钢丝绳绳芯的三大 功能
The three main functions of steel wire rope core
1. 结构支撑与应力分散
1. Structural support and stress dispersion
钢丝绳绳芯的首要作用是维持绳体横截面的稳定性。以南通灵达网绳有限公司的麻绳芯为例，其天然纤维的网状结构可均匀分散外层钢丝的挤压应力，避免因局部受力导致的钢丝变形或断丝。实验数据显示，使用麻绳芯的钢丝绳在弯曲半径为绳径10倍的工况下，绳股间接触应力可降低30%以上， 延长使用寿命。
The primary function of the steel wire rope core is to maintain the stability of the cross-section of the rope body. Taking the hemp rope core of Nantong Lingda Mesh Rope Co., Ltd. as an example, its natural fiber mesh structure can evenly disperse the extrusion stress of the outer steel wire, avoiding steel wire deformation or breakage caused by local stress. Experimental data shows that steel wire ropes with hemp core can reduce the contact stress between strands by more than 30% and extend their service life under a bending radius of 10 times the rope diameter.
2. 动态缓冲与振动衰减
2. Dynamic buffering and vibration attenuation
在高频次弯曲或冲击载荷场景（如电梯曳引、港口起重），绳芯的弹性模量成为关键指标。南通灵达网绳有限公司研发的PP芯（聚丙烯纤维芯）通过特殊编织工艺，使绳芯在受力时产生可控形变，吸收并释放冲击能量。例如，在电梯限速器钢丝绳测试中，采用PP芯的绳体可将振动幅度降低45%，减少钢丝疲劳损伤。
In high-frequency bending or impact load scenarios (such as elevator traction and port lifting), the elastic modulus of the rope core becomes a key indicator. The PP core (polypropylene fiber core) developed by Nantong Lingda Net Rope Co., Ltd. undergoes a special weaving process to produce controllable deformation of the rope core when subjected to force, absorbing and releasing impact energy. For example, in the testing of elevator speed limiter steel wire rope, the use of PP core rope body can reduce the vibration amplitude by 45% and reduce steel wire fatigue damage.
3. 润滑储存与防腐屏障
3. Lubrication storage and anti-corrosion barrier
绳芯的纤维空隙构成天然储油腔，南通灵达网绳有限公司通过预浸渍工艺，将复合润滑脂均匀渗透至纤维内部。这种设计不仅可减少钢丝间的摩擦系数（降低至0.08以下），还能在钢丝表面形成致密保护膜，隔绝水汽与腐蚀介质。实测显示，在沿海高湿度环境下，使用含油麻绳芯的钢丝绳锈蚀率较传统产品降低60%。
The fiber gaps in the rope core form a natural oil storage chamber. Nantong Lingda Mesh Rope Co., Ltd. uses pre impregnation technology to evenly penetrate the composite lubricating grease into the fibers. This design not only reduces the friction coefficient between steel wires (to below 0.08), but also forms a dense protective film on the surface of the steel wire, isolating water vapor and corrosive media. Tests have shown that in high humidity environments along the coast, the corrosion rate of steel wire ropes using oil containing hemp rope cores is reduced by 60% compared to traditional products.
