Abstract

Dispositif de lubrification d’une ligne d’arbres (2, 4) de boîte de vitesses comprenant au moins un arbre (4) à l’intérieur duquel est ménagé un perçage axial (7) d’écoulement d’huile et plusieurs perçages (8a, 8b, 8c) partant radialement de celui-ci au droit de zones de lubrification ciblées de la boîte, caractérisé en ce qu’il comporte une canule tournante (11) disposée en amont des zones de lubrification ciblées, dans le flux d’écoulement d’huile à l’intérieur de la ligne d’arbres. Figure pour l’abrégé : figure 2Device for lubricating a line of gearbox shafts (2, 4) comprising at least one shaft (4) inside which is provided an axial bore (7) for the flow of oil and several bores ( 8a, 8b, 8c) starting radially from the latter in line with targeted lubrication zones of the box, characterized in that it comprises a rotating nozzle (11) arranged upstream of the targeted lubrication zones, in the flow of oil flow inside the tree line.
