Sliding bearings in the work due to contact between the journal and the bearing pad will produce friction, resulting in surface heat, wear and even "killed", so the design of bearings, should be used to improve the friction of the sliding bearing material bearing, select the appropriate lubrication And the use of appropriate supply methods to improve the bearing structure to obtain thick film lubrication.
1, tile surface corrosion: spectral analysis found that non-ferrous metal element concentration anomalies; iron spectrum in the emergence of many non-ferrous metal components of sub-micron wear particles; lubricants moisture exceeded, acid value exceeded.
2, journal surface corrosion: spectral analysis found that iron concentration anomalies, iron spectrum has many iron components of submicron particles, lubricating oil moisture or acid value exceeded.
3, journal surface tension: iron in the iron cutting grain or black oxide particles, the presence of metal surface tempering color.
4, tile back fretting wear: spectral analysis found that iron concentration anomalies, iron spectrum in many iron components submicron wear particles, lubricating oil moisture and acid value anomalies.
5, the bearing surface strain: iron found in the cutting abrasive, abrasive composition of non-ferrous metals.
6, tile surface peeling: iron spectrum found in many large size fatigue flaking alloy wear particles, layered abrasive.
7, bearing burning tile: iron spectrum in the larger size of the alloy abrasive and ferrous metal oxide.
