Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] see figure 1 , the following takes a propeller with 4 blades as an example, such as figure 1 , the entire metal shaft is composed of the base 1 and the slot 2, which is directly processed by integrated processing technology. During the forming process, attention should be paid to the line shape and the position distribution of the slot 2 to reduce the amount of post-processing.

[0027] The composite material is a carbon fiber / epoxy resin material, in which the carbon fiber composite material is used as a layer material, and the epoxy resin plays the role of bonding the carbon fiber.

[0028] The slot 2 has a certain angle with the axial direction and the base 1, and the axial angle of the slot and the base is consistent with the inclination angle of the blade root; this is conducive to the rotation of the blade 3 in the slot 2 At the same time, due to the effect o...

Abstract

The invention provides a composite material propeller, comprising: a base made of metal as a whole and a plurality of slots connected together; wherein the slots are equally distributed on the circumference of the base, the opening of the slots is upward, and the spiral The root of the shaped paddle fits closely with the card slot. Based on the problems that metal material propellers are heavy and easy to corrode, and the common problem that the connection between composite materials and metal materials is easy to debond, the present invention designs the connection structure between the composite material propeller blade and the metal frame, effectively avoiding the problem caused by composite materials and metal materials Product defects occur due to poor adhesion of the frame, which improves the success rate of the product.

Description

technical field [0001] The invention relates to the technical field: a composite material propeller, in particular to a connection structure between a composite material propeller blade and a base. Background technique [0002] In recent years, metal propellers have gradually been replaced by propellers made of other materials due to their heavy weight, easy corrosion, and high noise. Among them, composite propellers are getting more and more attention due to their light weight, high strength, corrosion resistance, and low noise pollution. Applications. Composite material propellers are propellers made of composite materials or partly made of composite materials. Compared with conventional metal propellers, composite materials can reduce weight, resist fatigue, facilitate loading and unloading maintenance, and achieve vibration and noise reduction. At the same time, effective The service life is prolonged and the cost is saved. [0003] However, the current composite mater...
