Sliding bearing failure analysis

Sliding bearing failure analysis

Sliding bearing will produce the journal and bearing contact at work due to friction, resulting in surface heat, wear and even "killed", so should be used in the slide bearing lubrication of antifriction good sliding bearing materials bearing, select the appropriate the agent and the appropriate method of supply, improve the structure of the bearings in order to obtain a thick film lubrication.
1, tile surface corrosion: the spectra showed abnormal concentration of non-ferrous metal elements; many non-ferrous metal composition of submicron wear particles in the iron spectrum; excessive lubricant moisture, acid value exceeded.
2, the journal of surface corrosion: the spectra showed abnormal iron concentration and iron content in the sub-micron particles in the iron spectrum, Plastic bearingexcessive lubricating water or acid value exceeded.
3, the journal surface strain: iron cutting abrasive or black oxide particles in the iron spectrum, the metal surface tempering color.
4, tile back fretting wear: spectra showed abnormal concentration of iron, the iron spectrum many iron content in the sub-micron wear particles, oil water and acid value exception.
5, the bearing surface strain: Ferrography cutting abrasive, abrasive ingredients for non-ferrous metals.
6, the peeling off of the tile surface: iron spectrum found in many of the large size of the fatigue spalling alloy wear particles, layered abrasive.
7, there are more large-size alloy abrasive ferrous metal oxide bearing bush-burning: the iron spectrum.
