FAG forklift bearing the normal use of the key operation maintenance problems

Dynamic operation, from the beginning of no-load speed, slowly progress to the rated operating conditions. Test run to check the items, whether there is abnormal sound, FAG bearing temperature changes, or disclose or discoloration of lubricant, and so on. Assumption of abnormal, should immediately stop, check machine, when it is necessary to remove the bearing inspection. Forklift bearing installed after the end of, in order to check the installed correctly, check to suspend operation. Small mechanical can rotate with the hand, to confirm whether it can rotate smoothly. Check project for a foreign body, scars, indentation, constitute the seized up, due to the bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction and provoked torque is too large, 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, for vibration, noise, rotating parts can have contact and so on, confirmed after no abnormalities, into power operation. 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 housing, poor precision, FAG bearing damage, foreign body intrusion, etc. Large ball bearings, grease lubrication, in particular environmental conditions, such as, low temperature in winter, there will be a roll-off sound problem. Ordinary, even if the attack roll-off sound, the temperature of the bearing will not rise, will not affect the fatigue life, life, grease can be normal use. Forklift bearing temperature, average according to the external temperature of the bearing. But the application of oil hole directly measure the temperature of the bearing outer ring more accurate. Bearing temperature, from the beginning of operation, usually 1 ~ 2 hours after the temperature stability. Assume that bad forklift bearing installation, the temperature will rise sharply, abnormal high temperature. For reasons such as lubricant, FAG bearing clearance is too small, too much bad installation, sealing device too much friction, etc. High-speed rotation, the choice of the ways of bearing structure, the lubrication error, etc. As well as the reason. Fat smooth method is simple, easy to roll change bento features, application is very common. Should be based on the rolling mill bearing operating temperature, rotational speed, rolling force and seal waterproof performance, impact vibration state such as size, for fat to choose suitable smooth and fat. To use high temperature resistant, strong viscosity, good extreme pressure performance and water resistance of high normal manufacturer of smooth and fat. According to the working characteristic of rolling mill bearing should choose EP additives in 2 #, 3 #, lithium base grease or polyurea grease. Although high-performance smooth fat procurement capital high, but less dosage, forklift bearing long life, the overall comprehensive capital is reduced. Other smooth grease filling amount must be moderate and fill in place, different type of fat can not mix, smooth rolling mill has been on the oil film bearing work appearance to normal state. Smooth filling grease for the first time the FAG bearing internal space can be filled, the vertical roll or diagonal roll in each bearing seat cover up and down to fill the smooth enough fat. Check the smooth after each roll change fat can turn black, can be impurity pollution, whether oxidation emulsification. If presents the above situation should be changed thoroughly smooth fat and check the seal and seal structure changed or modified in time; If the condition is good may continue to use after added new fat. Smooth of oil and gas bearing is an ideal way of smooth, bearing in the work of every once in a while tightening with smooth oil droplets into the air bearings inside, smooth oil on forklift bearing internal, air bearing heat away from the work, and at the same time to prevent external impurities water vapor in FAG bearings inside. Oil has not been atomized will not pollute the environment.
