Under normal circumstances, flanged bearing relubrication after lubrication or just have natural temperatures and lasts 1-2 days. Stability of flange bearings and vibration are sensitive to damage of the bearings, such as indentation cracks, wear, corrosion, spalling, are reflected in the vibration measurements, therefore, through the use of special flange flange bearing vibration Measurer (frequency Analyzer, etc) measures the size of the vibration, through frequency not infer exceptions to the specific situation.
The values measured are different depending on conditions of use or the sensor installation location, and therefore require prior to each machine analysis and comparison of measurement values to be determined criteria.
Flanged bearing temperature, room temperature outside can gauge if using direct measurements of the oil hole flange bearing temperature, is more appropriate.
Typically, temperature slowly with the flange bearings running start to rise, 1-2 hours to stabilize. Normal flange bearing temperature heat capacity of machines, thermal output, speed and load another. If lubricated, install appropriate, bearing temperature is rising quite sharply, unusual high temperatures, must stop and take the necessary precautions.
Use heat detector to monitor bearing temperature over time and temperature alarm when exceeding a specified value or stop to prevent high-temperature-fired often indicates that the bearing is in an abnormal situation. High temperatures may also be harmful to the bearing lubricant. Sometimes overheated bearing could be attributed to the bearing lubricant. Bearing temperature in more than 125 ° c long-term continuous transfers reduce the bearing life. Including Qingdao flange bearing high temperature caused by: inadequate or excessive lubrication lubrication, lubricant. Contains impurities, excessive load, flange rings of bearing damage, inadequate clearance, and oil have high friction and so on.
Flanged bearing temperature measurement using a thermometer on a regular basis, such as digital thermometers for precision measurement of bearing temperature in Celsius or Fahrenheit temperature displays. The importance of bearing, means when it is damaged, will cause the device to shut down, so these are best fitted with temperature probe.
(1) carefully. In use and bearing a strong impact, scratch and indentation, as the cause of the accident. Serious cases, crack, break, so care must be taken.
(2) keep the bearings and the surrounding clean. Even eye can't see the small dust will also bring adverse effects to the bearing. So, you want to keep clean around, the dust does not invade the bearings.
(3) pay attention to bearing corrosion. Operation when flange bearings, Khan will become the cause of rust in his hands. Should pay attention to the clean hands operation, as possible with gloves on.
(4) using the appropriate tool. Avoid to substitute existing tools, you must use the appropriate tool.
