What Is Mechanical Wear of Wire Rope and How To Prevent it ?

1.The mechanical wear of wire rope is caused by the running of machine material. In the using process, the outer surface get in touch with the surface of the wheel groove, the drum, etc., causing wear, and the wire diameter will be thinned after the wear, and the outer steel surface of the wire is worn and smoothed. Wire surface wear contains single-sided wear and overall wear.

2.The bending fatigue fracture of the steel rope is caused by rope passing through the wheel groove and retracting of rope in the drum.

The wire rope first forms an initial crack due to various slips, and then the crack tip repeatedly deforms under the action of shear stress, causing the crack to expand and fracture.

3.Prevention and improvement measures:

Firstly, we need to increase the number of the outer wires of the wire rope and reduce the diameter of the outer wire. Secondly, reduce the wire line tension, increase the wheel groove and the drum diameter to increase the durability of the wire rope. Thirdly, lubricate the wire rope, and also apply grease, reduce the friction between the steel wire rope and the equipment to improve the fatigue resistance of the wire rope.
