The Influence Of Temperature And Vibration On SKF Bearings

　　1. The impact of vibration on SKF bearings.

　　In normal use, vibration is very sensitive to bearing damage, peeling, indentation, rust, cracks, wear, etc. will be reflected in the bearing vibration measurement. Therefore, by using a special bearing vibration measuring device (frequency analyzer, etc.), the magnitude of the vibration can be measured, and the specific abnormality cannot be inferred through the frequency division. The measured value is different due to the use condition of the bearing or the installation position of the sensor, so it is necessary to analyze and compare the measured value of each machine in advance to determine the judgment standard.

　　2. The influence of temperature on the bearing.

　　High temperature often indicates that SKF bearings are in abnormal conditions. High temperature is also harmful to the lubricant of the bearing. Sometimes bearing overheating can be attributed to the lubricant of the bearing. Long-term continuous rotation of bearings at temperatures exceeding 125°C will reduce bearing life. Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants. Containing impurities, excessive load, bearing ring damage, insufficient clearance, and high friction caused by oil seals, etc.

　　In the process of using SKF bearings, it is prone to temperature rise. When the bearing temperature rises, first judge whether it is misoperation. If it does rise, the following treatments should be done:

　　1. Check whether the cooling water pressure, water flow and piping system are normal. If the water pressure is low, it may be that the filter is clogged. When it cannot be processed in time, it can be stopped for processing. When it is confirmed that it can work, it can be put into use.

　　2. Check the oil pressure of the governor. If the oil pressure is low, the cooling water hydraulic valve may close.

　　3. Check whether the SKF bearing has abnormal noise, and check whether the bearing swing is abnormal.

　　4. Take an oil sample to observe whether the oil color has changed, and conduct a laboratory test to see if it has deteriorated. If the deterioration is confirmed, stop the machine and replace with new oil.

　　5. Check whether the oil level is normal. If it is abnormal, check whether the oil tank drain valve is tightly closed. If it is closed tightly, oil should be refilled; if the sealing rubber gasket is leaking oil, it should be shut down for processing.
