Temperature of KOYO cylindrical roller bearing vibration cause analysis of the troubleshooting

In KOYO bearing in use process, the influence of vibration and temperature of cylindrical roller bearing is very big, let's take a look at the influence of the vibration of the bearing of KOYO bearing. Vibration of the bearing damage is quite sensitive, peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measuring. So, through the use of special cylindrical roller bearing vibration measuring device ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values of 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 then look at the influence of temperature on the bearing. With high temperature often said bearing is in abnormal situation. High temperature is also harmful to KOYO bearing lubricant. Sometimes overheated bearings can be classified to the bearing lubricant. If the bearing temperature for a long time even the transfer of more than 125 ℃ lower bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, bearing damage, clearance, high friction and oil seal and so on. So the continuity of bearing temperature monitoring is necessary, whether it is measuring cylindrical roller bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. Regular bearing temperature measurement by using a thermometer, digital thermometer, for example, can accurate bearing temperature measurement and display by ℃ or Fahrenheit units. The importance of bearing, means that when the damage cause of equipment downtime, so this type of bearings shall be equipped with best temperature probe. For as long as possible in good condition to maintain original state, KOYO bearing arrangement needed maintenance overhaul in order to prevent accident, to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis. ( 1) Running state overhaul of KOYO bearing rotation for the maintenance of sound, vibration, temperature and lubricant condition on the properties of maintenance, judgment, supplement or replacement period of lubricant. ( 2) KOYO bearing maintenance in making preventive maintenance and replacement of mechanical, fully to take out the bearing observation, of rail surface conditions and presence of lesions, can use to confirm again. Turning the sound of overhaul project includes bearing in operation, vibration, temperature, the condition of the lubricant, etc. ( 1) KOYO bearing of rotary sound clinical hydrophone is used to survey the size of the noise and sound quality. Even if a handful of cylindrical roller bearing in the condition of fatigue spalling anomalies and irregular, if proficiency is also possible to listen to. The typical abnormal sound like page (shown in 2) KOYO bearing vibration using the bearing vibration generator, quantitative analysis of the vibration amplitude, frequency, etc. , thus infer bearing damage condition. But due to different bearing conditions of use and the determination of location, it is necessary to use mechanical measurements, decided to determine the benchmark. ( 3) KOYO bearing temperature of bearing temperature after operation began to slowly rise, usually for a period of time after the saturated state. Constant temperature of the bearing due to mechanical heat capacity, heat quantity, speed and load. Bearing temperature before the saturation state and abnormal rises, consider the following pages is shown in reason, stop and take the necessary measures. ( 4) Lubrication investigation of grease and lubricating oil in use for to understand the status of the bearing operation is effective. Of course from the moisture content, sundry, iron powder and so on to judge the grease or oil leakage, discoloration, and degradation. Believe that there is a lubricant leakage and iron powder, metal powder mixed with situations such as a foreign body, regularly for leakage, cylindrical roller bearings, such as temperature and vibration of quantitative observation, if think there are abnormal, early maintenance
