Generally, galvanized steel wire rope will produce a certain amount of wear, and the wear is also divided into external surface wear and internal surface wear. Then the wear caused by the friction between the surface of the galvanized steel wire rope and the pulley groove and other objects is what we call external surface wear; and the internal surface wear we call is usually the galvanized steel wire rope during use. loss due to fretting friction.
If the internal fretting surface wear of the galvanized steel wire rope during use has formed extremely serious wear and tear on the surface between the wire strands, the galvanized steel wire rope will fail and its life will be shortened, and the steel wire will therefore be damaged. Fatigue even produces fracture, so it also reflects the correlation between the wear damage caused by the fretting of the inner surface of the galvanized steel wire rope and the fatigue fracture caused by the fretting. The joint action between fretting wear and alternating stress will accelerate the generation and fracture of fatigue cracks in galvanized steel wire ropes, because such wear and tear shortens the service life of galvanized steel wire ropes greatly, so fretting wear is the failure of galvanized steel wire ropes. The main reason for the shortening of lifespan.
