Talking about the Factors of Heating of DC Motor Rolling Bearings
This paper is mainly about the introduction of DC motor rolling bearings, and focuses on the factors of DC motor rolling bearing heating.
Talking about the Factors of Heating of DC Motor Rolling Bearings
1. If the bearing is damaged, it should be replaced in time.
2. The grease grade is incorrect or too much or too little. Generally, No. 3 lithium base grease or No. 3 complex calcium base grease, ZL3 (SY1412-75) or complex calcium base grease is used. After cleaning the bearing and cover, add grease to the net volume of about 1/2.
3, the sliding bearing lubricant is not enough or there are impurities, or the oil ring is stuck, repair can be.
4. The bearing and the end cap are too loose (outside or too tight). Spray the metal on the journal when it is too loose; rework when it is too tight.
5. The bearing and the end cap are too loose (out of the outer circle) or too tight. End caps when loose; rework when overtight.
6. The end caps or bearing caps on both sides of the motor are not assembled. Re-flattening.
7. The transmission belt is too tight or too loose, and the coupling is not centered and should be adjusted.
