    FIELD OF THE INVENTION
    5 The present invention relates to a wind turbine and, more particularly, to
    a wind turbine with its power train structured in modules to facilitate
    Its installation and maintenance.
    BACKGROUND OF THE INVENTION
    10
    The main structural components of the power train of a
    Typical wind turbines are the rotor hub, the main shaft and the multiplier that
    It is connected to the generator by a high-medium speed shaft. The purpose
    main of these structural components is to transfer the torque
    fifteen generated by the rotor to the generator and increase the shaft speed in order to
    achieve an adequate rotational speed of the generator rotor. An objective
    secondary is to transfer the rotor weight, thrust and moments
    asymmetric rotor, that is, the moments of rotation and orientation to the frame
    main and then to the tower and the foundations.
    2O In the development of the wind industry, the integration of components has
    been an important factor to achieve compact wind turbines minimizing
    as much as possible the weight of the power train and avoiding the mutual interference of the
    external and internal loads on the different components. As examples of
    This trend includes the wind turbine described in EP 1 373 720 B 1 and the
    25 multiplier described in EP 2 072 863 B 1.
    Another notable trend is the standardization of components and how
    an example of it can be cited the multiplier described in US 20101009799
    A1.
    Both the integration and the standardization of components try to
    30 meet the demand of the wind industry of structured wind turbines of
    way to facilitate assembly and maintenance.
    The present invention is also intended to meet that demand for, in particular, both terrestrial and marine wind turbines of a power greater than 3 MW.
    5 SUMMARY OF THE INVENTION
    10 15 20 2 5 The present invention provides a wind turbine with a structured power train to facilitate its assembly and maintenance, allowing in particular the replacement of damaged components. In particular, the section of the power train corresponding to the main axis and the first stage of the multiplier is structured in two separable modules, the first module comprising the main axis, its housing and two bearings and the second module comprising the first stage of the multiplier , its housing and a double tapered bearing on the side adjacent to the first module as a support medium for the first stage of the multiplier in its housing. In addition, said section of the power train comprises a connection device between the main shaft and the satellite carrier of the first stage of the multiplier configured so as to allow a flexible coupling between them. In one embodiment, the satellite carrier comprises a "bogie" plate that supports a plurality of planetary axes in which planetary gears are rotatably mounted by means of bearings on both sides of the "bogie" plate. Other features and advantages of the present invention will be readily apparent from the following detailed description of the invention and from the claims in relation to the accompanying figures.

    Detailed description of the invention
    The wind turbine 11 referred to in this invention comprises (see Figure
    1) a tower 14 supporting a gondola 15 housing a generator 27 for the
    10 wind turbine rotor rotational energy conversion into energy
    electric The rotor of the wind turbine consists of a hub 12 and, generally, three
    blades 13. Bushing 12 is connected through a main shaft 21 to a
    multiplier 23 which, in turn, is connected to generator 27 through an axis
    high-medium speed 24 to transfer the torque generated by the rotor of the
    fifteen wind turbine and thereby achieve an adequate rotor rotation speed
    of the generator.
    The present invention relates in particular to the structuring of the
    first part of the power train (see Figure 2) in a first module 31 and a
    second module 41.
    2 o The first module 31 comprises the main shaft 21, the shaft housing 33
    main 21 and two bearings 35, 37 as main shaft support means 21
    in its accommodation 33 which, in turn, has means of union (not
    shown in Figure 2) to the gondola 15 resistant structure for
    transfer the loads transmitted by the main shaft 21 so that, in turn, the
    25 transfer to tower 14 and its foundation.
    The second module 41 comprises the first stage 42 of the multiplier
    23, the housing 43 of the first stage 42 of the multiplier 23 and a double
    tapered bearing 45 arranged in an "X" or "O" configuration as a medium
    of support of the first stage 42 of the multiplier 23 in its housing 43
    30 which, meanwhile, has joining means (not shown in Figure 2) to
    the sturdy structure of the gondola 15 to transfer the transmitted loads
    by the first stage 42 of the multiplier 23 so that, in turn, it transfers them to
    tower 14 and its foundation
    The first stage 42 of the multiplier 23 is of the planetary type and in the
    Figure 2 shows only the satellite carrier 47 and the crown 49. The fact that
    5 the support means of the first stage 42 of the multiplier 23 are
    located on the side of it adjacent to the main shaft 21 allows reducing its
    axial dimension with the consequent reduction of weight.
    The union / separation between the first module 31 and the second module 41 is
    carried out by joining / separating their respective housings 33, 43 AND
    10 on the other hand joining / separating the main shaft 21 and the satellite carrier 47 of the
    multiplier 23.
    The first is carried out using joining / separating means
    conventional (not shown in Figure 2) between these types of structures.
    The second is carried out by means of a shaft connection device 51
    fifteen main 21 and satellite carrier 47 configured to provide a coupling
    flexible between both that allows transmitting the torque generated by the rotor of the
    wind turbine 11 and filter and not let those other efforts of the rotor (weight,
    thrust and asymmetrical rotor moments) as they are absorbed by the
    bearings 35, 37 of main shaft 21. This way you get the
    2 o only forces introduced into the first stage 42 of the multiplier 23
    be those generated by the connection device 51 itself being
    normally much lower than those generated by the rotor.
    That connection device 51 may be configured, for example, by
    two cooperating parts connected to the main shaft 21 and the satellite carrier 47 and about
    25 complementary elastomeric means arranged to absorb
    possible radial misalignments between them.
    Other configurations of a connection device 51 allowing said
    Flexible coupling are described in patent application WO 2012/052022 A 1.
    The combination of a flexible coupling between the main shaft 21 and the
    30 satellite carrier 47 of the first stage 42 of the multiplier 23 with double
    taper bearing 45 clamping the first stage 42 of the multiplier 23
    arranged on the side adjacent to the first module 31 allows the only
    forces from the rotor that are transmitted to the first stage 42 of the multiplier 23 are those of the torque which facilitates the structuring of the first part of the power train in the modules 31, 41.
    In a preferred embodiment, the first stage 42 of the multiplier 23 5
    is configured (see Figure 3) with a satellite carrier 47 comprising a "bogie" plate 65 that supports a plurality of planetary shafts 71 in which planetary gears 55, 55 'are rotatably mounted by means of bearings 67, 67' a both sides of the bogie plate 65. The motor torque transmitted by the main shaft 21 to the satellite carrier 47 is in turn transmitted to the planetary gears 55, 55 '. The
    10 interaction of the planetary gears 55, 55 'with the static crown 49 and with the solar gear 57 transmits the torque to the axis 63. This configuration of the first stage 42 of the multiplier 23, known as the "bogie" configuration, contributes to prevent mismatches of planetary axes 71 with respect to crown 49. In other words, solar gear
    15 57, the planetary gears 55, 55 'and the crown 49 are substantially aligned in a direction parallel to the axial axis of rotation of the satellite carrier 47. Thus, if the combination of a flexible coupling between the main axis 21 and the multiplier 23 with the double tapered bearing 45 for securing the first stage 42 of the multiplier 23 a configuration is added
    20 "bogie" of the first stage 42 of the multiplier 23 has a greater guarantee that the only forces from the rotor transmitted to the multiplier 23 are those of the torque.
    Although the present invention has been described in relation to various embodiments, it will be appreciated from the description that various combinations of elements, variations or improvements can be made and are within
    of the scope of the invention.
