STUDY OF N CHARACTERISTICS OF BEARINGS.

Abstract

A discussion is given of the vibrations induced by the variable compliance of a radially loaded bearing and of vibrations from other sources operating at the ''ball passage'' frequency. Narrow band low frequency vibration spectra (up to 200 cps) are shown and interpreted with em phasis on discrete frequencies that can be ex plained by bearing kinematics. A detailed ex perimental investigation was conducted of the amplitudes occurring under various loads at the ball passage frequency and its second harmonic. It is shown that the results are in excess of the amplitudes predicted theoretically at these fre quencies. A discussion is presented regarding the relative importance of several causes of low frequency vibration. Tests are reported on the effect of fit between bearing O.D. and hous ing on the vibrations observed at the housing O.D.
