Beschreibung
Zusammenfassung:	A combination of a hydrodynamic bearing and a wing plate includes the hydrodynamic bearing, a rotating shaft and the wing plate. The rotating shaft is disposed on the wing plate, and is inserted into a shaft hole of the hydrodynamic bearing. An inner wall of the shaft hole of the hydrodynamic bearing is provided with at least two oil-guiding groove sets, each oil-guiding groove set includes a plurality of oil-guiding grooves, and a cusps is formed at the bend of each oil-guiding groove. The cusps of the oil-guiding grooves of the same oil-guiding groove set forms a corresponding cusp point arranged along the circumferential direction in the shaft hole. An active area is formed between the corresponding cusps of each adjacent two oil-guiding groove sets in the shaft hole, and a mass center of the wing plate and the rotating shaft is in or close to the active area. Therefore, the hydrodynamic bearing has better supporting force that can support the balanced rotation of the rotating shaft and the wing plate, and
