Tapered roller bearing metallurgical quality of the materials used to be the main factors affecting the early failure of tapered roller bearings. Metallurgical technology (such as vacuum degassing of steel of bearings, etc) increases, improved quality of raw material. Raw materials quality factors in the weighting of FAG bearings failure analysis has declined dramatically, but it remains the one of the main factors of FAG bearings failure. Selection of propriety is still bearing failure analysis of essential factors for consideration.
Main tasks of bearing failure analysis, is based on the large amount of background material, analysis of data and failure mode, identifying the main factors causing failure of tapered roller bearing, to formulate improvement measures targeted, roller bearings with extended service period, avoid unexpected early bearing failure.
FAG bearings for vibration effect on bearing failure is significant, e.g. peeling, indentation, rust, cracks, Wear, will in tapered roll child bearing vibration detection in the reflect out so through used special of FAG bearing vibration measured device (frequency Analyzer and vibration instrument,) can measured out vibration of size through frequency distribution can inferred out exception vibration of detailed situation measuring was of numerical due to tapered roll child bearing of using premise or sensor installed location, and different therefore needs prior on each Taiwan machine of measured value for analysis comparison Hou determines judgment scale.
1, reason: FAG bearings precision low method: select provides accuracy of bearing
2, causes: bent or box spindle hole is not concentric: repair of spindles or box
3, reason: belt too tight methods: adjust belt tension appropriate
4, reason: poor lubrication method: use code designation of lubricating materials and properly cleaned
5, reason: assembling method of low quality: improving the quality of assembling
6, reason: within the bearing shell lapping method: replacement of bearings and related wear parts
7, was too large for the axial method: cleaning, aligning sealed mouth ring clearance requirements between 0.2~0.3mm, correction and verification of static balance hole diameter of the impeller balanced value
8, FAG bearing damage method: replace tapered roller bearings
