Abstract
A kind of rubber belt track steel cord, it comprises the outer strands of a center strand and the stranded even twisting on it of the six roots of sensation, and outer strands is in cylindrical space inside spin predeformation, and center strand is twisted with the fingers to contrary with outer strands, and twists with the fingers to identical with steel cord.Every root strand comprises an interior core wire and is stranded in the six roots of sensation cover wire composition on this interior core wire, outer strands seven steel wire filament diameters are identical with center strand outer six roots of sensation steel wire filament diameter, for 0.20-0.30mm, the interior core wire of center strand and cover wire diameter are 1.3-1.4 than D1/D0, and this root steel wire is planar the prefabricated distortion of steel wire diameter 1.25-1.40 times through predeformation wave height.The utility model cord well solves the problem of core wire fracture of wire in crawler belt use procedure of traditional structure central strand, and is convenient to the infiltration of rubber, improves the bonding force of cord and rubber, improves anti-fatigue performance.
Description
Technical field
The utility model relates to steel cord, particularly a kind of rubber belt track steel cord.
Background technology
Rubber belt track is because it is lightweight, intensity is high, the products such as fire-retardant, antiknock, antistatic, high temperature resistant, acid and alkali-resistance can be produced according to customer requirement, while meeting various particular/special requirement, and have running gear noise low, vibrate little, so be particularly suitable for the occasion of high speed rotating, All-terrain can be realized and pass through performance.
Steel cord is one of critical component of rubber belt track, and its performance characteristics determines very greatly the service life of crawler belt to a certain extent.But existing steel cord structure characteristic limits the service life of crawler belt, 7 × 7 traditional series are primarily of center strand and be distributed on its outer six roots of sensation strand integument composition, center strand is made up of an interior core wire and outer uniform six roots of sensation cover wire thereof, outer six roots of sensation strand integument is by an interior core wire and outer uniform six roots of sensation cover wire composition thereof, an outermost layer outer wrapping wire winding prevents loose, the all filament diameters of this structure cord are identical, although close structure is even, but limit the combination of rubber and cord, poor adhesion, and monofilament contact closely, easily rub between steel wire, reduce fatigue behaviour, affect the service life of crawler belt.
In addition, this structure cord only has the interior core wire in core stock strand not have deflection in twisting process, fracture is easy to because loading characteristic is different from other monofilament in Long-Time Service process, thus destroy the rubber layer of crawler belt, and there is no predeformation due to this monofilament, also limit the pliability of cord itself, someone attempts to remove core stock strand inner sandwich layer and solves this problem, but inner sandwich layer is removed, propose very high requirement to cord explained hereafter, six steel wires are very easily extruded into inner sandwich layer wherein piece when mutually twisting.
Summary of the invention
The purpose of this utility model is to provide a kind of rubber belt track steel cord, and it is good that it has bonding force, the features such as antifatigue, as for 7 × 7 Series Steel cords, not destroying the uniform and smooth feature of 7 × 7 traditional serial cords one-tenth ropes, eliminating again outer wrapping wire, raising the efficiency.
For achieving the above object, the technical solution of the utility model is:
A kind of rubber belt track steel cord, is characterized in that, comprise the outer strands of a center strand and the stranded even twisting on it of the six roots of sensation, outer strands is in cylindrical space inside spin predeformation, and center strand is twisted with the fingers to contrary with outer strands, and twists with the fingers to identical with steel cord.
Further, described center strand is identical with the lay pitch of outer strands, and the lay pitch is 0.6 ~ 0.7 times of length of lay for steel cord, and length of lay for steel cord is 18 ~ 20mm.
Again, described center strand and outer strands include an interior core wire and are stranded in the six roots of sensation cover wire composition on this interior core wire; Described outer strands seven steel wire filament diameters are identical with center strand outer six roots of sensation steel wire filament diameter, are 0.20 ~ 0.30mm.
Preferably, the interior core wire of described center strand and cover wire diameter are 1.3 ~ 1.4 times than D1/D0.
Preferably, the interior core wire of described center strand is planar through prefabricated distortion, and predeformation wave height is 1.25 ~ 1.40 times of steel wire diameter.
The utility model compared with prior art tool has the following advantages:
1. structure length of lay for steel cord 18-20mm of the present utility model, more smaller than tradition 7 × 7 serial lay pitch, and six roots of sensation outer strands is in cylindrical space inside spin predeformation, and all non-predeformation of existing traditional outer strands, therefore, the utility model cord is not loose, therefore can remove the outer wrapping wire of tradition 7 × 7 series.
2. the utility model center strand inner core steel wire and center strand cover wire diameter are 1.3-1.4 times than D1/D0, like this, outer six roots of sensation steel wire can not wrap interior core wire completely, and between cover wire, there is certain gap, in addition, center strand diameter is thick, outer strands can not wrap up center strand completely, be convenient to the infiltration of rubber, decrease between strand and friction between the strand steel wire of center, improve anti-fatigue performance.
3. the utility model center strand inner core steel wire planar gives certain predeformation amount before twisting, rubber can well permeate into, greatly can improve bonding force, and there is because there being predeformation good extensibility and certain space, not only can prevent center strand inner core steel wire from stinging out, and 7 × 7 serial center strand inner core steel wires can be solved used the problem that can rupture of a specified duration, improve the service life of rubber belt track greatly.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the utility model steel cord one embodiment.
Fig. 2 is the distortion schematic diagram of the utility model steel cord center strand inner core steel wire.
