About motor bearing
Bearing overheating
The problem of bearing overheating is the most frequently dealt with by friend C on site. The characteristics and situations are varied, mainly including:
● Bearing lack of oil. The cause of this problem is the loss of grease, or the deterioration of the grease due to the long running time of the motor.
● Too much oil or too thick oil, dirty oil, mixed with particulate impurities.
● The shaft is deflected, the transmission assembly is incorrectly corrected, which leads to eccentricity, the transmission belt or the coupling is too tight, etc., which causes the bearing to be subjected to extra unbalanced bending and torsion, and friction loss increases.
● The installation accuracy of the end cover or bearing is not high, and the fit is too tight or too loose;
● The pelvic structure of the flange end cover forms a closed space with the equipment, which seals the bearing device. The friction heat cannot be dissipated and accumulates continuously, causing the bearing to overheat.
● Vibration during motor operation is inevitable, and the grease in the bearing may be lost due to it, causing the bearing to generate heat during dry grinding until it is overheated and burned.
● The influence of shaft current. Because the stator magnetic field of large motors is sometimes unbalanced, induced electromotive force is generated on the shaft. The magnetic field imbalance may be caused by local corrosion of the iron core, increased resistance, and uneven air gap between the stator and the rotor, resulting in shaft current and eddy current heating.
