| 摘要 |
The present invention relates to a method for repairing a flange (43) of a rotor, to the transverse surface of which a disk (20) of a fan in an upstream turbo-fan engine is attached. The flange comprises, in the form of a ring, openings (43F) for connecting to the disk (20) and intermediate, so-called discharge openings (43D). Wear marks (T) are formed by the friction of the fan blades on the flange. The method includes a step of machining spot facings (43) onto the flange, in the areas with wear marks, and placing so-called anti-wear slugs (50, 150) in the discharge openings (43D) that can be covered by the blades during friction. The method is characterized in that the spot facings (43L) extend between the connection openings (43D) and are circumferentially limited by the clamping surfaces of the connection between the disk and the flange. |
