Disassembling and assembling device for high-pressure turbine front baffle

Abstract

The invention relates to design of auxiliary equipment for high-pressure turbines of aircraft engines, in particular to a disassembling and assembling device for a high-pressure turbine front baffle. The disassembling and assembling device comprises an assembling and disassembling ring, a supporting frame, a connecting seat, an axial load pull rod, a spline shaft, a torque amplifier, a spline transition section and an axial load nut, wherein the assembling and disassembling ring is arranged on one side of the front baffle in a sleeving mode; the supporting frame is coaxially fixed to one side of the assembling and disassembling ring; the connecting seat is located in an inner cavity of the supporting frame and fixedly connected with a high-pressure turbine disc through a fixing part of the connecting seat; one end of the axial load pull rod coaxially penetrates through a through hole of the fixing part; the axial load pull rod is coaxially sleeved with the spline shaft, the outer ring face of the spline shaft is arranged at one end of the supporting frame through a thrust ball bearing, and one end of the spline shaft is arranged in an accommodating part of the connecting seat in a matched mode through splines; the torque amplifier is coaxially and fixedly arranged at the end, away from the assembling and disassembling ring, of the supporting frame; the spline transition section is arranged between the spline shaft and the torque amplifier; and the axial load nut is arranged at one end of the axial load pull rod. By means of the disassembling and assembling device for the high-pressure turbine front baffle, torque required for assembling and disassembling of the front baffle can be stably loaded.

Description

technical field [0001] The invention relates to the design of auxiliary equipment for high-pressure turbines of aero-engines, in particular to a disassembly and assembly device for front baffles of high-pressure turbines. Background technique [0002] At present, some aero-engine high-pressure turbine front baffles adopt a boltless structure. However, there has been a lack of effective methods and devices for the assembly and disassembly of the baffle, and the assembly and disassembly of the structure can only be realized by relying on impact loads. At the current level of technology, the assembly and disassembly torque of the baffle cannot be obtained. At the same time, the assembly and disassembly of the baffle requires at least three operators to apply impact loads for multiple times. The work efficiency is relatively low, and there are certain safety hazards. In addition, the impact load of assembly decomposition will cause certain damage to the baffle, and the reaction ...

Problems solved by technology

[0002] At present, some aero-engine high-pressure turbine front baffles adopt a boltless structure. However, there has been a lack of effective methods and devices for the assembly and disassembly of the baffle, and the assembly and disassembly of the structure can only be realized by relying on impact loads.

At the current level of technology, the assembly and disassembly torque of the baffle cannot be obtained. At the same time, the assembly and disassembly of the baffle requires at least three operators to cooperate and apply impact loads many times to complete. The work efficiency is relatively low, and there are certain safety hazards

In addition, the impact load of assembly decomposition will cause certain damage to the baffle, and the reaction force of the impact load will also cause certain discomfort to the operator
