Method of vertically assembling a generator of a wind turbine
View Patent ↗A method of vertically assembling a generator of a wind turbine is provided. The method includes A rotor part is arranged on a horizontal assembly which supports components of the generator such that a rotational axis of a component is essentially vertical during assembly, and the assembly support is configured to allow access to an interior of a generator component during the assembly procedure; a stator part is arranged in the rotor part; and the stator part is joined to the rotor part. An assembly arrangement for a vertical assembly of a generator of a wind turbine is provided. The assembly arrangement includes a horizontal assembly support for supporting components of the generator such that a rotational axis of a component is essentially vertical during assembly, and the assembly support is configured to allow access to an interior of a generator component during the assembly procedure.
1. A method of vertically assembling a generator of a wind turbine using an assembly arrangement including a horizontal assembly support, the method comprising:
arranging a rotor part onto the horizontal assembly support which supports components of the generator such that a rotational axis of a component of the generator when operating to generate electricity is essentially vertical during assembly of a stator part to the rotor part, and the horizontal assembly support is configured to allow a human body to extend into an interior of a component of the generator during assembly of the stator part to the rotor part;
assembling the stator part to the rotor part including:
arranging the stator part in the rotor part; and
joining the stator part to the rotor part to form at least a portion of the generator for the wind turbine; and
mounting a stabilizing ring to the rotor part prior to loading a plurality of magnets into the rotor part, wherein the plurality of magnets are mounted to the rotor part after the arranging the stator part in the rotor part.
2. The method according to claim 1 , further comprising:
mounting the rotor part to a bearing.
3. The method according to claim 1 , further comprising:
mounting an anti-ovalization ring to the bearing.
4. The method according to claim 1 , wherein the arranging the stator part in the rotor part comprises lowering the stator part into the rotor part.
5. The method according to claim 4 , further comprising:
fastening the rotor part to the horizontal assembly support prior to the arranging the stator part in the rotor part.
6. The method according to claim 1 , wherein the assembly arrangement comprises an assembly table and a plurality of essentially vertical supporting columns, and wherein the horizontal assembly support comprises an essentially horizontal upper surface of the assembly table.
7. The method according to claim 6 , wherein the assembly table comprises an access opening shaped according to an opening of the rotor part.
8. The method according to claim 1 , wherein the assembly arrangement comprises a plurality of spacer blocks mounted to the assembly support in order to provide access to the underside of the rotor part.
