Natural vibrations on outer ring itself of ball bearing.

Abstract

An investigation was carried out to clear the natural vibrations on the outer ring itself of the ball bearing. In this paper, the vibration of fifteen outer rings of the ordinary size ball bearing were studied. In the experiments, the outer ring itself was struck in the radial or the axial direction. The sound generated by the strike was measured by a condenser microphone. Natural frequencies of the outer ring itself were determined from the frequency spectra of the sound. Moreover, some theoretical approaches were done about the measured natural frequencies. From the experiments, analysis and considerations, the natural vibrations on the outer ring itself of the ordinary size ball bearing were clarified, and it was found that the frequencies of the natural vibrations could be calculated by Kirkhope's theories and Love's theory.
