Abstract
The utility model relates to a polyurethane double-sided transmission belt with a basalt fiber core rope, which comprises a polyurethane double-sided transmission belt body and a tensile body, wherein the tensile body is the basalt fiber core rope; the core rope is arranged inside the polyurethane double-sided transmission belt body; and a polyurethane coating layer is arranged on the core rope. The polyurethane double-sided transmission belt has the beneficial effects that as the basalt fiber rope is arranged in the polyurethane double-sided transmission belt body, the transmission belt has higher strength, softer belt body and light weight, has lower elongation rate and better heat resistance compared with a fiber fabric canvas flat transmission belt and has lower cost and better cost performance compared with a high-technology fiber belt; and through polyurethane coating treatment, the loss of tensile strength caused by easy breaking of the basalt fiber core rope due to brittle fiberation in the belt manufacturing process can be effectively reduced, and meanwhile, the bonding strength between the rope core and the double-sided transmission belt body is increased.
Description
Technical field
The utility model relates to the driving band that a kind of equipment is used, and particularly relates to a kind of two-sided driving band of polyurethane that has basalt fibre core rope.
Background technology
Its inside of two-sided driving band of prior art is with the tension element of steel rope as driving band; The fracture great majority of driving band are owing to Steel cord corrosion fracture causes; And big with steel rope as the tension element weight of driving band, consume the more powerful, energy-conservation inadequately of traction electric machine; Also have at present and use aramid fiber, superhigh molecular weight polyethylene fibers wire rope core to produce driving band, but cost is high as tension element.
Summary of the invention
The purpose of the utility model is exactly the defective that overcomes present driving band, and a kind of two-sided driving band of polyurethane that has basalt fibre core rope is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of two-sided driving band of polyurethane that has basalt fibre core rope; Comprise: the two-sided transmission belt body of polyurethane, tension element; Described tension element is located at the inside of the two-sided transmission belt body of polyurethane for basalt fibre core rope, core rope, and described core rope is provided with the polyurethane clad.
The two-sided transmission belt body of described polyurethane comprises two-sided synchronous belt body or the two-sided belt body of synchronous many wedges.
Described two-sided its profile of tooth of synchronous belt body can be stepped tooth, circle-arc tooth or herringbone tooth, and the described two-sided belt body of synchronous many wedges profile of tooth wherein can be stepped tooth, circle-arc tooth or herringbone tooth.
The core rope that described basalt fibre core rope is basalt fibre roving Split Down twisting.
The used material of the two-sided transmission belt body of described polyurethane is the thermoplastic polyurethane elastic body, and described thermoplastic polyurethane elastic body is polyester type and polyether-type.
The beneficial effect of the utility model: owing to be provided with basalt fibre core rope in the two-sided driving band; Basalt fibre core rope is fibrous by basalt (CBF), and the pulling strengrth of basalt (CBF) fiber is 4450～4800MPa, and is all higher than large-tow carbon fiber, aramid fiber, steel fiber; The core rope that utilizes basalt fibre roving twisting Split Down to process has high strength, high-modulus, good heat resistance, characteristics that percentage elongation is low; Replace Steel cord to produce two-sided driving band as tension element, its pulling strengrth is higher, percentage elongation is lower, weight lighter (proportion be merely steel 1/3); Compare with the two-sided driving band of Steel cord as the two-sided driving band of the polyurethane of tension element manufacturing with the basalt fibre wire rope core; Its intensity is higher, belt body is more soft, can significantly reduce the weight of two-sided driving band, uses the two-sided driving band of hightech fiber (aramid fiber, superhigh molecular weight polyethylene fibers) wire rope core production to compare with other; Its price is lower, and cost performance is better; Because the basalt fibre wire rope core is to be added by the Split Down of basalt fibre roving to be twisted into; The basalt fibre wire rope core coats through polyurethane and handles; Can effectively reduce the basalt fibre wire rope core in system band process; Fracture easily because of fiberation is crisp and to cause the loss of pulling strengrth, increased the bond strength of wire rope core and polyurethane core glue simultaneously.

The specific embodiment
Can find out that with reference to Fig. 1 the utility model comprises: the two-sided transmission belt body of polyurethane 2,3, tension element 1, described tension element 1 are basalt fibre core rope; The core rope is located at the inside of the two-sided transmission belt body of polyurethane; Described core rope is provided with the polyurethane clad, the core rope that described basalt fibre core rope is basalt fibre roving Split Down twisting, and the two-sided transmission belt body of the polyurethane of present embodiment is two-sided synchronous belt body; The two sides profile of tooth is identical, and two-sided its profile of tooth of synchronous belt body is a circle-arc tooth.
Can find out with reference to Fig. 2; The utility model comprises: the two-sided transmission belt body of polyurethane 2,3, tension element 1, described tension element 1 are basalt fibre core rope, and the core rope is located at the inside of the two-sided transmission belt body of polyurethane; Described core rope is provided with the polyurethane clad; The core rope that described basalt fibre core rope is basalt fibre roving Split Down twisting, the two-sided transmission belt body of the polyurethane of present embodiment is the two-sided belt body of synchronous many wedges, just one side is a synchronous cog belt; Another side is a triangular belt, and the profile of tooth of cog belt is trapezoidal.The two-sided driving band of the utility model comprises the two-sided driving band of annular two-sided driving band and ports having (two ports being arranged, not ringwise).
The polyurethane clad of the utility model is that the basalt fibre heart yearn coats the very thin melt of one deck (coating thickness is about 0.08mm) through extruder around heart yearn; Process through the tank slow cooling again; Use has the basalt fibre core rope of clad, and not only driving band intensity is high, and because the clad with basalt fibre wire rope core tension element of band colloid is a same material; Both can well combine, thereby have increased the bond strength of wire rope core and polyurethane belt body glue.
