Abstract

The invention discloses a turbine rotor balance test clamp and a balance test device. The turbine rotor balance test clamp is used for clamping a turbine rotor assembly on a balance machine for a balance test, and a force application device exerts pressure on the turbine rotor assembly to enable the turbine rotor assembly to reach preset pressure in the working state of an engine; the pressure is kept stable and not reduced by means of a locking device, and then the force application device is removed; the balance machine is used for carrying out the balance test on a turbine rotor. According to the turbine rotor balance test clamp and the balance test device, the actual stress condition of the turbine rotor during operation of the engine is simulated so that balance data of the turbine rotor can be accurately measured through the balance machine, and the technical problems that a balance test clamp in the prior art cannot obtain true and accurate balance data is solved.

Description

technical field [0001] The invention relates to the field of aero-engine assembly, in particular to a turbine rotor balance test fixture and a balance test device. Background technique [0002] Aeroengine power or gas turbine rotor assembly (rotor with blades) must be balanced before being assembled into the engine to simulate the state of the rotor assembly when the engine is working, and check the balance of the high-speed rotation of the rotor assembly. Generally, the unbalance of the rotor is required to be less than 5g / mm. The turbine rotor rotates under force when the engine is working, so when doing a balance test on the turbine rotor, a certain pressure should also be applied to the turbine rotor, and the balance test should be done at the same time. The current balance test is only for the balance test of the turbine rotor assembly, without really simulating the balance test of the turbine rotor assembly under the working condition of the engine, which may not obt...
