Claims (2)

1. Hubschrauber-Dreiblattrotorkopf mit Dämpfung der Rotorblätter/ Rotorblattlager, dadurch gekennzeichnet, daß die Rotorblätter im Rotorkopf so gelagert sind, daß sie frei nach oben und unten schwingen können, und daß die Schwingung eines Rotorblattes über einen Hebel auf einen Ring und von diesem wiederum über Hebel auf die anderen Rotorblätter übertragen wird. Die Hebel sind aus technischen Gründen drehbar in den Wellen der Rotorblätter gelagert (Drehebene tangential zur Rotorebene), die Drehung der Hebel wird jedoch in den Lagern durch Kunststoffdämpfer begrenzt. Ebenso wird die Gesamt­ schwingung des Systems dadurch eingeschränkt, daß obengenannter Ring über ein elastisches Kunststoff-/Gummilager mit der Rotorwelle verbunden ist.1. Helicopter three-bladed rotor head with damping of the rotor blades / rotor blade bearing, characterized in that the rotor blades are mounted in the rotor head so that they can swing freely up and down, and that the vibration of a rotor blade via a lever on a ring and this in turn is transferred to the other rotor blades via levers. For technical reasons, the levers are rotatably mounted in the shafts of the rotor blades (plane of rotation tangential to the rotor plane), but the rotation of the levers is limited in the bearings by plastic dampers. Likewise, the overall vibration of the system is limited in that the above ring is connected to the rotor shaft via an elastic plastic / rubber bearing. 2. Rotorkopf nach Schutzanspruch 1 dadurch gekennzeichnet, daß sich im Rotorkopfsystem über der Taumelscheibe (Scheibe zur Anlenkung der Blattverstellung) ein dreiarmiges mechanisches Element befindet das über jeweils drei Kipphebel die Neigung der Taumelscheibe auf die einzelnen Rotorblätter überträgt. Das Heben und Senken des Elements entlang der Rotorwelle bewirkt ebenfalls über die Hebel eine gleichmäßige Verstellung aller drei Rotorblätter. (Dieser mechanische Teil ist nur notwendig bei Rotorkopfanlenkungen vom der Art des Herstellers Kyosho in Verbindung mit einem Dreiblattrotorkopf.)2.Rotor head according to protection claim 1 characterized, that in the rotor head system above the swash plate (plate for articulation the blade adjustment) a three-armed mechanical element is located above three rocker arms each the inclination of the swash plate on the individual rotor blades transmits. The element is raised and lowered along the rotor shaft also an even adjustment of all three rotor blades via the levers. (This mechanical part is only necessary for rotor head linkages from the Type of manufacturer Kyosho in connection with a three-bladed rotor head.)
