Title:
STEEL WIRE ROPE WITH SIX-STRAND FIBER FILLED CORE AND PROCESS AND SPECIAL EQUIPMENT FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2012/016524
Kind Code:
A8
Abstract:
Disclosed are a steel wire rope having a six-strand fiber filled core and a process and special equipment for manufacturing same. The steel wire rope comprises a steel core (1), and six outer layer strands (2) twisted on the steel core, with each of the outer layer strands (2) being compacted individually, and an oil-containing high molecular polymer cord (3) embedded between the steel core and two adjacent outer layer stands. By means of a compacting process applied to the outer layer strands, the outer surfaces thereof become tidy and smooth, so that the contact areas between the steel wire rope and a pulley, a winding drum, and a supporting roller are increased, the stress concentration is reduced, and the probability of the steel wire rope being scrapped as a result of wires breaking prematurely is reduced; and embedding the oil-containing high molecular polymer cord between the steel core and two adjacent outer layer strands effectively solves the problems of insufficient oil storage in the steel wire rope and rigid contact between the strands and the core, such that the service life of the steel wire rope is increased by more than 80% as compared with the steel wire ropes originally used.
