KOYO bearing inspection, the temperature, the use matters needing attention

1, 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. 2, bearing temperature, average according to the external temperature of the bearing. But using the oil hole directly measure temperature more accurately KOYO bearing outer ring. 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. Bearing the 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. 3, internal factor and the reason from the use of two ways bearing and the reason of the effect factors of using our method is reasonable, the use of intrinsic factor is when we choose to KOYO bearing level problem! ! Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. Installation conditions is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state run and early failure. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. In addition, analyze the grease and the surrounding medium, the atmosphere quality inspection is also very important. Keep the KOYO bearings and the surrounding environment clean even tiny dust invisible to the naked eye, will also bring bad influence to the bearing. So, keep the surrounding clean, make the dust will not invade the bearing. Carefully use. In use for bearing strong impact, will produce scar or indentation, induce accidents. Serious, will cause crack, fracture, must pay attention. Use the special tool of bearing. Must use a special tool, free replacement. Avoid bearing rust. Operating KOYO bearing, hand sweat can lead to rust. Pay attention to the operation, with clean hands gloves as far as possible, pay attention to corrosive gas.
