FLUID HYDRODYNAMIC BEARING ASSEMBLY, CAPABLE OF PREVENTING A SHAFT FROM BEING OVER RISEN BY A THRUST MEMBER OF A CONICAL SHAPE

摘要

PURPOSE: A fluid hydrodynamic bearing assembly is provided to enable to increase a bonding force of a shaft and a thrust member and to reduce damage of the thrust member when impact is applied from outside.;CONSTITUTION: A fluid hydrodynamic bearing assembly(100) comprises a shaft(110), a sleeve(120), a thrust member(130), and a cover member(140). The sleeve supports the shaft to be rotatable. The thrust member is installed in the lower part of the shaft and formed into a conical shape. The cover member is installed in the lower part of the sleeve, thereby preventing a leakage of lubricating fluid. The top of the cover member and the bottom of the thrust are formed to be flattened in order to prevent the generation of dynamic pressure caused by a dynamic pressure groove when the shaft rotates.;COPYRIGHT KIPO 2013
