SKF bearings temperature, General bearing outside of room temperature can be speculated that, if the uses of oil hole can directly measure the temperature of bearing outer ring, it is more appropriate.
Usually, temperature of the bearings with bearing running slowly rising, 1-2 hours later to reach a steady state. The normal temperature of the bearing due to the heat capacity of the machine, heat dissipation, speed and load to another. If lubricated, install appropriate, bearing temperature quick rise, abnormal high temperature occurs, in which case you must stop, take the necessary preventive measures.
Use heat sensors can monitor SKF bearing temperature at any time, and alarm or stop automatically when the temperature exceeds the specified value prevents burning shaft accident.
High temperature often indicates that the bearing is in exceptions. High temperatures may also be harmful to the bearing lubricant. Sometimes bearing overheating can blame on the bearing lubricant. If SKF bearings in more than 125 ℃ temperature long-term continuous transfers reduce bearing life. Cause of the high temperature bearings include: insufficient lubrication or excessive lubrication, lubricant. Contains impurities, excessive load, bearing loss rings, insufficient clearances, and oil have high friction and so on.
Thus continuity is necessary to monitor bearing temperature, bearing either measurement or other important parts of the bearing itself. If operating conditions do not change case, any temperature changes may have occurred at fault.
SKF bearing periodic measurement of temperature using a thermometer, such as digital thermometers for precision measuring and bearing temperature degrees centigrade or Fahrenheit units display. Bearings of the importance to the effect that, when it is damaged, will cause the device to shut down, so this type of bearings should preferably install temperature scanners. Under normal circumstances, after in the lubrication of the bearing or lubrication will have natural temperatures rise and lasts 1-2 days.
Usually, the working temperature above 150 ° called high temperature bearings using SKF bearings, due to chromium bearing steel in use when the temperature exceeds 150 °, dramatic decline of its hardness, dimensional instability, bearing does not work properly. So for operating temperature 150 ° to 350 ° conditions of bearings, rings and rolling elements still use ordinary high-carbon chromium bearing steel, bearing components must be special tempering process, should generally be higher than the operating temperature tempering under 50 °. Bearing steels after tempering treatment according to these requirements, will work in temperatures under normal use. But due to the decline in hardness after tempering, reduced bearing service life.
Check and record work for SKF bearings in critical condition, the analysis of such information, you can identify problems, in the event of failure before the maintenance. So as to ensure the safety of bearings to use!
Here is routine maintenance checks on:
Check SKF bearing vibration values change, an abnormal noise, temperature, amount of lubricant and character changes, driven variation of the electrical currents, examination is normal, if there is an exception, it should be dealt with accordingly.
Here is the check the trend of project control.
1. determine the chart format of each checked item.
2. determine the inspection cycle.
3. determine the inspection method and inspection equipment needed. Check data is recorded. Observe the chart data changes.
If the data exceeds the standard control value, may be a sign of damage to the equipment. Confirm that the cause of the problem, for repairs when needed.
