09 analysis of the main causes of non-standard bearing vibration, imperial vibration of rolling bearings are basically caused by the vibration of the bearing ring, the cause of the vibration and bearing structure, the stiffness, precision.
In the terms and conditions of the installation and bearing use can also lead to the cause of the vibration.
Assumption of bearing inner ring raceway with larger radial corrugated, then its inner ring rotation bearing outer ring will produce radial vibration.
Bearing inner ring radial vibration ripples will lead to not only outer ring, but will also cause the axial vibration of outer ring, bearing under axial load is also easy to make when bearing the inside and outside the circle of axial some change in the relative position, so inside is rotating bearing outer ring will produce axial vibration.
For high-speed operation of the imperial rolling bearing, because of his ripple caused by the vibration frequency, will be equivalent to the rotation frequency of the vibrator shaft, which is the resonance phenomenon.
