Abstract: The present invention relates to a wind turbine generator comprising a gearbox, wherein said gearbox comprises a planetary gear system, wherein said planetary gear system comprises a carrier assembly, wherein said carrier assembly comprises a carrier supporting at least one planetary gear that is rotatably mounted through a bearing on a shaft, wherein the shaft is fixed in a bore defined by the carrier. The carrier assembly includes interlocking means to prevent angular movement of the shaft relative to the bore. This improves the robustness of the coupling between the shaft and the bore of the carrier.

Abstract: A method 400 of predicting tonal noise produced by a wind turbine is disclosed. The method comprises acquiring 410 a first set of vibration data, the first set of vibration data being from a plurality of vibration sensors positioned at different locations about a wind turbine drivetrain when the wind turbine drivetrain is undergoing testing in a test rig; acquiring 420 a second set of vibration data, the second set of vibration data being from a plurality of vibration sensors positioned at different locations about the same or a similar wind turbine drivetrain when located in a wind turbine; acquiring 430 noise data including tonal noise produced by the wind turbine; identifying 440 a vibration sensor of interest using vibration data of the second set of vibration data and the noise data; determining 450, for the identified sensor, a first relationship between vibration data of the first set of vibration data and the second set of vibration data; and determining 460, for the identified vibration sensors, a second relationship between the first set of vibration data and tonal noise produced by a wind turbine based on the first relationship.
