STUDY OF THE VIBRATION CHARACTERISTICS OF BEARINGS.

The effect of waviness, measured in a broad band, on the bearing vibration is discussed on the basis of SKF experimental data. The effect of the number of balls on the radial bearing vi bration, as measured in octave bands, is shown experimentally and a comparison with theory made. Tests with vibration attenuating bearing mounts are reported. Radial vibration spectra oings have been studied for comparison with theory presented in Special Report AL61L032. A method for evaluating the damping from the vibration spectrum of a bearing is presented. Trial runs on the vibration tester for large bearings are reported. Author
