摘要
为提高电梯用钢丝绳疲劳寿命 ,主要采取如下措施 :采取 8× 19S外粗式线接触结构 ;控制钢丝含碳量 ,外层钢丝用 45号钢生产 ,股内层钢丝用 6 5号钢生产 ,通过热处理工艺监控可使钢丝获得高疲劳寿命的组织 ;使用剑麻麻芯 ,用德国产油脂 ;用带预张拉装置的成绳机捻绳 ,通过以上措施可使疲劳寿命大大提高 ,达 6
In order to improve the antifatigue life of wire rope for lift,some measures are adopted,which are to use wide in external type 8×19S linear contact lay structure,to control carbon content of steel wire,to make outer wire with 45 # steel and inner wire in strand with 65 # steel,to monitor heat treatment technology so as to get the microstructure with long antifatigue life of steel wire,to use sisal hemp rope core and oil made in Germany,to twist rope with rope making machine bearing pre stretching unit After these measures have been adopted,the antifatigue life of rope can be greatly increased,which can reach 60×10 4 times
