Daily maintenance is very important to reduce and avoid motor failure in operation, the most important link is to strengthen the inspection and timely elimination of any abnormal causes. After the occurrence of an accident, it is necessary to carefully analyze the accident and take countermeasures, which is essential to reduce the number of accidents, reduce the maintenance workload, and improve the operation efficiency of the micro gear motor.
If the bending degree of the shaft of the micro reducer is not large, it can be trimmed by grinding; If the bending exceeds 0.2mm, the press can be used for dressing, the surface will be polished after correction, and the original can be restored; If the bend is too large and can not be repaired, it should be replaced in time.
When the journal wear is not large, a layer of chromium can be plated on the journal, and then polished to the required size; When the wear is serious, surfacing welding can be used first, and then trimmed to the standard size; When the journal wear reaches the point where it cannot be trimmed, it should be replaced.
When the transverse crack depth of the shaft crack or fracture shaft does not exceed 10% to 15% of the shaft diameter, and the longitudinal crack does not exceed 10% of the shaft length, surfacing welding can be carried out first and then trimmed to meet the standard. If the cracks and cracks are too severe, consider replacing them.
The gap between the shell and the end cover is too large and can be repaired by surfacing welding, such as the bearing end cover is too loose, you can use the punch to repair, and then the bearing is driven into the end cover, for high-power micro gear motor, you can use electroplating and other ways to repair.
