Experimental study on the lubrication characteristics of porous journal bearings with hydrodynamic shape forming at annular surface under sine-wave vibrated conditions (Examination into the shaft rotating behavior at the starting state by identifying the rotational modes with Frequency Spectrum Analysis of the time history waveform on shaft)

Experimental study on the lubrication characteristics of porous journal bearings with hydrodynamic shape forming at annular surface under sine-wave vibrated conditions (Examination into the shaft rotating behavior at the starting state by identifying the rotational modes with Frequency Spectrum Analysis of the time history waveform on shaft)

This report describes the study on the lubrication characteristics of porous journal bearings, which were made with oil impregnated sintered materials having some hydrodynamic shapes, to apply them for a DC Spindle Motor’s bearing system. Herring Bone (I & II), Three Lobed Type or Sleeve as...
