The four stages of rolling bearings' faults

Rolling bearings use is more common in the transmission machinery and equipment, it is also easy to destroy one of the components. Lot of rotating machinery fault and rolling bearing, bearing of the advantages and disadvantages of mechanical equipment running state has great influence, its shortcomings can cause abnormal vibration and noise cause machinery and equipment, serious and even destroyed equipment. Rolling bearing fault of four links: match the structure of the rolling bearing, roller bearing fault: there are four ball bearings rolling bearing fault, rolling, rolling element bearing fault rolling bearing outer ring fault, fault rolling bearing inner hole. The beginning of the first stage, that is, bearing malfunction bud link, the temperature at this time everything is normal, normal noise, vibration rate of total output and spectrum everything is normal, but the peak speed and frequency have certain warning, reflect the original link of bearing failure. The second stage, the temperature is normal, slightly expanded the noise and vibration velocity output slightly expanded, vibration frequency shift was not significant. The third stage, the temperature is rising slightly, but the ear heard the noise, vibration rate increase, the rate and vibration frequency clearly visible on the bearing fault frequency and harmonic current, the other a marked increase in the rate of vibration frequency noise, rotating speed compared to more and more in the second stage, frequency, also be highlighted. The fourth stage, significant temperature rise, noise significantly changes, the compressive strength of the vibration velocity and vibration displacement significantly expanded, bearing failure frequency vibration rate frequency just began to fade, speed noise rapidly expand, and there will be some unstable shift. In addition to special circumstances can't keep the bearing in the fourth stage of fault development, otherwise will produce very big effect to machinery and equipment. Above is the content of the bearing to share today, want to learn more bearing small knowledge, pay attention to the bearing's official website.
