Abstract

L'invention concerne un arbre pour centrifugeuse. Elle se rapporte à un arbre qui comprend un fût 32 ayant deux parties de raccordement 34 et 36 au rotor de centrifugeuse et à l'arbre 38 du moteur respectivement, l'arbre 32 étant entouré par une broche 40 qui assure la fixation du fût sur l'arbre 38 du moteur, et par un manchon 50 qui entoure la broche sur une grande partie de sa longueur. De cette manière, le fût 32 ne peut pas subir un fléchissement latéral trop important. Application aux centrifugeuses de laboratoires.
