Need before checking surface cleaning machine, and then remove the KOYO bearing the perimeter of the 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 the bad oil seal will cause the damage of the bearing and severe equipment downtime.
Bearings after installation, in order to check whether installed correctly, check for running.
Small mechanical can rotate with the hand, to confirm whether to rotate smoothly.
Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on.
If there is no abnormal can start power operation.
Large machinery from manual rotation, so after no-load start immediately cut off the power, machine idle, check whether there is presence of vibration, noise, rotating parts contact, etc. , confirmed after no abnormalities, into power operation.
Dynamic operation, from the beginning of the no-load speed, slowly up to the rated operating conditions.
Test run to check the items, whether there is abnormal sound, KOYO bearing temperature, lubricant leakage or discoloration, and so on.
If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the bearing inspection.
Bearing temperature, average according to the external temperature of the bearing.
But using the oil hole directly measuring the temperature of the bearing outer ring more accurate.
The bearing temperature, starting operation gradually increases, usually 1 ~ 2 hours after the temperature stability.
If the bearing installation, the temperature will rise sharply, abnormal high temperature.
The reason such as lubricant, bearing clearance is too small, too much bad installation, excessive friction sealing device, etc.
High-speed rotation, the choice of the ways of bearing structure, the lubrication error and so on is also the reason.
KOYO bearing examination such as the rotation of the sound with a stethoscope, a strong metal noise, such as vision, irregular note that exception.
Its reason has poor lubrication, shaft or precision bearing, bearing damage, foreign body intrusion, etc.
Check the bearing, don't let bearing exposure to pollutants or moisture environment.
If the job is interrupted, should with oil film, paper or similar material by machine.
If don't have to remove and may perform inspection of cleaning without masking of bearing, to coating with brush with petroleum solvent (
白酒)
Cleaning and dry with a lint-free cloth or with compressed air to blow dry,
Be careful not to let the bearing component starting rotation)
。
Do not clean the encrypted block or dust bearing;
You just wipe the outer surface.
If the bearing is need to replace damaged situation.
In regular maintenance downtime period change than the array bearing KOYO bearing damage selected into a sudden shutdown loss much more economical
