1. Bearing damage. Check whether the bearing of the ball bearing ball or ball bearing can be damaged. If it is damaged, it should be repaired or replaced.
2. The lubricating oil has impurities, is too dirty, the oil ring is stuck or the trademark is wrong. The oil should be changed; the cause of the jam should be corrected; if the viscosity of the oil is too large, the lubricating oil should be exchanged.
3, the bearing room is lack of oil. Should add grease to overflow 2 / 3 oil chamber or add lubricant to the standard oil line.
4. The grease in the rolling bearing is too much blocked; the temperature of the lubricating oil in the sliding bearing is too low or too high. Excessive grease in the rolling bearing should be removed; or the grease in the oil chamber should be filled to 2/3.
5. The bearing and the shaft, the bearing and the end cover cooperate too loosely or too tightly; too tight will make the bearing deform; too loose is prone to “running sleeveâ€. When the bearing and the shaft cooperate too loosely, the journal can be painted with metal paint; When machining from the beginning, the bearing and the end cap cooperate to loosen the end cap tightly; when it is too tight, it is processed from the beginning.
6. The two caps or bearing caps of the motor are not installed; usually they are not parallel; the bearing is not in the correct orientation. The two caps or bearing caps are flattened; tighten the bolts.
7. The belt is too tight, too loose or the coupling is not properly installed. Adjust the belt tightness and teach the coupling.
8. The wrong type of bearing was replaced during maintenance. Replace the correct type of bearing quickly.
