Journal sliding bearing in at work, contact with the bearing bush of the conflict, the wear appearance fever, even "killed", so when planning bearing, should choose sliding bearing material manufacture with good sex of anti-friction bearings, choose suitable lubricant and adopt appropriate measures for the supply of improving the structure of the bearing for thick film lubrication, etc.
1, tile surface corrosion: spectrum analysis found that abnormal non-ferrous metal element concentration;Iron spectrum presented many nonferrous metal composition of sub-micron wear particles;Lubricating oil water overruns, acid value, overspending.
2, shaft neck appearance corrosion: spectrum analysis found that abnormal iron concentration, there are a lot of iron in iron spectrum of submicron particles, oil water overruns or acid value overruns.
3, a shaft neck appearance strain: iron spectrum have iron series cutting grinding grain or black oxide particles, metal appearance exists heat tint.
4, tile back micro wear: abnormal spectral analysis found that iron concentration, there are a lot of iron in iron spectrum wear submicron particles, abnormal oil moisture and acid value.
5, a bearing surface strain: iron spectrum found cutting abrasive, abrasive ingredients for non-ferrous metal.
6, tile surface peeling: finds many large-scale iron spectrum fatigue peeling alloy wear particles, the layered grits.
7, bearing tile burning: iron spectrum have more large-scale alloy grinding grain and black metal oxides.
