  • Publication number: 20240117867
    Abstract: Disclosed is a drive train having a drive shaft of a driven machine, a drive machine, and a differential transmission with three drives or outputs, wherein one output can be connected to the drive shaft, a first drive can be connected to the drive machine, and a second drive can be connected to a differential drive. The differential drive is connected to the second drive via an adjusting gear system with gears, and the drive shaft is connected to the output via an output gear system with gears. Viewed from the drive machine in the direction of the axis of the drive shaft, the gears of the adjusting gear system project at least as far as into the area of the gears of the output gear system.

  • Publication number: 20230318494
    Abstract: Disclosed is a method for connecting an electric asynchronous machine of a powertrain to an electric grid. The powertrain has a machine driveshaft, the drive machine, a differential drive, and a differential transmission with three drives or outputs. One output connects to the driveshaft, a first drive connects to the drive machine, and a second drive connects to the differential drive. In a first phase, the drive machine starts up while one drive is simultaneously connected to the other drive or to the output, and the drive machine is separated from the grid. In a second phase, the drive machine connects to the grid, the connection between the one drive and the other drive or the output is separated, and the rotational speed of a drive/output is ascertained. The drive machine is connected to the grid if its rotational speed deviation from the grid frequency <±5.0%.

  • Patent number: 10006439
    Abstract: An energy production plant has a drive train including a differential gear (14) with three drive and power take-off assemblies, a first drive assembly being connected to a drive shaft, a power take-off assembly being connected to a generator (13) and a second drive assembly being connected to a differential drive assembly (16). The differential gear (14) is a planetary gear. Both an emergency brake (4) and a service brake (20) are located in the drive train. In the event of a power failure, grid fault or an emergency shutdown, the service brake (20) is activated such that the torque acting on the rotor (1) supplied by the drive train remains substantially constant for a period of at least 0.5 seconds.
