Light aviation bearing rod piece and producing method thereof

Abstract

The invention relates to a light aviation bearing rod piece. The light aviation bearing rod piece comprises two bearing members, two inner liners, a metal shaft sleeve and a tubular covering layer, wherein the two side surfaces of each bearing member are embedded into the two opposite inner liners respectively to form a round tubular pull rod structure; the bearing members and the inner liners are covered with the tubular covering layer; lug piece parts are arranged at the two ends of the bearing members respectively; drop-shaped through holes are formed in the lug piece parts; the metal shaft sleeve is arranged in the through holes; a plurality of annular longitudinal grooves are longitudinally formed in the outer surface of the metal shaft sleeve, and a plurality of transverse grooves which are distributed at equal intervals along the circumference of a round through hole are transversely designed. Compared with the prior art, the light aviation bearing rod piece has the advantages that the producing method is simple and convenient, the bearing capacity is high, and the like.

Description

technical field [0001] The invention relates to the technical field of lightweight composite materials, in particular to an aviation lightweight bearing bar and a manufacturing method thereof. Background technique [0002] For structural manufacturing technologies in the fields of aviation, aerospace, automobiles, rail transit vehicles, etc., the load-bearing structural parts can adapt to more severe environmental conditions, such as large temperature difference changes between low and high temperatures, vibration, fatigue, etc. , is an urgent need for the development of today's new technologies, especially lightweight can make energy-saving technical features generate new market competitiveness. [0003] At present, most of the structural rods used in the fields of aviation, aerospace, automobiles, and rail transit are metal materials, and steel (using forged steel parts) is especially common. In order to maintain the structural functions and load-bearing conditions, engine...

AI Technical Summary

Problems solved by technology

[0007] 1) The metal structure cannot be optimally designed for anisotropy, and the previous composite materials cannot take into account the characteristics of anisotropic carbon fiber composite materials, cannot make full use of the material properties, and the weight of the components themselves is too heavy;

[0008] 2) There are weak links in the connection between the metal and the carbon fiber composite material at the key bearing part, which affects the bearing capacity of the component;

[0009] 3) When the geometric size of the component is small, the stiffness involved often fails to meet the requirements due to the different weaving methods of the fibers;

[0010] 4) The manufacturing technology is targeted, and the cost is relatively high, so it is necessary to further optimize the design to reduce the manufacturing cost
