Experimental Study on Effect of Pulley Diameter and Lubricant Grease on Multi-Layer Winding Wire Rope’s Fatigue Endurance

Article Preview

Abstract:

Comparison test method is used to study the effect of pulley diameter and lubricant grease on multi-layer winding wire rope’s fatigue endurance. The investigation indicates that the fatigue failure behavior is closely related to spatial location where the wire rope is in drum; the occurrence and development of broken wires follows regularly. The fatigue endurance of multi-layer winding wire rope is little influenced by lubricant grease, which is greatly affected by the diameter ratio of pulley to rope in multi-layer winding. The results have important reference value for the reliability design of multi-layer winding wire rope.
