When we use SKF bearings, if we find that the temperature is very high, we should stop the operation of the equipment quickly, find out the cause, and deal with it according to the solutions provided above. However, the solutions may be different due to the different causes of bearing heating, so we should treat it according to the specific situation and complete it with the help of technicians.
1. To check the temperature of SKF Bearing during rotation, it is more appropriate if the temperature of bearing outer ring can be measured directly by oil hole. In general, the temperature of the bearing can be inferred from the temperature outside the bearing chamber. If the lubrication and installation parts are appropriate, the bearing temperature will rise sharply and abnormal high temperature will occur. At this time, the operation must be stopped and necessary preventive measures must be taken.
2. Check the sound condition of the bearing during rolling. Even if the bearing has slight peeling and other damage, it will produce abnormal sound and irregular sound. Therefore, the sound detector can be used to distinguish. The sound detector is used to check the size and sound quality of the rolling sound of the bearing in operation, so as to prevent it in advance.
3. Check the vibration of SKF Bearing during operation. The peeling, indentation, corrosion, crack, wear, etc. will be reflected in the vibration measurement of the bearing. The bearing vibration is very sensitive to the damage of the bearing. Therefore, the vibration can be measured by using a special bearing vibration meter (frequency analyzer, etc.), and the specific abnormal situation can not be inferred by frequency division. Because the measured values are different due to the service conditions of the bearing or the installation position of the sensor, it is necessary to analyze and compare the measured values of each machine in advance to determine its judgment standard.
Generally, the temperature of the bearing rises slowly with the start of operation. The introduction and application of the bearing coating removal process will reach a stable state after 1-2 hours. The normal temperature of the bearing varies with the heat capacity, heat dissipation, speed and load of the machine.
Whether on the shaft or in the bearing seat, SKF Bearing is required to fix its position in radial, axial and tangent directions. Radial and tangential positioning is achieved by tight fit of bearing ring, but axial positioning only adopts tight fit in a few cases; Generally, axial limit parts, such as end caps and retaining rings, are used to limit the axial position within the clearance range.
