  • the central shaft is mounted in automatic transmissions but also in conventional or automated manual transmissions of motor vehicles between the end-side main bearings in several additional guide bearings to absorb imbalances and forces from their rotational movement can. Since the radial space for such a guide bearing within the transmission, however, is extremely limited, these bearings are currently mainly sliding bearings are used, which with an inner diameter between 15 mm and 50 mm and a bearing width between 8 mm and 20 mm maximum radial height of 1, 7 mm and are usually designed as a composite sliding bearing with a carrier tape made of steel or bronze and a porous bronze sintered frame.

Abstract

L'invention concerne une douille à aiguilles (1) avec un anneau externe (4) à fines parois pouvant être intégré, qui présente sur ses côtés axiaux deux bordures (5, 6) orientées radialement vers l'intérieur et composé d'une couronne d'aiguilles (7) maintenue dans l'anneau externe par ces bordures. La couronne d'aiguilles est formée par une cage à aiguilles (8) et une pluralité d'aiguilles de roulement (9) placées à l'intérieur à espacements réguliers dans le sens de la circonférence. Selon l'invention, avec un diamètre de cercle inscrit correspondant au diamètre externe de l'arbre à soutenir compris entre 15 mm et 50 mm et avec une largeur de palier correspondant à l'écart externe de ses bordures compris entre 8 mm et 20 mm, la douille à aiguille présente d'une part uniquement une hauteur de construction radiale de 1,5 mm maximum et d'autre part, son anneau externe, sa cage à aiguilles, ses aiguilles de palier sont fabriqués sans enlèvement à partir d'un matériau tel que celle-ci peut être échangée avec un palier lisse utilisé à des températures de service de - 40 °C à au moins + 140 °C, ainsi qu'à des régimes de fonctionnement pouvant atteindre 7000 min-1, avec une hauteur de construction radiale identique, un diamètre interne identique et une largeur de palier identique, sans modifier la construction qui l'entoure.
