Definitions
- the present invention relates to a wind turbine with a gear whose input is coupled to a rotor shaft, wherein a separate bearing is provided for the rotor shaft.
- the last-mentioned bearing types are also referred to as three-point bearing, wherein the front bearing of the rotor shaft forms the main or rotor bearing and the rear bearing is taken over by the transmission, which in turn is supported laterally (left and right) on a machine frame.
- the rotor Connected to the rotor shaft and thereby to the drive train and carried by this is the rotor, consisting of the rotor hub and the rotor blades.
- the rotor When working on the drive train, to which the gearbox must be dismantled, the rotor must be dismantled in known wind turbines together with the drive train and the rotor. This is associated with considerable effort.
- EP 1 291 521 A1 proposes to screw the rotor hub to the machine carrier or the front wall of the machine house, so that the rotor on the Wind turbine can remain while the gearbox is repaired and lifted out of the machine house.
- the invention has for its object to provide a simple way to a possibility to export work on a gear in a wind turbine can, without having to disassemble the driveline largely.
- the wind turbine according to the invention has a gear whose input shaft is coupled to a rotor shaft.
- the rotor shaft is held by a separate rotor bearing, with the rear bearing integrated into the gearbox.
- a holding device is provided which holds the rotor shaft in a predetermined position, when a support of the rotor shaft through the transmission is missing.
- the holding device according to the invention in this case takes over the support of the rotor shaft, so that the transmission can be decoupled from the rotor shaft.
- the holding device preferably has a holding frame which is provided for detachable connection to a machine carrier. In its mounted position, the holding frame spans the rotor shaft.
- the holding device preferably has two jaws which engage around the rotor shaft in an assembled position.
- the holding device is further provided with clamping elements, which can be stretched between a jaw and the holding frame, respectively, in order to hold the jaws on the holding frame.
- two clamping elements are provided for each jaw.
- the jaws of the holding device are placed in a preferred embodiment around the rotor shaft, connected to each other and over the Clamping elements connected to the support frame. Subsequently, the holding frame is mounted on the machine frame in a position spanning the rotor shaft.
- the machine support also supports the transmission, as well as the separate bearing of the rotor shaft.
- a pressure ring is provided which - connected to the holding device - exerts a force in the axial direction in order to decouple the rotor shaft from the input of the transmission.
- FIG. 2 shows the support frame of Figure 1 in the view from the front with inserted jaws
- FIG. 5 is an enlarged view of Figure 4 with to be attached holding jaws
- FIG. 6 shows a view from FIG. 5 with attached holding jaws
- Fig. 10 machine frame with attached Rranfuß in the perspective view obliquely from above and
- Fig. 11 machine carrier with crane foot mounted in the view from the side.
- FIG. 1 shows a carrier frame 10 which has mounting plates 12 at its ends. From the mounting plates each extend a plurality of profile sections.
- a first profile section 14 is formed as a double-T-profile and has a bore 16. Subsequent to the first profile section 14 is followed by a second profile section 18, which is inclined relative to the first profile section.
- the second profile section 18 has on its outwardly facing side a stop lug 20 with a central bore 22.
- a central carrier profile 24 which is connected on both sides with second carrier profiles 18.
- the central carrier profile 24 has two edge portions 26, which are separated by a central central region 28.
- the lateral areas 26 are provided with holes 30.
- the center support 24 is reinforced for stabilization, in particular in its central region 28, in which additionally the double T-profile is laterally provided with a wall (compare Fig. 9).
- FIG. 2 shows the support frame 10 with four attached clamping elements 32 which are held in the bores 16 and 30.
- the clamping elements 32 in turn can be adjusted via a central element 34 in its length.
- the clamping elements 32 are each connected in pairs to one of the jaw elements 36, 38.
- the jaw members 36, 38 comprise the rotor shaft.
- Figure 3 can be seen in the top view that in front of the support frame 10, a pressure ring 40, 42 can be set, which is connected via lifting elements 44 with the holding jaws 36 and 38.
- FIGS. 4 to 9 subsequently illustrate the procedure of installation and illustrate the mode of operation of the holding device.
- FIG. 4 shows, in a perspective view from the front, a machine carrier 46, as used in a three-point bearing in a wind energy plant.
- the main bearing is supported on the machine carrier 46 in the region 48 and supports the rotor shaft 50 in the region 52.
- the gear 54 with the integrated bearing is supported in 56 and 58.
- FIG. 5 shows how the holding jaws 36 and 38 are lowered and, as indicated by the arrows A, the rotor shaft 50 is included.
- the retaining jaws consist of disks arranged parallel to one another, which support a retaining surface 60 adapted to the geometry of the rotor shaft 50.
- each holding jaw 36 or 38 has at their end faces bearing surfaces 62 which are provided with holes 64.
- FIG. 6 shows the attached holding jaws 36 and 38 in the non-connected state.
- Figure 7 shows the holding jaws 36 and 38 with attached clamping elements 32.
- the holding jaws 36 and 38 can be set with pre-assembled clamping elements 32 to the rotor shaft 50.
- the support frame 10 is deposited on the machine frame 46.
- the support frame 10 is bolted to the machine frame 46 and the clamping elements 32 are inserted and tightened to hold the rotor shaft.
- the support frame may also consist of several parts, which are lifted separately from each other in the nacelle of the wind turbine and then assembled together.
- Fig. 9 the mounted holding device is shown partially cut to allow the view of the gear 54 with the cone clamping element 53 and the pressure ring 40, 42 with the elements 44.
- the pressure ring 40, 42 is attached and connected via lifting elements 44 with the holding device.
- the lifting elements are advantageously designed as a hydraulic cylinder, other embodiments are conceivable.
- the associated with the holding jaws 36, 38 lifting elements 44 push the gear 54 including cone clamping element 53 of the rotor shaft 50.
- FIG. 10 and 11 additionally show a crane foot 66 which is mounted on the machine frame 46.
- the Rranfuß 66 has four legs 68, which are each connected to the machine frame 46 for themselves.
- the crane foot 66 has between each pair of legs 68 a recess which allows the crane foot 66 to be set up with the holding frame 10 mounted. This makes it possible, with a separately placed on the machine frame 46 crane to lift loads in lower mounted carrier frame 10 and lower.
