In the mechanical operation of the process, the maintenance of the SKF bearing, repair, to ensure reliability of its operation, improve productivity. How to correct installation and operation of SKF bearing, and let its maximum effect and service life, next, technician Delik Qingdao Bearing Co. Ltd will provide you the simple explanation of SKF bearings use common sense and the daily repair and maintenance matters needing attention.
1.SKF bearing cleaning: often use gasoline, kerosene as a general cleaning agent. SKF bearing repair disassembled, first recorded appearance of the bearings, confirmation, began a wash bearing residual lubricant, lubricating oil sample amount. Coarse, fine cleaning, cleaning, respectively in the container, put the metal bottom net, dirt so the outer spherical bearing no direct contact with the container.
Vibration of 2.SKF bearings: bearing vibration is sensitive to SKF bearing damage, such as peeling, indentation, rust, crack, wear will be reflected in the measurement of bearing vibration, so, through the use of special bearing vibration measuring device ( frequency analyzer etc) can measure the size of dynamic vibration, through frequency cannot be inferred from abnormal situation. The measured values for different outer spherical bearing conditions of use or sensor installation location, therefore require prior to each machine measurement comparison criteria.
3.SKF bearing temperature: the temperature of the bearing, general bearing outside of room temperature can be speculated that, if the uses of oil hole can directly measure the temperature spherical bearing outer ring, the more appropriate.
Usually, the SKF temperature of the bearing with the bearing running slowly rising, reach a steady state after 1-2 hours. The normal temperature of the bearing for machine heat capacity, heat capacity, speed and load and different. If the lubrication, install appropriate, bearing temperature quick rise, abnormal high temperature, then we must stop, take the necessary preventive measures.
The use of thermal sensor can outer spherical bearing operating temperature monitoring at any time, and realize temperature exceeds the set value automatically alarm or stop to prevent burning shaft accident.
4.SKF bearing repair and judgment: to determine if the bearing is removed, can be used to check the clearance of bearing.
Maintenance includes: monitoring working conditions, supplement and replacement of the lubricant, regular demolition inspection, it is best to keep the machine operation standard regular appropriate working conditions,. Maintenance operation, a rotary sound, vibration, temperature, lubrication condition, the spherical bearing and other separation-shaped bearings problem, you can scroll through the body, the outer ring raceway surface were examined.
Check the raceway, raceway, cage worn surface, the spherical bearing clearance increases, and decreases the accuracy of unusual size without damage. Non separation SKF ball bearing inner ring, a support level, rotate the outer ring to confirm.
