Three commonly used methods for loading and unloading imported IKO linear bearing faults

Early detection of IKO failures is of great benefit to both mechanical equipment and production. How can we better do this work?

If you do not through the dismantling inspection to identify or predict whether the IKO bearing failure, which is very beneficial to improve productivity and economy. There are three main methods of fault identification for linear bearings:

First, through the special person or listener, listening to the sound recognition of the bearing bearing through the sound to identify the need for a wealth of experience. Must be fully trained to recognize IKO bearing and non-bearing sounds. To do this, we should try our best to do this work. The sound of the linear bearing can be clearly heard with the earphone or the sound bar attached to the housing.

Second, through the IKO bearing lubricant status recognition First, the sample analysis of the lubricant, whether the degree of contamination through the presence of foreign matter or metal powder, etc. to determine. This method is especially effective for bearings that cannot be observed close to or large bearings.

Third, through the IKO bearing operating temperature identification This method is a comparative identification method, limited to use in the operating conditions do not change the occasion. For this reason, continuous recording of temperature must be performed. When a fault occurs, not only the temperature rises, but also irregular changes occur.

(1) The resultant force of the applied force should be passed through the axis of the imported bearing as much as possible, which requires that the force applied point is symmetrical and stable, and the force is applied through the spherical surface or parallel to the axis.

(2) The size of the force should be even and uniform, and there should be no impact. This requires the use of oil pressure or the use of tools capable of exerting a stable pulling force or pressure. In fact, it is necessary to use hammers and soft copper sleeves. No chipping metal is cushioned and the tapping force is as gentle as possible. It is best to use a copper or copper hammer for hammering.

(3) Avoid applying force through the rolling elements. This requires that when the inner ring (shaft ring) is assembled and disassembled, the inner ring is used to apply force, and when the outer ring is assembled or disassembled, the outer ring is used to apply force.

(4) The drag force should be continued to the required degree. For example, when installing the bearing, stop applying force when the bearing is just installed to the correct position to ensure that the end face of the ferrule (gasket) abuts against the shoulder face of the seat hole or the shaft. You can neither squeeze too tightly nor hold it in place.

The criteria for judgment vary depending on the mechanical properties and degree of importance and the inspection period. If the linear bearing parts are broken and defective, and the raceway surface rolling surface is peeled off, the imported bearings will not be reused and must be replaced.
