Problems solved by technology

[0002] During the assembly process of an aero-engine, the nuts on the rotating body usually need to be tightened with a large torque limit. Usually, the rotating body has anti-twist sleeve teeth, but some rotating bodies do not involve anti-twist due to space and structural constraints. Set of teeth, in this state, when the force is limited, the rotating body will rotate together with it and cannot be tightened with limited force

Abstract

The invention relates to a stop device of an engine rotor and stator tightened part and a use method of the stop device of the engine rotor and stator tightened part. According to the technical scheme, the device comprises a technological stator case, a rotor stop sleeve and stop pins. The rotor stop sleeve is installed in the middle of the technological stator case, and the rotor stop sleeve and the technological stator case can rotate relatively. The technological stator case is used for being connected with an engine stator case. The rotor stop sleeve is provided with an upper installation side and a lower installation side, the upper installation side is provided with first holes, the lower installation side is provided with second holes, the upper installation side is further provided with first pin holes, and the second holes and bolts on an engine rotor are installed in a matched mode to achieve connection between the rotor stop sleeve and the engine rotor; the technological stator case is provided with second pin holes, and the stop pins can be inserted into the first pin holes and the second pin holes for connecting the engine rotor with a stator together to implement stop; the first holes are used for being provided with torque multipliers and tightening a tool. By means of the technical scheme, the stop device is easy to manufacture and easy and convenient to assemble, the assembling period is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to a brake device for screwing parts of an engine rotor and a stator and a use method thereof. Background technique [0002] During the assembly process of an aero-engine, the nuts on the rotating body usually need to be tightened with a large torque limit. Usually, the rotating body has anti-twist sleeve teeth, but some rotating bodies do not involve anti-twist due to space and structural constraints. Set of teeth, when the force is limited in this state, the rotating body rotates together and cannot be tightened with limited force. For this reason, the research work on the braking device and its application method of the large torque and force limiting of the engine rotating body is carried out, and the purpose is to solve the problem of large torque and force limiting tightening of the rotating body without a reverse torsion structure through comprehensive and systematic tes...
