The effects of vibration on FAG bearings.
In casual use, shock is very sensitive to the FAG bearing failures, indentation, rust, cracks, spalling, wear will be reflected in the FAG bearing vibration measurement. So, by using a special measuring bearing vibration (frequency Analyzer, etc) can measure the size of the vibration, through frequency cannot be inferred from specific situations of exception. Measured value due to conditions of use of FAG bearings or sensor installation locations vary, therefore require prior to analysis and comparison of measurement values of each machine are determined benchmarks.
Second, the effect of temperature on FAG bearings.
Frequently expressed FAG bearings in high temperature anomalies. High temperatures may also be harmful to the bearing lubricant. FAG bearings to overheat sometimes can be attributed to the bearing lubricant. FAG bearings in more than 125 ° c temperature of the long and continuous transfer reduced bearing service life. Cause of the high temperature FAG bearings include: insufficient lubrication or excessive lubrication, lubricant. Contains impurities, excessive load, FAG bearings damaged rings, insufficient clearances, and oil have high friction and so on.
In the course of the use of FAG bearings are prone to elevated temperatures. When the bearing temperature rise, first determine whether the mistake, as did rise, should be dealt with as follows:
1. check the cooling water pressure, flow and pipe systems are normal. If low water pressure may be filter clogged, not processed in a timely manner, can shut down, when the confirmation work, again put into use.
2. Governor oil pressure should be checked, if oil pressure may lead to cooling water hydraulic valve is closed.
3. check for abnormal noise FAG bearings, and swing of FAG bearings has exception is detected.
4. take the oil sample observation of oil color is changing, and for tests to see if spoilage. If confirmed when the deterioration, downtime should be replaced with new oil.
5. check oil oil level is normal, if normal, check whether the tank Vent valve close. If you have secure, should oil supplement, if it is a sealant gasket oil leakage should stop processing.
Vibration damage to the FAG bearings can be said to be quite sensitive to indentation, rust, cracks, spalling, wear will be reflected in the FAG bearing vibration measurement. Therefore, through the use of a special FAG bearing vibration Measurer (frequency Analyzer, etc) can measure the size of the vibration, through frequency cannot be inferred from specific situations of exception. Measured value due to conditions of use of FAG bearings or sensor installation locations vary, therefore require prior to analysis and comparison of measurement values of each machine are determined benchmarks.
We then look at the effect of temperature on the bearing, frequently expressed FAG bearings in high temperature anomalies. High temperatures may also be harmful to the bearing lubricant. FAG bearings to overheat sometimes can be attributed to the bearing lubricant. FAG in more than 125 ℃ temperature long-term continuous transfers reduce bearing life. Cause of the high temperature FAG bearings include: insufficient lubrication or excessive lubrication, lubricant. Contains impurities, excessive load, FAG bearings damaged rings, insufficient clearances, and oil have high friction and so on.
Therefore continuity FAG bearing temperature monitoring is necessary, whether measured FAG bearing itself or other important parts. If operating conditions do not change case, any temperature changes may have occurred at fault.
FAG bearings periodic measurement of temperature using a thermometer, such as digital thermometers for precision measuring and bearing temperature degrees centigrade or Fahrenheit units display. The importance of FAG bearings, mean when it is corrupted and may cause the device to stop, so this kind of FAG bearings should preferably be retro-fitting of temperature probes.
