What Are The Reasons And Prevention Methods For The Bearing Cracking And Abnormal Noise Of The Reducer?
1. The bearing is broken:
1.1 Reason analysis:
The bearing fracture of the reducer mainly occurs in the driving shaft bearing. The main reason is that when the driving shaft moves, axial sliding will occur between the inner ring of the bearing and the rollers, causing the inner ring of the bearing to move axially, causing the inner bearing rollers to move first. damage;
1.2 Prevention and elimination methods:
Increase the interference between the inner ring and the shaft, or add a retaining ring on the outer side of the inner ring of the bearing to prevent axial movement;
2. The reducer has abnormal noise
2.1 Reason analysis:
a. Reducer overload operation;
b. The load of the working machine is unbalanced;
c. Lubricating oil deterioration;
d. The gear tooth surface is worn or the manufacturing quality is poor;
e. The bearing clearance is too large or too small;
f. There are adhesions on the tooth surface;
g. There are sundries in the box.
2.2 Prevention and elimination methods:
a. Operate according to specifications;
b. Adjust the balance;
c. Drain the deteriorated lubricating oil in the reducer, clean it and replace the qualified lubricating oil;
d. Send to the repair shop for overhaul and replacement parts in time;
e. Adjust the bearing clearance;
f. Check and clean up;
g. Drain the oil for cleaning.
