The anti-vibration device (10) for the machining of a shaft (30) comprises a first fixed ring intended to be kept inside a shaft (30) by means of a shoulder (17), said anti-vibration device comprising: • at least one first external groove (12) and at least one first external seal (121) for forming at least one contact with the internal surface of the shaft (30); • at least one first internal circumferential groove (11) and at least one first internal seal (110) for forming at least one contact with the external surface of the bar (30); • an internal circumferential cavity (18) that is able to cause the circulation of a fluid (122) arriving through a first duct (14, 16) and leaving through a second duct (13, 15), said first duct (14, 16) and second duct (13, 15) passing through the radial thickness of the anti-vibration device (10), the internal circumferential cavity (18) making it possible to realize a vibration-damping function when a fluid (122) passes through it. |
