Abstract

The invention discloses a visual detection device for motor vibration tests and a stability adjusting method. According to the visual detection device, a damper is mounted on a motor. A lower computer, a host computer and at least one acceleration sensing module are comprised, the acceleration sensing module is fixedly mounted on the surface of the damper and is used for transmitting the acquired data to the lower computer, the lower computer is for calculation of the data, a kalman filtering algorithm is utilized to carry out data processing, each corresponding acceleration value is acquired, the host computer and the lower computer are in communication connection, a processing application program capable of processing the acceleration values is comprised, a wave-shaped curve map is drafted and is displayed on a screen, and stability of the motor is adjusted through employing the adjusting method on the basis of the detection device. Through the device and the method, readability and comparability of the data can be greatly improved, difference among the acceleration values can be visually observed and compared, quality of each position of the damper can be accurately increased or reduced, so vibration of positions of the motor tends to be consistent, influence of vibration on the work condition can be reduced, and service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of vibration test detection of a motor shock absorber, in particular to a visual detection device and a stability adjustment method for a motor vibration test. Background technique [0002] The motor will vibrate during operation. On the one hand, the vibration will aggravate the wear of the components inside the motor, and on the other hand, it will cause unstable axial or radial loss to the load. In order to slow down the vibration of the motor, a shock absorber is usually connected with the motor to moderate and attenuate the vibration of the motor, thereby prolonging the service life of the motor. The shock absorber is usually adjustable so that after being installed on the motor, the vibration at each position of the motor tends to be consistent and balanced. Therefore, it is necessary to design a device and method that can conveniently and clearly display the vibration of each position of the motor sh...
