Abstract
The utility model relates to a polyurethane automobile synchronous belt with basalt fiber rope cores. The automobile synchronous belt comprises a belt colloid of which the section is rectangular; basalt fiber ropes are arranged in the belt colloid and consist of basalt fiber rope cores and cladding layers; the basalt fiber rope cores are core ropes which are formed by stranding and twisting basalt fiber twistless roving; and the cladding layers are polyurethane cladding layers. The basalt fiber ropes are arranged in the belt colloid of a transmission belt, so that the transmission belt is high in transmission intensity, light in weight and soft, and is low in elongation and high in heat resistance compared with those of a fabric canvas flat transmission belt, and is low in price and high in cost performance compared with those of high technical fiber; and the basalt fiber rope cores are coated by polyurethane, so that tension strength loss of the basalt fiber rope cores, which is caused by easiness in breakage caused by fiber weakness in the manufacturing process of the belt can be effectively reduced, and the bonding intensity of the rope cores and the polyurethane belt colloid is increased.
Description
Technical field
The utility model relates to the driving belt that a kind of equipment is used, and particularly relates to a kind of polyurethane automobile that has the basalt fibre wire rope core and is with synchronously.
Background technique
Its inside of the automobile synchronous belt of existing technology is with the tension element of wire rope as driving belt; The fracture great majority of driving belt are owing to Steel cord corrosion fracture causes; And big with wire rope as the tension element weight of driving belt, consume the more powerful, energy-conservation inadequately of traction electric machine; Also have at present and use aramid fibre, superhigh molecular weight polyethylene fibers wire rope core to produce driving belt, 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 belt, provides a kind of polyurethane automobile that has the basalt fibre wire rope core to be with synchronously.
For achieving the above object, the utility model adopts following technological scheme:
A kind of polyurethane automobile that has the basalt fibre wire rope core is with synchronously, comprising: core rope, the band back of the body, band tooth, and described core rope is basalt fibre core rope, and described basalt fibre core rope is provided with the polyurethane clad, and basalt fibre core rope is located at the inside of the band back of the body.
The core rope that described basalt fibre core rope is basalt fibre roving Split Down twisting.
The described band back of the body and the used material of band tooth are the thermoplastic polyurethane elastomer, and described thermoplastic polyurethane elastomer is polyester type and polyether-type.
The beneficial effect of the utility model: owing to be provided with basalt fibre core rope in the band of the band back of the body synchronously; Basalt fibre core rope is fibrous by basalt (CBF), and the tensile strength of basalt (CBF) fiber is 4450～4800MPa, and is all higher than large-tow carbon fiber, aramid fibre, Steel Fibre; The core rope that utilizes basalt fibre roving twisting Split Down to process has high tenacity, high-modulus, good heat resistance, characteristics that elongation percentage is low; Replace Steel cord to produce poly Vbelt as tension element, its tensile strength is higher, elongation percentage is lower, weight lighter (proportion be merely steel 1/3); Compare with the Steel cord poly Vbelt as the polyurethane synchronous belt 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 synchronous band, uses the synchronous band of high technology fiber (aramid fibre, 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 fibrous is crisp and to cause the loss of tensile strength, increased the bonding strength of wire rope core and polyurethane core glue simultaneously.
Description of drawings
Fig. 1 is one of them embodiment's of the utility model a schematic perspective view.
Embodiment
Can find out with reference to Fig. 1; A kind of polyurethane automobile that has the basalt fibre wire rope core is with synchronously, comprising: core rope 3, the band back of the body 1, band tooth 2, and described core rope 3 is basalt fibre core rope; Described basalt fibre core rope is provided with the polyurethane clad, and basalt fibre core rope is located at the inside of the band back of the body 1.The core rope that described basalt fibre core rope 3 is basalt fibre roving Split Down twisting.The described band back of the body and the used material of band tooth are the thermoplastic polyurethane elastomer, and described thermoplastic polyurethane elastomer is polyester type and polyether-type.
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 belt 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 bonding strength of wire rope core and polyurethane belt body glue.
