Metallurgical quality of the bearing material used to be the main factors affecting premature bearing failure. Followed by metallurgical technologies (such as bearing steel vacuum degassing, etc.) to improve the quality of the raw materials to be improved. The quality of the raw material factor in the overall eccentric bearing failure analysis, the proportion has dropped significantly, but it is still one of the main factors bearing failure. The selection is properly still bearing failure analysis of the factors that must be considered.
The main task of bearing failure analysis, is based on a lot of background material, analysis of data, and failure modes to identify the main factors causing bearing failure, in order to suggest improvements targeted measures, to extend the service period Spherical roller bearings to avoid bearing A sudden early failure occurred.
Bearing vibration bearing failure impact is significant. Peeling, for example: the indentation, corrosion, cracks, wear and tear and will be reflected in the bearing vibration detected out so overall eccentric bearing vibration measuring devices (frequency analyzer and vibration analyzer etc.) can be DD out to determine the magnitude of the vibration is inferred by the frequency distribution of the measured values of the abnormal vibration due to bearing premise or sensor mounting position different therefore requires prior to analysis and comparison of the measurement value of each machine judgment scale.
1 reason: the overall accuracy of the eccentric bearing low METHODS: specified accuracy class of bearings
2 reasons: different spindle bent or cabinet hole heart: repair spindle or box
3 reasons: belt too tight: Adjust the belt so elastic proper
4 reasons: poor lubrication methods: and proper cleaning choice provisions grades of lubricating materials
5 reasons: assembly quality low method: to improve the quality of assembly
6 reasons: the bearing shell lap: replace bearings and wear parts
7, the axial force is too large: cleaning, the tone positive seal ring clearance requirements between 0.2 ~ 0.3mm, correct impeller balance hole diameter and verify static equilibrium value
8, bearing damage: replace bearings.
