Knowledge of inspection - bearing INA bearings' faults

INA bearings in use process because of itself quality and external conditions, the bearing capacity, rotational accuracy and wear-resisting performance will change. When INA bearing performance index is lower than the use requirement and when not working, INA bearing malfunction or even failure happened, INA bearings in the event of failure after accidents, machinery and equipment will be shut down, has function loss and other anomalies, so need to find out in a short time causes, and take corresponding measures. To make the INA bearing in good condition to maintain proper performance and use for a long time. Must carry on the inspection and maintenance of INA bearings, inspection and maintenance to prevent failure is very important, in the work to review the rumbling of INA bearings, vibration, temperature, and the lubricant. 2. INA bearing vibration INA bearing vibration effect on the failure of INA bearings is obvious. For example, peeling, indentation, rust, crack and wear will be reflected in the INA bearing vibration testing, so through the use of special INA bearing vibration measurement device ( Frequency analyzer and vibration meter, etc. ) Can measure the size of the vibration, through frequency distribution can be concluded that the concrete situation of the abnormal vibration, the measured value of INA bearings or sensor installation position and different using conditions, thus requiring prior to each machine after the analysis and comparison the measured value of decision criteria to determine. 3. INA bearing temperature usually INA bearing temperature as operation began to rise slowly, and reach the stable state after 1 to 2 hours. INA bearing the normal temperature of heat capacity, heat dissipating capacity, rotational speed and load of machinery. If the lubrication, installation is not appropriate, the INA bearing temperature will go up sharply, there will be unusually high temperature, then must stop and take the necessary precautions. 4. Lubricant lubrication of rolling INA bearing fatigue life and the friction, wear, temperature rise, vibration, etc have important influence, not normal lubrication, and can't work INA bearings. Analyzes the damage reasons of INA bearings shows that about 40% of the INA bearing damage is related to bad lubrication. Therefore, INA bearing lubrication is an effective measure to reduce the INA bearing friction and wear. In addition, the INA bearing lubrication also impact of the heat dissipation, rust, sealing, etc. To ensure that the lubricant can't expired, selection are correct. Harvester INA bearing grease lubrication points, lubrication and two, big gear box oil lubrication select use GL - 5 80 w90 gear oil; Grease lubrication mos2 is commonly used in lithium base grease, lubrication increased torsional device stepless lower device must use mobil grease lubrication XHP222 or better.
