Unscrew the fixed bolt of the bearing.
From the INA bearing, together with the bearing on the shaft will be unloaded.
I on the other end of the shaft should be bearing bolts loosen, so as to avoid mutual don't INA bearing strength and damage.
With Allen wrench to loosen the INA bearing eccentric locking screw, and then with a small iron rod inserted into the roof sink hole on the eccentric sleeve, against the direction of the axis of rotation to play loose eccentric sleeve.
A lot of people in the installation of the bearing use improper installation method, cause the damage of INA bearings.
So how to correctly install INA bearings?
Hope you more comprehensive understanding of the INA bearing installation and disassembly: for clearance fit circle of INA bearings, Suggestions on the fitting surface coated with a thin layer of peristalsis etchant, in case of friction between mating surface corrosion.
Series 390000, outer spherical bearing is through the eccentric sleeve bearing inner ring with fixed axis, eccentric sleeve on the socket head cap screw fastening effect.
In maintenance, a lot of machinist not disassembling the INA bearing, so it is necessary to introduce disassembling 390000 series outside the sphere of INA bearings technical key points and matters needing attention: the correct installation, for the use of INA bearings is very important.
I hope you can in the later use with correct installation method.
When installation, can according to its type and size, select machinery, such as heating or hydraulic method.
Force of INA bearings when installation, must not through the rolling element bearing from a transfer to another INA bearing ring, otherwise it may cause damage to the race.
But in any case, all can't knock directly bearing ring, cage, rolling body or seals.
Eccentric sleeve.
The eccentric sleeve installation is firm, finally lock eccentric sleeve on the socket head cap screw.
Fixed INA bearing bolts do not tighten, let bearing coat in INA bearing internal energy.
Then good bearing bolts.
Also installed on the same shaft, on the other side of the bearing and shaft turning laps, let INA bearings automatic alignment position itself.
Coating on surface of the bearing and the bearing lubricating oil, the INA bearing load bearing.
Pushed to the required location for installation.
Before installation of INA bearings on the shaft, you must first remove the INA bearing a coat of fixed pin, the shaft neck at the same time clean exterior burnish is smooth, and shaft neck with anti-rust and lubrication oil (
Allows for a slightly bearings on the shaft rotation)
。
1, to turn the fan on the dust cleaning clean, avoid during the installation process have any dust into the bearing;
2, the bearing sealing adhesive peel off, remove the card pin shaft;
3, the residual oil within the bearing with a clean cotton paper or soft cloth to wipe clean, then put the rod is clean;
4, within the bearing with a little butter, principle is rather less not more in order to avoid serious impact speed;
5, then cans aluminum skin cut as big as bearing card pin diameter cut one wafer, and in the middle can dig a just through the shaft rod holes, pad between the bearing and the card pin, it reduce the bearing axial distance and parallel movement.
Such as the gap is bigger, will mat several thickening, bearing in 0 distances before and after.
The following 5 mm;
6, the sealed oil seal, add a bit of butter, finally will be back to the graphics card fan.
Try the power is connected, you will find that the voice is much smaller, and thus can be used at least two years.
But need to remind, although sounds small, but because the manual precision co. , LTD. , fall a bit speed slightly.
