The invention discloses a composite transmission shaft and a forming technology of the composite transmission shaft. The composite transmission shaft comprises a hard foam pipe, two metal flanges and a composite shaft pipe, wherein the metal flanges are fixedly arranged at the two axial ends of the hard foam pipe in a sleeving manner; the composite shaft pipe is wound on the metal flanges and the peripheral wall of the hard foam pipe through rubberized fibers and is formed through heating and curing; according to the composite transmission shaft, in the winding forming curing process, the fiber-enhanced resin composite shaft pipe is formed and is connected with the metal flanges, connection is stable and reliable, the connecting strength is high, the material waste problem caused by shaft pipe secondary cutting and connecting traces caused by secondary connection and forming are avoided, due to arrangement of the hard foam pipe, the whole rigidity and the silencing and vibration resistance properties of the composite transmission shaft can be improved, during mold assembling, a metal core shaft can be inserted in the hard foam pipe for positioning, and the composite transmission shaft can be applied and popularized in fields of automobiles, ships, wind power generation parts and the like.
Description
technical field [0001] The invention relates to the technical field of machining, in particular to a composite transmission shaft. In addition, the invention also relates to a molding process of a composite material transmission shaft. Background technique [0002] At present, a composite transmission shaft used in the automobile market is formed by connecting a composite shaft tube and metal flanges arranged at both ends of the shaft tube, and has good mechanical properties. [0003] Among them, a typical connection method between the shaft tube and the metal flange is the cementing method. The cementation method is difficult to ensure the full filling of the adhesive layer, which in turn affects the stability of the bond strength. [0004] Therefore, how to ensure the stability of the connection between the shaft tube and the metal flange is a technical problem to be solved by those skilled in the art. Contents of the invention [0005] In view of this, the object of ...
