Crystal pulling device - with hollow seed crystal bar and coaxial sliding drive shaft (CS 15.9.78)

A crystal pulling device has a hollow bar carrying the seed crystal. A drive shaft enters the hollow bar coaxially leaving spaces for the circulation of a coolant. A sleeve, which is flanged to the hollow bar, carries a key which can slide in a keyway of the drive shaft to allow an axial motion comb...

Zusammenfassung:A crystal pulling device has a hollow bar carrying the seed crystal. A drive shaft enters the hollow bar coaxially leaving spaces for the circulation of a coolant. A sleeve, which is flanged to the hollow bar, carries a key which can slide in a keyway of the drive shaft to allow an axial motion combined with a rotary motion. This reduces the possible oscillations during the transmission of the rotation from the drive shaft to the seed crystal bar to a minimum. La dispositif comporte une tige creuse 8 avec porte-amorce 9 auquel est rapportée l'amorce 10. La commande de la tige creuse 8 comporte un arbre moteur 20 qui y est introduit coaxialement, ces tige 8 et arbre moteur 20 engrenant entre eux pour effectuer leur rotation en commun et des déplacements alternatifs de la tige solidairement avec un chariot 14, le long de l'axe longitudinal de l'arbre moteur 20. Ce dispositif permet d'obtenir des cristaux de haute qualité et de grandes dimensions.
