  • Process for manufacturing an impeller
    Patent number: 6416285
    Abstract: A method for producing a rotor of a fan, which has support disks and lamellae which each have a curved cross-sectional profile, is proposed. The method is distinguished by the fact that firstly the lamellae are pushed axially into receiving openings in the support disks. Then, the profile height of each lamella is increased as a result of the lamella being plastically deformed in the region of the receiving opening, in such a manner that the lamella becomes clamped in its receiving opening.
