IKO self-aligning roller bearings after installation need to turn the check method of attention

IKO self-aligning roller 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, the change of temperature, lubricant leakage or discoloration, and so on. If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the IKO spherical roller bearing. Temperature according to the external temperature of the bearing. But using the oil hole directly measuring the temperature of the outer ring is more accurate. Starting operation increased, usually 1 ~ 2 hours after the temperature stability. If the installation, the temperature will rise sharply, abnormal high temperature. The reason such as lubricant, clearance is too small, too much bad installation, sealing device too much friction, etc. High-speed rotating occasions, such as the choice of structure, the lubrication method error is also the reason. The examination such as rotation 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.
