Determination Method Of Iko Bearing Replacement

Iko Bearing Replacement

The specific judgment method of whether IKO bearing should be Iko Bearing Replacement reported for repair, that is, the specific judgment method of IKO bearing has been fully utilized and near damage is as follows:

1) Using IKO bearing working state monitoring instrument

It is a convenient and reliable method to judge the working state of IKO bearing and decide when IKO bearing should be repaired by using such Iko Bearing Replacement instruments as Ferrograph or SPM or i-id-1 IKO bearing working state monitoring instrument.

For example, when HD-1 instrument is used, when the pointer approaches the dangerous area from the warning area, and the pointer does not return after taking measures to improve lubrication, it can be determined that it is the problem of IKO bearing itself. At this time, IKO bearing can be reported for repair before entering the dangerous area. How far away from the dangerous area to start the repair can be adjusted by experience.

Using such an instrument, we can make full use of the working potential of IKO bearing, report IKO bearing Iko Bearing Replacement for repair in time, and avoid faults. It is and economical.

Determination Method Of Iko Bearing Replacement

2) Monitor with simple tools

In the absence of the above instruments, the operator can hold a round rod or wrench and other tools to collide with the machine shell close to the IKO bearing, shame his ears on Iko Bearing Replacement the tool and listen for the IKO shaft sound transmitted by the tool. Of course, it is also possible to refit the medical stethoscope.

The IKO shaft shall have a normal screeching sound, while the IKO shaft shall have a normal screeching sound. First, get used to the normal IKO shaft carrying sound, and then you can Iko Bearing Replacement grasp and judge the abnormal IKO shaft carrying sound.

Then, through the accumulation of practical experience, you can further analyze what kind of abnormal sound corresponds to what kind of IKO bearing abnormal phenomenon. There are many types of abnormal sounds Iko Bearing Replacement of IKO bearings, which are difficult to speak and mainly rely on experience.

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, Iko Bearing Replacement 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.

The small tapered hole SKF Bearing cannot be measured with a feeler 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 elastic 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.
