Description

Es gibt elektrische Drehschalter mit axialem Gesperre, die dachförmige Rastennocken besitzen, von denen der eine mit dem Lagerschild unverdrehbar verbunden und der andere an der Schaltwalze axial verschiebbar angeordnet ist. Bei dem Erfindungsgegenstand bewegt sich der in der Schaltwalze angeordnete verschiebbare Rastnocken in einer zentralen, mehrkantigen Ausnehmung der Schaltwalze und steht unter dem Druck einer axial wirkenden Schraubenfeder, die in einem Versenk des Rastnockens geführt ist.There are electrical rotary switches with an axial lock, the roof-shaped ones Have detent cams, one of which is non-rotatably connected to the end shield and the other is arranged axially displaceably on the shift drum. With the subject of the invention the displaceable latching cam arranged in the shift drum moves in a central, polygonal recess of the shift drum and is under the pressure of a axially acting helical spring which is guided in a countersink of the locking cam.

Ein besonderes Merkmal der Erfindung besteht darin, daß einer der beiden Rastnocken oder auch beide aus einem Graphit enthaltenden Preßstoff hergestellt sind. Der mit dem Lagerschild verbundene Rastnocken greift mit Vorsprüngen in das letztere bzw. besteht mit diesem aus einem Teil.A special feature of the invention is that one of the two locking cams or both made of a graphite-containing molded material are. The locking cam connected to the end shield engages with projections in the the latter or consists of one part with this.

In der Abb. i ist die Schaltwalze mit den Rastnocken im Längsschnitt dargestellt. Die Abb. 2 zeigt eine Ansicht des Rastnockens mit der Schaltwalze von innen und die Abb. 3 den mit dem Lagerschild verbundenen Rastnocken.In Fig. I, the shift drum with the locking cams is in a longitudinal section shown. Fig. 2 shows a view of the locking cam with the shift drum of inside and Fig. 3 shows the locking cam connected to the end shield.

Die Schaltwalze i (Abb. i) ist mit der Achse 2 durch den Vierkant 3 unverdrehbar verbunden. In einer mehrkantigen Ausnehmung 4 der Schaltwalze i (Abb. 2) ist der Rastnocken 5 längs verschiebbar angeordnet. Er steht unter dem Druck der Schraubenfeder 6, welche in der Ausnehmung 7 (Abb. 2) des Rastnockeng 5 sich bewegt. Sie drückt den Rastnocken 5 gegen den mit dem Lagerschild 8 verbundenen Rastnocken 9. Um eine besondere Schmierung und Wartung der Verrastung zu vermeiden, besteht der Rastnocken 5 aus einem Graphit enthaltenden Preßstoff. Im Sinne der Erfindung ist es aber einerlei, ob der Rastnocken 5 oder 9 bzw. beide aus diesem Stoff bestehen. Der Rastnocken 9 wird durch die vorspringenden Nocken io bzw. i i in dem Lagerschild 8 gehalten. Er kann aber auch mit dem letzteren aus einem Teil bestehen.The shift drum i (Fig. I) is with the axis 2 through the square 3 non-rotatably connected. In a polygonal recess 4 of the shift drum i (Fig. 2) the locking cam 5 is arranged to be longitudinally displaceable. He's under pressure the coil spring 6, which in the recess 7 (Fig. 2) of the locking cam 5 itself emotional. It presses the locking cam 5 against the one connected to the end shield 8 Latching cams 9. To avoid special lubrication and maintenance of the latching, the locking cam 5 consists of a graphite-containing molded material. In the sense of the Invention, however, it does not matter whether the locking cam 5 or 9 or both from this Consist of substance. The locking cam 9 is io and i by the protruding cams i held in the end shield 8. But it can also be made from one part with the latter exist.

PATENTANSPRÜCHE: i. Drehschalter für Wechselstrom mit axialem Gesperre und dachförmigen Rastnocken, von denen einer mit dem Lagerschild unverdrehbar verbunden und der andere axial verschiebbar in der Walze angeordnet ist, dadurch gekennzeichnet, daß in der mit der Achse unverdrehbar verbundenen Schaltwalze der axial verschiebbare Rastnocken sich in einer zentralen mehrkantigen Ausnehmung der Schaltwalze bewegt und unter dem Druck einer axial wirkenden Schraubenfeder steht, die in einem Versenk des Rastnockens geführt ist. PATENT CLAIMS: i. Rotary switch for alternating current with axial locking and roof-shaped locking cams, one of which is non-rotatably connected to the end shield and the other is arranged axially displaceable in the roller, characterized in that the axially displaceable locking cam is polygonal in a central polygon in the switching drum connected to the axis so that it cannot rotate Moved recess of the shift drum and is under the pressure of an axially acting helical spring which is guided in a countersink of the locking cam. 2.
