The purpose of coordination is to make the inner ring or outer ring of the bearing firmly fixed with the shaft or shell, so as to avoid unfavorable axial sliding on the matching surface. This unfavorable axial slide (called creep) will cause abnormal fever, composite Surface Wear (and then make the worn iron powder intrude into the bearing) and vibration problems, so that the bearing cannot play a full role. Therefore, for bearings, due to bearing loa

vibration at three places. The repetition frequency is exactly consistent with the passing frequency of the roller through the inner ring, therefore, it can be regarded as a single fault in the inner ring. When the roller passes through the fault point, it will arouse the structural resonance of the bearing system. As the roller passes through the fault point, this resonance will quickly decay. Generally, experienced engineers can take a look at the sound waveform to determine whether the beari
