Description

Nockenschalter für unterschiedliche Einbauräume Die Erfindung betrifft einen Nockenschalter für unterschiedliche Einbauräume mit einer im Zentrum des Schalters gelagerten, die Nockenräder und Rastenteile tragenden profilierten Hülse, in der eine durchgehende Schaltachse steckt.Cam switches for different installation spaces The invention relates to a cam switch for different installation spaces with one in the center of the switch bearing profiled sleeve bearing the cam wheels and detent parts, in the a continuous switching axis is stuck.

Es ist wichtig, daß Nockenschalter mit verschieden langen Achsen gebaut werden können, um den mannigfachen Einbauverhältnissen gerecht zu werden. Bei den zur Zeit bekannten Nockenschaltern, die von einer durchgehend profilierten Schaltachse durchdrungen werden, ist es üblich, je nach Bedarf verschieden lange Schaltachsen vorzusehen. Diese Bauweise ist sehr umständlich und kostspielig, da der Hersteller eine Vielzahl von Schaltachsen verschiedener Länge am Lager halten muß. Auch die Nokkenschalter verarbeitende Industrie muß, um allen Bedarfsfällen Rechnung zu tragen, ein großes Lager an Nockenschaltern mit verschieden langen Schaltachsen führen.It is important that cam switches are built with axes of different lengths can be to meet the manifold installation conditions. Both currently known cam switches that have a continuously profiled switching axis are penetrated, it is common to have shift axes of different lengths as required to be provided. This construction is very cumbersome and expensive because of the manufacturer must keep a variety of shift shafts of various lengths in stock. Also the The cam switch manufacturing industry must, in order to meet all requirements, have a large stock of cam switches with switching axes of different lengths.

Diese Mängel können bei einem eingangs beschriebenen Schalter erfindungsgemäß dadurch behoben werden, daß die Schaltachse mit einer durchgehenden Bohrung mit Innengewinde versehen ist, in das eine Verstellschraube eingreift, deren Kopf in der hinteren Lagerbuchse steckt und von der Abschlußplatte gehalten wird, die beim Drehen die Schaltachse in ihrer Längsrichtung verschiebt und nach Beendigung der Drehung in ihrer Lage festhält.According to the invention, these deficiencies can be found in a switch described at the outset be remedied by the fact that the switching axis with a through hole with Internal thread is provided, in which an adjusting screw engages, the head of which in the rear bearing bush is inserted and held by the end plate, which when Turning the switching axis moves in its longitudinal direction and after completing the Rotation holds in place.

Bei diesem neuen Nockenschalter kann somit die erforderliche herausragende Achslänge genau eingestellt werden. Die verschiebbare Achslänge bei Normalschaltern ist begrenzt durch die Schalterlänge selbst, doch kann, wenn eine überlänge erforderlich ist, die Schaltachse leicht von außen ohne Demontage des Schalters gegen eine längere ausgewechselt werden.With this new cam switch, the required outstanding Axle length can be set precisely. The adjustable axis length for normal switches is limited by the switch length itself, but can if an excess length is required is, the switching axis easily from the outside without dismantling the switch against a longer one be replaced.

Es sind zwar elektrische Kontaktgeber bekannt, deren Schaltwelle verschiebbar in einer programmscheibentragenden Hülse angeordnet ist, doch dient bei diesen Geräten die Schiebebewegung der Hülse zur Kontaktbetätigung und nicht etwa zur Einstellung verschiedener Achslängen. Bei diesen Geräten wird die Schaltachse in ihrer Länge nicht verschoben, sondern nur gedreht, wobei sich die Hülse in axialer Richtung auf der Achse hin und her bewegt.Although electrical contactors are known, the switching shaft of which can be displaced is arranged in a program disk-carrying sleeve, but is used in these devices the sliding movement of the sleeve for contact actuation and not for setting different axis lengths. With these devices, the switching axis is in length not shifted, but only rotated, with the sleeve in the axial direction moved back and forth on the axis.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Figur zeigt einen Schnitt des Schalters gemäß der Erfindung durch seine Mittelebene.An exemplary embodiment of the invention is shown in the drawing. The figure shows a section of the switch according to the invention through its central plane.

In dem Ausführungsbeispiel bedeutet 1 eine außen profilierte Schaltachse, die in einer Hülse 2 gleichen Profils aufgenommen wird. Die Hülse 2 ist an ihren Enden in die Lagerbuchsen 3 und 4 eingesteckt, welche in den Abschlußplatten 5 und 6 gelagert sind. Auf der durchgehenden Hülse 2 sitzen die Nockenräder 7, die Anschlagscheiben 8 und die Rastung 9.In the exemplary embodiment, 1 means an externally profiled switching axis, which is received in a sleeve 2 with the same profile. The sleeve 2 is inserted at its ends into the bearing bushes 3 and 4 , which are mounted in the end plates 5 and 6. The cam wheels 7, the stop disks 8 and the detent 9 are seated on the continuous sleeve 2.

Die Schaltachse 1 ist mit einer durchgehenden Bohrung mit Innengewinde 10 versehen. In dieser Bohrung mit Innengewinde 10 läuft die Verstellschraube 11. Der Schraubenkopf 12 dieser Verstellschraube 11 wird in der Lagerbuchse 3 aufgenommen und von der Abschlußplatte 5 in seiner Lage gehalten. Durch die Bohrung 13 in der Abschlußplatte 5 kann die Verstellschraube 11 gedreht werden. Durch Drehung der Verstellschraube 11 wird die Achse 1 je nach Drehrichtung aus dem Schalter heraus- oder in den Schalter hineingeschoben und in der Einstellänge festgehalten.The switching axis 1 is provided with a through hole with an internal thread 10. The adjusting screw 11 runs in this bore with an internal thread 10. The screw head 12 of this adjusting screw 11 is received in the bearing bush 3 and held in its position by the end plate 5. The adjusting screw 11 can be rotated through the bore 13 in the end plate 5. By turning the adjusting screw 11 , the axis 1 is pushed out of the switch or into the switch, depending on the direction of rotation, and held in the setting length.

Genügt die verstellbare Länge der Schaltachse 1 nicht, kann eine noch längere Schaltachse nach Herausdrehen der Schaltachse 1 von außen durch die Lagerbuchse 4 in die Profilhülse 2 eingeschoben werden.If the adjustable length of the switching axis 1 is not sufficient, an even longer switching axis can be inserted from the outside through the bearing bushing 4 into the profile sleeve 2 after the switching axis 1 has been unscrewed.
