Abstract
The invention relates to a process for producing a rotor blade for a wind power system, wherein at least two rotor blade elements are arranged one behind the other in a longitudinal direction of the rotor blade and are glued together via at least one, preferably at least two connecting elements bridging a partition line between the rotor blade elements, wherein at least one connecting element is aligned with said rotor blade elements, wherein a hollow space is formed between an outer delimitation surface of at least one of the rotor blade elements and at least one fixing segment of the inner delimitation surface of said connecting element, and subsequently the hollow space is flooded with an adhesive (resin).
Claims31
A process for producing a rotor blade for a wind power system, wherein at least two rotor blade elements are arranged one behind the other in a longitudinal direction of the rotor blade and are glued together via at least one connecting elements bridging a partition line between the rotor blade elements, wherein at least one connecting element is aligned with said rotor blade elements, wherein a hollow space is formed between an outer delimitation surface of at least one of the rotor blade elements and at least one fixing segment of the inner delimitation surface of said connecting element, and subsequently the hollow space is flooded with an adhesive.
A rotor blade for a rotor of a wind power system having at least two rotor blade elements arranged one behind the other in a longitudinal direction of the rotor blade and being glued together, comprising at least one connecting elements bridging a partition line between the rotor blade elements and having at least two adherend segments, wherein each of them is glued together with one of the rotor blade elements over a large surface.
A wind power system, comprising a rotor having at least one rotor blade and being pivoted about a rotor axis extending approximately horizontally, wherein the rotor blade comprises at least two rotor blade elements arranged one behind the other in a longitudinal direction of the rotor blade and being glued together, comprising at least one connecting elements bridging a partition line between the rotor blade elements and having at least two adherend segments, wherein each of them is glued together with one of the rotor blade elements over a large surface.
A rotor blade element for the rotor of a wind power system, wherein the rotor blade element is connectable with at least one further rotor blade element to form a rotor blade, wherein the rotor blade element and the at least one further rotor blade element are arranged one behind the other in a longitudinal direction of the rotor blade, and the rotor blade element has a recess at the end connectable with the further rotor blade element which is part of a space filled with adhesive in the connected state.
A connecting element for bridging a separation line between rotor blade elements for a rotor blade of a wind power system, comprising:
- at least two fixing segments, wherein the at least two fixing segments taper towards the surface of the connecting element in a wedge-shaped manner beginning from the separation line between the rotor blade elements;
- and
- locking segments surrounding said fixing segments,
- wherein the connecting element has diminutions directed outwardly in the direction of the longitudinal axis of the rotor blade elements to be connected, and
- wherein the diminutions are formed in such a way that the connecting element forms a hollow space with the rotor blade elements to be connected.
