1. Bearing abnormal operation condition and the corresponding countermeasures
| conditions | Speculate reasons | measures |
Abnormal temperature rise | Grease too much or too little | After checking, inject the right amount of lubricat |
| Load increased | Adjust load, and modify bearing clearance or cooperate with clearance | |
| Bad installation | Improve the bearing process, installation accuracy, and the size of the prestressing force | |
| Cooperate with surface peristalsis or bearing external friction | Adjust precision or change the bearing | |
Big vibration | Bad installation | Fixed axis or shell with precision, and adjust the preload |
| Other things incasion | Improve the shaft and shell surface cleanliness, and improve the installation way | |
| Bearing wear or deformation | Change the bearing | |
| Oil leakage or discoloration | Too much grease or seal rickety, outside oil, water invasion, etc | Adjust the grease capacity or replace the seal form, and improve the bearing work environment |
| Big noise | Bearing damage, peel, and clearance is too large | Change the bearing |
| Other things invasion | Clean parts, replace the seal device, and use clean grease |
2. Common injury and corresponding countermeasures in bearings
| Types | Damage phenomenon | Reasons | Measures |
| Stripping | Groove surface and part of the rolling surface have damage like fish scales | Bearing internal clearance is too small. Improper or inadequate greaseAxial load changed Corrosion Bad installation | Choose the suitable internal bearing clearance to choose lubrication method and grease. To select the supporting bearing axial clearance. Comprehensive anti-rust process to bearing. Establish a reasonable accuracy |
| Outer and inner ring fracture | Interference larger , lager impact load stripping or burn extension. Cooperate with shaft or shell round is too large | Choose the suitable cooperation. Set stable load rounded corners on cooperate surface is less than bearing corner | |
| Electrolytic corrosion | Rolling surface appears edm produce the melting point, and the sureface has a small indentation | Current through the bearing produced sparks | Implement insulation in bearing. Set current bypass not through bearing |
| Rust corrosion | Bearing surface and roll surfaces are rusted | Environment humidity is bigger. There is water or corrosion material into the inernal bearing | Improve sealing device and improve bearing storage environment |
| Creep deformation | Rings movement relative axis or axial shell | Sleeve tighten is not enough. Interference shortage | Appopriate strengthen. Increase the interference |
| Holder rupture | There is distortion, wear and fracture | Shock and torque is too large. Improper lubricant. Bad installation | Reset load. To choose the suitable lubricant type. Reduce the installation error, improve installation method |
