Before checks are required before cleaning the machine surface and perimeter of the TIMKEN bearings removal parts. Oil seal is very fragile parts, therefore need to be carefully demolished, not excessive force, and then carefully check the oil seal and its surrounding parts, if you have rendered out when adverse symptoms, be sure to replace out, bad oil seals will cause damage to the bearings and equipment downtime. TIMKEN bearings after the installation is complete, in order to check for proper installation, run checks to. Small mechanical hand rotation, to confirm that the rotate smoothly. Check the project due to foreign body, caused by scars, indentation to seize up, because of the bad installation, mounting process arising out of the bad moments are not stable, owing to the clearance is too small, caused by installation errors, seal friction torque is too large, and so on. Without exception you can start power function. Large machinery cannot be rotated manually, so no load starting immediately after cutting off power, mechanical idle, check for vibrations, noise, contact rotating parts, and so on, after you confirm without exception, into the dynamic operation. Dynamic operation, starting from no-load speed, slowly raised to the conditions set forth in the rated operation. Things to check for in the commissioning, whether any unusual changes in sound, TIMKEN bearings temperature, lubricant leakage or discoloration, and so on. If you find an exception, should immediately suspend the operation, inspection machinery and, if necessary, to remove the bearings checked.
Bearings temperature, generally according to the external temperature of the bearings seat to speculate. Uses of oil hole direct measurement of the temperature of the bearings outer ring is more accurate. Bearings temperature, from a running start rising, usually temperature-stable after 1-2 hours. Bad if the bearings are mounted, the temperature rises dramatically, exception occurred at high temperature. The reason such as excessive lubricant, bearings clearance is too small, poor installation, sealing device too much friction. Occasions of high speed rotation, selection of bearings structures, lubrication is also the cause of the error. TIMKEN bearings turn tone with checks such as stethoscopes, TIMKEN bearings appeared strong metal tone, abnormal, irregular, including abnormal sound abnormal sound. Due to poor lubrication, shaft or housing poor accuracy, bearings damage, intrusion of foreign bodies, and so on. When you check the bearings, don't let bearings contaminants or moisture-exposed environment. If the work is broken, should be oiled paper plastic or similar material of his machine. If not demolition may check the case clean no masking of bearings, to the coating with brush to wash oil solvent (white spirit) cleaning, use a lint free cloth wipe again compressed air dry or blow dry (be careful not to allow the bearings components starting rotation). Could not be cleaned and sealed bearings with cover or dust; just wipe the external surface. If the bearings is damaged when replacing on demand. In the scheduled maintenance periods of downtime than replace the TIMKEN bearings due to a corrupt array selected into the sudden loss of downtime a lot more economic
