Process for the manufacture of a rotor for shafts of electric motors, and apparatus for the execution of the process.

摘要

A process and an apparatus are described for the manufacture of a rotor, and in particular of a fan intended to be keyed to a shaft. An axial insertion elastic ring is included in the hub of the rotor, obtained by molding, and means are provided in the mold which are adapted to fix the elastic retaining ring during molding in the position it will assume on the shaft, keeping the ring free to exert a radial locking pressure on said shaft at the end of the molding.
