Definitions
- the present invention is included within the field of wind turbines, and more specifically, the power train that has a directly coupled generator located inside the gondola and that is connected through its corresponding transmission system to the wind rotor located outside of the gondola.
- the function of the bed of a gondola is in any case to support the power train and transmit the loads not derived from the rotor torque to the tower through the turning ring (Yaw).
- Most manufacturers follow the same fundamental principles in the design of said bench, with ductile iron foundry being the most widespread today.
- US 20050230979 from Northern Power Systems features a directly coupled generator and a rotor, both located on the same side of the tower.
- the brake is integrated into the generator stator and the transformer is under the gondola, inside the tower.
- US 2009 250939 from TianDi Growth Capital describes a power train on a 5 to 10 m platform that is both the gondola's turn system and the bench itself.
- the rotor feeds at least 9 generators.
- the bearings are 10 m apart and there are different sets of gears and gears that move the generators between the axis of rotation.
- Claim 1 characterized in that generators moving the main shaft, rotating below the line rotation system.
- the power train object of the invention comes to solve this and other problems derived from the direct connection between the main shaft and the generator without intermediate gears.
- the type of structure of the power train bed based on frames in front of the complex castings, simplifies both the design and manufacture of the same and allows modularizing to reduce transport, also taking advantage of the large reaction arm of a ring of large diameter rotation. It also allows to efficiently resolve the position of the generator within the turning ring, reduce the height of the main shaft with respect to said ring and therefore reduce the loads thereof.
- the transmission system arranged at the top of the tower determines the structural design of the power train support.
- Another object of the invention is that the support of the main shaft that rests on the support mentioned above and on two other supports that, together with the triangular bench containing them, also support the generator and the brake.
- the generator supports are part of the bench created based on frames with wings and souls, and include their respective bearings one on each side of the group that forms the generator and the brake.
- the generator is integrated in said bed and that in turn partly crosses the connection piece itself arranged on the tower.
- Another object of the invention is to provide the power train object of the invention with a novel turning system (yaw) with a set of rolling elements, sliding on a ring arranged on the annular connection piece supported on the tower .
- traction elements will be available that will activate the gondola's rotation around the tower without the need for the usual pinion-rack gears.
- the motors used by the traction elements will be electric and will activate a series of pneumatic wheels that will roll along the raceway constituted by the turning ring.
- the turning system (yaw) can be passive and does not require a drive system, the traction elements could be eliminated and only the rolling elements that allow the rotation and transmit the loads remain.
- a large diameter turning ring (yaw) is associated with the advantage of a large reduction of the vertical loads resulting in its discrete supports.
- the distance between supports and therefore the flexural loads has also been increased. Therefore, the triangular configuration of the bench takes advantage of the reaction arm and minimizes the loads on the supports, all in the most compact way possible.
- the bench conceived based on frames provides the structure with the necessary flexural stiffness efficiently. To do this, these frames are formed by a wing and a soul with windows or relief. This structure also allows the design to be modularized in order to reduce transport costs and properly accommodate all the elements of the power train: bearings, brake and generator.
- the conceived structure allows the generator to be embedded in the central hollow of the turning ring (Yaw) and of the connecting piece and therefore reducing the distance between the rotor shaft and the turning plane (Yaw), with the consequent reduction of charges that entails.
- Figure 1 is a general view of the wind turbine of the invention.
- Figure 2 is a detail of part of the rotor, the power train and the connection piece with the lattice tower.
- Figure 3 is the same view of Figure 2 but in profile with some sectioned parts
- Figure 4 is a perspective of the bench or fixed support with the hollow shaft
- Figure 5 is an enlargement of the joint of the bed and the connecting piece through the turning system (yaw). A detail of the turning system is added.
- Figure 6 is a second practical embodiment with a different raceway.
- Figure 7 and its variants a, b and c are different embodiments of the drive system according to the embodiments of a raceway ring or another. Detailed description of the invention
- the wind turbine shown is horizontal, with three blades (1) facing leeward and with a lattice tower (2) that keeps its three legs equidistant along its entire length.
- the connection piece (4) is arranged and on it the power train (not shown in the figure) object of the invention.
- the lattice tower (2) supports the connecting piece (4) and on it the bed (5) is arranged triangularly and which houses the generator (6) inside ) and to the main shaft (7) and at one of its ends it supports the rotor (8).
- the connecting piece (4) In the upper part of the connecting piece (4) there is a ring or raceway (9) that is part of the turning system (yaw).
- Said rotation system is made up of said ring (9) and the three supports (10) arranged one at each vertex of the triangle that forms the bench (5).
- the main shaft (7) crosses one of the corners of the bed (5) in the place where a hollow shaft (11) is anchored, which has a main bearing that facilitates the rotation of the rotor (8).
- the triangular bench (5) is formed based on external frames and internal frames.
- the outer frames are formed by the side frames (12) and the bottom frame (13).
- the internal frames in turn are made up of the support frame (14) and the reinforcement frame (15), both delimiting the gap where the generator will be housed. All frames have relief windows (16) evenly distributed throughout their surface.
- the supports (17) of the generator (6) are part of the frames of the bed (5) and include their respective bearings (18) one on each side of the group that forms the generator and the brake (not shown in the figure).
- the bed (5) rests on the connecting piece (4) through the rolling system consisting of a rolling ring (9) and its corresponding supports (10).
- the raceway ring (9) has an inverted T-shape at the base and a circular shape at the top.
- three rolling elements (19) acting on the rolling ring (9) are shown, said rolling elements acting at 120 ° from each other and supporting the horizontal and vertical loads in both directions derived from the rotation of the wind turbine on tower.
- the upper rolling element (19 ') transmits the vertical compression loads towards the tower.
- the two inclined rolling elements (19 ") due to their angle, can withstand both vertical and horizontal tensile loads.
- Figure 6 is another practical embodiment where the raceway ring (9) has a double T shape and the upper part is complemented by two circular shapes and three race elements (19) on each wing of the T, arranged symmetrically in relation to the ring (9) and separated 90 ° each. This arrangement causes the vertical rolling elements (19 ') to transmit only vertical loads and the horizontal elements (19 ") to transmit only horizontal loads.
- Figure 7 are driving systems of the rolling elements according to whether a rolling ring (9) or another is selected.
- the turning system does not support loads but causes the rotation pulled by the traction elements, preferably electric motors (20), which are located above the wheels (21).
- Said pneumatic wheels pull in the central part (22) of the rolling ring (9) as shown in embodiments a and b, or the wheels (21) pull in the upper part (23) of the rolling ring (9) as shown in embodiment c.
- the drive systems are part of the rolling system consisting of the supports (10).
