Motor rotor intelligent deflection test system

Abstract

The invention relates to a motor rotor intelligent deflection test system. The system comprises a testing machine, a deflection test apparatus arranged on the testing machine and an assembly driving a motor stator to rotate. The deflection test apparatus comprises an axial laser displacement meter, a first displacement sensor transmitting displacement signals to the axial laser displacement meter, a radial laser displacement meter, and a second displacement sensor transmitting the displacement signals to the radial laser displacement meter. The axial laser displacement meter and the radial laser displacement meter are arranged on the bench surface of the testing machine, the assembly driving the motor rotor to rotate is arranged below the bench surface of the testing machine, when the assembly driving the motor rotor to rotate drives the motor rotor to rotate, the axial laser displacement meter can detect deflection displacement in a rotation axial direction, and the radial laser displacement meter can detect deflection displacement in a radial direction. The system has the advantages of high test result accuracy and good stability.

Description

technical field [0001] The invention belongs to the field of motor rotor testing, and in particular relates to a motor rotor intelligent deflection testing system. Background technique [0002] For judging the dynamic quality characteristics of components such as fan blades or shafts at operating speeds, deflection is an important reference index parameter. The sources of dynamic deflection include shaft center offset, unbalance, and geometric tolerances. The lower deflection The amount can represent the higher the stability of the rotating shaft at high speed, the smaller the noise and vibration. [0003] At present, when the commonly used deflection test system is used to test the rotating shaft to be tested, the measurement surface is generally a common continuous surface measurement, but the discontinuous surface structure of the fan blade cannot be measured, which makes the measurement accuracy and stability of the system low. .
