起重机配件中重要者之一就是钢丝绳，它决定着起重机吊运物品的安全度，好的钢丝绳安全度高，反之就安全度就低了，下面我们就说明一下钢丝绳： 钢丝用优质碳钢制成，经多次冷拔和热处理后可达到很高的强度。潮湿或露天环境等工作场所可采用镀锌钢丝拧成的钢丝绳，以增强防锈性能。钢丝绳在各工业国家中都是标准产品，可按用途需要选择其直径、绳股数、每股钢丝数、抗拉强度和足够的安全系数，它的规格型号可在有关手册中查得。钢丝绳除外层钢丝的磨损外，主要因绕过滑轮和卷筒时反复弯曲引起起重机配件疲劳而逐渐折断，因此滑轮或卷筒与钢丝绳直径的比值是决定钢丝绳寿命的重要因素。比值大，钢丝弯曲应力小，寿命长，但机构庞大。必须根据使用场合确定适宜的比值。钢丝绳表面层的磨损、腐蚀程度或每个拧距内断丝数超过规定值时应予报废。钢丝绳主要用在吊运，拉运等需要高强度线绳的运输中。 在起重机的减速器中或者是在车轮的轴承箱中，要是径向的轴承和径向的推轴承的内座圈方向瓯都是固定位置的轴上的，所以在这些轴字转动的时候，设备的外座圈上的装置都是在固定的轴承座的镗孔中，其是可以装置上固定的轴承座的轴承套里面的，还可以根据轴承的类型和方式来进行安装的方式，这样都是根据使用的需求来决定的。
Lifting accessories in the wire rope is one of important people, it decides the degree of safety of crane items, good wire rope safety degree is high, whereas safety is low, let's explain: wire rope steel wire made from high quality carbon steel, after cold drawing and heat treatment can achieve very high intensity. Damp or open environment such as workplace can use galvanized steel wire rope to, to enhance anti-corrosion properties. Wire rope are standard products among industrial countries, according to use need to select the rope diameter, number of shares, the number of wire per share, tensile strength and enough safety coefficients and its specifications can Chad in the relevant manual. Except for the steel wire layer of wire rope wear, mainly caused by repeated bending with bypass pulley and drum crane parts gradually broken, and fatigue so pulley or drum and wire rope diameter ratio is an important factor decided to wire rope life. Ratio is large, the wire bending stress is small, long life, but the bloated. Must be used according to the situation to determine the appropriate ratio. Degree of surface layer of wire rope wear, corrosion or broken wires in each screw pitch over specified value shall be scrapped. Wire is mainly used in lifting, just need high strength cord in transport. In hoist reducer or is in the wheel bearing housing, if the radial bearing and radial bearing inner race ou are fixed position of the shaft in the direction, so words in these axis rotation, equipment installation on the outside of the circle is in the fixed and the bore of the bearing, it is can be fixed on the device and the bearing of the bearing cover, can also according to the type of bearing and ways to handle installation way, so that is decided according to using requirements.
