影响钢丝绳使用寿命的因素及改进措施

从钢丝绳制造和使用2个方面分析影响钢丝绳使用寿命的各种因素.制造过程影响钢丝绳使用寿命的因素:绳芯支撑不足、缺丝、凸丝、钢丝绳有应力；改进措施:金属芯直径应比主股直径大15％～20％,修补钢丝绳中断丝,合理使用变形器,钢丝张力保持一致,中心丝放大量约0.15 mm,股的变形率为85％ ～ 95％.使用过程影响钢丝绳使用...

Factors and improvement measures of effecting steel wire rope' s service life

To analyse all reasons that effect steel wire rope＇ s service life through steel wire rope＇ s manufacture and usage. The reason of manufacture process effects steel wire rope＇s service life is ：rope core does not have enough stand, lacking of wire, bulge wire, steel wire rope has stress ; improving measures ： the diameter of metal core should bigger than main strand as 15% - 20%, to mend the broken wire in the steel wire rope, to use deformer reasonably, and tension of steel wire ropes stay the same, central wire＇ s enlarging data is 0.15 mm, strand＇ s deformation rate is 85% -95%. The factors of effecting steel wire rope＇s service life during process are：broken wire, broken strand, deforming; improving measure： to cut the broken part and re-set up, to check rope wheel＇ s protector and guide pulley, the radius of sheave＇ s groove should be 0. 525 -0. 550 times of steel wire rope＇ s nominal diameter, steel wire rope should keep a normal raising speed, do not randomly pick up rope in case of making a knot, to avoid of mechanical extrusion, overloading and steel wire rope＇ s jumping.
