Title (EN) PLANET CARRIER OF A WIND TURBINE GEARBOX WITH IMPROVED LUBRICANT PATH
(FR) PORTE-SATELLITES D'UNE BOÎTE DE VITESSES D'ÉOLIENNE À CIRCUIT DE LUBRIFIANT AMÉLIORÉ
Abstract:
(EN) A gearbox assembly includes a gearbox housing (137) and a planetary gear system (138) configured within the gearbox housing. The planetary gear system includes a plurality of planet gears (144), at least one sun gear (146), at least one ring gear (141), at least one planetary carrier (142) operatively coupled with the plurality of planet gears, and a plurality of pin shafts (143, 145). Each of the plurality of planet gears are arranged so as to rotate around one of the plurality of pin shafts. Further, the plurality of planet gears are engaged with the ring gear and configured to rotate about the sun gear. The gearbox assembly also includes a first lubricant path (150) defined from a first location to a second location through the at least one planetary carrier. Moreover, the first lubricant path is located outside of the plurality of pin shafts.
(FR) L'invention concerne un ensemble boîte de vitesses comprenant un carter (137) de boîte de vitesses et un train planétaire (138) conçu à l'intérieur du carter de boîte de vitesses. Le train planétaire comprend une pluralité de satellites (144), au moins une roue solaire (146), au moins une couronne (141), au moins un porte-satellites (142) accouplé fonctionnellement à la pluralité de satellites, et comprend une pluralité de tiges (143, 145). Chaque satellite parmi la pluralité de satellites est agencé de façon à tourner autour d'une tige parmi la pluralité de tiges. En outre, les multiples satellites s'engrènent avec la couronne et sont conçus pour tourner autour de la roue solaire. L'ensemble boîte de vitesses comprend également un premier circuit de lubrifiant (150) délimité à partir d'un premier emplacement vers un second emplacement à travers ledit porte-satellites. De plus, le premier circuit de lubrifiant se trouve à l'extérieur de la pluralité de tiges.
