Abstract
In the gondola (2) of a wind power plant (1) according to the invention the main shaft comprises several parts. The rotors (21, 45) of the generators (4, 5) are parts of the main shaft. Other shaft sections (17, 18) are used for supporting the main shaft (3) on the machine carrier or, respectively the gondola frame (7) and the attachment of the rotor hub (6). The generators (4, 5) may be completely pre-assembled and delivered as mounting units. During the pre-assembly of the generators, the rotor (21) and the stator (26) are fixed relative to one another by mounting aids. The mounting aids, interlocking devices, are removed after the whole drive train is mounted to the machine carrier (7). The stator of the generator (26) is mounted on the machine carrier (7) via adjustable supports.
Claims3
A gondola (2) of a wind power plant (1) for the generation of electric energy, comprising:
- a gondola frame (7) including first and second main bearings (8, 9) arranged in spaced relationship;
- a hollow main shaft (3) rotatably supported by the first and second main bearings (8, 9) and the hollow main shaft (3) being divided between the first and second main bearings (8, 9) into at least three shaft sections (17, 18, 22);
- the first shaft section (17) is supported by the first main bearing (8), the second shaft section (18) is supported by the second main bearing (9);
- a first generator (4) including a first rotor (21) including the third shaft section (22), the third shaft section (22) operatively arranged between and affixed to the first shaft section (17) and the second shaft section (18), the third shaft section (22) of the first generator (4) and the adjacent first shaft section (17) and second shaft section (18) having the same inside minimum diameter, and the first generator (4) including a first stator (26) connected to the gondola frame (7) so as to be non-rotatable relative thereto;
- a second generator (5) including a second stator (46) and a second rotor (45);
- the first stator (26) of the first generator (4) and/or the second stator (46) of the second generator (5) supported by the gondola frame (7);
- and,
- an adjustable support structure (27, 47) operatively arranged between the gondola frame (7) and the first stator (26) and the second stator (46), the adjustable support structure (27, 47) for supporting the first generator (4) and/or the second generator (5) on the gondola frame (7) so that the first stator (26) is adjustable and concentric with respect to the first rotor (21) and the second stator (46) is adjustable and concentric with respect to the second rotor (45).
