Heilongjiang baishan bearing manufacturer summary of bearing fault four stages of development

Heilongjiang baishan bearing manufacturer summary of bearing fault four stages of the development of the rolling bearing fault of four stages: corresponding to the structure of the rolling bearings of rolling bearing has four kinds of problem frequency: rolling bearing frame with frequency, rolling bearing fault frequency, roller rolling bearing outer ring fault frequency, roller bearing inner ring with frequency. About the bearing fault frequency calculating, specially the mathematical formula, but the computation in the practical work to match, more bento is specially used in software to achieve, such as software function with the plugin, simply enter the bearing model and consumer information such as the manufacturer, they can get the corresponding frequency of all kinds of bearing faults. The first stage, that is, high temperature bearing beginning present problem of infancy, when temperature is normal, normal noise and vibration velocity and total spectrum is normal, but the peak signs, total energy and spectrum reflect the initial stage of bearing faults. When the real bearing fault frequencies present in ultrasonic period of approximately 20 - 60 KHZ range. Increases slightly in the second stage, the temperature is normal, noise, vibration velocity increases slightly, total vibration frequency change is not obvious, but the peak energy has a big increase, spectrum is also increasingly outstanding. At this time of the bearing fault frequency is presented in about 500 hz - 2 KHZ range. The third stage, the temperature is a little higher, but the ear heard the noise and vibration velocity has a large amount of increase, and the vibration velocity spectrum clearly visible on the bearing fault frequency and its harmonics and sideband, the other on the vibration velocity spectrum noise significantly elevated horizon, rush total energy compared to the second stage is becoming larger, spectrum is also increasingly outstanding. At this time of the bearing fault frequency is presented in about 0 1 KHZ range. Initiative late in the third phase change bearing, so at this time should be used to appear to the naked eye can see the rolling bearing fault characteristics such as wear and tear. The fourth stage, the temperature rise obviously, noise intensity changes, the total amount of vibration velocity and vibration displacement increases obviously, bearing defect on the vibration velocity spectrum frequency beginning, broadband high frequency noise is more random horizon; Total peak energy increases rapidly, and may show some unstable change. Must not be allowed bearing in trouble in the fourth stage of operation, otherwise will be catastrophic destruction.
