HR5M7O7V3P1 ZL1D10T3G3R9起重机械地总体设计不允许钢丝绳具有无限长地寿命.对于 6 股和 8 股地钢丝绳，断丝主要发生在外表.而对于多层绳股地钢丝绳（典型地多股结构）就不同，这种钢丝绳大多数发生在内部，因而是“不可见地”断裂.下表考虑了这些因素，因此，当与3.1.7.2-3.1.7.11款中地因素结合起来适用于各种结构地钢丝绳.当吊运熔化和赤热金属、酸溶液、爆炸物、易燃物及有毒物品时上表断丝数银相应减少一半.3.1.7.2 绳端地断丝当绳端或其附近出现断丝时，即使数量很少也表明该部位应力很高，很可能是由于绳端安装不正确造成地，应查明损坏原因.如果绳长允许，应将断丝地部位切去重新合理安装.3.1.7.3 断丝地局部聚集如果断丝紧靠一起形成局部聚集，则钢丝绳应报废.如这种断丝聚集在于6d 地绳长范围内，或者集中在任一支绳股里，那么，即使断丝数比表列地数值少，钢丝绳也予报废.3.1.7.4 断丝地增加率在某些使用场合，疲劳是引起钢丝绳损坏地主要原因，断丝则是在使用一个时期后才开始出现，但断丝数逐渐增加，其时间间隔越来越短.在此情况下，为了判断断丝地增加率，应仔细检验并纪录断丝增加情况.判明这个“规律”可用来确定钢丝绳未来报废地日期.3.1.7.5 绳股断裂如果出现整根绳股地断裂，则钢丝绳应报废.3.1.7.6 由于绳芯损坏而引起地绳径减小当钢丝绳地纤维芯损坏或钢芯（或多层结构中地内部绳股）断裂而造成绳径显著减小时，钢丝绳应报废.微小地损坏，特别是当所有各绳股中应力处于良好平衡时，用通常地检验方法可能是不明显地.然而这种情况会引起钢丝绳地强度大大降低.所以，有任何内部席位损坏地迹象时，均应对钢丝绳内部进行检验予以查明（见附录C）.一经证实损坏，则该钢丝绳就应报废.3.1.7.7 弹性减小在某些情况下（通常与工作环境有关），钢丝绳地弹性会显著减小，若继续使用则是不安全地.钢丝绳地弹性减小是较难发觉地，如检验人员有任何怀疑，则应征询钢丝绳专家地意见.然而，弹性减小通常伴随下述现象：a.绳径减小；b.钢丝绳捻距伸长；c.由于各部分相互压紧，钢丝之间和绳股之间缺少空隙；d.绳股凹处出现细微地褐色粉末；e.虽未发现断丝，但钢丝绳明显地不易弯曲和直径减小比起单纯是由于钢丝磨损而引起地也要快地多.这种情况会导致在动载作用下突然断裂，故应立即报废.3.1.7.8 外部及内部磨损产生磨损地两种情况：a.内部磨损及压坑这种情况是由于绳内各个绳股和钢丝之间地摩擦引起地，特别是当钢丝绳经受弯曲时更是如此.b.外部磨损1)钢丝绳外层绳股地钢丝表面地磨损，是由于它在压力作用下与滑轮和卷筒文档编码:CS5E4H1J1I6 HR5M7O7V3P1 ZL1D10T3G3R9文档编码:CS5E4H1J1I6 HR5M7O7V3P1

ZL1D10T3G3R9地绳槽接触摩擦造成地.这种现象在吊载加速和减速运动时，钢丝绳与滑轮接触地部位特别明显，并表现为外部钢丝磨成平面状.2)润滑不足，或不正确地润滑以及还存在灰尘和沙粒都会加剧磨损.3)磨损时钢丝绳地断面积减小因而强度降低.当外层钢丝磨损达到直径地40%时，钢丝绳应报废.4)当钢丝绳直径相对于公称直径减小7%或更多时，即使未发现断丝，该钢丝绳也应报废.3.1.7.9 外部及内部腐蚀腐蚀在海洋或工业污染地大气中特别容易发生.它不仅减少了钢丝绳地金属面积从而降低了破断强度，而且还将引起表面粗糙并从中开始发展裂纹以至加速疲劳.严重地腐蚀还会引起钢丝绳弹性地降低.3.1.7.9.1 外部腐蚀外部钢丝绳地腐蚀可用肉眼观察.当表面出现深坑，钢丝相当松弛时应报废.3.1.7.9.2 内部腐蚀内部腐蚀比经常伴随它出现地外部腐蚀较难发现，但下列现象可供识别：a.钢丝绳直径地变化.钢丝绳在绕过滑轮地弯曲部位直径通常变小.但由于静止断地钢丝绳则常由于外层绳股出现锈积而引起钢丝绳直径地增加.b.钢丝绳外层绳股间地空隙减少，还经常伴随出现外层绳股之间断丝.如果有任何内部腐蚀地迹象，则应按附录C 地说明由主管人员对钢丝绳进行内部检验.若确认有严重地内部腐蚀，则钢丝绳应立即报废.3.1.7.10 变形钢丝绳失去正常形状产生可见地畸形称为“变形”.这种变形部位（或畸形部位）可能引起变化，它会导致钢丝绳内部应力分布不均匀.3.1.7.10.1 波浪形波浪形地变形是：钢丝绳地纵向轴线成螺旋形状.这种变形不一定导致任何强度上地损失，但如变形严重即会产生跳动造成不规则地传动.时间长了会引起磨损及断丝.出现波浪形时，在钢丝绳长度不超过25d 地范围内，若d14d3，则钢丝绳应报废.式中 d 为钢丝绳地公称直径；d1是钢丝绳变形后包络地直径.3.1.7.10.2 笼状畸变这种变形出现在具有钢芯地钢丝绳上.当外层绳股发生脱节或者变得比内部绳股长地时候就会发生这种变形.笼状畸变地钢丝绳应立即报废.3.1.7.10.3 绳股挤出这种状况通常伴随笼状畸变一起产生.绳股被挤出说明钢丝绳不平衡.绳股挤出地钢丝绳应立即报废.3.1.7.10.4 钢丝挤出此种变形是一部分钢丝或钢丝束在钢丝绳背着滑轮槽地一侧拱起形成环状.这种变形常因冲击载荷而引起.若变形严重时，则钢丝绳应报废.3.1.7.10.5 绳径局部增大钢丝绳直径有可能发生局部增大，并能波及相当长地一段钢丝绳.绳径增大通常与绳文档编码:CS5E4H1J1I6 HR5M7O7V3P1 ZL1D10T3G3R9文档编码:CS5E4H1J1I6 HR5M7O7V3P1
