(一)引言多钢绳提升机,由于它的优点显著,故自问世以来发展迅速。我国从1958年安装使用第一台多绳提升机以来,现已普遍推广使用,但是,多绳摩擦轮提升机的理论研究还远落后于实际生产。主导轮是多绳提升机的主要部件之一,实际结构有多种多样。关于主导轮的计算,国内外的研究者都首先注意到轮壳的强度。即当钢绳总载荷为S_(max)或每根钢绳的载荷为T时,
(A) Introduction Multi-rope hoist, because of its significant advantages, it has developed rapidly since its inception. Since 1958, China has installed and operated the first multi-rope hoist, it has been widely used. However, the theoretical research on the multi-rope friction hoist lags far behind the actual production. The main wheel is one of the main components of a multi-rope hoist, the actual structure of a wide variety. With regard to the calculation of the leading wheel, researchers all over the world have first noticed the strength of the wheel shell. That is, when the total load of steel rope is S max or the load of each steel rope is T,
