Zusammenfassung:	An upper frame oil mist preventing structure of a hydrogenerator is disclosed. Labyrinth pieces arranged at intervals are disposed within the air vent window of the upper frame; the pitch of the labyrinth pieces is 10 mm; and there are not less than 20 labyrinth pieces. The bearing cap and the thrust collar of the upper frame are sealed through stuffing arranged therebetween. An inclined air vent is formed on the thrust collar of the upper frame; and a damping groove is formed on the inner wall of the thrust head. Two layers of oil baffle pipes are arranged on the upper frame. Besides, the upper frame is provided with an oil baffle plate inserted between the two layers of oil baffle pipes. The upper frame oil mist preventing structure of the hydrogenerator has the advantages of eliminating internal and external oil throwing of the upper frame of the high-speed hydrogenerator and keeping the workshop building of a power station tidy.
