Abstract

L'invention concerne le génie mécanique et notamment des moteurs / variateurs destinés aux entraînements à commande automatique et/ou forcée. Le variateur planétaire à disque de l'invention comprend des disques de frottement externes, fixés sur le corps, et des disques de frottement internes centraux, fixés sur un arbre d'entrée. Ils entrent en contact avec des disques de frottement intermédiaires coniques (des satellites), monté rotatifs sur des leviers pivotants montés sur un bras porte-train pivotant. Les extrémités opposées des leviers sont dotés de rouleaux poussoirs qui roulent sur les surfaces de travail des orifices profilés d'une articulation de réglage, reliée à l'arbre de sortie du variateur. Les leviers pivotants sont précontraints par ressorts par rapporta au bras porte-train, de manière à ce que les satellites, sous l'action des ressorts, soient dirigés vers le centre du variateur en réduisant le rapport de transmission; ils sont reliés avec une douille qui se déplace le long de l'axe longitudinal du variateur, sans possibilité de pivoter autour de cet axe, au moyens de liaisons mécaniques transformant le pivotement des leviers pivotants sur le bras porte-train rotatif en un déplacement axial de la douille. La douille est entraînée par un mécanisme à leviers relié à l'entraînement de commande dudit mécanisme à leviers. L'invention permet d'élargir le domaine d'utilisation du variateur.
