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.
