Abstract
The invention belongs to the field of flanges and discloses a composite flange which comprises a flange body. The circular plane of the flange body is provided with bolt holes, the flange body is formed by means of glass fiber weaving and RTM (resin transfer molding), the flange is arranged on a transmission shaft, and an adhesive layer which is an adhesive heating and curing layer is arranged at the joint of the flange with the transmission shaft. The composite flange is material-saving in processing and manufacturing, lightweight, resistant to acid, base and corrosion and high in specific stiffness.
Description
Technical field
The present invention relates to the flange field, relate in particular to a kind of flange made of composite material.
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 a large amount of material of loss 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 affects security of operation.
Summary of the invention
The object of the present invention is to provide a kind of processing and fabricating economical with materials, lightweight, acid resistant alkali, corrosion-resistant, the high flange made of composite material of specific stiffness.
Complete skill scheme of the present invention is, a kind of flange made of composite material comprises a flange body, is provided with bolt hole on the disk of described flange body, and described flange body is with fiberglass braided, RTM injecting glue moulding.
Optionally, described flange is arranged on the transmission shaft, and described flange and transmission shaft joint are provided with bonding coat, and described bonding coat is adhesive heating cure layer.
Therefore the present invention has following beneficial effect:
Flange made of composite material of the present invention 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 moulds 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, lightweight, 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 a further understanding of the present invention, consists of the application's a part, does not consist of to improper restriction of the present invention, in the accompanying drawings:
Fig. 1 is structural representation of the present invention.
Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Embodiment 1:
A kind of flange made of composite material of the present invention comprises a flange body 1, is provided with bolt hole 2 on the disk of flange body, 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 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 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 larger difference, without the braiding composite material in fiber be parallel, not overlapping mutually, and at first fiber tuft is made into required structure shape formation preform constructions spare through the composite material of braiding through textile technology, it is space distribution at macrostructure, a fully integral body, it be one continuously, complete network of fibers directly forms required structure with preform constructions spare as strengthening skeleton to carry out impregnation curing.
From the mechanics angle, because the composite material of process braiding and an important difference of common composite material are 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 is widely used on the goods of composite material in Aeronautics and Astronautics field at present, and it is compared with common composite material has unique advantage.
The transmission shaft axis body is made of carbon fiber composite among the present invention, its structure is 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 namely reduced raw material have reduced again machining man-hour.This axis body comprises the attachment hole at axle two ends, and internal diameter and the flange of axle match, and axis body can be linked to each other with flange.
Carbon fiber driving shaft and metal flange machine respectively, metal flange and transmission shaft attachment portion surface finish are processed, increase its surperficial roughness, increase frictional force, then coat glass fibre on its surface, and heating cure, after curing is finished flange is applied epoxy resin at glass fibre and transmission shaft internal surface place, flange is clamp-oned in the transmission shaft heating cure.After finishing, curing uses again screw bolt reinforcing, the join strength of reinforcing flange and axle.
Therefore, flange of the present invention adopts glass fibre, long service life, can be at-50 degree under the environment of 120 degree, under the nominal moment of torsion with carbon fiber driving shaft safe handling 20 years, and quality light, make easy construction, cost of transportation reduces, reduce engineering cost, good corrosion resistance can be acidproof, alkaline-resisting, salt tolerant, can use safely in wet environment; Glass fibre adopts knitting skill, compares with common composite material, and strength increase has increased the intensity of flange made of composite material; Specific stiffness is strong, and the specific stiffness of glass fiber compound material is 5 times of Steel material; Flange made of composite material bonds with directly using adhesive being connected of transmission shaft, just can reach required intensity, has simplified Placement.
More than technological scheme that the embodiment of the invention is provided be described in detail, used specific case herein principle and the mode of execution of the embodiment of the invention are set forth, above embodiment's explanation is only applicable to help to understand the principle of the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, all will change on embodiment and application area, in sum, this description should not be construed as limitation of the present invention.
Claims (2)
