Abstract

The application belongs to the field of low-vortex rotors of engines, and in particular relates to a device for balancing a stator of a low-pressure turbine belt. Including: rotating spindle assembly, casing front support assembly and casing rear support assembly. The rotating spindle assembly includes a rotating spindle main body. A connecting portion is provided in the middle of the rotating spindle main body. The connecting portion is fixedly connected to the low-pressure turbine rotor. The low-pressure turbine rotor is connected by bolts; the front support assembly of the casing includes a front support frame, one end of the front support frame is rotationally connected with the front end of the main body of the rotating main shaft, and the other end is fixedly connected with the front end of the stator of the low-pressure turbine rotor; the rear support assembly of the casing includes a rear A support frame, one end of the rear support frame is rotatably connected to the rear end of the main body of the rotating main shaft, and the other end is fixedly connected to the rear end of the low-pressure turbine rotor stator. The application can provide support for the rotor of the low-pressure turbine, so as to ensure that the rotors and stators do not collide with each other.

Description

technical field [0001] The application belongs to the field of low-vortex rotors of engines, and in particular relates to a device for balancing a stator of a low-pressure turbine belt. Background technique [0002] In the process of researching the low-vortex rotor balancing process of the engine, it is necessary to design a special device with stator balance to realize the measurement and correction of the unbalance of the low-vortex rotor without the low-vortex shaft state. [0003] In the prior art, the balance device of the low vortex rotor is aimed at the state with the low vortex shaft, provides support for the low vortex rotor, and fixes the stator casing, and the unbalanced amount of the rotor with the low vortex shaft can be realized by using the original balance device measurement and correction. Aiming at the new technological research requirements for balancing the low-scroll rotor of the engine without a low-scroll shaft, the current device cannot meet the res...
