Abstract: A wind turbine including a drive train. The drive train includes at least a rotor for transforming wind into rotation of a rotor hub, to provide a drive torque, a generator for transforming at least a part of the drive torque into electrical power, and at least one coupling for connecting a first drive train component to a second drive train component for transferring the drive torque between the components. The coupling includes a first coupling part with a first coupling area, the first coupling area being connected with a second coupling area of a second coupling part, whereby the drive torque is transferred from one of the areas to the other of the areas during operation of the coupling.

Abstract: A gear system (1) comprising a main bearing (3), a main gear (5) and two or more pinion shafts (6). The main bearing (3) directly supports a torque inputting means (2) and defines a rotational axis (4). The pinion shafts (6) are each arranged to mesh with the main gear (5) at an exterior surface (7) of the main gear (5) in such a manner that torque transmitted from the main gear (5) is split into a number of parallel torque paths corresponding to the number of pinion shafts (6). At least the main gear (5), and at least part of its meshes to the pinion shafts (6) are arranged within a perimeter defined by the main bearing (3). The gear system (1) is compact due to the arrangement of the main gear (5) and meshes to the pinion shafts (6). At the same time it is easy and cost effective to manufacture because the pinion shafts (6) mesh to the main gear (5) via the external surface (7).

Abstract: A gearbox for a wind turbine. The gearbox includes at least one first epicyclical gear stage, at least one second gear stage, and a torque transferring shaft including a shaft part and a connection part, wherein the torque transferring shaft is adapted for connecting a first gear of the first epicyclical gear stage with a second gear of the second gear stage and wherein the torque transferring shaft is connected to the second gear stage via the connection part to form a torque-transferring connection area between the connection part and the second gear stage and wherein the outer diameter of the shaft part of the torque transferring shaft is smaller than an inner diameter of the connection area between said torque transferring shaft and said second gear stage.
