Abstract: Aspects of the present invention relate to a rotor arrangement (42) for a wind turbine generator (24). The rotor arrangement (42) comprises a cylindrical ring structure (46) arranged to rotate around a rotational axis. The cylindrical ring structure (46) comprises: a plurality of ring-shaped permanent magnet packages (48) arranged coaxially around the rotational axis, a plurality of tie rods (55) extending axially through the plurality of permanent magnet packages (48) to join the plurality of permanent magnet packages (48) together; and one or more spacer components (64; 164) located between at least one axially adjacent pair of the plurality of permanent magnet packages (48) to space the respective pair of permanent magnet packages (48) apart, wherein the one or more spacer components (64; 164) are configured to act as an impeller as the rotor rotates, in use, thereby to cause air to flow in a radial direction, with respect to the rotational axis of the rotor arrangement (42), between the at least one axially adjacent pair of permanent magnet packages (48). The generator rotor arrangement uses a portion of the kinetic energy of the rotating rotor arrangement to generate a radial air flow that flows between and/or around the magnet packages to transfer heat away from the magnet packages, and thereby to provide a cooling function.

Abstract: Apparatus comprising a first shaft and a second shaft supported in a substantially concentric relationship so that they are able to rotate relative to one another about a rotational axis (R); wherein one of the first and second shafts passes through a bore defined in the other of the first and second shafts; a seal arrangement between the first and second shafts, said seal arrangement being locked from rotational movement relative to said first shaft; wherein the seal arrangement comprises a first portion that is rotatably mounted on the second shaft by a bearing and a second portion that is configured to seal against a miming surface defined by the second shaft. Advantageously, since the seal arrangement is rotatably mounted on the same shaft against which it forms a seal, the sealing arrangement accommodates for alignment errors between the first and second shafts.

Abstract: A generator-gearbox assembly for a wind turbine A generator-gearbox assembly (200) for a wind turbine (100) comprising a generator (240) having a generator rotor (245); a gearbox (220) comprising an output shaft (230); and a connection assembly (300). The connection assembly (300) comprises a hub abutment surface (310), provided at an end (235) of the output shaft (230) and a plurality of shaft bolt holes (315); a hub (320) associated with the generator rotor (245) and comprising a body (325) and a first connecting portion (340) having a shaft abutment surface (345) facing towards the hub abutment surface (310) and at least one elongated slot (360) extending through the first connecting portion (340). The number of elongated slots (360) is less than or equal to the number of shaft bolt holes (315). A plurality of fasteners fixedly connect the hub (320) to the hub abutment surface (310), each fastener extending through a respective elongated slot (360) and a shaft bolt hole (315). Beneficially, the arrangement of the hub component with elongated slots to accommodate fixing fasteners reduces the likelihood of having to manoeuvre a cumbersome drive shaft or generator rotor into an exact position for attachment to each other. Since the slots are elongated, when the drive shaft is arranged to abut the first flange during assembly it is more likely that the shaft bolt holes of the hub abutment surface align with the elongated slots of the first flange, and so it is more likely that a connection can be made between the drive shaft and the rotor.

Abstract: An electrical power generator for a wind turbine comprising: a generator housing, a stator at a radially outward position and a rotor in a radially inward position, wherein the rotor comprises a cylindrical ring structure arranged about a rotational axis, R, and defining a central hollow portion. The electrical power generator further comprises a rotor shroud attached to the generator housing and which extends about the rotational axis, R, wherein the rotor shroud includes a dome portion that extends into the central hollow portion of the rotor so as to protect the cylindrical ring structure of the rotor. Advantageously, the rotor shroud provides a tunnel-like surface that extends into the central hollow portion of the generator so as to prevent objects such as tools from contacting components of the rotor. The invention also relates to a method for 15 assembling such an electrical power generator with a rotor shroud.
