Abstract
An anti-wear device of a turbomachine rotor including a disk with a rim and axial recesses machined on the rim for the individual housing of blades; and a ring being fitted to one face of the rim, the ring being pierced with holes in the axial extension of the recesses, is disclosed. At least one of the holes in the extension of the recesses is closed by a plug including a metal head forming a bearing surface for the blades. The plug includes a stud in the extension of the metal head, an insert made of deformable material surrounding at least partly the stud, and a clamping device. The insert is made of deformable material being deformed by the clamping device so as to immobilize the plug in the hole.
