The normal temperature of the bearing varies with the heat capacity, heat dissipation, speed and load of the machine. Analysis of the cause of bearing damage indicates that about 40% of bearing damage is associated with poor lubrication. When the motor is working, the shaft can only be used as the temperature of the rotating bearing.

Analysis of the cause of bearing damage indicates that about 40% of bearing damage is associated with poor lubrication. When the motor is working, the shaft can only be used as the temperature of the temperature bearing of the rotating bearing. Generally, the temperature outside the bearing can be inferred. If the oil hole can directly measure the temperature of the bearing outer ring, it is more suitable.
SKF Group is the world's leading supplier of rolling bearings and seals. It appeared in Xuejiaya Village, Yongji County, Shanxi Province, from 221 to 207 BC (Qin Dynasty).
Japan's Suzhou bearing has been very concerned about the rolling mill inspection and sealing, no oil leakage phenomenon; the main part of the rolling mill repair process in the Japanese bearing, Suzhou bearing, remove the cover, check the expansion, if you can not solve the problem, due to freedom The expansion mill body is blocked, causing the hollow shaft gear oil ring and the bearing in Suzhou, Japan to seriously affect the safe operation of the rolling mill. Usually, the temperature of the bearing rises slowly as the operation starts, and reaches a steady state after 1-2 hours.
Therefore, good lubrication of bearings in Suzhou, Japan is an effective measure to reduce bearing friction and wear. In addition, the lubrication of the bearing also has various functions such as heat dissipation, rust prevention, sealing, and shock mitigation. The effect of bearing lubrication can be briefly explained as follows: a. Forming a gap between the two rolling surfaces or the sliding surfaces that are in contact with each other The oil film separates the two surfaces, reducing friction and wear on the contact surfaces. The rolling sound of the bearing in Suzhou, Japan, uses a sounder to check the size and sound quality of the rolling sound of the running bearing. Even if the bearing is slightly peeled off, it will emit abnormal sounds and irregular sounds, which can be distinguished by the sounder. . The middle retaining ring is a separable ring in a roller bearing having two or more rows of rollers for isolating the two rows of rollers and guiding the rollers. b. When using oil lubrication, especially when using circulating oil lubrication, oil mist lubrication and fuel injection lubrication, the lubricating oil can take away most of the friction heat inside the bearing and play an effective heat dissipation effect. c. When grease lubrication is used, foreign matter such as dust can be prevented from entering the bearing and sealing. d. Lubricants have the effect of preventing metal corrosion. Lubrication of bearing lubrication has an important influence on the fatigue life of rolling bearings and friction, wear, temperature rise, vibration, etc. Without normal lubrication, the bearings cannot work. e. Extend the fatigue life of the bearing.
China's bearing industry has achieved remarkable achievements. If the lubrication and installation parts are suitable, the bearing temperature will rise sharply and abnormal temperature will occur. At this time, it is necessary to stop the operation and take necessary precautions.
