Technician as an FAG bearings must want the most is the FAG bearing on the present equipment and how to be more good running and and increase their service life of. Indeed, this is the place must be a maximum effort, while the relationship between a bearing is good or bad is subject to a number of habits, so we need a good grasp of the habits, FAG bearings run unimpeded.
One, bearing the maintenance of technical problems:
The FAG bearings maintenance techniques the two complex issues: when oil. How much oil. If the oil is too little, plain bearings will be early retirement; if the oil too much, the bearings will fall into difficulties or long-term damage to the power coil and reel.
Two, bearing maintenance technology:
Decide when lubrication as well as when to stop oiling is very simple: to develop a baseline to develop the monitor when the observation schedule and oiling.
To develop a baseline
FAG Bearings baseline reflects no visible error during normal operation, the decibel intensity sufficient lubrication conditions.
To establish the baseline of three ways:
1) Comparative Law: If the same type of bearings, sliding bearing can be compared together. Using the same test method or from the same angle to look at each bearing. Analysis of the intensity in decibels and sound quality. If there is no essential difference (less than 8 dB), we can set it to each one bearing the basis of decibel intensity.
2) Add oil when setting the base line: When the lubricant is added, listening to the sound intensity and sound intensity decreased and then increased. At this time, do not add too much oil, and set it as the baseline.
3) History: To observe the FAG bearings dB intensity, daily record, and then record the results of comparison of 30 days. If the decibel intensity change little or no change (less than 8 dB), we can put this set to the baseline, and for later comparison value of the observed results.
2, set up observation schedules
Such as gross domestic product, environmental results, the operating results related to the device key is to choose and set up the assessment of mechanical systems. When the basis of observed line after the enactment of the month detection time is necessary. To lubricate high-decibel bearings should be the frequency of detection is more frequent, so you can observe its possible changes. If a bearing is to be destroyed by the state, then the oil can only temporarily mask the error. However, the db strength will soon be increased to show the error exists. In some cases, this phenomenon within a few minutes will be apparent, while others take a few days.
3, lubrication detected
If the decibel level of an FAG bearings over baseline 8 db, we believe that this plain bearings requiring lubrication. When we realized that the bearings need lubrication, then know when to stop oiling will prevent over-lubrication. Follow these three steps to complete:
1) the guidance of FAG bearings manufacturer's calculated on the basis of usage, and then injected into the lubricating oil, not too much. This step is very subjective, and has nothing to do with the ultrasound, and this step is never failure.
2) When injecting grease lubrication technician using ultrasonic detection equipment bearings. Slowly oiling until the decibel intensity dropped to baseline.
3) If there is no baseline as a guide, the amount of the lubricant should be in the voice dropped and then rose to stop. At this time, the technician should cease to continue to use lubricants.
4, the ultrasonic bearing inspection
Ultrasonic inspection or monitoring is found FAG bearings damaged early (the beginning) the most reliable way. When the temperature or low frequency vibration intensity strengthen, ultrasonic warning will be the first ring. When the sliding bearing due to the use of excessive damage to the early lack of excess lubricating oil or lubricating oil, bearing such inspections is very useful.
5 found that the failure signal
Like a metal ball bearing track, such as roller or ball bearings, excessive use occurs slightly deformed. This situation will produce irregular surface, resulting in the dissemination of ultrasound to increase. The amplitude of the change from the initial reading that one to two conditions: early failure or lack of lubrication and initial sliding bearing failure. If the ultrasound is more than eight db baseline, accompanied by the continued impact of noise, this noise that lubricant failure (dry FAG bearing surface). If the ultrasound readings more than expected readings, 12 db is reached, there will be a collapse of the noise, this noise can be assumed to have begun to enter a failure mode for the FAG bearings.
