First, determine the best opportunity for bearing repairs. It is better to turn the bearing operation to what kind of condition to turn into repair; this should be judged from the damage rules and characteristics of SKF imported bearings. The damage of the most used small and medium-sized bearings; usually in the ferrule Or the fatigue and excessive wear of the roll body. When the bearing rolls over and the appearance enters the third period of wear; or the pitting and falling off have occurred; the bearing will quickly become ineffective; at this moment, the damage of the raceway appearance is already serious; Patching is difficult; or the patching value has been lost.
However, the bearing is before the above period; the wear is fine; the fatigue may only occur in the depth of several micrometers to several tens of micrometers under the outer surface of the tumbling outer surface; therefore, the bearing is repaired at this moment; it can be better with a small value. The repairing effect of the rolling bearing; the repair period of the rolling bearing is to be used for a period of time when the bearing has been operating properly; it has been fully utilized; and it is most appropriate to enter the repair before the damage is presented.
Second, the bearing repair opportunity determination method SKF imported bearings can be reported for detailed discriminating measures; that is, the bearing has been fully utilized and the near-damage is presented in detail 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 notice area; and the pointer does not come back after adopting the method of improving the smoothness, etc.; it can be found that the SKF imported bearing itself is difficult; at this moment, the danger zone is not entered. When the bearing is repaired. 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 the like to the most closely related to the outer casing of the bearing; the ear is ashamed to monitor the sound of the SKF imported bearing from the east and west. Of course, the use of medical stethoscope modification can also.
The normal SKF imported 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 work sound, and then you can grasp the abnormal working sound of the bearing; then accumulate through the practical experience; and further can distinguish what kind of abnormal sound corresponds to what kind of bearing abnormal appearance There are many types of abnormal sounds in bearings; it is difficult to say; it is mainly based on experience accumulation.
