A bonded glass fiber reinforced plastic drive shaft with form-surface fit and its production process

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.
