Abstract

L'invention concerne un dispositif à engrenages comportant : un canal d'huile de lubrification (37) qui est ménagé au sein d'un boîtier (11) destiné à loger des engrenages (13a-13d); un moyen de distribution d'huile qui distribue de l'huile de lubrification (16) contenue au sein du boîtier (11) au canal d'huile de lubrification (37); et une section d'accumulation (39) qui est ménagée dans le canal d'huile de lubrification (37) et dans lequel s'accumulent les matières étrangères dans l'huile de lubrification (16) s'écoulant à travers le canal d'huile de lubrification (37). Une structure pour la capture des matières étrangères peut être simplifiée parce que les matières étrangères sont capturées en permettant aux matières étrangères de s'accumuler dans la section d'accumulation (39), et, par conséquent, le dispositif à engrenages possède une efficacité économique élevée. En outre, le dispositif à engrenages peut être extrêmement facile à entretenir parce que les matières étrangères accumulées dans la section d'accumulation (39) peuvent être facilement retirées par aspiration, ramassage ou essuyage.
