A gear unit 130 for use in a wind turbine drive arrangement, the gear unit 130 having an integrated rotor bearing arrangement and interfaces with the nacelle 160 and rotor hub of the wind turbine. The geometry of the gear unit 130 and its interface with the nacelle 160 and rotor hub are arranged to allow disassembly of the gear unit 130 in an axial direction away from the rotor hub. The interface between the nacelle and hub may include a releasable static connection 15. The gear unit may consist of a number of modules 6,8,9,10,11,12, each having a weight less than half the overall gear unit weight, and may be disassembled via an on-board crane in the nacelle. Disassembly of the gear modules may be in an axial direction away from the rotor hub. The gear unit may be an epicyclical, sun and planet system. The high speed shaft 13 of the epicyclic gear unit may be connected to a generator 140 via a flange connection. |
