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 whirling behavior at pivot supported condition by measuring the time history waveform on shaft with parameter of vibrated Frequency changes)

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 whirling behavior at pivot supported condition by measuring the time history waveform on shaft with parameter of vibrated Frequency changes)

This report describes the study on the lubrication characteristics of porous journal bearings as a DC spindle motor's bearing system made with oil impregnated sintered materials having some hydrodynamic shapes. Herring Bone (I & II), Three Lobed Type or Sleeve as radial hydrodynamic...
