Definitions
- the invention relates to a wind energy plant with a tower, a rotatably mounted on the tower about its axis, a gear, a generator, a Schleif ⁇ ring assembly and a brake receiving machine housing and a rotor mounted in the machine housing with at least one rotor blade.
- Wind energy technology has developed very dynamically over the last few decades, although this only applies to medium to very large systems for grid parabolic operation.
- the development of small kilowatt-scale systems has not progressed in the last twenty years.
- these systems continue to be very expensive and therefore do not find market access.
- the use of wind energy to supply the 2 billion people without access to electricity could play an important role here.
- there is a great need for systems in the power class 1 kW to 10 kW but this can only be developed if the systems are extremely robust and cost-effective and easy to set up and work largely maintenance-free.
- the invention is therefore an object of the invention to provide a wind turbine of the type mentioned, in which all components are optimally matched to each other and all components are compactly assembled, so that a lighter and above all cheaper machine set can be realized.
- this object is achieved by the realization of a fully integrated machine set, wherein all components are compactly combined into a cast component.
- These components are the vertical bearing, the slip ring gear, the gearbox, the generator, the brake and the rotor bearing. All components are geometrically arranged so that a very small and lightweight machine housing results. It is particularly advantageous if the machine housing is produced as a cast component in aluminum.
- Fig.l the complete wind turbine with tower, nacelle and rotor, in by
- Fig. 2 is a perspective view of the machine housing
- Fig. 3 is a sectional view of the machine housing with all components.
- Fig. 1 shows the wind turbine with tower 10 and the Turmabhard 12.
- the nacelle 14 On the tower 10, the nacelle 14 is arranged rotatably about its axis.
- the rotor 16 is mounted, the lee finger, ie on the side facing away from the wind of the Tur ⁇ 10 rotates.
- FIG. 2 shows the machine housing 18 in a perspective view, the rotor shaft 20 being visible on the front side and the cooling ribs 22 on the sides of the machine housing 18.
- Fig. 3 shows the machine housing 18 as a sectional drawing.
- the machine housing accommodates a gear 24, a generator 26, a vertical bearing 28, a slip ring transmitter 30 and a brake 32.
- the machine housing 18 is as a
- Cast component formed and has a plurality of bearing seats for receiving the er ⁇ required storage.
- the machine set In order to enable the tracking of the nacelle 14 in wind direction changes, the machine set must be rotatably mounted about the tower longitudinal axis 34. This ge happens via a lower bearing 36 and an upper bearing 38, which are placed on the bolted to the tower 10 journals 40. To transfer the electrical energy from the generator 26 to a cable which is fixedly mounted on the tower 10, a slip ring transformer 30 is needed. This slip ring transmitter 30 is disposed between the bearings 36 and 38 on the journal 40.
- the rotor shaft 20 is rotatably supported by a front bearing 42 and a rear bearing 44 in Ma ⁇ housing 18.
- the rotor shaft 20 carries the rotor 16 (not shown in FIG. 3) and the gear toothed wheel 46.
- the gear 24 is designed as a single-stage helical gear, the gear tooth 46 meshing with the gear tooth 48.
- the gear 48 is fixedly connected to the generator shaft 50 and thus drives the generator 26 at.
- the gearwheel 46 runs in an oil sump 52 formed in the machine housing 18.
- the generator shaft 50 is mounted on a front bearing 54 and a rear bearing 56 gela ⁇ .
- the front bearing 54 is pressed in the machine housing 18 and the rear bearing in the brake 32.
- the front bearing 54 is lubricated with the lubricant of Getrie ⁇ bes 24 and the rear bearing 56 with a separate grease.
- the brake 32 with the rear bearing 56 is screwed to the machine housing 18 and thereby closes the generator room against environmental influences.
- This structure allows an extremely compact and lightweight design of the entire machine set.
- the gear 24 has been brought as close as possible to the vertical bearing 28 and the generator has been arranged above the oil sump 52 and the vertical bearing 28.
- the length of the machine housing 18 is characterized particularly small.
- the machine housing 18 is very inexpensive to produce. It is advantageous if the rotor axis 58 is at right angles to the tower axis 34. The machine housing is particularly easy if an aluminum alloy is used as the material. In addition, the Tru ⁇ unit is limited to a minimum, which also has a positive effect on the cost and reliability of the system.
- a brake 32 is mounted on the free end of the generator shaft 50 Fliehkraft ⁇ brake whose abutment is fixedly connected to the block, or as electrically aus ⁇ dissolved disc brake, the fifth bearing 54 is arranged on the generator shaft an ⁇ order, reduce the otherwise required equipment, especially in cases where the at least one rotor blade is not adjustable.
