In the previous chapter, we introduce the ordinary faults of mechanical screen and solutions. In which, some of the faults are caused by the problem of reducer. In the next, BOEEP will elaborate on the gear reducer failure and solutions.
Problems-1: Vibration
| Main Cause | Solutions |
| Transmission misalignment | Inspection, adjustment and alignment |
| Loose connector, damage of fit precision | Fasten loose bolts |
| Dynamic balance failure | Check rotor dynamic balance |
Problems-2: Excessive Noise
| Main Cause | Solutions |
| Poor lubrication | Replace the lubricating oil |
| Poor meshing of gears | Adjust gear meshing |
| The accuracy of each part is reduced and the wear is serious | Adjust the accuracy of each part |
Problems-3: Seal Leakage
| Main Cause | Solutions |
| Wear of shaft seal or reducer seal | Replace shaft seal or reducer seal |
| Oil level is too high | Adjust to the standard level |
| Bearing or journal damage | Replace bearing or journal |
Problems-4: High Temperature of Bearing
| Main Cause | Solutions |
| Bearing wear gap increases | Adjust or replace the bearing |
| Too much or too little lubricant | Appropriate of adjustment of oil quantity |
| Lubricating oil of poor quality or containing impurities | Replace qualified lubricating oil |
| Bearing loosening | Adjust and tighten the bear seat |
