Abstract

La présente invention concerne une unité de palier dans laquelle un arbre de turbine est supporté par un palier à roulement, un intérieur d'un palier est efficacement lubrifié par un lubrifiant à partir d'un trou d'huile tandis que la simplification d'un logement est obtenue. Dans un trajet d'huile (3) qui guide un lubrifiant à partir de l'extérieur d'un logement (1) dans lequel un arbre de turbine (100) est inséré à l'intérieur d'un palier d'un palier à roulement (2) supportant en rotation l'arbre de turbine (100) par rapport au logement (1), un trou d'huile (19) faisant face à une surface de contact de roulement d'un élément de roulement (10) à l'intérieur du palier dans une direction radiale est utilisé. Ainsi, une saillie pour le traitement du trou d'huile est rendue inutile dans le logement (1), et le lubrifiant à partir du trou d'huile (19) est directement fourni à l'élément de roulement (10) dans la direction radiale et exposé à une cage (11) pour être difficilement diffusé.
