摘要
对正圆柱螺旋面的计算法公式进行了探讨,分析了产生误差的原因;考虑到拉伸变形这一主要因素,介绍了1种经验取值的方法来修正螺旋输送机轴叶片的下料尺寸,避免了胚料直径偏大。修正后误差小于1.1%,提高了螺旋机轴的制作精度。
The calculation formula for positive column helicoid was discussed and the reasons for error were analyzed. Considering the major factor extension and distortion,this paper introduced an empirical value method to modify the cutting off dimensions of spiral conveyor leaf,avoided the too large of diameter of raw material. The error was less than 1.1% after it was modified,and the production precision of spiral conveyor was improved.
