摘要:桥式起重机钢丝绳损坏特殊情况分析....……

起重机钢丝绳损坏特殊情况分析 ,有如下几点,这里给你讲明白,对你有好处的。正常设计维护的起重机其钢丝绳应有合理使用寿命,但钢丝绳可能由于过度磨损和腐蚀而过早损坏。对钢丝绳的适当润滑可以解决该问题。钢丝绳也可能由于机械性或结构损坏而过早报废,此时只有改进起重机和钢丝绳结构及使用才能凑效。文章首先阐述钢丝绳弯曲疲劳的机理,然后分析多层缠绕的螺旋卷筒如何使钢丝绳自相碾压和磨损,说明钢丝绳直径公差的影响,提出对改进的设想,最后集中到从钢丝绳本身寻找解决方案。

Analysis of special cases in crane wire rope damage, the following points, here to tell you that, good for you. Normal design maintenance crane steel wire rope should be a reasonable service life of wire rope, but may be due to excessive wear and corrosion and premature failure. Proper lubrication of the rope can solve this problem. The rope may also be due to mechanical or structural damage and scrapped prematurely, at this time can only improve the crane and the structure of wire rope and used to work. This article first elaborates the mechanism of wire rope bending fatigue, then analysis of spiral multi-layer winding drum so that the wire rope is how rolling and wear, illustrates the influence of wire rope diameter tolerance, put forward to the improvement, finally to find the solution from the rope itself.

作者认为钢丝绳在缠绕过程中钢丝绳之间互相磨碾产生刻痕,导致钢丝绳过早损坏。钢丝绳外面的绳股越紧密,相互间产生刻痕越少。因此必须把现有6边或8 边形断面的钢丝绳做成圆形断面才能解决问题。经锻造成圆断面的钢丝绳在弯曲机和多层试验台试验显示,寿命可提高2倍。

Author think that the steel wire rope in winding rope mutual grinding produced Nick, lead to premature failure of wire rope. Strand wire rope outside more closely, mutual notch less. So we must put the wire rope has 6 edges or 8 edges cross section made of circular cross section in order to solve the problem. The forged display wire rope round section in bending machine and a multilayer test, the service life can be 2 times.
