Problems solved by technology

[0004] When disassembling the rotor-stator structure of the above-mentioned engine, it is mostly fixed vertically by the support mechanism, and at the same time it is axially positioned and radially centered. This kind of scheme can easily realize the rotor hub assembly 1, The disassembly and assembly of the second-stage rotor blade 3, the third-stage rotor blade 4, the first-stage stator case 5 with guide vanes, and the second-stage stator case 6 with guide vanes, but when disassembling the first-stage rotor blade 2, Since the installation mortise of the first-stage rotor blade 2 on the rotor hub assembly 1 is inclined at a certain angle to the axis of rotation, and the first-stage rotor blades 2 are overlapped by shoulders 7 , during the disassembly process, the coupling Interference will easily cause the blade to slip from the installation tenon and groove, the bleed air will collapse systematically, and friction will occur, which will cause the shoulder 7 to tear or be damaged by falling pieces, resulting in damage to the blade

Abstract

The invention belongs to the technical field of disassembly and assembly design of an engine rotor and stator structure, and particularly relates to an engine rotor and stator structure assembling anddisassembling device. The engine rotor and stator structure assembling and disassembling device comprises a support seat, a positioning shaft, a positioning cylinder, a support and a rotating device,wherein one end of the positioning shaft is connected with the support seat, one end of the positioning cylinder is connected with the support seat, the positioning cylinder and the positioning shaftare coaxially arranged, and the rotating device is arranged on the support and is connected with the support seat or the positioning cylinder so as to drive the positioning cylinder and the positioning shaft to turn over.

Description

technical field [0001] The application belongs to the technical field of disassembly and assembly design of an engine rotor-stator structure, and in particular relates to a disassembly and assembly device for an engine rotor-stator structure. Background technique [0002] The stator structure of a turbofan engine with a small bypass ratio includes a rotor hub assembly 1, a first-stage rotor blade 2, a second-stage rotor blade 3, a third-stage rotor blade 4, a first-stage stator casing with guide vanes 5, and a first-stage stator casing with guide vanes. The secondary stator casing 6, such as figure 1 shown. [0003] Considering the ease of disassembly and assembly of the engine rotor-stator structure, the assembly sequence of the above-mentioned engine rotor-stator structure is designed as follows: three-rotor hub assembly 1→secondary stator case 6 with guide vanes→secondary rotor blade 3→with guide vanes The first-stage stator casing 5 → the third-stage rotor blade 4 → th...
