在钢绳绕过导向轮时,例如矿井提升装置的井架天轮、架空索道的从动轮等,如钢绳张力为P,则其对轮缘的均布压力为q=P/R,R为轮子半径,如图1a所示,该压力引起的轮缘和轮辐的内力计算是比较复杂的,已经有过一些简单的近似计算公式。本人也曾在“化工矿山技术”杂志上发表过一篇文章,认为只要把轮缘展直,把它看成是一根无限长的连续 For example, when the steel rope passes around the guide wheels, such as the derrick day wheel of the mine hoist, the driven wheel of the ropeway, etc., if the steel wire tension is P, then the uniform pressure on the rims is q = P / R, The radius of the wheel, as shown in Figure 1a, is more complicated than the calculation of the internal forces of the rim and spoke caused by this pressure. There have been some simple approximate formulas. I also published an article in Chemical Mines Technology magazine that thinks that as long as the rim is straight, it can be regarded as an infinite continuous
