Abstract

Disclosed is a steel wire rope for conveyor belts. The steel wire rope includes a central steel wire, a steel wire layer externally wound on the central steel wire, and a plurality of external steel wire strands. Each external steel wire strand includes a core steel wire and N external steel wires. The central steel wire, the steel wire layer externally wound on the central steel wire, and the plurality of external steel wire strands are wound into a steel wire rope for conveyor belts in one step. The steel wire layer is externally wound on the outer side of the central steel wire, the external steel wire strands are wound to wrap the outer side of the steel wire layer, and the external steel wire strands are in line contact with the steel wire layer.

Abstract

A steel wire rope for a conveyor belt comprises a central steel wire (3), a steel wire layer (4) wound outside of the central steel wire, and a plurality of external steel wire strands (5) with each comprising a core steel wire (5.1) and N external steel wires (5.2); the central steel wire, the steel wire layer wound outside of the central steel wire and the plurality of external steel wire strands are twisted in one step to form the steel rope for the conveyor belt, the steel wire layer is wound at the outer side of the central steel wire, the outer side of the steel wire layer is wrapped up by the external steel wire strands, and the external steel wire strands are in line contact with the steel wire layer; the steel wire layer wound outside of the central steel wire is composed of M steel wires or M steel wires and M' externally-wound steel wire strands, the ratio of M' to M is 0.25:1 to 1:1 when the steel wire layer is composed of the M steel wires and the M' externally-wound steel wire strands, and each externally-wound steel wire strand has 2 to 12 steel wires.
