    equipped wind turbine.
    A generic planetary gear is known for example from WO 2011127509 A1.
    known to the same applicant.
    Another generic planetary gear is known from EP 2 383 480 B1. The planetary gear known from EP 2 383 480 B1 has the disadvantage that in the event of a power failure and thus a failure of the auxiliary
    gregates, which provide lubrication of the plain bearings,
    tion of the planetary gear can come.
    The object of the present invention was to overcome the disadvantages of the prior art and to provide a planetary gear for a wind power plant with
    to provide increased reliability.
    This object is achieved by a device and a method according to the claims.
    Chen solved.
    According to the invention, a planetary gear, in particular a planetary gear, is provided for a wind turbine. The planetary gear includes:
    - a planetary gear housing;
    - at least one sun gear;
    - at least one ring gear;
    - A planet carrier with a first planet carrier cheek and a second planet carrier cheek;
    - At least one planet pin, which is included in the planet carrier
    N2018 / 19600-AT-00
    - At least one planet gear which is mounted on the planet gear pin;
    at least one planetary radial sliding bearing, which is used for mounting the planetary gear on the planetary gear pin and has a sliding surface,
    wherein an oil distribution channel section is formed at least in the planet gear pin, which is fluidly connected to at least a portion of the sliding surface, an oil reservoir is formed in the planet gear pin or in the planet carrier, which is fluidly connected to at least a portion of the sliding surface of the planetary radial slide bearing, the oil reservoir being coupled to an oil reservoir filling channel , Which has an oil reservoir filling opening, which opens into an interior of the planetary gear housing, the oil reservoir filling opening being designed such that, when the planet carrier rotates about a center line, it dips into an oil sump formed in the planetary gear housing.
    A check valve is arranged in the oil reservoir filling channel, which is designed such that an oil flow from the oil reservoir filling opening into the oil reservoir is made possible and an oil flow in the opposite direction is prevented.
    is bound.
    The planetary gear according to the invention has the advantage that, by using the check valve, the oil reservoir can be filled with lubricating oil if it is immersed in the oil sump and no lubricating oil can escape from the oil reservoir in the opposite direction. In particular, if the oil reservoir is coupled to a lubricating oil supply, such as a pump, it is necessary that the lubricating oil pumped into the oil reservoir cannot escape into the interior of the planetary gear housing via the oil reservoir filling channel during normal operation. These measures ensure surprisingly good
    and emergency running properties achieved.
    Furthermore, it can be expedient if an oil collecting element is formed in the area of the oil reservoir filling opening, which is protruding from an outer surface of the planet carrier and funnel-shaped in the direction of rotation
    is open. By means of the oil collecting element, an improved

    Furthermore, it can be provided that the check valve comprises a membrane made of a flexible material. Such a membrane in particular can have a simple structure and thus function well as a check valve.
    yaw.
    Alternatively, it can be provided that the check valve includes a poppet valve, in particular a spring-loaded poppet valve. A spring-loaded poppet valve has the advantage that it can withstand high pressures
    can and also has the simplest possible structure.
    In a further alternative it can be provided that the check valve
    a flap, in particular a spring-loaded flap, comprises.
    In yet another alternative it can be provided that the check valve comprises a gravity-operated closing mechanism. A gravity-operated locking mechanism can be designed such that it releases the oil reservoir filling channel when the oil reservoir filling opening is within the lubricating oil sump and that the flow connection is closed when the oil reservoir filling opening emerges from the lubricating oil sump. The gravity-operated locking mechanism can comprise, for example, a float. The float can, for example, close the oil reservoir filling opening as soon as it dips into the lubricating oil sump. Furthermore, it is also conceivable for the gravity-operated closing mechanism to fill the oil reservoir
    Opening closes or releases depending on the angular position of the planet carrier.
    Furthermore, it can be expedient if an oil reservoir is removed for each planet gear pin.
    is formed.
    N2018 / 19600-AT-00
    supply of the planetary gear can be supplied with lubricating oil.
    Furthermore, it can be provided that the oil reservoir is connected to the oil distribution channel section of the planet gear pin in such a way that, in an uppermost position of the planet gear pin in question, the lubricating oil can reach the sliding surface of the planetary radial slide bearing by gravity. This has the advantage that the lubricating oil without pressure build-up inside
    of the oil reservoir can be guided to the sliding surfaces.
    There is also a wind turbine with a rotor; a gondola; a generator arranged in the nacelle; and a planetary gear for transmitting and translating a torque from the rotor to the generator. The
    Planetary gear is designed according to the above statements.
    For a better understanding of the invention, this is based on the following

    24, 25) of the plain bearings (14, 22, 23) can be supplied with lubricating oil.
    It can further be provided that at least one planetary radial sliding bearing 14 is provided for mounting the planetary gears 5 on the planetary gear bolts 6 per planetary gear 5. According to a first embodiment variant, the planetary radial sliding bearing 14 is fastened to an inner lateral surface 15 on the planetary gear pin 6.

    Oil holes 18 of the planetary radial slide bearing 14 open out.
