Abstract
The utility model belongs to the field of a flange, and discloses a flange made of composite material, comprising a flange body; a round plane of the flange body is provided with a bolt hole; the flange body is molded by weaving through glass fiber and injecting glue through resin transfer molding (RTM); the flange is arranged on a transmission shaft; a bonding layer is arranged at the connecting part between the flange and the transmission shaft; and the bonding layer is heated and cured by an adhesive. The utility model aims at providing the flange made of the composite material, which is material-saving in processing and manufacturing, light in weight, acid-base-resistant, corrosion-resistant and high in specific stiffness.
Description
Technical field
The utility model relates to the flange field, relates in particular to a kind of composite material flange.
Background technique
The transmission of power of motor need be used transmission shaft in the large cooling column, and flange is the effective means that connects motor and transmission shaft.Commonly used in the existing technology is metal flange, and it is to form through machined into forging, because the size of forging necessarily, is processed into loss wide variety of materials in the flange process of different size, causes the waste of material, and machining period is long, has increased cost of production.And its quality of the flange of metallic material is heavy, has increased the weight of the weight of composite material transmission shaft, has reduced the advantage of composite material transmission shaft.And be confined to the character of metallic material, metal flange is not corrosion-resistant, resistance to acids and bases not, is prone to accidents, and influences security of operation.
Summary of the invention
The purpose of the utility model is to provide a kind of processing and fabricating economical with materials, in light weight, acid resistant alkali, corrosion-resistant, the high composite material flange of specific stiffness.
The complete skill scheme of the utility model is, a kind of composite material flange comprises a flange body, and the disk of said flange body is provided with bolt hole, and said flange body is with fiberglass braided, RTM injecting glue moulding.
Optional, said flange is arranged on the transmission shaft, and said flange and transmission shaft joint are provided with bonding coat, and said bonding coat is an adhesive heating cure layer.
Therefore the utility model has following beneficial effect:
The utility model composite material flange adopts braiding, the moulding of RTM injecting glue, because the interaction of structural member fiber tuft kink place of knitting forming exists adhesion and frictional force, the sectional shape of fiber tuft is changed, and fabric is enhanced; Can when die press technology for forming, select different dies for use according to required size during making, directly be processed into required size, avoid the waste of material, reduce process time.And the raw material of this flange are glass fibre; In light weight, the acid resistant alkali of this flange, corrosion-resistant, specific stiffness advantages of higher; Unite the advantage that use can better be brought into play composite material transmission shaft with composite material transmission shaft, can be used in longspan, the high-revolving Environmental Conditions with the composite material transmission shaft coupling.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.
Embodiment 1:
A kind of composite material flange of the utility model comprises a flange body 1, and the disk of flange body is provided with bolt hole 2, and flange body 1 usefulness is fiberglass braided, the moulding of RTM injecting glue; Flange is arranged on the transmission shaft, and the joint of flange and transmission shaft is provided with bonding coat, and bonding coat is an adhesive heating cure layer.
Braiding, the moulding of RTM injecting glue are adopted in the moulding of flange body in the present embodiment.With reference to the The Knitting Principle in the textile manufacturing machine; Consider the characteristic of glass fibre, knitting machine is transformed into the structure that is fit to braided glass fibre, the composite material of knitting forming and common composite material have bigger difference; Without the braiding composite material in fiber be parallel, do not overlap mutually; And the composite material of process braiding at first is made into required structure shape formation preform constructions spare with fiber tuft through textile technology, and it is space distribution on macrostructure, is an integral body fully; It is continuous, a complete network of fibers, lets preform constructions spare is directly formed required structure as strengthening skeleton to carry out impregnation curing.
See from the mechanics angle; Because through the composite material of braiding and an important difference of common composite material is that fiber forms an integral body through twisting together each other in the preform constructions spare that weaves; Because the interaction of structural member fiber tuft kink place of knitting forming; Exist adhesion and frictional force, the sectional shape of fiber tuft is changed, fabric is enhanced.Therefore this kind knitting skill extensively applies on the goods of composite material in Aeronautics and Astronautics field at present, and it is compared with common composite material has special advantages.
The transmission shaft axis body is made up of carbon fiber composite in the utility model; Its structure is a tubulose, has reduced the use of material, and its preparation process is can be according to the length of axis body; The length of cutting carbon fibre cloth, the waste that has promptly reduced raw material have reduced machining man-hour again.This axis body comprises the attachment hole at a two ends, and the internal diameter and the flange of axle match, and axis body can be linked to each other with flange.
Graphite fiber transmission shaft and metal flange machine respectively, and metal flange and transmission shaft attachment portion surface finish are handled, and increase its surperficial roughness; Increase frictional force; Coat glass fibre on its surface then, and heating cure, after curing is accomplished flange is applied epoxy resin at glass fibre and transmission shaft internal surface place; Flange is clamp-oned in the transmission shaft heating cure.Use screw bolt reinforcing again after solidifying completion, the join strength of reinforcing flange and axle.
Therefore the utility model flange adopts glass fibre, long service life; Can spend under the environment of 120 degree-50, under the nominal moment of torsion, use safely 20 years, and light weight, make easy construction with the graphite fiber transmission shaft; Cost of transportation reduces; Reduce engineering cost, good anti-corrosion can be acidproof, alkaline-resisting, salt tolerant, can in wet environment, use safely; Glass fibre adopts knitting skill, compares with common composite material, and intensity increases, and has increased the intensity of composite material flange; Specific stiffness is strong, and the specific stiffness of glass fiber compound material is 5 times of steel; The composite material flange bonds with directly using adhesive being connected of transmission shaft, just can reach required intensity, has simplified Placement.
More than technological scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
