Claims (10)

  1. Transmission à palier rotatif (15) contenant un arbre principal (11), un logement de palier principal (6) dans lequel ledit arbre principal (11) est supporté sur des coussinets (12), un arbre secondaire (13) relié à l'arbre principal (11) et effectuant des rotations autour de l'axe géométrique (7) de l'arbre principal (11), dont l'axe géométrique (14) est parallèle à, mais en excentricité par rapport à l'axe géométrique (7) de l'arbre principal (11), ainsi qu'un logement de palier rotatif (16) dans lequel l'arbre secondaire (13) effectuant des rotations conjointement avec le logement de palier (16) est supporté sur le palier rotatif (15) de façon à effectuer des rotations autour de son axe géométrique, caractérisée en ce que la transmission contient un joint étanche (17; 22, 23) qui est situé entre le côté interne du logement de palier principal (6) et le côté externe du logement de palier rotatif (16), procure une étanchéité à l'ouverture entre ces logements de paliers (6 et 16) et est fixe par rapport à l'ensemble constitué par l'arbre principal (11) et par l'arbre secondaire (12).
  2. Transmission selon la revendication ci-dessus, caractérisée en ce que le joint étanche (17; 22, 23) contient un anneau (17, 22) qui est fixé sur une partie (19) faisant saillie en direction radiale, qui s'étend dans ou qui est opposée à l'ouverture entre le côté interne du logement de palier principal (6) et le côté externe du logement de palier rotatif (16), et qui s'appuie sur l'ensemble constitué par l'arbre principal (11) et par l'arbre secondaire (13).
  3. Transmission selon l'une quelconque des revendications ci-dessus, caractérisée en ce qu'on prévoit un filet de vis (20) sur un des côtés formés par le côté interne du logement de palier principal (6) opposé au joint étanche (17; 22, 23) et par le côté externe opposé du joint étanche (17; 22, 23).
  4. Transmission selon l'une quelconque des revendications ci-dessus, caractérisée en ce qu'on prévoit un filet de vis (20) sur un des côtés formés par le côté externe du logement de palier rotatif (16) opposé au joint étanche (17; 22, 23) et par le côté interne opposé du joint étanche (17).
  5. Transmission selon les revendications 3 et 4, caractérisée en ce que le joint étanche (17) est muni d'un filet de vis (20) à la fois sur le côté interne opposé au logement de palier rotatif (16) et sur le côté externe opposé au logement de palier principal (6).
  6. Transmission selon l'une quelconque des revendications 3 et 4, caractérisée en ce que le logement de palier (6, 16) est muni d'un filet de vis (20) opposé au joint étanche (17; 22, 23).
  7. Transmission selon la revendication ci-dessus, caractérisée en ce que le filet de vis (20) est prévu dans un logement de palier (6, 16) dans une pièce rapportée annulaire (21) qui est encastrée sur le côté du joint étanche (17; 22, 23) dans le logement de palier.
  8. Transmission selon la revendication 2, caractérisée en ce que le joint étanche (22, 23) contient une lèvre d'étanchéification (23) qui est prévue sur un des côtés formés par le côté interne du logement de palier principal (6) opposé à l'anneau (22) et par le côté externe opposé de l'anneau (22).
  9. Transmission selon l'une quelconque des revendications 2 et 8, caractérisée en ce que le joint étanche (22, 23) contient une lèvre d'étanchéification (23) qui est prévue sur un des côtés formés par le côté externe du logement de palier rotatif (16) opposé à l'anneau (22) et par le côté interne opposé de l'anneau (22).
  10. Joint étanche pour conférer une étanchéité à l'ouverture entre un logement de palier principal (6) dans lequel un arbre principal (11) est supporté sur des coussinets (12) et un logement de palier mobile (16) se déplaçant à l'intérieur dudit logement de palier principal en suivant une trajectoire circulaire, dans lequel un arbre secondaire (13) est supporté par un palier (15), caractérisé en ce qu'il contient un anneau (17, 22) dont la largeur augmente depuis un minimum à un endroit jusqu'à un maximum à un endroit diamétralement opposé.
