捻距
lay length
n IonJU捻距(l ay length)在抢股或合绳时，钢丝围绕股芯或绳股围绕绳芯旋转一周(3600)的起止点间的直线距离，如图所示。在捻制过程中，钢丝或绳股由捻制设备的机身带动作匀速圆周转动，在捻合的同时又被牵引轮带动作匀速直线运动，即成为绳股(简称股)或钢丝绳，钢丝在股中和股在钢丝绳中呈现圆柱螺旋线状态。因此，捻距的表达式除了在捻角中所表达的之外，依据捻制设备的运动状态还可由下式表示: t一 103竺 n式中t为捻距，mm;V为线速度，mm/min;n为机身的转速，r/min。在实际生产中，捻距还用绳股直径(简称股径)或钢丝绳直径(简称绳径)的倍数来表示，即:t一kd和T一KD，式中k和K为绳股及钢丝绳捻距倍数;d和D为股径及绳径，mm;t和T为股及钢~~麟夔蠢黔 粉 捻距示意图丝绳的捻距，mm。 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。捻距与捻角的正切互成反比关系。由于捻角不便于检测，捻距便于检测，因此在实际生产中，捻距是一项主要的工艺指标和检验指标，在钢丝绳的有关标准中有明确的规定。 (邱煌明)