    Furthermore, it is provided that the oil distribution channel sections 13 of the first planet carrier cheek 8 are flow-connected to the oil distribution channel sections 20 of the planet gear pin 6. It can thereby be achieved that the sliding surface 17 of the planetary radial sliding bearing 14 is supplied with lubricating oil
    can.
    In an alternative embodiment variant, not shown, it can be provided that the planetary radial sliding bearings 14 are firmly received in the planetary gear 5 by means of their outer side surface 16 and the sliding surface 17 of the planetary radial sliding bearings 14 is formed on their inner side surface 15, which interact with the planetary gear pin 6. It can be provided here that a lubricating oil collecting pocket for supplying the sliding surface 17 with lubricating oil
    is formed right in the planet gear pin 6.
    In addition, a first axial slide bearing 22 and a second axial slide bearing 23 can each be arranged on the end face of a planet gear 5. In particular, it can be provided that the first axial sliding bearing 22 is arranged between the planet gear 5 and the first planet carrier cheek 8. Analogously, it can be provided that the second axial sliding bearing 23 between the planet gear 5 and the
    second planet carrier cheek 9 is arranged.

    facing and sliding on this.
    As can also be seen from FIG. 1, it can be provided that an oil sump 27 is formed in an interior 26 of the planetary gear housing 11, which is filled with lubricating oil up to a lubricating oil level 35. The lubricating oil level 35 is selected so that the planet carrier 7 is at least partially immersed in the oil sump 27. In particular, the lubricating oil level 35 is selected such that the individual planet gear bolts 6, when the planet carrier 7 rotates about the center line 2 of the planetary gear 1, in their lowest position.
    at least partially immerse in the oil sump 27.
    FIG. 2 shows a first exemplary embodiment of the installation situation of the planet gear pin 6 in the planet carrier 7, the same reference numerals or component designations being used for the same parts as in the previous FIG. 1. In order to avoid unnecessary repetitions, the detailed
    spelled in the previous Fig. 1 referred to.
    As can be seen from FIG. 2, it can be provided that an oil reservoir 28 is formed in the planet gear pin 6, which is used for the temporary storage of lubricating oil
    serves. The oil reservoir 28 can be formed exclusively in the planet gear pin 6. Alternatively, the oil reservoir 28 can be formed exclusively in the planet carrier 7. In yet another alternative, the oil reservoir
    28 be formed both in the planet carrier 7 and in the planet gear pin 6.
    As can further be seen from FIG. 2, it can be provided that the oil reservoir 28 is flow-coupled to the oil distribution channel section 13 of the first planet carrier cheek 8. In particular, it can be provided that the oil reservoir 28 is interposed between the oil distribution channel section 13 of the first planet carrier cheek 8 and the lubricating oil bore 18 of the planetary radial sliding bearing 14.
    switch. It can thereby be achieved that the oil reservoir 28 during operation
    N2018 / 19600-AT-00
    Cut 13 is constantly filled with lubricating oil during normal operation.
    In a further embodiment variant, not shown, it can also be provided that the oil reservoir 28 is not coupled to the oil distribution channel section 13 of the first planet carrier cheek 8, but is only filled with lubricating oil via the oil reservoir filling channel 29, which will be described in more detail below. In such an embodiment variant, additional lubricating oil bores 18 are arranged in the planetary radial sliding bearing 14, which are coupled to the oil reservoir 28. By means of these additional lubricating oil bores 18, the sliding surface 17 of the planetary radial sliding bearing 14 can be lubricated with oil
    are supplied from the oil reservoir 28.
    As can also be seen from FIG. 2, an oil reservoir filling channel 29 is provided which has an oil reservoir filling opening 30 which extends into the interior 26 within the planetary gear housing 11. The oil reservoir filling channel 29 can be formed in the planet carrier 7 and / or in the planet gear pin 6. The oil reservoir filling opening 30 can be arranged on the planet carrier 7 or on the planet gear pin 6. As can be seen from FIG. 2, the oil reservoir filling opening 30 is designed such that it lies completely below the lubricating oil level 35 or is completely immersed in the oil sump 27 when the respective planet gear pin 6 is in its lowermost position during the rotation of the planet carrier 7.
    Furthermore, an oil collecting element 31 can be provided, which opens in the direction of rotation 32 of the planet gear carrier 7 in the shape of a funnel or shell. The oil collecting element 31 can, for example, be a thin-walled element which has the outer contour of a quarter ball. As a result of the rotation of the planet carrier 7, the lubricating oil located in the lubricating oil sump 27 is pressed into the oil reservoir 28 under additional back pressure by the oil collecting element 31 via the oil reservoir filling channel 29. Due to the shape of the oil collecting element 31, the dynamic pressure occurring during the rotary movement of the planet carrier 7 can be
    are used to achieve an improved filling of the oil reservoir 28.
    N2018 / 19600-AT-00
    Furthermore, it is provided that a check valve 33 is formed, which ensures that lubricating oil can get into the oil reservoir 28 from the oil sump 27
    and can be kept in the oil reservoir 28.
