First, determine the best time for bearing repair
The rolling bearing work to which state into the repair is better to determine the rules and characteristics of this from bearing damage. Damage to t he largest number of small and medium-sized bearings, usually fatigue and excessive wear rings or rolling bodies. Wear when the bearing rolling surface into the third stage, or pitting and spalling, the bearings will quickly tend to lapse, then the destruction of the raceway surface is very serious, very difficult to repair, or lose their value to repair.steel ball bearings

But bearing the above phases before, wear relatively minor, fatigue may occur only in the surface layer of the rolling surface of a few microns to tens of microns depth, and thus in the time that the bearing repair, you can use a small price to get a better The repair effect. In short, the repair rolling bearings when the bearings have been working for quite a long period of time has been fully utilized before the damage appears to enter the repair is most appropriate.

, Bearing the timing of repair metho d

Bearing specific judgments, whether it be to repair the bearing has been full use of the near destruction of specific judgment as follows:ball bearing suppliers

1) the use of the bearing operating condition monitoring equipment

The working status of condition monitoring instruments, such as iron spectrometer or SPM or the I-ID-type bearings to determine the bearing and the bearing when it should be the repair, which is the most convenient and reliable method.

For example, when using the HD-1 instrument, when the pointer by the warning area near the danger zone, while taking the pointer did not go back to improve lubrication and other measures to determine the bearing itself, then you can take advantage of not entering the danger zone , bearing repair. Exactly how far away from the danger zone began to repair may experience adjustment.miniature bearing

Use of such instruments, can take advantage of bearing potential, and in a timely manner bearing repair and avoid failure, is a safe and economical.

2) the use of simple tools to monitor

Occasions do not have the equipment, the operator can be armed with a round bar or wrench and other tools are inconsistent with the machine closest to the bearing shell parts, ears ashamed of the bearing running sound monitoring tools coming on the tool, of course, the use of medical stethoscope modified can also .

Normal operation of the bearing sound should be uniform, smooth, harsh voice, instead of the normal operation of the bearing sound, there are a variety of intermittent, impact or harsh sound. First to get used to the normal operation of the bearing sound, and then will be able to grasp the sound of the judge is not normal bearing operation, then through the accumulation of pra ctical experience, further analysis of what normal sound corresponds to what kind of bearing is not normal. Bearing type of abnormal sound is difficult to explain in words, depends mainly on the accumulation of experience.
