Abstract
The utility model relates to a polyurethane ribbed belt with a basalt fiber rope core. The polyurethane ribbed belt comprises top glue, core ropes, core glue and wedge glue, wherein the basalt fiber core ropes are arranged in the core glue and consist of basalt fiber core yarns and cladding layers; the basalt fiber core yarns are formed by stranding and twisting basalt fiber twistless roving; and the cladding layers are polyurethane cladding layers. The basalt fiber core ropes are arranged in a belt colloid of the ribbed belt, so a transmission belt is high in strength, and a belt body is soft and light in weight; compared with a fiber fabric canvas flat transmission belt, the polyurethane ribbed belt is low in elongation and high in heat resistance; compared with high-technology fibers, the polyurethane ribbed belt is low in cost and high in cost performance; and the basalt fiber rope core is wrapped by polyurethane, so the loss of tensile strength caused by high possibility of breaking due to fragile fiberation in the process of manufacturing the basalt fiber rope core can be reduced effectively, and the bonding strength of the rope core and the polyurethane belt body glue is enhanced.
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 poly Vbelt that has the basalt fibre wire rope core.
Background technique
The poly Vbelt of existing technology generally uses as driving belt; Its inside 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, and a kind of polyurethane poly Vbelt that has the basalt fibre wire rope core is provided.
For achieving the above object, the utility model adopts following technological scheme:
A kind of polyurethane poly Vbelt that has the basalt fibre wire rope core comprises: top glue, core rope, core glue, wedge glue are provided with basalt fibre core rope in the described core glue; Described basalt fibre core rope is made up of basalt fibre heart yearn and clad, and described basalt fibre heart yearn is the heart yearn of basalt fibre roving Split Down twisting, and described clad is the polyurethane clad.
Described top glue, core glue and wedge glue 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 core glue of driving belt; 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 poly Vbelt 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 poly Vbelt, uses the poly Vbelt 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 cross section stereo schematic representation.
Embodiment
Can find out that with reference to Fig. 1 the utility model comprises: top glue 1, core rope 2, core glue 3, wedge glue 4 are provided with basalt fibre core rope 2 in the described core glue 3; Described basalt fibre core rope 2 is made up of basalt fibre heart yearn and clad, and described basalt fibre heart yearn is the heart yearn that the Split Down of basalt fibre roving is twisted, and described clad is the polyurethane clad.Described top glue, core glue and wedge glue 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.The poly Vbelt of the utility model comprises annular poly Vbelt and ports having (two ports are arranged, do not circularize) poly Vbelt.
Claims (2)
1. polyurethane poly Vbelt that has the basalt fibre wire rope core, comprising: top glue, core rope, core glue, wedge glue is characterized in that: be provided with basalt fibre core rope in the described core glue; Described basalt fibre core rope is made up of basalt fibre heart yearn and clad, and described basalt fibre heart yearn is the heart yearn of basalt fibre roving Split Down twisting, and described clad is the polyurethane clad.
