| Abstract: | the temperature of the fluid film rises significantly as the frictional heat in herringbone grooved journal bearings,thereby the viscosity of the fluid and the clearance of hydrodynamic bearings decrease.In this article,the thermal expansion of the sleeve's inner radius was determined by LUO Zai's method.It shows that the variation of clearance is an important design consideration which affects the dynamic characteristics of the hydrodynamic bearing of a HDD spindle motor. |
| Keywords: | herringbone grooved journal bearings thermo-hydrodynamic analysis stability characteristics |
