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 bearing 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 TIMKEN bearings checked.
TIMKEN bearing temperature, generally according to the external temperature of the bearing seat to speculate. Uses of oil hole direct measurement of the temperature of the bearing outer ring is more accurate. TIMKEN bearing 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. Too many reasons such as lubricants, TIMKEN bearing clearance is too small, poor installation, sealing device too much friction. High speed rotation occasions, TIMKEN bearings, lubrication method choice is also the cause of the error.
TIMKEN bearings turn tone with a stethoscope to check, there is a strong metal noises, different sound irregular sound of note exceptions, such as. Its poor accuracy due to poor lubrication, bearings, TIMKEN bearing damage, such as intrusion of foreign bodies
