Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the drawings.

[0046] Such as Figure 3 to Figure 7 As shown, the present invention is mainly directed to, but not limited to, glass fiber reinforced plastic drive shafts applied to wind power couplings. The bonded glass fiber reinforced plastic drive shaft with profile matching includes a metal flange and a glass fiber reinforced plastic intermediate tube that are bonded together. The metal flange and the glass fiber reinforced plastic intermediate tube have bonding and mating surfaces, and the metal flange and The glass fiber reinforced plastic intermediate pipe has a hexagonal and arc transition mating surface, and the bonding and mating surface of the metal flange and the glass fiber reinforced plastic intermediate pipe is a hexagonal and arc transition bonding structure.

[0047] The end of the bonding structure adopts a linear matching form. The bonding and mating surfaces of the gla...

Abstract

The invention discloses a profile-matched bonding glass fiber reinforced plastic transmission shaft and its production technology. The profile-matched bonding glass fiber reinforced plastic transmission shaft comprises a metal flange and a glass fiber reinforced plastic intermedium tube, which are adhered together. The metal flange and the glass fiber reinforced plastic intermedium tube have a bonding matching surface. The metal flange and the glass fiber reinforced plastic intermedium tube both have a polygonoun and arc transition matching profile. The bonding matching surface of the metal flange and the glass fiber reinforced plastic intermedium tube is a polygonoun and arc transition bonding structure. Through the profile-matched bonding surface, torsional rigidity for self-locking between the matched profile will be greatly increased; bonding strength reliability is greatly raised; and by the adoption of the conical surface matched bonding surface, during the bonding process, matching between the metal flange and the glass fiber reinforced plastic intermedium tube has a self-centering effect, bonding operation difficulty can be reduced, and bonding manufacturability is raised.

Description

Technical field [0001] The invention relates to the field of transmission shafts, in particular to a bonded glass fiber reinforced plastic transmission shaft with matching profile and its production process. Background technique [0002] The FRP drive shaft is mainly used to transmit torsional loads. It is a drive shaft made of FRP; the coupling is connected to the rotating shaft to transmit torsion, realize compensation, and reduce vibration; the bonded FRP drive shaft is made of metal and FRP Bonded glass fiber reinforced plastic drive shaft; glass fiber reinforced plastic drive shaft has many advantages such as light weight, high strength, low price, and can be designed according to force conditions. It is widely used in many fields such as automobiles, construction machinery, ships, and wind power generation. [0003] As an industrial transmission part, couplings have diverse structures, similar functions, and are widely used. Wind power couplings, as a kind of coupling produc...
