钢丝绳扭转与其结构参数有关,能使提升系统钢丝绳产生扭绞而中断其有效使用。扭转效应强弱采用扭矩系数来描述,对扭矩系数进行定义,指出影响钢丝绳扭矩系数的因素是捻角、捻制圆半径和捻制方向。推导6×7-WSC类钢丝绳扭矩系数的计算公式,钢丝绳中所有扭矩系数的代数和为整个钢丝绳的扭矩系数。以6×7-WSC—12钢丝绳为例,计算出其扭矩系数为+1.300 002 422,不同具体参数下的扭矩系数可以按此分步计算。验证后认为相同工艺参数生产的同结构钢丝绳扭矩系数相同。
Wire rope torsion and its structural parameters, can make the lifting system wire rope twist and interrupt its effective use. The torsional effect strength is described by the torque coefficient, and the torque coefficient is defined. The factors affecting the torque coefficient of the wire rope are the twist angle, the radius of the twisting circle and the twisting direction. The calculation formula of torque coefficient of 6 × 7-WSC wire rope is deduced. The algebra of all torque coefficients in wire rope and the torque coefficient of the whole wire rope are deduced. Taking 6 × 7-WSC-12 wire rope as an example, its torque coefficient is calculated as +1.300 002 422. The torque coefficients under different specific parameters can be calculated in this step-by-step manner. After verification that the same process parameters of the same production structure of steel wire rope torque coefficient.
