The correct installation of IKO bearing directly affects the accuracy, service life and performance of IKO bearing. Therefore, the design and assembly Influence Of Iko Bearing department shall fully study the installation of IKO bearing and carry out it according to the operation standards. Operation standard items are usually as follows:
1. Clean IKO bearing and related parts
2. Check the size and accuracy of relevant parts
4. Check IKO bearing after installation
5. Fill lubricant
It is hoped that the IKO bearing package will be opened during installation. During general grease lubrication, IKO bearings are not Influence Of Iko Bearing cleaned, but directly filled with grease. Generally, it is not necessary to clean the IKO bearing for instrument or high-speed use when lubricating with oil.
However, clean the IKO bearing with clean oil to remove the antirust agent coated on the IKO bearing. IKO bearing with rust inhibitor removed Influence Of Iko Bearing is easy to rust, so it can not be placed at will.
The installation method of IKO bearing varies according to the structure, fit and conditions of IKO bearing. Since it is generally shaft rotation, the inner ring needs interference fit. Cylindrical bore bearings are usually pressed in with a press or hot installed. In the case of taper hole, it shall be directly fixed on the taper shaft or installed with tightening sleeve.
Clearance fit is mostly used when installing to IKO bearing seat. When there is interference in the outer ring, it is usually pressed in by press or installed by cold shrinkage method after cooling. Dry ice is used as the coolant. In the case of cold contraction installation, the moisture in the air will condense on the surface of IKO bearing. Therefore, anti rust measures need to be taken.
The tapered hole bearing can be directly installed on the tapered journal, or it can be installed on the Influence Of Iko Bearing 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
by the measurement of the propulsion of SKF Bearing on conical journal. For the standard taper of 1:12, the Influence Of Iko Bearing 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.
The small tapered hole SKF Bearing cannot be measured with a feeler Influence Of Iko Bearing gauge because its radial clearance is too small. A dial indicator can be used to contact the shaft or SKF bearing seat to measure the lifting amount during propulsion.
At this time, attention is paid to the change of radial clearance, and the Influence Of Iko Bearing elastic Influence Of Iko Bearing deformation of rolling element and raceway is not considered. The force used to push SKF Bearing or bearing seat should be roughly equivalent to their weight.
