Abstract (en)
The lay-out has blade pins (2) crossing a case (4) and whose external portions are divided into two parts (15, 16) connected by an axial position adjustment unit (17) permitting to vary their length. The part (16) is removable from the pins and has a threaded end (18) in which a clamping nut (19) is engaged. The part (16) has a stopper (20) intended to control levers (10) that are tightened between the stopper and the nut.
Abstract (fr)
Les pivots (2) d'aubes (1) comprennent des portions amovibles (16) à leur extrémité extérieure dont la hauteur peut être réglée par un filetage (17) ou un moyen équivalent afin d'ajuster la distance entre la tête (9) d'un levier (10) de commande du calage de l'aube et le carter (4) ou la collerette (8) d'un palier (5) : si les douilles de centrage (7) des paliers (5 et 6) sont usées, les basculements néfastes des pivots (2) seront limités par un appui de butée de la tête (9). <IMAGE>
