Overheating of high-speed precision angular contact ball bearings is the main culprit of bearing failure. The root cause is that the heating of bearings is generally an alarm signal for abnormal equipment operation. If it is not resolved as soon as possible, it may cause chain reactions such as equipment damage. There are many reasons for bearing heating: (1) Low bearing precision and unreasonable model selection. Bearing precision is not up to standard or there is a difference in model selection. Because the equipment cannot meet the most ideal operating standards, it will cause the bearing to heat up visually. Solution: Use bearings with the required precision grade specified by the company. (2) Large vibrations. For example, the poor alignment and processing technology of the coupling does not meet the requirements, and the motor rotor has dynamic and static imbalances, poor basic stiffness, weak feet, rotational chatter and surge. Many motor rotors are damaged by medium erosion or solid impurities during operation, or the shaft is deformed, which will cause unbalanced centripetal force, which will cause the bearing to heat up and vibrate, and the dovetail guide rail will be seriously damaged until it is destroyed. (3) Insufficient refrigeration Insufficient refrigeration is generally reflected in: pipeline blockage, problems with the use of coolers, and poor cooling effects. The cooler of the lubricating pipeline is fouled and blocked, which will lead to a decrease in cooling effect, especially in summer production. The fouling of the cooler is relatively serious, and the phenomenon of high bearing temperature is often reported in many job sites. The more efficient treatment method is to carry out acid pickling passivation scale cleaning on the cooler before entering the summer every year. (4) Unreasonable assembly Unreasonable assembly is another important factor for bearing heating. Since the correctness of the bearing installation is directly related to the service life and the accuracy of the server, it is stipulated in the installation that the axis of the shaft and the axis of the bearing hole must overlap. If the bearing assembly is skewed, the precision is low, and the bearing has a deflection value, it will generate torque when rotating, causing the bearing to heat up or be damaged. In addition, the bearings will cause vibrations, amplify the noise, and increase the temperature. Only when the torque is accurate can the rotation be stable! (http:///product_ayycjf.html)
