What is the classification of the wire rope according to the contact state
2025-01-06
Wire rope is a flexible rope twisted with multiple or multiple strands of thin steel wire, the wire rope is twisted into strands by multiple layers of steel wire, and then centered on the rope core, by a certain number of strands twisted into a spiral rope. In material handling machinery, used for lifting, pulling, tensioning and carrying. The strength of the wire rope is high, the weight is light, the work is stable, the whole wire rope is not easy to break suddenly, and the work is reliable.
We know that the rope can be divided into single rope, double rope and three rope according to the level of twisting. The following mainly analyzes the main classification of steel wire rope according to the contact state. Experts pointed out that the wire rope can be divided into point contact, line contact and surface contact according to the contact state between each layer of steel wire in the strand. First, let's talk about the wire rope in contact. The diameters of the wires in the point contact strand are the same. In order to uniform the force of the steel wire, the spiral Angle after each layer of steel wire twisting is roughly equal, but the twisting distance is different, so the inner and outer layers of steel wire cross each other and show a point contact state. Second, the wire contacts the wire rope. The twist distance of each layer of steel wire in the wire rope strand is equal, and the inner and outer layers of steel wire contact each other on a helix, which is in line contact state. The performance of wire contact wire rope is much improved than that of point contact, so it is widely used. |
