Abstract

Goulotte de lubrification d'un train d'engrenages (la, 6 ; lb, 7; 1c, 8; 1d, 9; le, 10 ; 1f, 11) de boîte de vitesses en rotation dans un carter étanche de mécanisme et de différentiel, formant dans sa partie inférieure un réservoir de lubrifiant où est immergé le bas de la couronne (4a) du différentiel de sorte que sa rotation provoque l'élévation et la projection de lubrifiant en direction de la goulotte (5) qui capte le lubrifiant projeté et la distribue sur les zones à lubrifier (5b) du train d'engrenages, caractérisée en ce que la zone de captation de la goulotte est déportée au-delà du point haut de la couronne de différentiel par rapport au train d'engrenages lubrifié (la, 6 ; lb, 7; 1c, 8; 1d, 9; le, 10 ; 1f, 11).Lubrication channel of a gear train (1a, 6; 1b, 7; 1c, 8; 1d, 9; 1a, 10; 1f, 11) of a rotational gearbox in a gear and differential housing , forming in its lower part a lubricant reservoir which is immersed the bottom of the ring (4a) of the differential so that its rotation causes the elevation and projection of lubricant towards the chute (5) which captures the projected lubricant and distributes it on the areas to be lubricated (5b) of the gear train, characterized in that the catch area of the chute is offset beyond the high point of the ring gear with respect to the lubricated gear train ( la, 6; 1b, 7; 1c, 8; 1d, 9; 1a, 10; 1f, 11).
