CN2191232Y - Three-angle strand wire rope with thread contact - Google Patents

Abstract

The utility model relates to a three-angle strand steel cable with thread contact. The three-angle strand steel cable with thread contact is twisted with six strands. The outer contour of each strand forms a three-angle shape. Each strand of strand core of the steel cable is an arbitrary configuration. Steel wires on three surfaces are respectively formed with a channel. An outer layer is more provided with three steel wires with a supplemental edge angle than an adjacent inner layer constantly. The three-angle strand steel cable with thread contact can improve the service life of the steel cable and can lay the foundation for developing a three-angle strand steel cable with surface contact.

Description

Three-angle strand wire rope with thread contact

The utility model relates to a kind of triangular strand wire rope of line contact, belongs to the metal wire rod secondary product.

Relation of every steel wire and adjacent wires etc. all is to influence the steel wire rope key factor in service life in the section configuration of steel wire rope, the composition of thread and each strand.

Before the utility model was made, steel wire rope commonly used was many based on round-strand rope.The steel wire rope of another kind of form is some contact triangular strand wire rope, each thigh that so-called some contact triangular strand wire rope is exactly a steel wire rope is triangular shape, every layer of steel wire in strand contacts for point with the steel wire of adjacent layer, though the steel wire rope of this structure has correspondingly improved the service life (only for round-strand rope) of steel wire rope.But because the qualification of its version is difficult to further improve its service life.

The utility model just provides a kind of line contact triangular strand wire rope, and each strand of triangular strand wire rope contacted for every layer of steel wire is wire with the adjacent layer steel wire.Thereby can improve the service life of triangular strand wire rope greatly.

Line contact triangular strand wire rope planform accompanying drawings of the present utility model is as follows:

Fig. 1: a kind of line contact triangular strand wire rope sectional drawing.

Line contact triangular strand wire rope of the present utility model is formed by six bursts of twistings, and each thigh is made up of with several layers (2～3 layers) steel wire triangle thigh core respectively and per share outline all becomes triangular shape.So-called line contact triangular strand only refers to the line contact relation between the inside and outside two-layer steel wire.The thigh core of this steel wire rope can be any one structure, and each layer steel wire number beyond strand core is unequal, outerly Duos three steel wires than the internal layer adjacent perseverance, and promptly cover wire is all walked ditch on three faces, and respectively has a steel wire to replenish corner angle on three ribs.The lay pitch of each layer steel wire of the triangular strand wire rope of line contact is unequal, and its ratio changes with the number of each layer steel wire and the size of burst spiral distance.

The triangular strand wire rope of line contact of the present utility model to be applied as example in the mine pulley transmission system, is compared with some contact triangular strand wire rope with the circle thigh of same diameter, can improve 4 times and 1.5 times its service life respectively.In the service life that the triangular strand wire rope of this line contact not only can improve steel wire rope greatly, also the development of the triangular strand wire rope that contacts for face is laid a good foundation.

Claims (2)

1, the triangular strand wire rope of a kind of line contact, it is formed by six bursts of twistings, and per sharely is made up of triangle thigh core and several layers steel wire respectively, and the per share outline that it is characterized in that steel wire rope is triangular shape and the steel wire on three faces is all walked ditch.

2, the triangular strand wire rope of line according to claim 1 contact is characterized in that each layer steel wire number beyond strand core does not wait, and outerly three steel wires that replenish corner angle than the adjacent inner layer perseverance more.
