Title (EN) IMPROVED PLANET CARRIER.
(FR) PORTE-SATELLITES AMÉLIORÉ
Abstract:
(EN) A planet carrier comprises a plurality of planet axles suspended in-between a first carrying wall and a second carrying wall (22). The second carrying wall (22) has a plurality of stiffness-reducing slot-shaped interruptions (7A, 7B, 7C) corresponding to a plurality of second planet axle receiving areas (32A, 32B, 32C). Each of the stiffness-reducing slot-shaped interruptions has a curved longitudinal slot direction having a U-shaped form which envelopes a planetary central rotation axis (4A, 4B, 4C). Thanks to these special stiffness-reducing slot-shaped interruptions, improved mutual balancing of the stiffnesses of both carrying walls is obtained. This results into improved gear meshing under load.
(FR) L'invention concerne un porte-satellites comprenant une pluralité de ponts planétaires suspendus entre une première paroi porteuse et une deuxième paroi porteuse (22). La deuxième paroi porteuse (22) comporte une pluralité d'interruptions en forme de fente (7A, 7B, 7C) réduisant la rigidité qui correspondent à une pluralité de deuxièmes zones de réception de pont planétaire (32A, 32B, 32C). Chacune des interruptions en forme de fente réduisant la rigidité a une direction de fente longitudinale curviligne ayant une forme en U qui enveloppe un axe de rotation central planétaire (4A, 4B, 4C). Ces interruptions en forme de fente réduisant la rigidité spéciales permettent d'obtenir un équilibrage mutuel amélioré des raideurs des deux parois porteuses. Il en résulte un engrenage amélioré qui s'engrène en charge.
