Since the invasion of dust and pollutants relative movement of the rolling elements and raceways, the raceway surface rolling and wear. The wear amount is larger, increasing the vibration, noise, bearing, reduce the bearing′s running precision, which directly affect the accuracy of some host. The FAG bearings some silent machinery, daily maintenance is the main pollutant dust intrusion prevention.
1, influence on bearing life
Cleanliness of bearing for roller bearing life of great influence, FAG bearings has therefore conducted a special test, the result is the difference of several or even dozens of times times. Cleanliness of bearing higher, showed longer et al: effects of different oil cleanliness of ball bearing life great. Therefore, improving the cleanliness of the lubricant can prolong the life time of the bearing, in addition, lubricants containing dirt particles below 10um, bearing life into several fold increase.
2, the influence of vibration and noise
The test results show that bearing test center: cleanliness seriously affect the vibration level of FAG bearing, especially high-frequency vibrations more significant. Cleanliness of high speed bearing vibration value is low, especially in the high frequency band, did a test on the effect of needle roller bearing grease dust on the noise, the more the greater noise proof dust.
3,′s effect on lubrication performance of the decline of FAG bearing cleanliness, not only affect the lubricant film formation, will also cause the modification of lubricating greases and accelerate the aging, thus affecting the decline in the performance of the grease.
