Abstract:
1. A rotor blade coupling device ( 9 ) comprising a carrier ( 4 ) and a rotor blade holder ( 2 ) fastened thereto for receiving at least one rotor blade ( 103 ), wherein the carrier ( 4 ) is torsionally rigid and is mounted to be able to be resiliently deflected in a manner which is free of centrifugal force between a thrust bearing ( 3 ) and a control bearing ( 5 ) in the pivoting and impact directions, centrifugal forces being able to be transmitted by the rotor blade coupling device ( 9 ) to a torque transmission unit ( 1 ) and the entire rotor blade coupling device ( 9 ) being pivotably mounted without torsion about a carrier longitudinal axis (B) and wherein the carrier ( 4 ) is connected to the rotor blade holder ( 2 ) and the thrust bearing ( 3 ) via a flange on the blade holder side ( 8 ).
