EXPERIMENTAL RESEARCH OF VIBRATORY SLIPPING OF THE SHAFT FASTENED WITH TIGHTNESS IN THE BUSHING

Abstract

The paper deals with the process of vibratory slipping of the shaft fastened in the bushing, when the shaft is acted by axial force and the bushing is excited in axial direction. The experimental setup was mounted for determining the characteristics of shaft slipping. The graph of shaft insertion depth is given without excitation of the bushing and exciting it with different frequency vibrations.  The dependences of shaft insertion duration on oscillation frequency and amplitude with different pressing forces are provided. It was found that when the bushing is excited in axial direction, the pressing force may be significantly reduced. Shaft insertion time depends on the excitation frequency and amplitude.
