Definitions
- the invention relates to a rotor shaft / hub unit for a wind turbine with a rotor hub connected to a blade or blade bearing connection and provided with a rotor bearing seat.
- the Energyerzeuqunq by a wind turbine basie v L on the energy conversion of translatory movement of air in Rotatio ⁇ senargi, d. ⁇ on the Rotorbl t ⁇ ter occurs.
- the rotor blades together with the rotor hub form the rotor, by means of which the rotational energy in the rotor hub is converted into mechanical energy in the form of a torque.
- This torque is transmitted from the rotor hub to the red shaft and from there via the gearbox to the generator, in which the mechanical energy is converted into electrical energy.
- the hub and shaft are loaded with bending moments, torsional moments, axial and transverse forces, both statically and dynamically.
- the rotor hub and rotor shaft are usually manufactured as individual components from spheroidal graphite cast iron or tempered steel and then screwed together for assembly.
- This design has several disadvantages.
- a disadvantage is that the individual components are very heavy due to the properties of the materials used, which makes component assembly difficult.
- Another disadvantage is the need to screw the individual components together. For this, elaborate connection places with very tight manufacturing tolerances.
- the design of screw connections of two individual components in general and especially under alternating loads makes it necessary to oversize the components locally at the connection point, which in turn has a negative effect on the component costs.
- a rotor is also known in which a pair of rotor blades are held together with a connecting rod. Furthermore, from US BI 6,227,803 a wind turbine with a plastic nacelle box is known, which is attached to a partially elastic tower. The propeller blades of the rotor consist of a c -section and a 1- section section.
- the invention has for its object to provide a rotor in which the rotor is light and easy to assemble.
- this task is solved by the rotor hub and rotor being made in one piece from fiber composite materials.
- the blade or blade bearing connection can be designed as metallic inserts integrated in the laminate of the rotor hub.
- the rotor bearing seat can be designed as a bushing integrated in the laminate of the rotor shaft.
- the invention thus proposes a component combination in which the individual components of the rotor hub and the rotor shaft are combined to form an integral component made of fiber composite materials.
- the combination of the two individual components to form an integral component and the use of fiber composite materials lead to a number of technical and economic advantages.
- fiber composite materials Compared to the commonly used metallic materials, fiber composite materials have a very high specific strength and rigidity, which means that a lighter component can be realized if the same requirements are met.
- Fiber composites are all materials that consist of one or more fiber types and a resin matrix with or without additives.
- a particular advantage of the use of fiber composite materials is that any fibers can be used with any orientation, the direction-dependent mechanical properties of the material thereby precisely to the Bela c ..tungsart and a vote direction. This enables a more extensive weight optimization of the component compared to the use of metallic materials.
- the combination of the two individual components to form an integral component eliminates the need to provide interfaces with narrow manufacturing tolerances that would be required for screwing the Eir17.ej.baute.ile. Local component oversizing to enable screwing is also eliminated. The assembly effort that would be required to screw the two individual components together is also eliminated.
- the weight saving also contributes to further scaling up of the wind energy plants enable, because the tower head mass of the wind turbine is a critical aspect in this regard.
- the invention is explained below with reference to a drawing.
- the single figure shows a schematic cross section through the rotor shaft / hub combination.
- the component body which consists of the main areas rotor hub 3 and rotor shaft 6, is made of fiber composite.
- the blade or blade bearing connection 1 serves to connect the rotor blade directly or via a bearing to the hub 3.
- This connection consists of metallic inserts with blind hole threads which are integrated into the laminate of the rotor hub 3.
- At the front in the rotor hub 3 there is an access hole 2 so that the interior of the rotor hub 3 is accessible.
- a rotor locking disk 4 is used to lock the rotor of the wind turbine during maintenance work and is connected directly to the rotor hub 3 or to the rotor bearing seat 5 by means of an adhesive or screw connection.
- the rotor locking disk 4 consists of + - either from a conventional material or a fiber composite material.
- the rotor bearing seat 5 serves to receive the rotor bearing and is designed in the form of a bush made of metal, plastic or a fiber composite material. This bushing is either integrated into the laminate of the rotor shaft 6 or connected to the laminate of the rotor shaft 6 from the outside by gluing and / or screwing. Spring washer and guide fit 7 are used to connect the rotor shaft 6 to the gearbox.
