Mechanical parts outage detection - bearing knowledge
Mechanical parts for the use of machinery and play a crucial role, so we must carry out regular maintenance and maintenance, in order to improve the equipment performance, prolong the service life of mechanical parts, when the machine downtime, need to correlation detection, mechanical parts to ensure the safe use of spare parts.
1, it is important to keep the bearing and lubrication clean.
Need before checking surface cleaning machine, and then remove the perimeter of the bearing parts.
Oil seal is very fragile parts, so need to carefully remove, not excessive force, and then carefully check oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace the bad oil seal will cause the damage of the bearing and severe equipment downtime.
2, check the lubricant with little lubricant in friction between two fingers, and if the presence of pollutants, can feel out, or in the back with a thin layer of lubricant, then seal of inspection.
3, replace the lubricant oil lubrication bearing after xie used engine oil, possible, impregnated with fresh oil and let the machine in low speed rotation for a few minutes.
As far as possible make the oil collecting residual pollutants, then spilled oil in addition to these, the oil before use it's best to filter it.
Grease lubrication bearing in replacing grease used by Joe in addition to the editor should avoid to any part of the bearing with a cotton by Angle, because these residues fiber may wedged in between the scroll and damage, especially the application of small bearing more need to pay attention to this problem.
4, covering exposed bearing inspection bearing, don't let bearing exposure to pollutants or moisture environment.
If the job is interrupted, should with oil film, paper or similar material by machine.
If don't have to remove and may perform inspection of cleaning without masking of bearing, to coating with brush with petroleum solvent (
Cleaning and dry with a lint-free cloth or with compressed air to blow dry,
Be careful not to let the bearing component starting rotation)
