Balancing tool for combined rotor and stator

Abstract

The invention discloses a balancing tool of a combined rotor and stator. The balancing tool comprises a deep groove ball bearing seat (1), a deep groove ball bearing (2), a balancing machine transmission shaft sleeve (3), a rolling rod bearing seat (4), a rolling rod bearing (5) and a flange plate (6). The deep groove ball bearing (2) is connected with the deep groove ball bearing seat (1); the rolling rod bearing (5) is connected with the rolling rod bearing seat (4); the deep groove ball bearing seat (1) is connected with the rolling rod bearing seat (4) through the balancing machine transmission shaft sleeve (3); and the rolling rod bearing seat (4) is connected with the flange plate (6). According to the invention, the problem of deviation between the dynamic unbalance amount and the detection value caused by secondary assembly of the engine rotor assembly is solved, so that the detection value of the dynamic unbalance amount in the production or repair process is kept consistent with the dynamic unbalance amount of the rotor in the final working state of the engine to the maximum extent; and in the balancing process, the influence of the rear bushing when no stator is arranged for balancing is avoided, repeated disassembly and assembly work is not needed, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of engine assembly, in particular to a balance tool with combined rotor and stator. Background technique [0002] Based on the problem of vibration of aero-engines in the working state in the actual production and maintenance process, there are phenomena-level problems. The main reason for the large vibration of the engine is that the unbalance of the rotating parts is too large. Under the high-speed motion of tens of thousands of revolutions per minute, the actual unbalance will be magnified hundreds of times compared with the unbalance measured during the manufacturing or maintenance process. [0003] There are currently the following challenges in reducing engine vibration: [0004] 1) The structure of the aero-engine is complex, including tens of thousands of components, and the assembly accuracy of each component will affect the final vibration of the engine; [0005] 2) The rotor assembly will be ass...
