• This study proposes the combinations of some hydrodynamic shapes formed on the end or the annular surface of oil impregnated sintered porous bearing as a DC spindle motor's bearing system. Hydro Wave Bearing or Pump In as a thrust hydrodynamic shape, and Herring Bone (Ⅰ&Ⅱ), Three Lobed Type or Sleeve as a radial hydrodynamic shape were proposed, and the total of eight kinds of combinations were produced as thrust-radial coupled bearing. It examines to optimize the hydrodynamic shape combination experimentally as thrust-radial coupled bearing by measuring the lubrication characteristics. This research report is especially referred to the experimental examination for Settling Time, Lissajous Curve diagram or Shaft Whirling by measuring the Time History Waveform of shaft such as the lubrication characteristics under unsteady shaft starting condition. Furthermore this report examines the influence of diametral clearance change to the lubrication characteristics such as above mentioned by measuring the Time History Waveform of shaft under shaft starting condition.
