1. Contact fatigue failure
Contact fatigue failure refers to the failure of the working surface of IKO imported bearings due to the alternating stress. Contact fatigue spalling occurs on the bearing working surface, often accompanied by fatigue cracking, first from the maximum alternating shear stress below the contact surface, and then extended to the surface to form different peeling shapes, such as pitting or pitting. Peeled into small pieces called shallow peeling. Due to the gradual enlargement of the exfoliation surface, it tends to expand deeper and form deep exfoliation. Deep exfoliation is a source of fatigue in contact fatigue failure.
2, wear and tear
Wear failure refers to the failure of the relative sliding friction between the surfaces resulting in the continuous wear of the metal on the working surface. Continued wear and tear will cause gradual damage to the bearing parts and eventually lead to loss of dimensional accuracy of IKO bearings and other related problems. Wear may affect the shape change. The increase of the clearance and the change of the surface of the working surface may affect the lubricant or cause the pollution to a certain extent, resulting in complete loss of the lubrication function, thus causing the bearing to lose the rotation precision or even the normal operation. Wear failure is one of the common failure modes of various types of bearings. It is usually classified into the most common abrasive wear and adhesive wear according to the form of wear.
1) Instrument detection
Using a spectrometer such as a spectrometer or SPM or a new VIB05 detector to determine the operating state of the bearing to determine whether maintenance or replacement should be performed is the most convenient and reliable method.
For example, when using the VIBO5 detector, this is a microprocessor-based machine state detection instrument with vibration detection, IKO imported bearing status analysis and infrared temperature measurement. The operation is simple, and the status alarm is automatically indicated. It is very suitable for the field equipment operation and maintenance personnel to detect the equipment status, find problems in time, and ensure the normal and reliable operation of the equipment.
With such an instrument, the bearing working potential can be fully utilized, the bearing warranty can be timely and the failure can be avoided, and it is suitable for young workers to make up for their lack of experience.
2) Manual detection
In places where the above instruments are not available, it can be detected using a monitoring instrument similar to that of a medical stethoscope. Experienced operators can also use the tools such as round bars or wrenches to resist the outer casing of the machine, and use the ear to monitor through the tool. The sound of the bearing.
The normal IKO imported bearing running sound should be uniform, stable and not harsh, and the abnormal bearing running sound is intermittent, impact or harsh sound.
This method is suitable for the operation of experienced staff, which mainly depends on the accumulation of staff experience.
