Problems solved by technology
[0004] In the process of testing the motor shaft, due to the need to test multiple angles, the distance between the test device in multiple directions and the shaft is also an important factor affecting the eccentricity detection of the motor shaft. Once an error occurs, it will lead to a failure in the eccentricity detection. allow

The invention provides a semi-intelligent eccentricity detection system based on motor operation, relates to the technical field of motor detection, and aims to solve the problems that in the testing process of a motor rotating shaft, the distance between a testing device in multiple angles and multiple directions and the rotating shaft is an important factor influencing eccentricity detection of the motor rotating shaft, and once an error occurs, eccentricity detection is not accurate. The system comprises a bearing base, the bearing base is of an L-shaped structure; a motor is transversely and slidably mounted at the right end of the top plane of the bearing base; a door-shaped detection frame is vertically mounted on the bearing base on the left side of the motor in the longitudinal direction; and a test box is vertically and fixedly mounted at the left part of the front end edge of the top plane of the bearing base. The T-shaped guide groove is longitudinally formed in the middle of the side wall of the left end of the guide clamping sleeve, the detection column can slide in the guide clamping sleeve and make contact with the motor rotating shaft in three directions, and the eccentricity of the rotating shaft can be detected in an omnibearing mode.
Description
technical field [0001] The invention relates to the technical field of motor detection, and more specifically relates to a semi-intelligent eccentricity detection system based on motor operation. Background technique [0002] Due to reasons such as manufacturing, assembly or operation, the air gap between the generator stator and rotor will cause a certain degree of unevenness, resulting in a larger air gap on one side and a smaller air gap on the other side. This phenomenon is called air gap eccentricity. . Such unevenness of the air gap may appear not only in the radial direction but also in the axial direction. For example, the rotor of the hydro-generator may have a certain axial displacement under the long-term impact of the water head, which will cause the axial air gap between the stator and rotor to be small at one end and large at the other end, resulting in static axial eccentricity of the air gap. [0003] At present, there are many methods for measuring generat...
