Motor bearing noise test methods and equipment

Motor bearing noise test method and device of the present stage test machine there are two ways of bearing abnormal sound. One kind is depending on the materials of the acoustic noise test, the other is based on vibration measurement. （ A) Noise test, noise test is a basic noise in less than 20 db noise elimination of the natural environment, the application of high quality microphone sound intensity at a certain spacing and orientation for bearing data signals, and the statistical analysis method to get the abnormal sound in the composition, measuring method is abnormal sound. （ 2) Vibration measurement vibration measurement is indirect test way of abnormal sound, and can be divided into determine the determination of main parameters and quantitative analysis method to determine the method. Among them, determine the measurement again into the abnormal sound monitoring method and observe the shock wave type method. The quantitative analysis of the parameter determination method is mainly refers to with measured in the bearing vibration signal data related to the abnormal sound of evaluation values of variables such as: vibration peak, wave soldering factors to comment on the abnormal sound of motor bearing. （ 3) Accurately measure bearing abnormal sound testing instrument precise measurement of bearing abnormal sound of testing instruments, such as: hangzhou institute of bearing experiment of BANT - 1 type bearing abnormal sound monitoring instrument; Shanghai bearing technical laboratory S092 bearing vibration ( The abnormal sound) Detector; Luoyang bearing research development S0910 - with bearing instrument factory in dalian Ⅲ. This bearing testing instrument can accurately measure the bearing vibration amplitude and main parameters can accurately measure reflect bearing abnormal sound peak, peak factor and pulse number, etc. Focus on bearing website, give you share different bearing knowledge every day.
