Abstract

A fiber enforced resin based compound material transmission shaft pertains to a compound material transmission shaft, and is mainly applied to the transmission systems and precision instruments of such fields as mechanics industry, aviation industry and aerospace industry. The invention solves the problems of the existing compound material transmission shaft, such as poor high temperature resistance, abrasion resistance, humidity resistance, salt spray resistance, and impact resistance, etc. The invention comprises a structure layer, a surface layer (1), and a lining layer (3); the structure layer is a hollow shaft body (2) made of fiber enforced resin based compound material, the lining layer (3) and the surface layer (1) are respectively stuck on the inner surface and the outer surface of the hollow shaft body (2) made of fiber enforced resin based compound material. The invention has the advantages of high temperature resistance, abrasion resistance, corrosion resistance, comparatively strength and hardness, humidity resistance, salt spray resistance, and impact resistance, etc.

Description

technical field [0001] The invention relates to a composite material transmission shaft, which is mainly used in transmission systems and precision instruments in the fields of machinery, aviation, aerospace and the like. Background technique [0002] The composite drive shaft is a structural part used to transmit dynamic loads such as torque. It is widely used because of its high specific strength, high specific stiffness, excellent vibration damping, fatigue resistance, and corrosion resistance. However, the prior art does not provide a fiber-reinforced resin-based composite transmission shaft, and the composite transmission shaft in the current technology only has a structural layer, without an inner lining layer and an outer layer, and has poor high temperature resistance, poor wear resistance, and heat and humidity resistance. Poor, poor salt spray resistance, poor impact resistance. Contents of the invention [0003] In order to solve the problems of poor high tempe...
