    Description: The invention relates to a drive arrangement for a vertical roller mill according to the preamble of claim 1.
    From DE 10 2011 079 555 A1 a drive arrangement for a vertical roller mill is known. Thus, the known from this prior art drive assembly for a vertical roller mill comprises a housing, a rotatably supported on the housing pressure plate which is rotatable about a vertical pressure plate axis and which forms an output of the drive assembly, a transmission device which is below the pressure plate in the Housing is arranged and which is in rotational drive connection with the pressure plate, and a plurality of electric motors, which are arranged below the transmission device in the housing, wherein each electric motor has a parallel and radially offset from the pressure plate rotation axis extending rotor axis of rotation. The gear arrangement of the drive arrangement according to DE 10 2011 079 555 A1 comprises at least one, preferably two, planetary gear and additionally a spur gear with a central gear, each electric motor having a with the central gear of the spur gear engaged pinion. Starting from the spur gear, the drive torque provided by the electric motors is transmitted via the or each planetary gear in the direction of the pressure plate. The drive torque provided by the electric motors is accordingly summed on the drive side on the central wheel of the spur gear and then transmitted via the or each planetary gear to the driven-side pressure plate.
    There is a need for a drive assembly for a vertical roller mill with a simpler structure.
    On this basis, the invention is based on the object to provide a novel drive arrangement for a vertical roller mill. This object is achieved by a drive arrangement for a vertical roller mill according to claim 1. According to the invention, each electric motor drives via a plurality of radially offset from the respective rotor rotational axis, only fixed to the housing fixed gear shafts in a common for all electric ring gear, which is in rotational drive connection with the pressure plate.
    In the inventive drive arrangement, the drive torque provided by the electric motors is summed only on the output side on the ring gear, which is coupled to the pressure plate. The inventive drive arrangement is completely without planetary gear. All transmission shafts, via which the electric motors drive their drive torque into the common ring gear, are fixed to the housing of the drive arrangement. Thereby, a drive arrangement for a vertical roller mill can be provided with a simple structure. The bearings can be stationary, which facilitates their lubrication and monitoring.
    According to an advantageous embodiment of the invention drives each electric motor via a positioned on its respective rotor axis of rotation drive pinion in each case a first gear, which together with a second gear on a respective electric motor associated, radially offset from the respective rotor axis of rotation extending first fixed to the housing Transmission shaft is arranged. Each electric motor drives in each case via a third gear, which is arranged together with a fourth gear on a respective electric motor associated, radially offset from the respective rotor axis extending second, fixed to the housing gear shaft, in the common ring gear. This structure allows a transmission of the torque provided by the electric motors in the common ring gear. With three gear stages, this design does not require a rotating planet carrier.
    Preferably, each second gear is in engagement with the respective fourth gear, so therefore each electric motor on the electric motor-individual first and second transmission shafts and the electric motor-individual first, second, third and fourth gears in the common, driven-side ring gear drives. As a result, the structure of the drive arrangement can be further simplified.
    Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be described, without being limited thereto, with reference to the drawing. Showing:

    All electric motors 14 common ring gear 18 is therefore in direct drive connection with the pressure plate 11 and rotates with the pressure plate 11. All gear shafts 16, 17, via which the electric motors 14 drive their torque into the common ring gear 18, are mounted fixed to the housing. The drive arrangement accordingly has no shaft rotating in the housing 10. The summation of the torque provided by the electric motors 14 takes place on the output side directly on the ring gear 18 coupled to the pressure plate 11. Each electric motor 14 drives a respective first gearwheel via a drive pinion 19 positioned on its respective rotor axis 15 or its respective drive shaft 25 20, which is arranged together with a second gear 21 on a respective electric motor 14 associated, radially offset from the respective rotor axis 15 extending first electric motor, fixed housing fixed gear shaft 16. An axis of rotation 22 of these transmission shafts 16 is fixed to the housing. Furthermore, the axes of rotation 22 of the first transmission shafts 16 extend radially offset to the rotor axes of rotation 15 of the electric motors 14 and radially offset to the pressure plate rotation axis 12. Each electric motor 14 drives via a third gear 23, which together with a fourth gear 24 on a respective electric motor 14 associated , radially offset from the respective rotor axis of rotation 15 extending second electric motor-individual, fixed to the housing fixed gear shafts 17 is disposed in the common ring gear 18 a.

Furthermore, these axes of rotation 25 of the second transmission shafts 17 extend radially offset from the axes of rotation 22 of the first transmission shafts 16 and radially offset from the rotor axes of rotation 15 of the electric motors 14 and radially offset to the pressure plate rotation axis 12. [0014] Each second gear 21 is connected to the respective fourth gear 24 engaged. Starting from each electric motor 14, the torque provided by the respective electric motor 14 is accordingly transmitted to the respective first gear shaft 16 via the respective drive pinion 19, which is directly in engagement with the respective first gear 20, wherein the respective second gear 21, which with the respective fourth gear 24 is directly engaged, transmits this torque, starting from the respective first transmission shaft 16 to the respective second transmission shaft 17. The third gear 23 accommodated on the respective second gear shaft 17 transmits the respective torque to the common ring gear 18, so that the torques provided by the electric motors 14 are summed in the area of the ring gear 18, ie directly on the output side of the pressure plate 11 providing the output of the drive arrangement which is fixedly connected to the ring gear 18. As already stated, all rotor axes of rotation 15 of the electric motors 14, all the electric motors 14 associated shafts 16, 17 and all carried by the shafts gears 20, 21, 23, 24 and the ring gear 18 mounted fixed to the housing, none of these elements runs accordingly on the housing 10 to.

Particularly preferably, the drive assembly is when the same six (N = 6) electric motors 14, six first transmission shafts 16, six second transmission shafts 17 and a common ring gear 18 has. So that the gears 24 find place on the pitch circle of the transmission axes of the second stages 25, the first, third, fifth ... wheels 25 are offset in height to the second, fourth, sixth .... wheels 25th arranged. In order to allow the most space-saving arrangement of the transmission shafts 16, 17 and the gear shafts 16, 17 carried gears 20, 21, 23, 24 in the housing 10 of the drive assembly, diametrically opposed electric motors 14 are the respective gears 20th , 21, 23, 24 of the gear shafts 16, 17 are interchanged in relative arrangement with respect to each other such that in the region of a first electric motor 14 of two diametrically opposed electric motors, the second gear 21 above the first gear 20 and thus the fourth gear 24 above the first gear 20 is arranged, whereas on a second electric motor 14 of two diametrically opposed electric motors, the fourth gear 24 and the second gear 21 are respectively disposed below the first gear 20. By this offset, a particularly space-saving design of the inventive drive arrangement can be provided, which can transmit the necessary torques. The inventive drive arrangement has a simple structure. All shafts are fixed to the housing and therefore do not run around in the housing. The summation of the torques provided by the electric motors 14 takes place on the output side directly on the ring gear 18 which is coupled to the pressure plate 11 and is common to all electric motors 14. The drive arrangement according to the invention is characterized not only by a simple structure but also by a high degree of redundancy.
