Effects of vibration and temperature on the bearing

Bearing during use, it can be said that vibration and temperature effects on the bearing is very large, we first look at effects of vibrations on the bearings of the bearing.
Vibrations on the bearings of the injury can be said to be quite sensitive to indentation, corrosion, cracking, spalling, and wear are reflected in bearing vibration measurement. Therefore, through the use of special measuring bearing vibration (frequency Analyzer) vibration size can be measured through frequency not infer exceptions in specific situations. Measured values for bearings, such as conditions of use or the sensor installation location differs, therefore require prior to analysis and comparison of measurement values of each machine are determined benchmarks.
We look at the effect of temperature on the bearing.
High temperature often indicates that the bearing is in unusual circumstances. High temperature but is also harmful to the bearing lubricant. Sometimes overheated bearings can retain the lubricant in the bearing. If the bearing temperature exceeds 125 ℃ long-term continuous transfers reduce the service life of the bearing. Causes of high temperature bearings including: inadequate or excessive lubrication lubrication, lubricant. Contains impurities, excessive load, ring of bearing damage, inadequate clearance, and oil have high friction and so on.
Monitor bearing temperature is necessary for continuity, whether measured or other important parts of the bearing itself. Under unchanged circumstances if it is in operation, any failure of the temperature change can be said to have occurred.
Bearing temperature measurement using a thermometer on a regular basis, such as SKF-digital thermometers for precision measurement of bearing temperature in degrees centigrade or Fahrenheit temperature displays. The importance of bearing to the effect that, when damaged, and will cause the device to shut down, these bearings should preferably be retro-fitting of the temperature probes.
