The present invention relates to a high-pressure blower. Especially, the technical objective of the present invention is to provide a bearing babbitt bush for high-pressure blower and a high-pressure blower using the same, which allows oil return holes capable of discharging, to the outside of the bearing babbitt bush, oil flowing into the surface of the inner circumference of the bearing babbitt bush to communicate with an oil discharging groove formed on the inner circumference of the bearing babbitt bush. To this end, the bearing babbitt bush for high-pressure blower according to the present invention, comprises: a main body unit which is mounted to a first side hole of an oil box formed a first side surface of the oil box being in contact with a housing, among surfaces of the oil box for high-pressure blower which comprises the housing, the oil box, a rotating part, and a connecting shaft, covers the outer circumference of the connecting shaft passing through the first side hole of the oil box, and has a hollow cylindrical shape; an oil collecting groove which is formed on the inner circumference of the main body unit to collect oil flowing into along the inner circumference; at least five oil return holes which pass through a first side of the main body unit to be connected to the oil collecting groove in the lower end of the first side of the main body unit being in contact with a first side surface of the oil box among the side surfaces of the main body unit, wherein the oil return holes are formed to have an angle within the range of 10 to 30 degrees for the virtual axis of rotation of the main body unit. |
