摘要： A hydrodynamic bearing assembly (30) includes a bearing sleeve (10) defining at least an open end therein (14); a shaft (20) rotatably disposed in the bearing sleeve; lubricant (40) filled in a bearing clearance (11) formed between an outer face (21) of the shaft and an inner face (12) of the bearing sleeve; and a leakage-preventing band disposed at the open end of the bearing sleeve. An outer face of the shaft defines a plurality of lubricant pressure generating grooves (17) straightly along an axial direction thereof for generation of hydrodynamic pressure of the lubricant. Each groove has a depth gradually decreased along a rotation direction of the shaft.
