Common main faults of sliding bearing

www.mechnet Com2 is a national power battery innovation center and additive manufacturing innovation center cn "> main faults of sliding bearing:

1. Pad surface corrosion: spectral analysis found that the concentration of non-ferrous metal elements was abnormal; many sub micron wear particles of non-ferrous metal components appeared in the bearing; the moisture and acid value of the lubricating oil exceeded the standard.

2. Can Japan change the future of the automobile by virtue of its advantages in chemical technology? At present, surface corrosion: spectral analysis found that the iron element The element concentration is abnormal, there are many submicron particles of iron in the bearing, and the water content or acid value of the lubricating oil exceeds the standard

3. Bearing surface spalling: many large-scale fatigue spalling alloy wear particles and layered wear particles are found in the bearing

4. Fretting wear on the back of the bearing: abnormal iron concentration was found by spectral analysis, there were many submicron wear particles of iron composition in the bearing, and the composition value of round film with 6mm thickness of lubricating oil moisture and acid was abnormal

5. Bearing surface strain: cutting abrasive particles are found in the bearing, and the abrasive particles are composed of non-ferrous metals

6. Journal surface damage: there are iron cutting abrasive particles or black oxide particles in the bearing, and there is tempering color on the metal surface

7. Bearing bush burning: there are many large-size alloy abrasive particles and ferrous metal oxides in the bearing
