Commonly used INA self-aligning ball bearing lubrication inspection way - bearings of knowledge
Need before checking surface cleaning machine, and then split INA bearing the perimeter of the 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 self-aligning ball bearing and severe equipment downtime.
With little lubricant in friction between two fingers, and if the presence of pollutants, can feel out, or in the back coating a layer of lubricant, then seal of inspection.
Oil lubrication of INA bearings 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 minor heart ball bearings need more attention to this problem.
Used in some special conditions, adding a small amount of solid lubricant grease, such as add 1 of 3-5% molybdenum disulphide can reduce wear and improve the heat resistant ability to work under pressure.
Is an important characteristic of lubricating oil viscosity, viscosity directly affect the liquidity of lubricating oil and the size of the friction surface is formed between the oil film thickness, the working temperature of lubricating oil viscosity is usually 12 -
Speed the Gao Yingxuan lower viscosity, the more load weight should choose high viscosity.
Oil lubrication methods include: a.
Oil bath lubrication oil bath lubrication is the most common lubrication method, suitable for low, medium speed, lubrication, self-aligning ball bearing part of immersion in the slot, lubricating oil by rotating parts take up, and then flow back to the oil level of oil tank should be slightly lower than the lowest at the center of the roller.
Oil drip lubrication oil drip lubrication is suitable for need to ration oil INA bearing parts, drip oil every 3 - general
A drop of it is advisable to 8 seconds, too much oil will cause the bearing temperature increased.
Circulating oil lubrication oil pump in the conversion of the filter oil transfer to the parts, through the lubricating oil filter cooling after use.
Because of the circulating oil can take a certain quantity of heat, make cool, therefore method is suitable for high speed bearing parts.
Spray lubrication with dry compressed air after the sprayer and lubricating oil mixed form oil mist, spray, air flow can effectively make cool and can prevent the intrusion.
This method is suitable for high speed, high temperature parts lubrication.
Spray lubrication with oil pump into the oil in the high pressure nozzle, into the oil in the other end into the tank.
When bearing at high speed, rolling element and cage with high rotate speed makes the surrounding air air.
Check the self-aligning ball 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 INA bearings, with 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)
Do not clean the encrypted block or dust bearing;
You just wipe the outer surface.
If the INA bearing is need to replace damaged situation.
During regular maintenance downtime time change the self-aligning ball bearing damage selected into a sudden shutdown loss much more economical.
