    Abstract: A power transmission system 10 of a wind turbine has a main shaft 16 configured to be driven by the rotor 6 and a support structure 60, a gearbox 25 having a gearbox housing 24,30 rigidly coupled to the support structure 60 and a planet carrier 26. A coupling member 50 connects the planet carrier 26 to the main shaft 16. The main shaft 16 is associated with a set of teeth 74 projecting radially outward, the planet carrier 24 is associated with a set of teeth projecting radially inward 76, the coupling member comprises a radially inward projecting set of teeth 78 engaging with the set of teeth 74 associated with the main shaft 16, and the coupling member further comprising a radially outward projecting set of teeth 79 engaging with the set of teeth 76 associated with the planet carrier 16.

    Abstract: The invention relates to the diagnosis of faults and damage in a gearbox in order to predict the operational life of a gearbox. An end of line test is performed to infer information on each gearbox on the production line. A highly detailed model of the gearbox is created to determine the optimal sensor positions for the end-of-line test so that the test can discriminate between different types of manufacturing variation. This information is then used to construct a unique, highly detailed model for each gearbox. During operation, forces and moments acting on the gearbox are measured at regular intervals and the model is used to continuously update a prediction of the total damage on each gearbox component. The probability of failure in a given time period is then calculated. An existing condition monitoring system approach such as vibration analysis may be used in parallel with the model-based diagnosis. The overall probability of failure for a required lifetime is calculated and, if necessary, operation is limited to provide a required probability of failure in a given time period.
