Under normal circumstances, the flange bearing lubrication and lubrication in or after the natural temperature rises and the last one to two days. The stability and performance of the vibration flange bearing is very sensitive to the KOYO bearings damage, such as peeling, indentation, rust, crack, wear will be reflected in the measurement of vibration, so, through the use of flange bearing vibration measurer special (frequency analyzer etc) can be measured by the size of the vibration, the frequency is not can be inferred from abnormal situation. The measured values for different operating conditions or sensor installation location, therefore require prior to each machine measurement comparison criteria.
Flange bearing temperature, generally outside of room temperature can be speculated that, if the use of the oil hole can directly measure the temperature of the bearing outer ring of KOYO, is more suitable for the.
Usually, the temperature with flange bearing running slowly rising, reach a steady state after 1-2 hours. The normal temperature of flange bearing due to the heat capacity, the heat dissipation, speed and load and different. If the lubrication, install suitable, flange bearing temperature quick rise, abnormal high temperature, then we must stop, take the necessary preventive measures.
The use of thermal sensor can always monitor the bearing temperature, and the temperature exceeds the set value automatically alarm or stop to prevent burning temperature often bearings in unusual circumstances. High temperatures may also be harmful to the flange bearing lubricant. Sometimes overheated bearings can be attributed to KOYO bearing lubricant. If the bearings at the temperature higher than 125 DEG C long-term even would reduce bearing life. Including the reason of the high temperature in Qingdao: flange bearing caused by insufficient or excessive lubrication lubrication, lubricant. Contains impurities, the load is too large, the flange bearing damage, lack of space, and oil have high friction and so on.
Regular volume flange bearing temperature can be measured by the aid of the thermometer digital thermometer, for example, can be accurately measured flange bearing temperature according to C or Fahrenheit temperature display unit. The importance of the bearing, means when it is damaged, will cause the equipment downtime, which preferably should be equipped with a temperature detector.
(1), keep the bearings and the surrounding clean. Even if it is invisible to the eye small dust, will bring bad effect to the KOYO bearings. So, to keep the surrounding clean, so that dust is not into the bearing.
(2) use, circumspect. And bearing a strong impact in use, will have scars and indentation, became the cause of the accident. In severe cases, will crack, fracture, so we must pay attention to.
(3), using the right tools. Avoid to replace the existing tools, you must use the appropriate tool.
(4), attention should be paid to the flange bearing corrosion. When operating the KOYO bearings, hand Khan will become the cause of rust. To note that the clean hands operation, the best to wear gloves.
