Abstract
The utility model relates to a V belt with a contact surface made of a polyurethane-polyether elastomer, which comprises a canvas connecting layer and a V-shaped elastomer belt which are cast. The outer part of the elastomer is provided with a canvas wrapper layer, the elastomer and the canvas wrapper layer connected together are cast, an anti-pulling wire is arranged in the elastomer, and the anti-pulling wire and the elastomer connected together are formed by casting. The product can be formed by one-step casting and has the advantages of simple manufacturing process, compact structure, time saving, labor saving, material saving, high anti-pulling strength, high oil resistance, high heat resistance, high abrasion resistance and high oxidation resistance. The product can obviously raise service performance and reduce the maintenance load of stopping drive and the labor intensity of maintainers, therefore, raise the utilization efficiency. Through testing, the stretching strength KN of the product is larger than or equal to 9.7, the elongation at reference load is smaller than or equal to 6, and the dial-off strength KN is larger than or equal to 1.9. The service life of the product is much longer than that of an original product, and multiple items of technical indexes are higher than national V belt standard indexes.
Description
The utility model relates to a kind of belt drive unit with polyurethane polyethers type elastomer outsourcing cloth V band, is specially adapted to oil field and industrial vee belt.
The elastomer of present existing like product does not have the canvas covering outward; tensile cord is easily peeled off and is torn in it; thereby the softening transform that is heated easy to wear; tensile strength is low; reduced usability; increased shutdown maintenance workload and maintenance man's labor intensity and operating efficiency, working life is short, and therefore existing V band is badly in need of improving.
The purpose of this utility model provides the polyurethane polyethers type elastomer outsourcing cloth V band that a kind of belt drive unit is used, its compact structure, and manufacturing process is simple, saving of labor, material-saving, significantly improve working life and usability, improve Utilization ratio and working efficiency, reduce maintenance man's labor intensity.
For achieving the above object, the technical solution of the utility model is: a kind of polyurethane polyethers type elastomer outsourcing cloth V band, comprise canvas binder course and V-type elastomeric band moulding by casting, elastomer is provided with the canvas bag layer of cloth outward, elastomer and the conjuncted cast of canvas bag layer of cloth, tensile cord is set, the conjuncted moulding by casting of tensile cord and elastomer in the elastomer.
Because the utility model adopts above-mentioned improvement, EU one-time cast-forming with single variety, technology is simple, and compact structure saves time, the saving of labor, material-saving, the thermal softening that is subjected to that has overcome effectively that prior art exists is upheld low shortcoming of distortion, working life, its tensile strength height, and oil resistant, heat-resisting, wear-resisting, resistance to oxidation can obviously improve its usability.Reduce shutdown maintenance workload and maintenance man's labor intensity; thereby improved the utilization ratio of equipment; its stretching bullet degree KN 〉=9.7 after tested; reference load elongation percentage≤6; dial and take off intensity KN 〉=1.9; be higher than existing product its working life far away, multinomial technical order is higher than national V band standard index.
Fig. 1 is a structural profile schematic representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
A kind of polyurethane polyethers type elastomer outsourcing cloth V band, comprise canvas binder course 1 and V-type elastomeric band 2 moulding by casting, the elastomer 2 outer canvas bag layer of cloths 3 that are provided with, elastomer 2 and the 3 conjuncted cast of canvas bag layer of cloth, tensile cord 4 is set, tensile cord 4 and elastomer 2 conjuncted moulding by casting in the elastomer 2.
The utility model can be made the product of all size according to the actual demand of the transmission device of equipment, its structure is a V-type elastic strip and with its canvas binder course two-part that join together, V-type elastomeric band and canvas outsourcing cloth, tensile cord are one-time cast-forming, adopt specialized mould once-cast technology, easy and simple to handle, the saving of labor, material-saving.Outsourcing canvas layer and tensile cord can significantly improve the pull resistance of this product, make to be higher than like product its working life far away.
