Friction vibration mainly refers to the abnormal vibration of rolling bearings, the general friction prone to vibration in the large ball bearings, lubricated by grease especially grease lubrication performance is not good, are more likely. Rolling bearing friction and vibration generated is often directly related to the lubricant nature. When bad or dirty lubricant performance, prone to friction and vibration, but also related to the quality of the the Rolling outer raceway processing, this special precision machining, and better able to control friction and vibration.
Rolling vibration is basically caused by the vibration of the bearing rings, with the bearing structure, rigidity, precision manufacturing, installation conditions, and the use of such factors. If the rolling bearing inner ring raceway have larger radial corrugated when the rotation of its inner ring bearing outer ring radial vibration. Bearing inner corrugated not only cause the radial vibration of the outer ring, and will also cause the outer ring of the axial vibration, the bearing will be subjected to axial load of the bearing, the outer ring of the axial relative position is changed, so in the bearing outer ring when the inner ring rotation will produce axial vibration mouth vibrating sieve in the job, for the high speed rotation of the bearing, since the vibration frequency caused by the bellows, may be equal to the rotational frequency of the exciter shaft, which produce the resonance.
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 rolling 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 of rolling bearing failure is very significant impact. Example: peeling, creasing, corrosion, cracks, wear, etc. will be reflected in the the bearing vibration detection in measuring device (through the use of special bearing vibration frequency analyzer and vibration analyzer) measuring the size of the vibration frequency distribution inferred the abnormal vibration measured values due to the self-aligning roller bearings use premise or sensor installation location different need to advance the measurement value of each machine were analyzed and compared scale determined after judge.
