Affect SKF spherical bearings of normal operation troubleshooting note

Metallurgical quality of spherical SKF bearing material used to be the main factors affecting the early failure of rolling spherical SKF bearings. As metallurgical technology (bearing such as vacuum degassing of steel) progress, improvement in the quality of raw materials. Raw materials quality factors of failure analysis of spherical SKF bearings share has decreased significantly, but it remains one of the main influential factors of failure of rolling bearings. Material adequacy remains spherical SKF bearings failure analysis of factors that you must consider.
1. outside spherical SKF bearing in using process in the due to itself quality and external conditions of causes, its hosted capacity, and rotating precision and wear performance, will occurred changes. Dang bearing of performance indicators below using requirements and cannot normal work Shi, outside spherical SKF bearing on occurred has fault even failure, scroll bearing once occurred failure, accident situation Hou, machine, and equipment will will stopped go, appears features lost, various exception phenomenon, therefore needs in short-term within identified occurred of causes, and take corresponding of measures.
2. bearing vibration
Bearing of vibration on bearing of failure effect is clear. such as: peeling, and pressure trace, and rust, and crack, and wear, will out spherical SKF bearing vibration detection in the reflect out, so through used special of scroll outside spherical SKF bearing vibration measurement device (frequency Analyzer and vibration instrument,) can measurement out vibration of size, through frequency distribution can inferred out exception vibration of specific situation, measuring was of numerical due to outside spherical SKF bearing of using conditions or sensor installed location, and different, Therefore require prior to analysis and comparison of measurement values of each machine after the test.
3. the temperature of the bearing
Typically spherical SKF bearing the temperatures slowly rise as the operation began, 1-2 hours to stabilize. the normal temperature of the bearing due to the heat capacity, heat dissipation, speed of the machine and load another. If lubrication, installation doesn't fit, then insert SKF bearing temperature to rise quite sharply, abnormal high temperature appears, then you must stop and take the necessary precautions.
