METHOD OF REPAIRING OR REWORKING A TURBOMACHINE DISK AND REPAIRED OR REWORKED TURBOMACHINE DISK

摘要

The invention relates to a method for repairing or reworking a turbomachine disk comprising, on its rim, at least one exterior radial tab with an axial bore to accommodate an axial stud comprising a head and a shank with a threaded portion, the stud being slipped into the bore in such a way that the head presses against one face of the tab by the tightening of a nut on the threaded shank portion against the opposite face of the tab, the said stud forming a means of keeping a tab secured to a part attached to the rim. It is characterized in that a counterbore (123B; 223B; 323B) is machined in the tab around the bore (123A; 223A; 323A) corresponding to the wearing zone, and a replacement stud (100) that has a flange (111A) is fitted bearing against the surface of the said counterbore, of a diameter greater than that of the head (111).
