7、力计算某一规格的钢丝绳允许承受的最大拉力是有一定限度的 ，超过这个限度, 钢丝绳就会被破坏或拉断，因此在工作中需对钢丝绳的受力进行计算。(一)钢丝绳的破断控力钢丝绳的破断拉力可由表1、2中查出,考虑钢丝绳捻制使每根钢丝受力 不均匀，整根钢丝绳的破断拉力应按下式计算：S =W2 S式中Sp钢丝绳的破断拉力，kN; 工S 钢丝丝绳规格表中提供的钢丝破断拉力的总和，kN;W钢丝捻制不均折减系数,对6X19绳,W =0.85;对6X 37绳,W =0.82; 对 6X 61 绳，W =0.80。但在工作现场，一般缺少图表资料，同时也不要求精确计算，此时 可采用下式（仅为数据估算用，非规范公式）估算钢丝绳的破断拉力：式中Sp钢丝绳的破断拉力，N；d钢丝绳的直径，mm。（二）钢丝绳的安全系数为了保证起重作业的安全，钢丝绳许用拉力只是其破断拉力的几分之一。破断拉力与许用拉力之比为安全系数。下表列出了不同用途钢丝绳的安全系数。为钢丝绳的安全系数使用情况安全系数使用情况安全系数用做缆风绳、拖拉 绳3.5机械驱动起重设备5-6人力驱动起重设备4.5用做吊索（无弯曲）6-7用做捆绑吊索810用做载人升降机14（三）钢丝绳的许用扭力P = Sp/ K式中 P钢丝绳的许用拉力，N;Sp钢丝绳的破断拉力，N;K 钢丝绳的安全系数。例：型号6 >
