The metallurgical quality of the bearing material used to be the main factors failure of the INA bearings for early . Followed by metallurgical technology (such as bearing steel vacuum degassing, etc.) to improve the quality of raw materials is improved.
The proportion of the raw material quality factor in the overall eccentric bearing failure analysis has been significantly decreased, but it still is one of the main factors bearing failure. The selection of the adequacy of the still bearing failure analysis must be considered factors.
Bearing failure analysis of the main tasks is based on a lot of background material, analyzing data and failure modes, to identify the main factors for INA Bearing failure, so that targeted improvement measures are proposed to extend the service of aligning roller bearings, to avoid bearing the occurrence of unexpected early failure.
Bearing vibration bearing failure effect is very significant. For example: peeling, creasing, rust, cracks, wear and will be reflected in the INA bearing vibration detection so through the use of the overall eccentric bearing vibration measuring device (frequency analyzers and vibration the size of the instrument, etc.) can measure the vibration frequency distribution inferred abnormal vibration measured values ??are different due to the use of INA bearings premise or sensor installation location required prior to the measured value of each machine to analyze comparative determined after the judgment scale.
Reasons 1: the overall eccentric bearing low precision method: selection of specified levels of precision bearings.
Reasons 2: the spindle bent or Holes heart method: repair spindle or box.
Reasons 3: belt pull method: adjust the belt so that the elastic proper.
Reasons 4: poor lubrication method: selection of the required grades of lubricating materials and properly cleaned.
Reasons 5: low method of assembly quality: improve the quality of assembly.
Reasons 6: the bearing shell laps method: replacement of bearings and wear parts.
The axial force is too large: cleaning, adjusted to seal the mouth ring clearance requirements between 0.2 ~ 0.3mm, the correct impeller balance hole diameter and the checksum value of the static equilibrium.
Bearing damage: replace the INA Bearing.
