How to reduce the influence of temperature and vibration of NTN bearing - bearing knowledge

One, the influence of the vibration of NTN bearing. In the usual use of NTN bearing vibration damage is quite sensitive, peeling, indentation, rust, crack and wear will be reflected in the NTN bearing vibration measuring. So, through the use of special bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values for NTN bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. Second, the influence of temperature on NTN bearing. With high temperature often said NTN bearing is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes NTN bearing overheating can be classified to the bearing lubricant. If the NTN bearing in more than 125 ℃ temperature for a long time even move to reduce the bearing life. The causes of high temperature NTN bearing include lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, NTN bearing ring, clearance, high friction and oil seal and so on. In the process of using the NTN bearing is easy to appear the phenomenon of temperature rise. When the bearing temperature, first determines whether the wrong operation, such as really rise, should do the following processing: 1. Check the cooling water pressure, water flow and pipeline system is normal. If water is likely to be lower filter blockage, cannot be handled in a timely manner, to stop treatment, when confirm can work, then put into use. 2. Should be to check if the governor oil pressure, oil pressure is low can lead to cooling water hydraulic valve closed. 3. To check whether there is sound, NTN bearing and detection of NTN bearing place whether there is abnormal. 4. Take oil whether there is a change of color, sample observation and test to see whether metamorphism. If confirm the degradation new oil should be replaced downtime. 5. Check the oil standard oil level is normal, if abnormal, check that the sump oil discharge valve is shut. If the matter, should fill oil, if is the sealant mat permeability oil, should stop processing. Vibration of NTN bearing damage is quite sensitive, peeling, indentation, rust, crack and wear will be reflected in the NTN bearing vibration measuring. So, through the use of special NTN bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values for NTN bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. We went on to look at the influence of temperature on the bearing, using high temperature often said NTN bearing is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes NTN bearing overheating can be classified to the bearing lubricant. If NTN in more than 125 ℃ temperature for a long time even move to reduce the bearing life. The causes of high temperature NTN bearing include lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, NTN bearing ring, clearance, high friction and oil seal and so on. So the continuous monitoring NTN bearing temperature is necessary, whether measured NTN bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. NTN bearing temperature measured on a regular basis can use thermometer, digital thermometer, for example, can accurate bearing temperature measurement and display by ℃ or Fahrenheit units. The importance of NTN bearing, means that when the damage, can cause equipment downtime, so this type of NTN bearing should be equipped with best temperature probe.
