Natural Vibrations on Outer Ring of Cylindrical Roller Bearing.

Abstract

An investigation was carried out to elucidate the nature of the natural vibrations on the outer ring of the cylindrical roller bearing. In this paper, the vibrations of six outer rings of the cylindrical roller 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 taken toward the measured natural frequencies. From the experiments, analysis and considerations, the natural vibrations on the outer ring itself of the cylindrical roller bearing were clarified, and it was found that the natural vibrations could be calculated by the theory of Love and the extended theories of Kirkhope.
