  Vorrichtung zur Axialverschiebung der durch   Schraubenräder   angetriebenen Steuer- 
Es wurde bei Brennkraftmaschinen bereits vorgeschlagen, zwecks Änderung der zu steuernden
Arbeitsphasen die Steuernockenwelle durch Vermittlung ihrer   Antriebsschraubenräder   axial zu ver- schieben. 



   Gegenstand der Erfindung ist eine weitere Ausgestaltung dieser Anordnung und ihr wesentliches
Kennzeichen besteht darin, dass die Axialverschiebung durch eine gegen die Wellenstirnfläche und der
Axialreaktion der   Antriebsschraubenräder   entgegenwirkende Kraft erfolgt. Diese Anordnung hat den wesentlichen Vorzug, dass das auf die Wellenstirnfläehe wirkende Organ zugleich das Abstützen der vom Schraubenradantrieb   herrührenden   Axialreaktion besorgt. 



   In der Zeichnung bezeichnet a die Steuernockenwelle, die durch Räder   e, f mit schraubenförmiger   Verzahnung angetrieben wird. Verschiebt man die Welle   a   axial in der einen oder in der anderen Richtung, so erleidet die Welle durch Vermittlung ihrer   Antriebsschraubenräder   eine von der Steigung der Schrauben- zähne und den Durchmessern der Schraubenräder abhängige Winkelverdrehung, die eine entsprechende Änderung der gesteuerten Arbeitsphasen mit sich bringt.

   Zu diesem Zwecke ist an dem Ende der Welle a, nach welchem sich der von den Schraubenradzähnen herrührende Axialschub geltend macht, ein Stütz-   lager g   (beispielsweise unter Zwischenschaltung von Kugeln h) angeordnet, welches den Axialschub auf einen kolbenförmigen Teil i überträgt, der, ohne an der Drehung teilzunehmen, in einem zylinder- artigen Gehäuse 1 gleiten kann, das zugleich zur Führung und zum Tragen des   Wellenendes   dient. Mit m ist ein kurzer Bolzen bezeichnet, gegen den zwecks Axialverschiebung der Welle a und entsprechender
Verdrehung der Nocke b entweder ein Fliehkraftregler (wenn dies selbsttätig erfolgen soll) oder ein Handhebel n wirkt, dessen Sperrklinke o in einen Zahnsektor p eingreift.

  Device for the axial displacement of the control gear driven by helical gears
It has already been proposed in internal combustion engines to change the to be controlled
Working phases to move the control camshaft axially by means of its drive screw wheels.



   The invention relates to a further embodiment of this arrangement and its essentials
It is characterized by the fact that the axial displacement is caused by an against the shaft face and the
Axial reaction of the drive helical gears counteracting force takes place. This arrangement has the essential advantage that the member acting on the shaft end face also supports the axial reaction resulting from the helical gear drive.



   In the drawing, a denotes the control camshaft, which is driven by gears e, f with helical teeth. If the shaft a is shifted axially in one or the other direction, the shaft undergoes an angular rotation which is dependent on the pitch of the helical teeth and the diameters of the helical gears through the intermediary of its drive helical gears, which results in a corresponding change in the controlled working phases.

   For this purpose, a support bearing g (for example with the interposition of balls h) is arranged at the end of the shaft a, after which the axial thrust originating from the helical gear teeth is applied, which transfers the axial thrust to a piston-shaped part i which, without participating in the rotation, can slide in a cylinder-like housing 1, which serves both to guide and to support the shaft end. With m a short bolt is designated, against which for the purpose of axial displacement of the shaft a and the like
Rotation of the cam b either a centrifugal governor (if this is to take place automatically) or a hand lever n acts, whose pawl o engages in a tooth sector p.
