Problems solved by technology

The disadvantage of this technical solution is that the thickness and structure of the laminated shell in which the bolted connections are embedded must be able to be adjusted for the thickness (i.e. diameter) of the bolts

Embodiment Construction

[0082] The illustrations in the figures are in schematic form. It should be noted that in different drawings, similar or identical elements may have the same reference numerals.

[0083] exist figure 1 In , a wind turbine 10 is shown. Wind turbine 10 includes a nacelle 12 and a tower 11 . A nacelle 12 is mounted at the top of the tower 11 . The nacelle 12 is mounted rotatable relative to the tower 11 by means of a yaw bearing. The axis of rotation of the nacelle 12 relative to the tower 11 is called the yaw axis.

[0084] Wind turbine 10 further includes a hub 13 with one or more rotor blades 20 . The hub 13 is mounted rotatably relative to the nacelle 12 by means of main bearings. The hub 13 is mounted rotatably about a rotor axis of rotation 14 .

[0085]Wind turbine 10 further includes a main shaft connecting hub 13 to a rotor of generator 15 . If the hub 13 is directly connected to the rotor, the wind turbine is called a gearless direct drive wind turbine. Alterna...

Abstract

The invention relates to a rotor blade (20) of a wind turbine (10) with a first rotor blade segment (30) and a second rotor blade segment (40). The rotor blade (20) comprises a hollow space (51) surrounded by a shell (52). The first rotor blade segment (30) is connected with the second rotor blade segment (40) by a bolt connection. The bolt connection comprises a first connection means of the first rotor blade segment (30), a second connection means of the second rotor blade segment (40), and a bolt (61) establishing a bolted joint between the first connection means and the second connection means. At least the bolt (61) is situated in the hollow space (51) of the rotor blade (20). Furthermore, the invention relates to a method of connecting a first rotor blade segment (30) of a rotor blade (20) of a wind turbine (10) and a second rotor blade segment (40) of the rotor blade (20).

Description

technical field [0001] The invention relates to a rotor blade of a wind turbine having a first rotor blade segment and a second rotor blade segment. The two rotor blade segments are connected by a bolted connection. Furthermore, the invention relates to a method of connecting a first rotor blade segment of a rotor blade and a second rotor blade segment of a rotor blade of a wind turbine, wherein the method comprises the step of establishing a bolted connection between the two rotor blade segments. Background technique [0002] In recent years, wind turbines have become larger, resulting in larger rotor diameters. Consequently, the rotor blades of wind turbines are also becoming larger and larger. Today, the rotor blades of wind turbines can easily exceed 50 meters. This leads to challenges for the structural design of the rotor blade. Furthermore, this leads to challenges in transporting the rotor blades from the manufacturing location to the installation location of the...
