Installation Method Of Skf Bearing

Method Of Skf Bearing

For tapered hole SKF bearings, the inner ring is always installed with an interference fit. Different from the Method Of Skf Bearing cylindrical hole SKF Bearing, the interference of the conical hole SKF Bearing is not determined by the selected shaft fit tolerance,

but by the propulsion distance of the SKF Bearing on the conical journal, shaft sleeve or withdrawal sleeve. The radial internal clearance of SKF Bearing decreases with the advance of SKF Bearing on conical journal. By measuring the reduction value, the Method Of Skf Bearing degree of interference and the tightness of the fit can be determined.

When installing self-aligning ball SKF Bearing, carb ring roller SKF Bearing, spherical roller SKF Bearing and high-precision cylindrical roller SKF Bearing with conical hole, the reduction value Method Of Skf Bearing of radial internal clearance or

the axial propulsion distance on the conical base shall be determined as the measure of interference. See the relevant product section for the Method Of Skf Bearing guidance values of clearance reduction and axial propulsion distance.

Small SKF Bearing

Small SKF bearings can be pushed onto a conical base using nuts. In the case of shaft sleeves, sleeve nuts are used. The small disassembly sleeve can be pushed into the SKF Bearing Hole with nuts. The nut can be Method Of Skf Bearing tightened with hook wrench or pneumatic wrench. Before installation, add a little oil to the surface of journal and sleeve.

Installation Method Of Skf Bearing

Large and medium SKF Bearing

The installation force required for large SKF bearings is significantly Method Of Skf Bearing increased and hydraulic nuts and / or oiling methods shall be used.

The above two methods can significantly simplify the installation process. The oil filling equipment required to operate the hydraulic nut and use the oil filling method is Method Of Skf Bearing supplied. For details of these products, see the relevant section in the online catalog “maintenance and lubrication products”.

When installing SKF Bearing with hydraulic nut, it must be positioned on the threaded part of the journal or the thread of the sleeve to make the Method Of Skf Bearing annular piston close to the inner ring of SKF Bearing, the nut on the shaft or the retaining ring installed at the shaft end.

Press the oil pressure into the hydraulic nut through the oil pump to move the piston axially with the force required for accurate installation. Method Of Skf Bearing Using hydraulic nuts, install the spherical roller SKF Bearing onto the

Using the oil injection method, the oil is injected between SKF Bearing and journal under high pressure to form an oil film.

This oil film separates the mating surfaces and significantly reduces the friction between the mating surfaces. This method is generally used when SKF Bearing is directly installed on conical journal, but it is also used to install SKF Bearing on tight set sleeve and push sleeve specially prepared for oil injection method.

The oil pump or oiler generates the necessary pressure to inject oil between the mating surfaces through the groove and oil distribution channel on the shaft or sleeve. When designing SKF Bearing layout, necessary grooves and channels must be arranged on the shaft.

The spherical roller SKF Bearing is installed on the withdrawal sleeve with oil groove. The withdrawal sleeve is pressed into the SKF Bearing Hole by injecting oil into the mating surface and tightening the screws in turn.

The tapered hole bearing can be directly installed on the tapered journal, or it can be installed on the cylindrical journal with the tightening sleeve and disassembly sleeve as the intermediary. However, in any case, the interference of the inner ring of the tapered hole can be measured according to the reduction of the clearance of SKF Bearing.

The reduction of radial clearance is the difference between the radial clearance of SKF Bearing before and after installation. The original radial clearance of SKF Bearing shall be measured before installation, and the clearance shall be measured frequently during installation until the radial clearance reduction corresponding to the ideal interference is achieved

The measurement of radial clearance reduction can also be replaced by the measurement of the propulsion of SKF Bearing on conical journal.

For the standard taper of 1:12, the reduction of radial clearance is about 1 / 15 of the axial thrust. In this proportion, for the solid shaft, the interference of the mating surface is only 75% ~ 85%, which plays a role in expanding the inner ring.

The reduction of radial clearance of large spherical roller SKF Bearing and cylindrical roller bearing is usually measured with feeler gauge. Note that for spherical roller SKF Bearing, the radial clearance at the two rows of rollers must be measured from the two end faces respectively. Only when the clearance value at the two rows of rollers is the same, can the inner ring and outer ring be relatively positive.
