Description

The invention relates to a mounting device for a wind turbine, wherein the wind turbine has a tower, a machine housing arranged on the tower and a section provided within the machine housing section unit which is fixed to a machine housing disposed within the machine frame, wherein integrated within the section unit, a transmission and a generator are, wherein the section unit is composed of several individual sections, the individual sections are designed as at least two transmission sections of the transmission and a generator section of the generator, and at least two individual sections are separable from each other.

In the DE 299 24 115 U1 discloses a wind turbine, which consists of a tower, a tower arranged on the machine housing and a gear provided within the machine housing. It has disadvantageously been found that the gears used in the wind turbines are exposed to negative influences, with the result of premature fatigue or even total failure of individual components of the transmission such as wheels and bearings.

However, the replacement of individual, defective components of a wind power transmission is connected by its exposed location with costly difficulties. For this, the system must be shut down for several days and an external mobile crane can be procured, with which the defective components of the gearbox can be lifted from the tower.

The DE 299 24 115 U1 proposes a wind turbine having an on-board crane disposed in the nacelle / engine housing which allows defective components of the transmission to descend from the tower without the aid of an external mobile crane and then pull up operational components of the transmission. Such wind turbines have so far found no significant distribution. On the contrary, older plants that do not have a sufficiently powerful on-board crane need to be repaired.

The object of the present invention is to avoid the above-mentioned disadvantages, in particular to provide a mounting device for a wind turbine, which is suitable for any wind turbines of different construction, while a simple and cost-effective installation of individual gear sections and / or generator sections can be achieved.

In order reliably to move at least one of the individual sections, a linear guide is provided, along which the individual section to be moved can be moved. Before a single section is moved from the other individual section, for example, the individual sections to be traversed can first be suspended from the linear guide. Then the worker can separate the individual sections without a single section falling down to the floor of the machine housing. The worker can now move the respective individual section according to the linear guide and, for example, repair, disassemble or reassemble the respective components within a single section.

A particular advantage of this invention is that the mounting device is designed to be mobile and can be transported by the installer in the machine housing. If the wind turbine has an on-board crane in the machine housing, it goes without saying that the mounting device with its individual components can be hoisted into the machine housing via the on-board crane. In addition, the mounting device can be dismantled into various components, whereby a comfortable transport - for example in a motor vehicle - to the corresponding wind turbine is possible. Another advantageous application of the mounting device according to the invention is in the off-shore area, especially in the sea.

The planet wheel 26 and Sonnerad 30 comb together in a first tooth mesh 31 , When driving the planet carrier 52 leads the planetary gear 26 a planetary movement resulting from the superposition of a first rotational movement about the planetary axis 28 and a second rotational movement about the major axis 50 results.

In addition, the planetary gear meshes 26 via a second tooth engagement 32 with a sun wheel 30 , the integral part of a sun wave 39 is that about a sun camp 40 in the output side section 32 coaxial to the main axis 50 is rotatably mounted. The sun wave 39 and the sun wheel 30 may alternatively be designed as separate, but non-rotatably interconnected components. The planetary motion of the planetary gear 26 gets into a simple rotational motion of sun gear 30 and sun wave 39 around the main axis 50 implemented. In the 7 illustrated section unit 20 may also extend along a longitudinal axis which is oriented to the ground plane at an angle α which is approximately 5 ° in the other embodiments. According to all embodiments, however, the angle should be less than or equal to 10 °. According to the illustrated embodiments, the longitudinal axis runs 50 essentially parallel to the linear guide 10 , wherein adjustment elements, in particular in the region of the node element 14 may be present to a corresponding orientation of the linear guide 10 to the longitudinal axis 50 to enable. The adjustment elements may be, for example, metal sheets that are attached to the node elements 14 can be attached to a corresponding leveling of the linear guide 10 to reach.

In the sectional unit shown in the embodiments 20 can the gearbox 100 a plurality of individual sections 21 . 22 . 23 . 24 exhibit. As a rule, the generator is located 200 spaced from the gearbox 100 as it is in 1 . 3 . 5 and 6 to 7 is shown. In a further alternative, it is conceivable that the section unit 20 designed such that the transmission sections 21 . 22 . 23 . 24 directly with the generator section 25 are connected, which in 2a and 2 B is shown. In this embodiment, the generator section 25 directly on the adjacent gear unit section 23 flanged.
