滑脂量不对；油质不好，有杂质；轴承无法和轴颈或端盖配合良好；轴承内孔偏

The amount of grease is incorrect; the oil quality is not good, and there are impurities; the bearing cannot fit well with the journal or end cover; the inner hole of the bearing is eccentric, causing friction with the shaft; the motor end cover or bearing cover is not installed flat; the motor is not loaded with the same load Check the inter-connected shafts; improper bearing clearance; bent motor shaft. Troubleshooting method: add grease (1/3 to 2/3 of the volume) according to the regulations; replace the grease with clean; use adhesive to repair the loose parts; The inner hole of the cover is loosened to the proper position; repair the bearing cover, eliminate the rub point; reassemble; recalibrate, adjust the belt tension; replace the new bearing;

Incorrect amount of grease; Poor oil quality and impurities; The bearing cannot fit well with the journal or end cap; The inner bore of the bearing is eccentric, resulting in friction with the shaft; The motor end cover or bearing cover is not installed flat; Failure to check the shaft coupling between the motor and the load; Improper bearing clearance; The motor shaft is bent. Troubleshooting method: add lubricating grease according to the regulations (1 / 3 ~ 2 / 3 of the volume); Replace the grease with clean one; Repair the loose part with adhesive. For the problem of too tight, loosen the grinding journal or the inner hole of the cover to an appropriate level; Repair the bearing cover and eliminate the friction points; Reassemble; Recalibrate and adjust the belt tension; Replace new bearings; Correct the motor shaft or replace the rotor [6].
