  • Shaft-hub connection for a transmission
    Patent number: 12669112
    Abstract: A shaft-hub connection for a planetary transmission includes a shaft, a hub element surrounding an outer circumference of the shaft and drivingly connected to the shaft for rotation about a main rotation axis via splines, a housing element fixed with respect to the main rotation axis, and an oil channel extending in the housing element and the hub element and designed to open out in a region of the splines to supply at least the splines with lubricating oil for oiling. The oil channel forms between the housing element and the hub element a lubrication gap for transferring lubricating oil and extends radially from inside outwards in a region of the lubrication gap.
    Type: Grant

  • Planetary transmission having an improved lubricant supply, drive train and wind turbine
    Patent number: 12578011
    Abstract: A planetary transmission includes first and second planetary stages. At least one of the first and second planetary stages includes a transmission component. The planetary transmission further includes a pilot bearing, and a double-walled pipe received in the pilot bearing and having a central portion designed to have an outlet point for dispensing lubricant into the transmission component. A bushing is disposed in a region of the outlet point such that a gap is formed between the bushing and the transmission component.
