Embodiment Construction
[0022] The structure, manufacture and assembly method of the aircraft engine transition section assembly sealing ring referred to in the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] As shown in the figure, the assembly rubber sealing ring of the V-shaped cloth frame layer (4) is composed of the sealing working surface (1), the base (2) and the secondary fixing clamp (5). The layer (3) is saturated nitrile rubber, the cloth skeleton layer (4) is polyester fiber cloth, and the secondary fixing clamp (5) is a stainless steel belt that can be tightened by self-tapping.
[0024] Its production and assembly steps are as follows:
[0025] A. Preparation of the main compound rubber: use saturated nitrile rubber as the base rubber, use peroxide as the vulcanizing agent, supplemented by other rubber additives, and mix on the rubber mixer to prepare for use.
[0026] B. Preparation of cloth raw film: Heat the mixed rubber ob...
