Embodiment Construction

[0046] Below in conjunction with the accompanying drawings, the present invention will be further described in detail.

[0047] Such as Figure 3 to Figure 7 As shown, the present invention is mainly aimed at but not limited to the fiberglass transmission shaft applied to the wind power coupling. The bonded FRP transmission shaft with form fit includes a metal flange and a FRP intermediate pipe bonded together, the metal flange and the FRP intermediate pipe have a bonded mating surface, and the metal flange and the FRP intermediate pipe have a bonded mating surface. The FRP intermediate pipes all have a mating surface of a hexagon plus an arc transition, and the bonded mating surface of the metal flange and the FRP intermediate pipe is a bonding structure of a hexagon plus an arc transition.

[0048] The end of the bonding structure adopts a straight-line fitting form. The bonded mating surface of the FRP intermediate pipe and the metal flange adopts a surface fitting meth...

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

[0001] technical field [0002] The invention relates to the field of drive shafts, in particular to a form-fit bonded fiberglass drive shaft and a production process thereof. Background technique [0003] The FRP transmission shaft is mainly used to transmit torsional loads. It is a transmission shaft made of FRP; the coupling connects the rotating shaft to transmit torsion, realize compensation, and reduce vibration; the bonded FRP transmission shaft is made of metal and FRP. Bonded FRP transmission shaft; FRP transmission shaft has many advantages such as light weight, high strength, low price, and can design the structure according to the force situation, and is widely used in many fields such as automobiles, construction machinery, ships, and wind power generation. [0004] As an industrial transmission part, the coupling has various structures, similar functions and is widely used. As a kind of coupling products, the wind power coupling is required to have the require...
