The temperature of the SKF bearing; generally the temperature outside the bearing can be estimated; if the oil hole can directly measure the bearing outer ring temperature; it is more suitable. Today I will analyze the small common sense about SKF bearing temperature. .
Generally; the temperature of the SKF bearing gradually rises with the start of the bearing; the steady temperature is reached after 1-2 hours. The normal temperature of the SKF bearing is due to the heat capacity of the machine; the heat dissipation; the speed and load are different. If it is smooth, the device is suitable; The bearing temperature will rise sharply; abnormal high temperature will occur; it is necessary to stop the work; take necessary precautions. Use the thermal sensor to monitor the working temperature of the SKF bearing at any time; and when the temperature exceeds the specified value, actively alarm or stop burning. Axis incident.
The high temperature often indicates that the SKF bearing is in an abnormal condition. The high temperature is also harmful to the smoothing agent of the SKF bearing. Sometimes the bearing overheating can be attributed to the smoothing agent of the bearing. If the bearing rotates for more than 125 °C for a long time, the bearing life will decrease. .
Causes of high temperature bearings lead to high temperature bearing causes: smooth lack or overheating smooth; smoothing agent. Contains impurities; excessive load; bearing loss ring; lack of clearance; and high friction of oil seal attack and so on.
Therefore, it is necessary to continuously monitor the bearing temperature; whether it is measuring the bearing itself or other important parts. If it is in the same working conditions; any temperature change can indicate that the problem has occurred.
The timing measurement of SKF bearing temperature can be measured by means of a thermometer; for example, SKF bearing digital thermometer; the bearing temperature can be accurately measured and displayed according to °C or Fahrenheit temperature.
Importance of SKF bearings; meaning that when it is damaged; it will form a stop of the equipment; therefore, the most suitable type of such a bearing should be equipped with a temperature detector.
Under normal conditions; SKF bearings will have a natural temperature rise just after smoothing or smoothing and continue for one or two days.
