✦ Synopsis

The most fundamental cause of noise and unsteady running of rolling bearings is the so-called varying compliance vibrations. These are parametrically excited vibrations that occur irrespective of the quality and accuracy of the bearing. Varying compliance of the bearing assembly can give rise to both radial and axial displacements of a shaft supported by rolling bearings. In this study, however, attention is focused on radial vibrations of radially loaded bearings having a positive radial clearance. Previous studies of this phenomena are quasi-static in approach--the inclusion of inertia forces reveals characteristics not previously recognized. Examples of theoretical solutions obtained through digital simulation are presented and comparisons with experimentally obtained results are made.
