After the bearing pressure into the angular contact ball bearing should be flexible rotation without block.
If there are any obvious rotation is not flexible, indicates the size of the shaft is too big, tolerance to downgrade.
Such as bearing pressure into the shaft by hand after the rotation has obvious 'sasha vujacic' feeling, may be the shaft or shaft roundness tolerance is too big.
When control the shaft and the bearing chamber tolerance so also want to control the roundness, at present many domestic manufacturers to control the tolerance, not to control the roundness.
First, the need to stress is that link bearing lubrication and cleaning is very important.
So when we raid was carried out on the bearing, the draw clean bearing situation, and then remove the perimeter of the timken bearing parts.
To pay more attention to the master, it is cowardly of oil seal parts, fruit and was raided and demolition demolition need cockiness special be careful, don't be too much work, so that form the damaged parts.
Then carefully the raid of bearing oil seal and its surrounding parts, if not present adverse symptoms, be sure to switch off and bad seal will cause the damage of the bearing, the bearing cloud differences and the formation of a equipment downtime.
Second, we have raided the bearing lubricant.
Lubrication is very main, but not for bearing, nor for the bearing.
Please note, however, bearing should not add too much grease.
A raid on the bearing lubricant way is: with little lubricant is friction between two fingers, and if no pollutants have no, is a feeling;
Or layer is coated on the back of a lubricant, and then to light a raid.
And then there is a change in the bearing lubricant.
After using oil lubrication bearing is xie used engine oil, bearing remission coating technology introduction and should be.
If can of words, novel should impregnated with oil and machinery are low speed reverse for a few minutes.
As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil.
Note: the oil is using best course before the filter.
And the use of grease lubrication of TIMKEN bearing is a change in grease, by Joe in addition to the unit when avoid without any part of the cotton material come into contact with the bearing.
Due to the residual fiber may wedging between rolling pieces and formation damage induced intended to remove the bearing fault elements, especially the use of small bearings need more attention to this problem.
Third, we need to take care of that was the cover to show angular contact ball bearings.
Raid bearing, absolutely don't let the bearing show in pollutants or moisture.
If workers do outside compose, when the oil film or similar materials cover paper-plastic machinery.
If it is needless to remove and may be imposed under the vision of a raid for cleaning without masking of bearing, with coated with the brush of female with petroleum solvent (
whitespirit)
Cleaning and dry with a lint-free cloth or with compressed air to blow dry,
Pay attention to don't let the noise of bearing component starting to reverse)
。
With a small mirror female, and the type of probe used in the same dentist to raid bearing the orbital plane, connector and bead of female.
No cleaning encrypted block or dust bearing;
You just wipe its external situation.
If the bearing is damaged need to switch off scene.
Are scheduled downtime aftercare period change bearing nearly than for array bearing damage selected into Russia but stop lose much more economical.
Rust paint is characterized by multiple in sealing type motor, the motor sound is very good, when it is assembled but put some time in the warehouse, the motor sound is very big, remove the angular contact ball bearing has serious rust phenomenon.
Many manufacturers will think is a problem of bearing before, after our propaganda, motor factory now have realized mainly is a question of insulating varnish.
Acid varnish comes out of the problem is mainly due to the formation of corrosive substances under certain temperature and humidity, the channel after the corrosion result in bearing damage.
The problem now is only to choose good insulating paint, after drying and ventilation assembly after a period of time.
Bearing life is closely related to manufacturing, assembly, use, and must be made at each link to make the angular contact ball bearings in optimum operation state, so as to prolong the service life of bearing.
