Bearing installed check the matters needing attention

Check the matters needing attention of bearings after installation, should guarantee the bearing installation, flexible rotation, no jam phenomenon, such as bearing improperly installed, can make the bearing temperature rise quickly and damage, even jammed bearing fracture and other major accidents. First of all, the rotation of the bearing is through listens, has a strong metal noise, abnormal sound, the sound of the irregular, etc. Because of poor lubrication, poor shaft or the bearing seat, bearing damage, foreign bodies, intrusion, etc. Second, bearing temperature, general according to the external temperature of the bearing. But using oil hole directly measuring the temperature of the bearing outer ring is more accurate. Bearing temperature from rising to normal operation, usually in a temperature stable ~ hours later. If not to install the bearing, the temperature will rise sharply, abnormal high temperature. The reason is that too much oil, bearing clearance is little, installation, sealing device too much friction, etc. High-speed rotation, the choice of the ways of bearing structure, the lubrication is also the cause of the error. Third, small mechanical can rotate rotate smoothly by hand. Check scars caused by foreign bodies in the engineering, the indentation is not normal, because of the bad installation, the installation process of torque is not stable, because of the gap is too small, large installation error, causes such as seal friction torque is too large. If there is no exception, the beginning of power operation. Fourth, heavy machinery can't manual rotation, so light and electricity mechanical idling immediately after beginning, for vibration, noise, rotating parts contact, etc. , confirmed after no abnormalities, into power operation.
