The detailed method for determining the near damage caused by the full use is as follows:
1) Using the bearing operation monitoring instrument, such as the iron spectrometer or SPM or I-ID 1 bearing operation monitoring instrument to determine the bearing operation status and when the bearing should be repaired; this is the most convenient and reliable method .
For example, when using the HD 1 type instrument; when the pointer is close to the danger zone by the warning zone; and the pointer does not come back after adopting the method of improving the smoothness, etc.; it can be found that the bearing itself is a problem; at this moment, when the danger zone is not entered; Repair the bearing. After all, it is far from the danger zone to start repairing; it can be adjusted by experience.
The use of such instruments; can fully utilize the potential of bearing operations; repair the bearings in time; and prevent the occurrence of problems; it is safe and economical.
2) Use simple things to monitor in the case where the above instruments are not available; the operator can hold the round bar or the wrench and other things that are closest to the outer casing of the bearing; the ear is ashamed to monitor the sound of the bearing from the thing; It can also be modified with a medical stethoscope.
The normal bearing working sound should be uniform, smooth and not sharp sound, and the abnormal bearing working sound has a lot of intermittent, impact or sharp sound. First of all, you should get used to the normal bearing working sound, and then you can grasp the abnormal working sound of the bearing; then accumulate through the practical experience; and further can dissect what kind of abnormal sound corresponds to what kind of bearing is not normal. Representation. There are many types of abnormal sounds in bearings; it is difficult to tell;
