SKF roller bearing surface roughness to install a few common reasons
by:Waxing2020-10-24
By heating bearing or bearing seat, by using thermal expansion will fit into a loose fit installation method.
Installation method is a kind of common and energy saving.
This method is suitable for interference quantity larger the installation of the cylindrical roller bearing, the bearing before hot charging type or separable bearing ring into the fuel tank 80 - uniform heat
100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and shoulder joint is not tight, bearing axial fastening again after cooling.
Bearing outer ring and light metal bearing seat tight fit, by heating the hot charging method of the bearing, can avoid the mating surface scratch.
Heating tank with bearing and should be at a certain distance from the bottom of a mesh, or hanging hooks in the bearing, SKF bearing cannot be on the bottom, in case of heavy impurities into the bearing or uneven heating, fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring.
To shaft bearing before installation, must first remove the bearing a coat of fixed pin, the shaft neck at the same time clean exterior burnish is smooth, and the journal oil anti-rust and lubrication (
Allows for a slightly bearings on the shaft rotation)
。
Coating on surface of the bearing and cylindrical roller bearing with lubricating oil, the SKF bearing load bearing.
Pushed to the required location for installation.
Fixed bearing bolts do not tighten, let bearing coat in bearing internal energy.
Also installed on the same shaft, on the other side of the bearing and shaft turning laps, make automatic alignment position bearing itself.
Then good bearing bolts.
Eccentric sleeve.
The eccentric sleeve installation is firm, finally lock hex bolt on the eccentric sleeve bearing is precision components, cylindrical roller bearing and oil pollution, will not be able to run.
Bearing in addition, all sealed maintenance-free with oils have, at least 14% of the pollution is all only in a small area of the premature failure of the bearing using SKF bearing significant result.
Bearing has excellent manufacturing and design capabilities, can provide all kinds of bad working conditions, sealing solutions.
