Motor field dynamic balance correction and vibration detection method

Abstract

The invention discloses a motor on-site dynamic balance correction and vibration detection method, particularly relates to the field of motor dynamic balance correction and detection, and comprises avibration detection device and a vibration detection and dynamic balance correction method. The vibration detection device comprises a base, a display, a detection mechanism, a gradienter and an installation assembly. The upper surface of the base is provided with an embedding groove. The detection mechanism is movably arranged in the embedding groove, the displayer is arranged above the embeddinggroove in a sliding mode, the gradienter is fixedly arranged at the front end of the display, and the installation assembly is arranged on one side of the base and detachably connected with a motor fixing base. According to the invention, the motor main shaft is cleaned firstly, and then the levelness between the device and the motor main shaft is adjusted through the gradienter, so that the detection accuracy of the sensor can be ensured; after the reference block and the motor main shaft are fixed, the reference block is used as a reference point to accurately find the offset distance of the points of the outer ring of the motor, so that when the points correspond to the rotor, high-precision counterweight correction can be performed on the rotor.

Description

technical field [0001] The embodiments of the present invention relate to the field of motor dynamic balance correction and detection, and in particular to a method for on-site dynamic balance correction and vibration detection of a motor. Background technique [0002] The motor running noise is mainly composed of mechanical noise, electromagnetic noise and aerodynamic noise. Practical research shows that among the three types of noise, mechanical noise accounts for 65% to 75%, electromagnetic noise accounts for about 25%, and aerodynamic noise accounts for less than 10%. The main cause of mechanical noise of the motor is the rotor imbalance of the motor. An unbalanced rotor creates a stress on its support structure and the rotor itself during rotation, causing periodic mechanical vibrations in the motor during operation. The additional dynamic pressure generated on the rotor bearings reduces shaft and bearing life. [0003] At present, when most high-speed motor rotors ar...
