导程的影响。采用了拉格朗日中值定理导出的计算公式,在计算机上运算及绘制出螺旋面展开图。运用本文推荐的计算公式绘制展开图,将有利于制造螺旋输送器叶片。
Method is approached for expanding cylindrical spiral surface and its effect on actual lead. New calculating formula is derived from Lagranigian mean value theorem to plot the expanded graph.And program compiled in BASIC Language. The plotting of expanded graph from auger surface parameters is realized on IBM-PC microcomputer. With expanded graph thus plotted,the manufacture will be facilitated of blades for spiral conveyor.
