Abstract

Système de palier radial à butée à deux paliers hydrostatiques (3, 4) radiaux à butée, mobiles dans le sens axial par rapport à un logement (2) de palier qui les entoure. Chaque palier radial à butée comprend une bride (5, 6) reliée à l'axe (1). La bride comprend une surface d'appui (5a, 6a) et un palier (7, 8) de chambre de rondelle pourvu d'une surface (7a, 8a) opposée à la surface d'appui (5a, 6a), dans laquelle se trouve une gorge (7b, 8b) de rondelle, la surface (7a, 8a) et la surface d'appui (5a, 6a) formant ensemble des fentes de serrage interne et externe de chaque côté de la gorge de rondelle. La surface d'appui et la rondelle forment ensemble une chambre (7b, 8b) de rondelle dans laquelle un fluide hydraulique est introduit sous pression à partir d'une source de fluide hydraulique. Le palier (7, 8) de la chambre de rondelle constitue, avec le logement (2) de palier, une chambre (13, 14) qui est soumise à une pression hydraulique et qui comprime le palier (7, 8) de la chambre de rondelle (7, 8) contre la surface d'appui (5a, 6a), les deux paliers (7, 8) de chambre de rondelle étant comprimés dans des directions réciproquement opposées. Un moyen, tel qu'une soupape pilote (17), est agencé de façon à agir conjointement avec un émetteur/détecteur (21) servant à détecter la position de l'axe (1) par rapport au logement (2) de palier, afind de réguler la quantité de fluide hydraulique alimentant la chambre de rondelle respective (13, 14) ainsi que la pression hydraulique agissant sur le palier respectif (3, 4), ce qui permet à des charges d'importance variable d'être appliquées dans des directions variables sur l'axe (1) tandis que l'aptitude de déplacement axial de ce dernier est maintenue. Au moins une bride (5, 6) peut être démontée de l'axe (1), et les surfaces d'appui (5a, 6a) sont orientées dans des directions opposées, chacune formant un angle principalement non perpendiculaire par rapport à l'axe (1).
