Aeroengine counterweight screw assembling and disassembling tool and assembling and disassembling method thereof

Abstract

The invention discloses an aeroengine counterweight screw assembling and disassembling tool and an assembling and disassembling method thereof, relates to the field of aeroengine maintenance and solves the problems that the space of a counterweight screw mounting area is narrow, and counterweight screws can only be assembled and disassembled by disassembling an original table bearing in the prior art. The technical scheme adopted by the invention is as follows: the aeroengine counterweight screw assembling and disassembling tool comprises a sleeve, a first transmission rod, a second transmission rod and a wrench head, wherein the sleeve is L-shaped; the first transmission rod and the second transmission rod are arranged in the sleeve and are connected with each other at a corner of the sleeve through a transmission structure; one end of the first transmission rod is a rotating operation end; one end of the second transmission rod is connected with the wrench head; the wrench head is provided with a clamping groove or a counter bore matched with a counterweight screw; the counterweight screw is clamped in the clamping groove or the counter bore of the wrench head, so that the counterweight screw can be assembled; and the situation that the original table bearing is repeatedly assembled and disassembled in a dynamic balance process can be avoided. The aeroengine counterweight screw assembling and disassembling tool and the assembling and disassembling method are applied to assembling and disassembling of the counterweight screws in the dynamic balance process of an aeroengine compressor rotor.

Description

Technical field [0001] The present invention relates to the field of aeroeir engine, and more particularly to an air engine compressor rotor balancing step for dispensing a dispensing tool for dispensing a weighting screw, and a dispensing method implemented by a dispensing tool. Background technique [0002] A certain aviation engine compressor rotor balancing process is a key process in repair. If the unbalanced compressor rotor is installed, the excessive remaining imbalance will cause the engine vibration, exacerbated the wear of the bearing, which will also cause serious Oil leakage, metal chip ovens and other issues. Since it is necessary to assemble the engine original bearing bearing to travel balance, the outer bearing outer bearing is large and the flange is installed, resulting in a very narrow space for the mounting area of ​​the counterweight screw, and cannot be assembled without decomposing the original bearing. . The bearing of the dispensing the original table mu...
