Cause of abnormal noise of bearings
Cause of abnormal noise of bearings
2. Insufficient lubrication (oil level is too low, save improper seal leakage by oil or grease);
3. Bearing clearance is too small or too large (plant issues);
4. Bearing mixed impurities such as sand or soot, played abrasive effect;
5. Bearing mixed with water, acids and other dirt or paint, play a corrosive effect;
6. Bearing housing bore clamp is flat (bad seat hole roundness or housing bore distortion is not straight);
7. Bottom surface of the horn bearing uneven (resulting in deformation of the housing bore even bearing cracks);
8. Bearing hole with debris (residual chips, dust, etc.);
9. Eccentric ring (across adjacent parts and friction);
10. Subject to additional load bearing (bearing by the axial limp tight, or a shaft has two fixed end bearings);
11. Bearings and shaft too loose (smaller diameter shaft or adapter sleeve not tighten);
12. The bearing clearance is too small, too tight (tight sets tightened too overdone) rotates.
