FAG bearing of daily maintenance and the latest way to care

One, bearing the maintenance of the technical problems are as follows: the FAG bearing maintenance technology of two complex the problem is: 1, what time to replace oil. 2, should put on a few oil. If an oil change is too little, sliding bearing will be scrapped earlier; If oil change too much, bearing will fall into a dilemma or long-term harm power coil and roll line. Bearing maintenance technology: smooth and in what time resolution to suspend the oil way is simple: to develop a life line, work out plans to examine table and filling time stop monitoring. Line 1, line set a foundation bearing foundation is reflected in normal operation, no apparent mistake, enough db strength under the condition of smooth. Make life line three ways: 1) , compare law: if there are more than the same type of bearing, the sliding bearing can be in together. In the same way to or from the perspective of the same tests to examine each bearing. Analyze the decibel strength and sound quality. If there were no substantial difference ( Less than 8 decibels) , we can set it for each bearing strength of the warp and woof of db. 2) Oil, add smooth line: time setting foundation when smooth add oil, listen to sounds, when the intensity of the sound to land and then rise. At this time, don't add too much oil, smooth lines and set it as a foundation. 3) , history: see FAG bearing strength of decibels and record every day, and then compare with 30 days to record the results. If the db intensity changes very little or no change ( Less than 8 decibels) , we are able to set the line for the foundation, and is used to view results match the value in the future. 2, set the time table, such as, environment, operating results and production related equipment of the key is to choose and set up key elements of evaluation of mechanical system. One month after the root view line set, test time, it is very necessary. About high decibel bearing, who have to smooth should detect the frequency of more frequent, so you can see that it changes the possible attack. If a bearing is in a state will damage, so smooth oil can only temporarily cover a mistake. However, db intensity will soon rise to manifest error exists. Under certain conditions, this kind of phenomenon will emerge in a few minutes, some needs a few days. 3, and smooth when testing if a FAG bearing grounded in db beyond line 8 decibels, we thought the smooth sliding bearing requirements. When we realize the smooth bearing demand, you know what time to suspend the oil will avoid excessive smooth rendering. Can accomplish in accordance with the following three steps: 1) Calculation, bearing the guidance of the consumer as the foundation dosage, and then injected into smooth oil, not too much. This step is very objective, has nothing to do with ultrasonic, and this step never fail. 2) , when injected into smooth oil smooth technicians used ultrasonic instrument detection of sliding bearing. Gradually filling until db intensity to a life line. 3) Line as a guide, if do not have a foundation, the dosage of the smooth oil should be suspended when voice down and then rise. At this moment, the technician should continue to use smooth oil. 4, ultrasonic bearing inspection ultrasonic inspection or surveillance is aware of early damage of bearing ( The beginning) The most secure way. When the temperature or low frequency vibration strength enhancement, ultrasonic, warned would be the first ring. Early when sliding bearing damage due to use of excessive, the shortage of oil or smooth smooth a glut of oil, using this way to inspect bearing is very useful. 5, and detect the signal of failure like metal on the tracks of ball bearings, such as roller or ball bearings beginning overused, small deformation would attack. This kind of condition can produce irregular appearance, thus cause distribution of ultrasonic wave increased. From the early reading changes indicate the amplitude of the one or two kind of situations: early early failure or smooth oil shortage and sliding bearing failure. If ultrasonic beyond toes in line 8 decibels, will have a lasting impact, along with the noise, the noise indicate smooth oil failure ( Boring FAG bearing appearance) 。 If beyond the expected reading ultrasonic, arrived at 12 db, there will be a collapse of the noise, the noise for the bearing can be assumed to have start form into failure.
