Abstract: front page image
(EN)An improved centrifugal machine as shown in Figure 1, includes a buffer system as shown in Figure 2, for resisting gyration of the bearing housing, spindle (18) and basket (22). Elastic ring (232) exerts a force in the direction of axis A when compressed between the base (228) of the channel (226) and the radial abutment surface (220). Compression of the elastic ring (232) between the radial abutment surface and the base (228) of the channel and the frictional restoring force between the ball (100) and socket (102) may be adjusted by means of the bolts (222). Radial compression force exerted by the elastic ring (258) between the base (250) and axial abutment surface (234) may be adjusted by positioning the flange member (254). Adjustment of the pressure exerted by elastic ring (258) in the radial direction may be done independently of adjustment of the pressure exerted by the first elastic ring (232) in the axial direction. The improved centrifugal machine further includes a sensing system as shown in Figure 3 and Figure 4, for detecting when such gyration becomes excessive and for then discontinuing driving of the spindle (18) and basket (22) by the motor 12). The cap (332) is threaded to a position on the end (330) of the rod (314) so that a gap of 0.01 inch exists between the end of the cap and the switch button (340) of a microswitch (338). Thereby, the system may be set to discontinue operation of the basket (22) at different selectable degrees of gyration.
(FR)Centrifugeuse amelioree telle qu"illustree en Fig. 1 qui comprend un systeme tampon tel qu"illustre en Fig. 2, pour resister a la giration du logement de palier, de l"axe (18) et du panier (22). Un anneau elastique (232) exerce une force dans la direction de l"axe A lorsqu"il est comprime entre la base (228) du canal (226) et la surface de butee radiale (220). La compression de l"anneau elastique (232) entre la surface de butee radiale et la base (228) du canal et la force de friction de restitution entre la rotule (100) et la calotte (102) peut etre ajustee au moyen de boulons (222). La force de compression radiale exercee par l"anneau elastique (258) entre la base (250) et la surface d"appui axiale (234) peut etre ajustee par le reglage de la position de la piece de bride (254). L"ajustement de la pression exercee par l"anneau elastique (258) dans la direction radiale peut etre effectue independamment de l"ajustement de la pression exercee par le premier anneau elastique (232) dans la direction axiale. La centrifugeuse amelioree comprend de plus un systeme de detection tel qu"illustre en Figs. 3 et 4, permettant de detecter si la giration devient excessive et arre, er l"entrainement de l"axe (18) et du panier (22) par le moteur (12). Le chapeau (332) est filete en une position sur l"extremite (330) de l"axe (314) afin qu"un intervalle de 0,25 cm. existe entre l"extremite du chapeau et le bouton de commutation (340) d"un microcommutateur (338). Ainsi le systeme peut etre ajuste pour faire cesser le fonctionnement du panier a des degres selectionnes de giration.