    As can be seen from FIG. 2, it can be provided that the check valve 33 comprises a poppet valve 34, which is designed to close the oil reservoir filling channel 29. As can be seen from FIG. 2, it can be provided that the oil reservoir filling channel 29 has a plurality of bores which are arranged in a drilling pattern distributed around the center line 21 of the planet gear pin 6. The poppet valve 34 may include a plate 36 which is coupled to a guide pin 37. The guide pin 37 is received in a guide bore 38 so as to be axially displaceable. The guide bore 38 can be formed in the planet carrier 7. Furthermore, a spring element 39 can be provided, which extends between an extension 40 of the guide pin 37 and an outer wall 41 of the first planet carrier cheek 8. The plate 36 can be pressed against an inner wall 42 of the first planet carrier cheek 8 by means of the spring element 39. Thus, by means of the plate 36, the oil reservoir filling channels 29 can be
    nenwand 42 of the first planet carrier cheek 8 are closed.
    As can further be seen from FIG. 2, it can be provided that the oil reservoir filling channel 29 extends between the outer wall 41 and the inner wall 42 of the first planet carrier cheek 8. The oil reservoir filling opening 30 can be arranged on the outer wall 41 of the first planet carrier cheek 8. It can further be provided that the oil collecting element 31 on the outer wall 41 of the
    first planet carrier cheek 8 is attached.
    As can also be seen from FIG. 2, the plate 36 is designed so large that it completely closes the oil reservoir filling channel 29 in the closed state. In the arrangement shown, the spring element 39 can have only a slight spring force, since the pressure of the lubricating oil in the oil reservoir 28 acts on the plate 36 and presses it against the inner wall 42 of the first planet carrier cheek 8. The spring element 39 thus only serves to transfer the poppet valve 34 from the open to the closed state and does not need any additional
    Chen absorb loads.
    N2018 / 19600-AT-00
    If there is no pressure in the oil reservoir 28 or the pressure is not completely filled with lubricating oil, when the oil reservoir filling opening 30 is immersed in the oil sump 27, the poppet valve 34 is displaced in the axial direction into its open position and the lubricating oil can flow into the oil reservoir 28 via the oil reservoir filling channel 29 . If the oil reservoir 28 is full or the external pressure of the lubricating oil becomes too low, the poppet valve 34 is opened by means of the spring element.
    tes 39 returned to its closed position.
    FIG. 3 shows a further and possibly independent embodiment of the planet gear pin 6, the same reference numbers or component designations being used for the same parts as in the previous FIGS. 1 and 2. In order to avoid unnecessary repetitions, reference is made to the detailed description in the previous FIGS. 1 and 2.
    sen or referred.
    The embodiment of FIG. 3 is constructed similarly to the embodiment
    game according to FIG. 2.
    As can be seen from FIG. 3, it can be provided that a diaphragm 43 is used as the check valve 33 instead of the poppet valve 34. The membrane 43 can also have a plate 36, which is designed analogously to the plate 36 of the plate valve 34 for closing the oil reservoir filling channel 29. In the case of the membrane 43, the plate 36 can be designed to be flexible, so that it can optionally open the oil reservoir filling channel 29. The spring stiffness of the plate 36 can serve to guide the plate 36 back from its open position to its closed position. The spring stiffness of the plate 36 thus simultaneously acts as a spring element. In Fig. 3 the plate 36 is dashed in
    shown in its open position.
    FIG. 4 shows a further embodiment of the planetary gear pin 6, which is possibly independent of its own, again using the same reference numerals or component designations for the same parts as in the previous ones
    1 to 3 are used. To avoid unnecessary repetitions
    N2018 / 19600-AT-00
    referred to the detailed description in the preceding FIGS. 1 to 3
    or referred.
    As can be seen from FIG. 4, it can be provided that the check valve 33 comprises a flap 44 which, in its closed state, bears against the inner wall 42 of the planet carrier cheek 8. To fill the oil reservoir 28, the flap 44 can be pivoted by means of a swivel joint 45 in order to
    to release the oil reservoir filling channel 29.
    In this embodiment variant, a spring element 39 can also be provided, which serves to bring the flap 44 into its closed position. The spring element 39 can be designed, for example, as a torsion spring,
    which acts directly on the flap 44.
    The exemplary embodiments show possible design variants, it being noted at this point that the invention is not restricted to the specially illustrated design variants of the same, but rather also various combinations of the individual design variants with one another are possible and this variation possibility is based on the teaching of technical action through the present invention Can do that in this technical field
    Expert lies.
    The scope of protection is determined by the claims. However, the description and drawings are to be used to interpret the claims. Individual features or combinations of features from the different exemplary embodiments shown and described can represent independent inventive solutions. The independent inventive solutions
    basic task can be found in the description.
    All information on value ranges in the objective description should be understood to include any and all sub-areas, e.g. the information 1 to 10 is to be understood so that all sub-areas, starting from
    are covered by the lower limit 1 and the upper limit 10, i.e. all
