  • Patent number: 10731747
    Abstract: A gear device with a housing and a structural component rotatably mounted at the housing by a bearing that delimits a housing interior space. The gear device has a hydraulic fluid supply line for supplying hydraulic fluid into the interior space. A gap provides sealing between the housing and structural component. The gap is arranged radially between the housing and a further rotatable structural component or between a further housing and the structural component. A further bearing rotatably mounts the further structural component in the area of the housing or rotatably mounts the structural component at the further housing. An appliance couples the further structural component to the structural component or couples the housing to the further housing, and facilitates a relative movement between the further structural component and the structural component or between the housing and the further housing in the axial and/or radial directions.
