INA bearings how to check the fault in the operation and processing

1. Is first and foremost be identified according to the voice of the rolling bearing and check we can adopt the measuring apparatus, the size and quality of INA bearings rolling sound in operation to check. Due to damage, such as bearing even with slight detachment also emits an exception and irregular, and thus with the sound of the measuring device can distinguish, have the effect of early prevention. 2. Second bearing vibration in the operation to identify inspection INA bearing vibration is very sensitive to bearing damage. Such as peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, therefore, through the use of special bearing vibration zhangs gauge ( Frequency profiler, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal condition in detail. Measured values of bearing or sensor installation position and different using conditions, and thus needs prior to each machine stop after certain discriminant analysis compare measurement value of specification. 3. Finally according to the temperature of the bearing to check the temperature of bearing, according to the bearing, the outdoor temperature can fathom out, if used oil hole can directly measure temperature of bearing outer ring, is more appropriate. Usually, INA bearing temperature with running start gradually rise, 1 - Two hours later to reach steady state. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load. If smooth, device is appropriate, bearing temperature will rise sharply, can present abnormal high temperature, then must stop and take the necessary precautions. On the basis of a large number of test data. Because the temperature is smooth, speed, load, the influence of the environment, temperature range of values in the table only said roughly. Using thermal device can monitor the working temperature of bearing, and completes the temperature value beyond rules automatic alarm or stop to avoid burning shaft accident attack. Turn the INA bearing, should be very smooth without sound, also should not have impurities. Imported bearing in the work to allow running noise slightly, if you have any abnormal noise or excessive noise or sound, suggests that the bearing failure. Bearing anti-rust treatment using a slight aroma of anti-rust oil, and the dosage is not big. Make the whole bearing clean fragrance. Bearing in the horizontal plane and vertical plane junction with fine chamfering, and has a dark side. Bearing in the process of normal use, bearing installation of bearing parts allowed to have a certain temperature, when the hand touch body shell, should not feel hot as normal. If the bearing use process temperature is too high, can consider to lubricating oil quality meets the requirements or metamorphism, the high viscosity of lubricating oil; Or install the assemble tight, bearing assembly too tight; Bearing cage or rolling body fracture, etc. Rolling bearing noise can be caused by many reasons, one is the bearing inner and outer surface wear. Again, INA bearing lubrication is insufficient, form the dry friction, and bearing broken etc all make abnormal noise.
