矿井提升钢丝绳因为在腐蚀介质影响的条件下工作,又承受静动载荷作用下的拉、弯、扭应力,所以引起迅速断丝。为了查明技术寿命提高的潜力,曾对苏联煤炭工业部和有色冶金工业部所属的12个联合企业和公司的1400多条钢丝绳质量和可靠性以及换绳原因进行了概率统计分析。综合数据表明:降低钢丝绳寿命的主要因素是,钢丝绳锈蚀和一个捻距内的疲劳断丝超限。然后又用试验评价的方法,即把每
Mine hoisting rope because of the corrosive medium under the conditions of work, but also under static load under the action of the pull, bend, torsional stress, it caused rapid broken wire. In order to ascertain the potential for increased technology life, probabilistic statistical analyzes were conducted on the quality and reliability of more than 1,400 wire ropes and the reasons for changeovers in 12 joint ventures and companies affiliated with the Ministry of Coal Industry and the Ministry of Nonferrous Metals. Comprehensive data shows that the main factors to reduce the life of the wire rope are the wire rope corrosion and the fatigue broken wire within one twist. Then test evaluation method, that is, each
