Title (EN) FIXED-SHAFT HELICAL DRUM STRUCTURE WITH THE SHAFT SUPPORTED AT BOTH ENDS
(FR) STRUCTURE DE TAMBOUR A AXE FIXE DANS LEQUEL L'AXE EST SUPPORTE AUX DEUX EXTREMITES
Abstract:
(EN) A drum assembly for a helical scan recorder comprises a stationary first drum and a shaft having a shaft first end centrally mounted to the first drum and a shaft second end. The drum assembly further comprises a rotatable second drum which has at least one transducing element mounted thereon. The shaft extends axially through the second drum and the shaft second end protrudes axially above the second drum. The drum assembly also comprises a physical support member connected to the first drum. The physical support member is connected to the first drum and also connected to stabilize the shaft second end while allowing rotation of the second drum. The physical support member is connected to the shaft second end to reduce deflection of the shaft second end when the drum assembly is exposed to external vibration or shock.
(FR) Un ensemble tambour (20, 20(7)) destiné à un enregistreur à balayage hélicoïdal comprend un premier tambour fixe (22) et un axe (24) présentant une première extrémité (26) installée au centre sur le premier tambour et une deuxième extrémité (28). L'ensemble tambour comprend également un deuxième tambour rotatif (32) qui comporte au moins un élément transducteur (34) installé sur ce dernier. L'axe (24) s'étend axialement dans le deuxième tambour (32) et la deuxième extrémité (28) de l'axe dépasse axialement au-dessus du deuxième tambour (32). L'ensemble tambour comprend également un élément de support physique (40, 40(7)) couplé au premier tambour (22). L'élément de support physique (40, 40(7)) est relié au premier tambour (22) mais également couplé pour stabiliser la deuxième extrémité (28) de l'axe tout en permettant au deuxième tambour (32) de tourner. L'élément de support physique (40, 40(7)) est couplé à la deuxième extrémité (28) de l'axe en vue de réduire la déflexion de la deuxième extrémité (28) de l'axe lorsque l'ensemble tambour est exposé à une vibration ou un choc venant de l'extérieur.
