Estimating the term…
The invention concerns a method for transverse ultrasound peening of blades (2) on a rotor which consists in driving in rotation the wheel (3) bearing the blades (2) about its geometrical axis (6) arranged substantially vertically and in causing the blades (2) to pass through a mist of microbeads produced by a vibrating surface (20) in an active chamber (12) arranged laterally relative to the wheel. The active surface (20) is located beneath the path of the blades (2). Preferably, the active chamber (12) comprises a second vibrating surface above the path of the blades (2). The invention also concerns a machine for implementing said method.
A method for the ultrasonic peening of parts (2) lying radially at the periphery of a wheel (3), according to which method the wheel (3) is set in rotation about its geometric axis (6) and a mist of microbeads (15) is created in a fixed active chamber (12) arranged to the side of said wheel (3), by means of a first vibrating surface (20) arranged in the lower part of said active chamber (12), said active chamber (12) comprising an opening shaped to allow the parts (2) to be put in and removed as the wheel (3) rotates and being sized to accommodate at least three adjacent parts, characterized in that the wheel (3) is rotated about a roughly vertical axis (6) and in that the first vibrating surface (20) is arranged under the path of the parts in the active chamber (12).
