Abstract

Εις ένα μοντέλλον (1) ενός άξονος είναι διατεταγμένα μέσα στεγανώσεως (16) επί προεξεχόντων τμημάτων (2,3,4) τα οποία περιβάλλονται από ένα μεταλλικό καλούπι (8, 9, 10) ούτως ώστε το άνοιγμα μεταξύ αυτών (15) να είναι κλεισμένον εις την εισοδον κόκκων άμμου. Τοιουτοτρόπως επιτυγχάνεται τμηματικός περιορισμός των επιφανειακών ατελειών ή ελλαττωμάτων εις τον χυτευόμενο άξονα. ωIn a model (1) of a shaft, seals are arranged (16) on protruding parts (2,3,4) which are surrounded by a metal mold (8, 9, 10) so that the opening between them (15) is closed at the entrance of sand grains. In this way, a partial reduction of surface imperfections or defects in the molded shaft is achieved. ω
