Method and apparatus for ultrasonic peening of axial recesses for the attachment of blades to a rotor |
摘要 |
The invention relates to an apparatus and to a method for the surface treatment and compressive prestressing by peening of a wall of at least one oblong cavity formed in a part, said cavity opening to the outside via a lateral mouth and having two ends presenting frontal openings. The wall of the cavity is ultrasonically peened by mobilizing a plurality of beads in a chamber delimited by said wall of said cavity, a vibratory surface closing off said mouth of said cavity, and closing-off means closing off said openings, by means of a sonotrode excited by means for producing ultrasonic oscillations. The method and the apparatus are particularly intended for treating a turbine disk comprising a number of axial recesses formed in the periphery of said disk and having wall portions which diverge from each mouth.
