Guide bearing structure for reducing oil mist of hydro-generator

The invention discloses a guide bearing structure for reducing oil mist of a hydro-generator, and relates to the field of generators. The structure comprises a bearing and a bearing oil tank, and oleophobic layers or super-oleophobic layers cover the wall surface of an oil baffle pipe, the wall surface of an oil baffle plate, a shaft collar and the inner wall of an oil tank in the bearing oil tank; under the action of the oleophobic layers or the super-oleophobic layers, the friction force between a turbine and the wall surface of the oil baffle pipe, the wall surface of the oil baffle plate,the shaft collar or the inner wall of the oil tank is reduced to achieve the purposes of reducing the temperature of lubricating oil and reducing oil mist evaporation; and meanwhile, the friction resistance of the contact area of the shaft collar and the lubricating oil is reduced, the fluctuation of the oil level in the bearing oil tank is reduced, the surge of the oil level is reduced, the contact area of the lubricatin
