The specific judgment method for whether the bearing should be reported for repair, that is, the specific judgment method for the bearing that has been fully utilized and is about to be damaged is as follows:

    1) Use the bearing working condition monitoring instrument 

It is the most convenient and reliable method to use ferrography, SPM or I-ID-1 bearing working condition monitoring instruments to judge the working condition of the bearing and decide when the bearing should be repaired.

For example, when using the HD-1 type instrument, when the pointer approaches the danger zone from the warning zone, but the pointer does not return after measures such as improving lubrication are taken, it can be determined that it is a problem with the bearing itself. , report the bearing for repair. Exactly how far away from the danger zone to start reporting for repairs can be adjusted by experience.

 Using such an instrument can make full use of the working potential of the bearing, report the bearing for repair in time, and avoid failure, which is safe and economical.

2) Use simple tools to monitor

In the absence of the above-mentioned equipment, the operator can hold a round rod or wrench and other tools against the machine shell closest to the bearing, and put his ear on the tool to monitor the bearing running sound from the tool. Of course, it can also be modified with a medical stethoscope. . the

The normal bearing running sound should be uniform, stable and not harsh, while the abnormal bearing running sound has various intermittent, impulsive or harsh sounds. First of all, you must get used to the normal bearing running sound, then you can grasp and judge the abnormal bearing running sound, and then through the accumulation of practical experience, you can further analyze what kind of abnormal sound corresponds to what kind of bearing abnormal phenomenon . There are many types of abnormal bearing sounds, which are difficult to explain in words, mainly relying on experience accumulation.
