Abstract
In a device for transmitting optical signals between a first subassembly and a second subassembly, which rotatable about an axis relative to the first subassembly. The first subassembly includes a first optical waveguide, and the second subassembly includes a second optical waveguide. The device includes a first sleeve enclosing the first optical waveguide, a first bushing enclosing the first sleeve, a housing, a second sleeve enclosing the second optical waveguide, a second bushing enclosing the second sleeve. Furthermore, the device includes a bearing arrangement, including at least one first ring and rolling elements, rollingly supported on a conical surface. The housing encloses the first bushing, the second bushing, and the bearing arrangement, the bearing arrangement is axially displaceable relative to the housing, and the second bushing is axially preloaded with respect to the first bushing via the bearing arrangement. The rolling elements are radially preloaded with respect to the housing by their support on the conical surface.
