Abstract

The swashplate is positioned not on the rotor shaft (4), but is centered in a pref. ring-shaped guide (3), by three or more guide webs (2). The swashplate has an outer ring (1), and the balls are connected from the inside.

Description

Die Erfindung betrifft einen Modellhubschrauber mit einem Rotorkopf, der über eine Taumelscheibe angesteuert wird.The invention relates to a model helicopter with a rotor head that over a swashplate is driven.

Ein Hubschrauber besitzt in der Regel einen Hauptrotor und einen Heckrotor. Die Steuerung des Hubschraubers um die Längs- und Querachse sowie meist auch die Vertikalbewegung (Steigen und Sinken) werden durch Anstellwinkeländerungen der einzelnen Rotorblätter bzw. indirekt durch Ansteuern der Hilfsrotorblätter (Hillerpaddel) bewirkt. Die Übertragung dieser mechanischen (zyklischen und / oder kollektiven) Steuerbewegungen von der Mechanik auf den, über die Rotorwelle verbundenen, sich in Rotation befindenden, Rotorkopf erfolgt durch eine Taumelscheibe. Solch eine Taumelscheibe besteht meist aus einem mitlaufenden (5) und einem sich nicht mitdrehendem (1) Teil, welche miteinander, z. B. durch ein Kugellager (10), verbunden sind. Die Taumelscheibe wird, meist durch ein Kugelgelenk zwischen mitlaufendem Teil (5) und Rotorwelle (4), auf der Rotorwelle gelagert. Die von der Mechanik kommenden Steuergestänge sind am nicht mitdrehenden Teil (1 ), die zum Rotorkopf weiterführenden Gestänge am mitlaufenden Teil (5), angebunden. Diese Anbindung geschieht meist durch Kugelgelenke. Wir nun die Taumelscheibe durch die Steuergestänge vertikal verschoben, bzw. horizontal gekippt überträgt sie diese Bewegungen, auf den Rotorkopf, ohne dessen Rotationsbewegung zu blockieren.A helicopter usually has a main rotor and a tail rotor. The control of the helicopter about the longitudinal and transverse axis and usually also the vertical movement (rising and falling) are effected by changing the angle of attack of the individual rotor blades or indirectly by controlling the auxiliary rotor blades (Hiller paddle). The transfer of these mechanical (cyclic and / or collective) control movements from the mechanics to the rotor head, which is connected via the rotor shaft and is in rotation, takes place by means of a swash plate. Such a swashplate usually consists of a moving ( 5 ) and a non-rotating ( 1 ) Part, which with each other, e.g. B. by a ball bearing ( 10 ), are connected. The swashplate is, usually by a ball joint between the moving part ( 5 ) and rotor shaft ( 4 ), mounted on the rotor shaft. The control rods coming from the mechanics are on the non-rotating part ( 1 ), the linkage leading to the rotor head on the moving part ( 5 ), connected. This connection is usually done by ball joints. If the swashplate is moved vertically by the control linkage or tilted horizontally, it transfers these movements to the rotor head without blocking its rotational movement.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diese Taumelscheibe hinsichtlich der Herstellungskosten und der konstruktionsbedingt auftretenden Wegdifferenz zu verbessern.The present invention lies based on the task of this swashplate in terms of manufacturing costs and to improve the path difference due to the design.

Zur Lösung dieser Aufgabe führt, das der nicht mitlaufende Teil der Taumelscheibe durch drei oder mehr Zentrierungsstege in einer, vorzugsweise ringförmigen Führung, zentriert wird. Dadurch kann auf ein zentrales Kugelgelenk verzichtet werden.This leads to the solution of this task the non-rotating part of the swashplate by three or more Centering webs in a, preferably annular guide, is centered. Thereby there is no need for a central ball joint.

Mit dieser Erfindung wird erreicht, dass die Herstellungskosten der Taumelscheibe, zum einen durch den Wegfall des Kugelgelenks, zum anderen durch den Wegfall eines Arbeitsschrittes (Montage des Kugelgelenks) erheblich gesenkt werden.With this invention it is achieved that the manufacturing cost of the swashplate, on the one hand, by the Elimination of the ball joint, on the other hand by the elimination of one work step (Assembly of the ball joint) can be significantly reduced.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 angegeben. Hierbei werden die Kugelgelenke der zum Außenring führenden Gestänge von innen her angebunden. Dadurch wird der Abstand 6 zwischen den Kugelgelenken des Innen- und Außenringes auf ein Minimum reduziert. Die, konstruktionsbedingt entstehende, Hebelarmdifferenz zwischen Innenring (L1) und Außenring (L2) wird somit ebenfalls minimiert. Aus dieser Neuerung resultiert eine wesendlich geringere Wegdifferenz zwischen eingehender und zum Rotorkopf weiterführender Steuerbewegung.An advantageous embodiment of the invention is specified in the protection claim 2. The ball joints of the rods leading to the outer ring are connected from the inside. This will make the distance 6 reduced to a minimum between the ball joints of the inner and outer ring. The lever arm difference between the inner ring (L1) and outer ring (L2), which is caused by the design, is also minimized. This innovation results in a substantially smaller path difference between the incoming control movement and the control movement continuing to the rotor head.

Ein Ausführungsbeispiel der Erfindung wird anhand 1 erläutert. Der Taumelscheibenaußenring 1 wird durch drei Zentrierungsstege 2, in einer ringförmigen Führung 3, zur Rotorwelle 4 zentriert. Die Anlenkkugeln 7 des Außenrings 1 sind, nach Schutzanspruch 2, von innen, an einem Ring 9, angebunden. Dadurch wird der Abstand 6 zu den Anlenkkugeln 8 des Innenrings 5 minimiert.An embodiment of the invention is based on 1 explained. The swashplate outer ring 1 is through three centering bars 2 , in an annular guide 3 , to the rotor shaft 4 centered. The pivot balls 7 the outer ring 1 are, according to protection claim 2 , from the inside, on a ring 9 , connected. This will make the distance 6 to the pivot balls 8th of the inner ring 5 minimized.

2: Die Taumelscheibe kann im Führungsring sowohl vertikal verschoben, wie auch um die Quer- und Längsrichtung geneigt werden. 2 : The swashplate can be moved vertically in the guide ring, as well as inclined in the transverse and longitudinal direction.
