TIMKEN cylindrical roller bearing temperature is too high caused by the analysis of the causes of failure

TIMKEN bearing temperature, generally have a bearing on the surface of the outdoor temperature can be predicted, if using the oil hole can directly measure temperature of cylindrical roller bearing outer ring, is more appropriate. Generally, the temperature of the bearings with bearing operation began to slowly rise, 1 - After 2 hours to reach steady state. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Using thermal device can monitor the working temperature of cylindrical roller bearing, and implement e. automatic alarm when the temperature exceeds or stop to prevent the shaft accidents. With high temperature often said cylindrical roller bearing is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes overheated bearings can be classified to the bearing lubricant. If the cylindrical roller bearing in more than 125 ℃ temperature for a long time even move to reduce the bearing life. The causes of high temperature roller 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 continuous monitoring of the cylindrical roller bearing temperature is necessary, cylindrical roller bearing whether measured bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. First of all, reasonable structure design and equipped with advanced, just can have a long bearing life. Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of finished products bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing. TIMKEN cylindrical roller bearing materials of metallurgical quality were the main factors influencing the premature failure of the rolling bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still one of the main influence factors of bearing failure. Select material adequacy is still bearing failure analysis factors must be considered. TIMKEN cylindrical roller bearing, the main task of the failure analysis is based on a lot of background material, analyze data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the bearing of the sudden.
