Embodiment Construction

[0030] figure 1 An assembly 1 according to the invention for supporting a drive train 50 of a wind power plant is schematically shown in . In the drive train 50 of a wind power plant, the figure 1 Only the rotor shaft 51 is shown and the gear transmission 52 connected thereto is partially shown. The gear transmission 52 is a planetary gear, the planetary gear carrier 53 of which is fixedly connected to the rotor shaft. The actual rotor is not shown, comprising rotor blades at the opposite end of the rotor shaft 51 to the gear transmission 52 and a generator arranged at the not shown end of the gear transmission 52 .

[0031] The drive train 50 is supported by an assembly 1 according to the invention consisting of a machine frame 10 and two ring elements 20, 20' fixed there.

[0032] Machine support 10 (it is in figure 2 is shown in isolation and in detail) has two support points 11, 11' spaced apart from each other, at which ring elements 20, 20' are fixed respectively. ...

Abstract

A mainframe (10) mounts the drivetrain (50) of a wind turbine, and to an arrangement (1) comprising such a mainframe (10), and to a wind turbine having a corresponding arrangement (1). For the purposeof mounting the drivetrain (50) of a wind turbine, the mainframe (10) is realized with two bearing points (11, 11') that are spaced apart from each other, a partial flange (12), having a fastening region (13) shaped as a circular ring segment, being provided at at least one bearing point (11, 11'). The arrangement (1) comprises, besides the mainframe (10), at least one ring element (20, 20') configured to radially encompass the drivetrain (50). At least one ring element (20, 20') is fastened to the fastening region (13), shaped as a circular ring segment, of a bearing point (11, 11') of the mainframe (10). In the case of the wind turbine, the drivetrain (50) is mounted by means of the described arrangement (1).

Description

technical field [0001] The invention relates to a machine frame for supporting a drive train of a wind power plant, as well as to an assembly comprising such a machine frame, and to a wind power plant with corresponding assemblies. Background technique [0002] In known wind power plants, a rotor rotatable about a substantially horizontal axis is rotated by the wind. In a typical embodiment, the rotor is fixedly connected here to the rotor shaft and thus to the generator, if appropriate via an intermediate gear transmission, in order to convert the rotational energy of the rotor into electrical energy. The rotating part from the rotor to the generator is called the drive train. [0003] For mounting, it is known as one of several variants to mount the drive train of a wind power plant with a so-called three-point mounting (see eg DE 10 2006 027 543 A1). In this case, the rotor shaft is supported by a front bearing arranged close to the connection area to the rotor and is c...
