Check the combination of SKF bearing fault handling necessary measures in operation

From spalling, indentation, rust, crack and wear will be reflected in the combination of bearing vibration measuring, SKF bearing vibration of bearing damage is very sensitive, so, through the use of special bearing vibration measuring device (
Frequency analyzer, etc. )
Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation.
Due to the measured values of bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard.
Because SKF bearing even slightly stripping damage, such as also emits an exception and irregular, and therefore with the sound of the measuring device can distinguish, USES the sound device, the size and quality of bearing rolling sound in operation to check, have the effect of prevention in advance.
If using the oil hole can directly measure temperature, SKF bearing outer ring is more appropriate.
In general, the temperature of the bearing, generally can be deduced according to the bearing on the surface of the outdoor temperature.
If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions.
In general, the temperature of the composite bearing with operation began to slowly rise, 1 -
After 2 hours to reach steady state.
The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load.
When necessary, the use of thermal device can monitor the working temperature of bearing, and implement e. automatic alarm when the temperature is more than the household or stop to prevent the shaft accidents.
Turn the SKF bearing, should be very smooth without sound, also should not have impurities.
Composite bearing allows running noise slightly in the work, 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 composite bearing clean fragrance.
Bearing in the horizontal plane and vertical plane junction with fine chamfering, and has a dark side.
SKF bearing in the process of normal use, installation of bearing parts allowed to have a certain temperature, when the hand touch body shell, should not feel hot as normal.
If rolling bearing using process temperature is too high, it can consider 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.
SKF bearing noise can be caused by many reasons, one is the bearing inner and outer surface wear.
Again, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise.
Keep the composite bearing and lubrication clean is very important.
Need before checking surface cleaning machine, and then remove the perimeter of the bearing parts.
Oil seal is very fragile parts, so need to carefully remove, not excessive force, and then carefully check oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace, and bad seal will cause the damage of SKF bearing and severe equipment downtime.
