Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but not as a basis for any limitation of the present invention.

[0030] Such as figure 1 , an aviation cushioning rubber gasket, comprising a gasket main body 1 and a hollow cavity 3, the surface of the main body 1 is provided with a warp-knitted reinforcement layer 2, and the main body 1 is also provided with an installation hole 4 communicating with the hollow cavity 3 . The washer main body 1 and the warp-knitted fabric reinforcement layer 2 are flatly bonded together with an adhesive. The hollow cavity 3 is an annular cavity with an "O" cross-section. The upper part of the section of the washer main body 1 is semicircular, and the lower part is rectangular. The four mounting holes 4 are evenly distributed on the inner side of the washer main body 1 .

[0031] The above-mentioned rubber gasket is made of silicone rubber that is resistant...

Abstract

The present invention discloses an aviation buffer rubber gasket and a production method thereof. According to the present invention, a silicon rubber with characteristics of ozone resistance, atmospheric aging resistance, excellent high temperature performance and excellent low temperature performance is selected as the material when the gasket main body is produced; a knitting fabric reinforced layer is wrapped on the gasket main body surface; during the manufacturing process, the crystal whisker reinforced dissolved slat mold core is added, such that the model problem of the cavity in the gasket main body is solved; the suitable temperature zone of the aviation buffer rubber gasket achieves -50-250 DEG C, the self-weight is reduced by 20%, and the vibration transmission is reduced by 80%; and the aviation buffer rubber gasket has characteristics of ozone resistance, improved atmospheric aging resistance, substantially-prolonged flying life, substantially-prolonged maintenance cycle, and aircraft repair and maintenance cost reducing.

Description

technical field [0001] The invention relates to an aviation buffer rubber washer structure and a processing method thereof, belonging to the technical field of rubber products and processing thereof. Background technique [0002] In the process of aircraft design, in order to reduce the vibration transmission of the engine inlet and outlet air passages and ensure the normal operation of the instrumentation in the aircraft, it is necessary to provide reliable buffer protection for relevant parts, which involves the design and manufacture of related buffer devices. work. [0003] In the past aircraft design, due to the limitations of materials and process methods, the demand for buffer devices was limited to meet the use, and the guarantee for the structure and durability of the product was often insufficient, and the product had poor functionality, complex structure, and short flight life. The replacement process is cumbersome and the maintenance cost is high. In the design...
