Since the smooth bearing during operation for the touch of shaft and bush will conflict, the appearance problems such as fever, wear even "killed", so in describing bearings, should choose anti-friction bearing material manufacture with good sex of bearing bush, comfortable and smooth agent selects the appropriate measures for the supply of improved bearing in order to obtain the layout of the thick film smooth, etc.
1, tile surface corrosion: spectrum analysis found that abnormal non-ferrous metal element concentration;Bearing presents many nonferrous metal composition of sub-micron wear particles;Smooth water overruns, acid value oil overruns.
2, shaft neck appearance corrosion: spectrum analysis found that abnormal iron concentration, there are a lot of iron in bearing component of submicron particles, smooth water overruns or acid value oil overruns.
3, tile surface peeling: finds many large-scale bearing fatigue peeling alloy wear particles, the layered grits.
4, tile back micro wear: abnormal spectral analysis found that iron concentration, there are a lot of iron in bearing components wear submicron particles, abnormal smooth oil moisture and acid value.
5, the smooth bearing appearance strain: bearing found cutting grits, grinding grain composition for non-ferrous metal.
6, composite shaft neck injury: appearance of bearing iron series cutting grinding grain or black oxide particles, metal surface heat tint.
7, bearing tile burning: there are more bearing by means of large scale, alloy and black metal oxides.
