A lubrication device for lubricating a shaft bearing in a turbojet, the device comprising:
- an annular component support part mounted on stationary elements and defining a lubrication chamber around the shaft bearing;
- and
- an annular cover including an oil inlet for lubricating the shaft bearing, the annular cover having a radial end face mounted in a sealed manner on a radial end face of said annular support part, sealing being provided by an annular gasket mounted between the support part and the cover, said cover including an annular enclosure for feeding pressurizing and cooling air, the enclosure is fed at its upstream end by ducts formed through the support part and having their downstream ends opening out around the annular gasket, wherein
- the device includes means for providing a flow of pressurizing and cooling air between the radial end face of the support part and the radial end face of said cover around said annular gasket.
A lubrication device, comprising:
- an annular component support part having a radial end face and defining a lubrication chamber around a component;
- an annular cover having a radial end face disposed to the radial end face of the annular support part, the annular cover including
- an inlet configured to lubricate the component, and
- an annular enclosure configured to feed air;
- an annular gasket configured to seal the annular component support part and the annular cover;
- and
- an annular channel configured to provide a flow of the air around the annular gasket.
