Abstract
A wind turbine gearbox, in particular planetary gearbox, has at least one gear which is mounted on an axle, wherein a sliding surface is arranged between the gear and the axle. The sliding surface is arranged on at least one layer of a deposition welded material made from a sliding bearing material. Furthermore, a method produces the wind turbine gearbox.
Claims18
A wind turbine gearbox having at least one gear which is mounted on an axle, wherein a sliding surface is arranged between the gear and the axle or between the axle and an axle holder, wherein the sliding surface is arranged on at least one layer of a deposition welded material made of a sliding bearing material, and wherein the layer of the deposition welded material is applied directly to an outer shell surface of the axle.
A method for producing a wind turbine gearbox, having at least one gear which is mounted on an axle, wherein a sliding surface is arranged between the gear and the axle, wherein the method comprises the following steps:
- providing the axle;
- deposition welding of a sliding bearing material and with that, depositing a layer of a deposition welded material directly onto the axle;
- forming the sliding surface on the layer.
A wind turbine gearbox having at least one gear which is mounted on an axle, wherein a sliding surface is arranged between the gear and the axle or between the axle and an axle holder, wherein the sliding surface is arranged on at least one layer of a deposition welded material made of a sliding bearing material, and wherein the gear is designed as a planetary gear.
A wind turbine gearbox having at least one gear which is mounted on an axle, wherein a sliding surface is arranged between the gear and the axle or between the axle and an axle holder, wherein the sliding surface is arranged on at least one layer of a deposition welded material made of a sliding bearing material, and wherein the deposition welded material consists of or comprises a material selected from a group comprising aluminum base alloys, tin base alloys, bronze base alloys, brass base alloys.
