Wind turbine power transmission system and method of installing a wind farm including same

摘要

A power transmission system for a wind turbine comprises a gearbox and generator. The gearbox includes a gear-box housing and gearbox output member. The generator includes: a generator housing having a drive-end side and non-drive-end side, the drive-end side being coupled to the gearbox housing; a stator supported by the generator housing; a rotor coupled to the gearbox output member so as to be driven thereby; a non-drive-end shield coupled to the non-drive-end side of the generator housing; and at least one auxiliary drive mounted to the non-drive-end shield. The at least one auxiliary drive is configured to rotate the turning gear. A corresponding method of installing a wind farm including such a power transmission system is also provided.

1. A power transmission system for a wind turbine, comprising:
a gearbox having a gearbox housing and a gearbox output member extending from the gearbox housing; and a generator integrated with the gearbox, the generator including:
a generator housing coupled to the gearbox housing;a stator positioned within the generator housing;a rotor coupled to the gearbox output member so as to be driven thereby, the rotor being positioned within the generator housing and effectively dividing the generator housing into a drive-end side and non-drive-end side, the drive-end side being coupled to the gearbox housing, the stator being supported between the drive-end side and non-drive-end side;a non-drive-end shield coupled to the non-drive-end side of the generator housing and having a recess radially disposed about the rotor;an end adaptor coupled to the rotor and extending out of the generator housing so as to nest within the recess;at least one auxiliary drive mounted to the non-drive-end shield; anda turning gear positioned outside the generator housing next to the at least one auxiliary drive, the turning gear being coupled to the end adaptor so that at least a portion of the turning gear is received in the recess, the at least one auxiliary drive being configured to rotate a respective pinion that meshes with the turning gear.
