Title
(DE) GETRIEBE
(EN) GEARBOX
(FR) BOÎTE DE VITESSES
Abstract
(EN) Gearbox comprising a gearbox housing (2), a rotatable shaft (4), and a rolling bearing (6), via which said shaft is rotatably mounted in the gearbox housing. The outer ring (7) of the bearing is fitted in a bearing seat (11) arranged in the gearbox housing, wherein the outer ring of the bearing features, at a first axial end, a first edge surface abutting against a supporting surface in the bearing seat and, at an opposite second axial end, a second edge surface. A mounting plate (16) abuts against the second edge surface of the bearing's outer ring and is screwed onto the gearbox housing, in order to thus keep the outer ring of the bearing biased between the mounting plate and said supporting surface. A reservoir (25) for receipt of gearbox oil is arranged in the gearbox housing on the outside of and above the bearing seat, wherein the mounting plate forms an end wall (26) of such a reservoir. A groove (32) for leading gearbox oil from said reservoir into the bearing seat is arranged in the bearing seat.
(FR) L'invention concerne une boîte de vitesses comportant un carter de boîte de vitesses (2), un arbre tournant (4), et un palier à roulement (6), par le biais duquel ledit arbre est monté de manière rotative dans le carter de boîte de vitesses. La bague extérieure (7) du palier de roulement est adaptée dans une portée de roulement (11) agencée dans le carter de boîte de vitesses, dans lequel la bague extérieure du palier de roulement comporte, au niveau d'une première extrémité axiale, une première surface de bord venant prendre appui contre une surface de support dans la portée de roulement et, au niveau d'une deuxième extrémité axiale opposée, une deuxième surface de bord. Une plaque de montage (16) vient prendre appui contre la deuxième surface de bord de la bague extérieure du palier de roulement et est vissée sur le carter de boîte de vitesses, pour ainsi maintenir la bague extérieure sollicitée entre la plaque de montage et ladite surface de support. Un réservoir (25) permettant de recevoir de l'huile de boîte de vitesses est agencé dans le carter de boîte de vitesses sur l'extérieur de, et au-dessus de, la portée de roulement, la plaque de montage formant une paroi d'extrémité (26) d'un tel réservoir. Une rainure (32) permettant d'acheminer l'huile de boîte de vitesses depuis ledit réservoir jusque dans la portée de roulement est agencée dans la portée de roulement.
