description A method for manufacturing a pitch bearing or a yaw bearing for a wind turbine includes forming an outer race of the bearing of a base material. The method also includes forming an inner race of the bearing of the base material. Further, one of the inner race or the outer race defines a circumferential surface comprising a plurality of gear teeth. The method further includes arranging the inner race within the outer race. In addition, the method includes providing a plurality of roller elements between the outer and inner races. Moreover, the method includes applying a coating material to at least a portion of the plurality of gear teeth via an additive manufacturing process. The coating material is different than the base material. As such, the coating material provides at least one of increased hardness, strength, or durability to the base material. La présente invention concerne un procédé de fabrication d'un palier de tangage ou d'un palier de lacet pour une éolienne comprenant la formation d'un chemin de roulement extérieur du palier à partir d'un matériau de base. Le procédé comprend également la formation d'un chemin de roulement intérieur du palier du matériau de base. En outre, un chemin parmi le chemin de roulement intérieur et le chemin de roulement extérieur définit une surface circonférentielle comprenant une pluralité de dents d'engrenage. Le procédé comprend en outre l'agencement du chemin de roulement intérieur à l'intérieur du chemin de roulement extérieur. De plus, le procédé comprend la fourniture d'une pluralité d'éléments de rouleau entre les chemins de roulement extérieur et intérieur. De plus, le procédé comprend l'application d'un matériau de revêtement sur au moins une partie de la pluralité de dents d'engrenage par l'intermédiaire d'un processus de fabrication additive. Le matériau de revêtement est différent du matériau de base. En tant que tel, le matériau de revêtement fournit au moins propriété accrue, parmi une dureté, une résistance ou une durabilité au matériau de base.
