Document Type and Number:
WIPO Patent Application WO/2017/166417
Kind Code:
A1
Abstract:
A steel wire rope for an air-impermeable rubber belt, comprising a core strand (1) and several outer strands (2), the several outer strands (2) wrapping around the outside of the core strand (1); the core strand (1) is a linear strand; the core strand (1) is either a cross lay strand or a parallel lay strand; the outer strands (2) each consists of an outer strand core yarn (2.1), an outer strand intermediate yarn layer (2.2) and an outer strand outer yarn layer (2.3), which are arranged from inside to outside; the outer strand outer yarn layer (2.3) consists of outer strand outer yarn layer heavy wires (2.3.1) and outer strand outer yarn layer small-gauge wires (2.3.2), the outer strand outer yarn layer heavy wires (2.3.1) and the outer strand outer yarn layer small-gauge wires (2.3.2) being arranged alternately so as to wrap around the outer side of the outer strand intermediate yarn layer (2.2); and the outer strand outer yarn layer heavy wires (2.3.1) and/or each steel wire of the outer strand intermediate yarn layer (2.2) are bent steel wires having a wavy shape in a plane. The steel wire rope has the advantage of achieving sufficient combination of the rubber belt steel wire rope and rubber, thereby guaranteeing the air impermeableness of the rubber belt.
