Description

单层四股不旋转钢丝绳 
技术领域
本实用新型涉及一种钢丝绳结构，具体为一种单层四股不旋转钢丝绳。 
背景技术
在重型移动式履带起重机上使用的钢丝绳，一般为35W×7面接触钢丝绳。其捻制方法是：中心股为1×7普通股，第一层为6根1×7面接触股，第二层为6根大的和6根小的1×7面接触股相间交替分布，此18根股为一次捻成作为绳芯；第三层为16根1×7面接触股，包裹在绳芯的外面，且与绳芯的捻向相反。这样，钢丝绳在运转中，绳芯和外层股产生的扭矩相互抵消，从而达到抗旋转的目的。这种钢丝绳具有抗旋转和良好的柔韧性等特性，其强度一般在1960Mpa以上。它的使用要求非常苛刻，一年内钢丝绳不得有断丝、扭结、缩径、磨损超标等非正常损坏。 
35W×7面接触钢丝绳主要存在以下四个缺点：1.价格太高，平均价格在4万元/吨以上；2.由于钢丝绳全部为钢丝，钢丝绳的内部存油量不足；3.使用寿命长短不一，寿命短的不足半年，与供应商协商赔偿往往难以达成一致；4.钢丝绳结构不稳定，在多层缠绕中容易难绳、散股和绳芯挤出等早期损坏。 
发明内容
本实用新型的目的在于针对35W×7面接触钢丝绳的缺陷，提供一种可以替代35W×7面接触钢丝绳，且性能更加优良的单层四股不旋转钢丝绳。 
本实用新型的技术方案如下：一种单层四股不旋转钢丝绳，由四根经单独 压实的外层股和一根绳芯组成，每根外层股的捻距为股直径的6.6～7.0倍，整体钢丝绳的捻距为绳直径的8.6～9.0倍。 
进一步，如上所述的单层四股不旋转钢丝绳，其中，每根外层股在单独压实时的压缩率为6％～12％。 
本实用新型的有益效果如下：本实用新型所提供的单层四股不旋转钢丝绳外表面平整圆滑，提高了钢丝绳与滑轮、卷筒、托轮的接触面积，减少了应力集中，减少了钢丝绳提前断丝导致报废的几率，确保了钢丝绳的使用寿命；绳芯采用含油聚合物高分子材料(如尼龙-66、尼龙-6、聚丙烯等)，确保钢丝绳的内部润滑；钢丝绳的制造成本相对于35W×7面接触钢丝绳明显减少，从而降低了销售价格；采用合理的参数设计，确保钢丝绳的抗旋转性与35W×7面接触钢丝绳相当。 
附图说明
图1为本实用新型的横截面示意图； 
图2为本实用新型的侧面示意图。 
具体实施方式
下面结合附图和实施例对本实用新型进行详细的描述。 
不旋转钢丝绳是指钢丝绳在竖直悬吊重物工作状态时，不会产生围绕自身轴线旋转的一种性能。钢丝绳的不旋转性能对使用来说，有着极为重要的意义。在新建矿井时凿井、各种起重机提升重物等等使用场合下，都要求钢丝绳不旋转，才能正常工作。如果钢丝绳旋转，会影响工作效率以及财产生命安全，此外对钢丝绳本身来说，由于旋转，会不断地降低疲劳性能，而影响钢丝绳的使 用寿命。对于单层股钢丝绳来说，应该缩小股的捻距，而且增大绳的捻距，并尽量减少股数，将股制成异形股，以便增大股的力矩之和来抵消绳的力矩，从而满足不旋转的要求。 
如图1、图2所示，本实用新型所提供的单层四股不旋转钢丝绳，由四根经单独压实的外层股1和一根含油聚合物高分子材料的绳芯2经捻制锻打而成，聚合物高分子材料可选用如尼龙-66、尼龙-6、聚丙烯等。每根外层股的捻距为股直径的6.6～7.0倍，如6.6倍、6.8倍、7.0倍；整体钢丝绳的捻距为绳直径的8.6～9.0倍，如8.6倍、8.8倍、9.0倍。捻距是钢丝绳的一项极其重要的捻制工艺参数。对钢丝绳的结构性能和产量等方面有着重大影响，也是捻制设备的一项主要技术参数。捻距的定义如下：在捻股或合绳时，钢丝围绕股芯或绳股围绕绳芯旋转一周(360°)的起止点间的直线距离。 
上述单层四股不旋转钢丝绳的四根外层股1是经过单独压实的异形股，采用WS(36)结构绳股进行压实加工，每根外层股在单独压实时的压缩率为6％～12％。捻制成的钢丝绳再经过锻打二次压实，锻打时的压缩率为15％～25％，使之具有良好的耐磨性并增加与之接触机件的接触面积。同时利用四股绳固有的抗旋转特性，减小股的捻距(6.6～7.0倍股直径)，加大绳的捻距(8.6～9.0倍绳直径)，使之达到抗旋转的目的。
