Mechanical parts play a vital role in the use of machinery, so we must carry out regular maintenance and repair. In order to improve the service performance of mechanical equipment and prolong the service life of mechanical parts, when the machinery is stopped, it is necessary to detect the correlation of mechanical parts to ensure the safe use of parts.
1. It is important to keep the bearings and lubrication clean.
Clean the machine surface before inspection, and then remove the parts around the bearing. The oil seal is a very fragile part, so it is necessary to remove it carefully without exerting excessive force, and then carefully check the oil seal and its surrounding parts. If the oil seal has shown bad symptoms, it must be replaced. Poor oil seals will lead to bearing damage and severe equipment shutdown.
2. Check lubricant
Rub the two fingers with a little lubricant. If there are pollutants, they can be felt, or apply a thin layer of lubricant on the back of the hand, and then conduct light sealing inspection.
3. Replace lubricant
After draining the old oil from the oil lubricated bearing, if possible, fill it with fresh oil and let the machine rotate at low speed for several minutes. Make the engine oil collect residual pollutants as much as possible, and then drain the engine oil. It is better to filter the engine oil before use.
When replacing grease for grease lubricated bearings, the arbor remover with cotton joint angle to any part of the bearing shall be avoided, because these residual fibers may wedge between rolling elements and cause damage, especially for the application of small bearings.
4. Cover exposed bearings
When checking the bearing, never expose the bearing to pollutants or moisture. If the work is interrupted, the machine shall be covered with oil paper plastic sheet or similar materials.
If the uncovered bearing can be cleaned without disassembly and inspection, the brush used for coating shall be dipped with white spirit for cleaning, and then a piece of lint free cloth shall be used for wiping or compressed air shall be used for drying (be careful not to let the bearing assembly start rotating).
