Problems solved by technology
[0002] First of all, the connection method between the support nut and the support ring in the flame tube in the traditional scheme is welded connection, but due to the narrow space, the welding is difficult, and it is very difficult to replace once it fails; secondly, because the self-locking nut has a certain degree of freedom, so It is not easy to locate during welding, and it is easy to cause deformation of the support ring in the flame tube during the welding process; in addition, the existing support nut uses a locking plate to prevent rotation, but due to the limited anti-rotation torque of the locking plate, it is easy to appear during the disassembly process of the self-locking nut. The locking plate is deformed, the anti-rotation fails, and the bolt cannot be disassembled

The invention belongs to the field of aero-engine design, and particularly relates to a supporting plate nut structure convenient to replace, which comprises a self-locking nut, the center of the self-locking nut is provided with a through round hole, and the inner wall of the round hole is provided with a thread; the outer wall of the self-locking nut protrudes in the circumferential direction to form a plate-shaped supporting plate, and the supporting plate divides the self-locking nut into a cylindrical cylinder and a prismatic prism. The locking plate is provided with the self-locking nut, the locking plate is in a sheet shape, the two ends of the locking plate are bent inwards to form turned edges, a gap is formed between the turned edges and the non-bent part of the locking plate, and the supporting plate is contained in the gap; a square hole for accommodating the prism is formed in the center of the locking plate; the edge of the square hole is provided with a clamping jaw which is bent outwards; therefore, the problems that the supporting plate nut is difficult to disassemble and assemble and the inner supporting ring is deformed during welding are solved; in addition, a traditional structure for preventing rotation through a locking plate is improved and designed into a structure for preventing rotation through cooperation of the self-locking nut and the inner supporting ring, so that the anti-rotation performance is improved, and the disassembly and assembly reliability of the supporting plate nut is improved.
