Daily Maintenance Of Fag Sliding Bearing

Fag Sliding Bearing

1、 Problems in bearing maintenance technology:

The two complex problems related to fag bearing maintenance technology are: 1. When to change the oil. 2. How much oil should I change. If the oil change is too little, the sliding bearing will be scrapped in advance; If the oil is changed too much, the bearing will be in trouble or endanger the power coil and winding for a long time.

2、 Bearing maintenance technology:

The way to decide when to lubricate and when to stop oiling is very simple: make a baseline, make an Fag Sliding Bearing observation schedule and monitor when oiling.

1. Develop a baseline

The bearing foundation line reflects the DB strength under the condition of normal operation, no visual error and sufficient lubrication.

There are three ways to formulate the foundation line:

1) Comparison method: if there are multiple bearings of the same type, these sliding bearings can be Fag Sliding Bearing compared together. Observe each bearing with the same test method or from the same angle.

Analyze decibel intensity and sound quality. If there is no essential difference (less than 8 dB), we can set it as the basic DB strength of each bearing.

2) Set the basic line when adding lubricating oil: when adding Fag Sliding Bearing lubricating oil, listen to the sound intensity. When the sound intensity decreases and then increases. At this time, do not add too much lubricating oil, and set it as the base line.

3) Historical records:

observe the decibel strength of fag bearing, record it every day, and Fag Sliding Bearing then compare the record results of 30 days. If the decibel intensity changes little or no (less than 8 dB), we can set this as the base line and use it for the comparison of future observations.

2. Set observation schedule

For example, the criticality of equipment related to total output, environmental results and operation results is the main factor for Fag Sliding Bearing selecting, setting and evaluating mechanical systems. When the basic observation line is formulated, it is very necessary to test once a month.

For those high decibel bearings to be lubricated, the frequency of detection should be more frequent, so that the possible changes can be observed. If a bearing is in a state of being destroyed, the lubricating Fag Sliding Bearing oil can only temporarily cover up the error. However, the decibel intensity will soon rise to indicate the existence of errors.

In some cases, this phenomenon will appear in a few minutes, while in others, it will take a few days.

3. Inspection during lubrication

If the decibel of a fag bearing exceeds 8 decibels of the base line, we think the sliding bearing needs lubrication. When we realize that this bearing needs lubrication, knowing when to stop oiling will Fag Sliding Bearing prevent over lubrication. This can be done in the following three steps:

1) Calculate the consumption based on the guidance of the bearing manufacturer, and then inject lubricating oil without too much. This step is very subjective and has nothing to do with ultrasound, and this step has never failed.

2) When lubricating oil is injected, Fag Sliding Bearing the lubricating technician shall use ultrasonic instrument to detect the sliding bearing. Fill oil slowly until the decibel strength drops to the base line.

3) If there is no basic line as a guide, the amount of lubricating oil should stop when the sound decreases and then rises. At this time, the technician should stop using lubricating oil.

4. Ultrasonic bearing inspection

Ultrasonic inspection or monitoring is a reliable way to detect the initial (initial) stage of bearing damage. When the temperature rises or the intensity of low-frequency vibration increases, the ultrasonic warning will sound first.

When the sliding bearing is Fag Sliding Bearing damaged due to excessive use, it is very useful to use this method to inspect the bearing when there is a lack of lubricating oil or an excessive amount of lubricating oil.

5. Detect signs of failure

Ball bearings, like the metal on the track, such as rollers or ball bearings, will deform slightly when they begin to be overused. This will produce irregular surfaces, resulting in an increase in the emitted ultrasonic waves.

The change in amplitude obtained from the initial readings indicates one or two conditions: premature failure or lack of lubricating oil and initial sliding bearing failure. If the ultrasonic wave exceeds 8 dB of the base line, it will be accompanied by continuous impact noise, which indicates the failure of lubricating oil (dry fag bearing surface).

If the ultrasonic reading exceeds the expected reading and reaches 12 dB, there will be collapse noise, which can be assumed that the bearing has begun to enter failure mode.
