ROTOR BLADE COUPLING DEVICE AND ROTOR HEAD

摘要

A rotor blade coupling device (9) comprising a torsionally rigid carrier (4) is disclosed, the carrier (4) being mounted in a manner which is free of centrifugal force between a thrust bearing (3) and a control bearing (5), resilient impact and pivoting movements of the rotor blade coupling device (9) being able to take place in a damped manner. The rotor blade coupling device (9) is clamped between a rotor head star (101) and a rotor head central piece (102) and held rotatably about the rotor axis A. The centrifugal forces which occur, are transmitted from a rotor blade holder (2) to the rotor head star (101) and thus kept away from the carrier (4).

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 a tensile element (48) is arranged running between the thrust bearing (3) and the control bearing (5) and fully traversing the carrier (4) of loop-like configuration.
