Title
(EN) ADDITIVELY MANUFACTURED JOURNAL BEARING FOR A WIND TURBINE GEARBOX
(FR) PALIER LISSE FABRIQUÉ DE MANIÈRE ADDITIVE POUR UNE BOÎTE DE VITESSES DE TURBINE ÉOLIENNE
Abstract
(EN)
A method for manufacturing a gear assembly of a gearbox in a wind turbine includes providing a pin shaft of the gear assembly. The method also includes depositing material onto an exterior surface of the pin shaft of the gear assembly via an additive manufacturing process driven by a computer numerical control (CNC) device to form a bearing that circumferentially surrounds and adheres to the pin shaft. Further, the method includes providing a gear circumferentially around the bearing to form the gear assembly.
(FR)
La présente invention concerne un procédé de fabrication d'un ensemble engrenage d'une boîte de vitesses dans une turbine éolienne qui consiste à fournir un arbre de broche de l'ensemble engrenage. Le procédé consiste également à déposer un matériau sur une surface extérieure de l'arbre de broche de l'ensemble engrenage par l'intermédiaire d'un processus de fabrication additive entraîné par un dispositif de commande numérique par ordinateur (CNC) pour former un palier qui entoure l'arbre de broche de manière circonférentielle et y adhère. En outre, le procédé consiste à fournir un engrenage de manière circonférentielle autour du palier pour former l'ensemble engrenage.
