Ultrasound transverse grit blasting of rotor blades comprises rotating wheel carrying blades which pass through micro ball mist maintained by vibrating surface in enclosure

摘要

A method, and machine for implementing the method, for transverse ultrasound peening of blades on a rotor that drives in rotation a wheel bearing the blades about its geometrical axis arranged substantially vertically and causes the blades to pass through a mist of microbeads produced by a vibrating surface in an active chamber arranged laterally relative to the wheel. The active surface is located beneath the path of the blades. Preferably, the active chamber includes a second vibrating surface above the path of the blades.
