The Effects of Nuer of Balls and Preload on Vibrations
Oct 01, 1997· In this paper, the radial and axial vibrations of a rigid shaft supported by a pair of angular contact ball bearings are studied. The effect on the shaft vibration of varying the preload and the nuer of balls in the bearings is investigated when the bearings are perfect. For perfect bearings the vibrations occur at the ball passage frequency.
Vibration in Bearings - Calculations for Bearing Defect
As the bearing deteriorates further, 1 x rpm sidebands develop, especially around the inner race frequencies. This is due to amplitude modulation as the defect (s) passes in and out of the "load zone." They can occur at +/- 1 x rpm, +/- cage frequency, or +/- ball spin frequency, depending on the situation. Stage Three:

Using Vibration Analysis To Detect Early Failure Of Bearings
The vibration signal from the early stage of a defective bearing may be masked by machine noise making it difficult to detect the fault by spectrum analysis alone. The main advantage of envelope analysis is its ability to extract the periodic impacts and the modulated random noise from a deteriorating rolling bearing.
