Description
Schaltklinke Gegenstand der Erfindung ist eine Schaltklinke, die überall @dbrt zu verwenden ist: wo der Schaltvorgang durch plötzlich und schlagartig auftretende Kräfte hervorgerufen wird und frei der zwangsläufig die den Schaltvorgang bewirkende Kraft auch ,gleichzeitig unter Vermittlung der Schaltklinke das Schaltrad o.;dgT. vor Nachlauf sichert. Derartige Schaltvorgänge kommen beispielsweise bei elektromagnetisch gesteuerten Zählwerken, Uhren,, Anzeigewerken, Druckwerken u. dgl. im. Frage. Aber auch bei durch Preßlluft oder *Federkraft usw. bewirkten Schaltungen sind Sicherungen gegen einen Nachlauf notwendig. Ferner ist ein Angleichen oder ein Abstüimmen von bewegender Kraft und bewegter Masse erforderlich. Die esfindmg'smäßige Ausbildung der Schaltklinke vereinigt den Vorteil größter Einfachheit mit dem Vorzug, daß. ein Anpassen von Kraft und! Masse unnötig wird.Pawl The subject of the invention is a pawl that can be used anywhere @dbrt is to be used: where the switching process occurs suddenly and suddenly Forces is generated and free which inevitably causes the switching process Force also, at the same time the ratchet wheel o.; DgT. before overrun. Such switching processes occur, for example, with electromagnetic controlled counters, clocks, display units, printing units and the like. Question. but Even with switching effected by compressed air or * spring force etc. are fuses necessary against an after-run. Furthermore, an adjustment or an adjustment of moving force and moving mass required. The essential training the ratchet combines the advantage of great simplicity with the advantage that. an adjustment of force and! Mass becomes unnecessary.
In der Zeichnung ist,der Exfindungsgegenst.and in einer b,eispielsw(4sen Ausfühxungsform dargestellt, und zwar zeigt Abb. i die Klinke in ,angehobener, Abb. z dieselbe in abgefallener Stellung. Abb.3 zeigt eine andere Ausbildung der Verzahnung.In the drawing, the object of discovery is in a b, e.g. (4sen Embodiment shown, namely Fig. I shows the latch in, raised, Fig. z the same in fallen position. Fig.3 shows a different design of the toothing.
In. -den Abb. i und z ist angenommen,, daß die Klinke unter Wirkung eines Elektromagneten schaltet und unter FeiderwirkMng in die Ausgangslage zurückkehrt. Die Richtungen dieser Kräfte sind durch Pfeile P und p angedeutet.In. - Fig. i and z it is assumed, that the latch is under action an electromagnet switches and returns to the starting position under FeiderffektMng. The directions of these forces are indicated by arrows P and p.
Die Schaltklinke i ist ein Winkelhebel, der an seinem Scheitel: reit ewnem Liängs:sichlpltz z versehen ist, in den ein den Drehpunkt bildender Zapfen 3 eingreift und dessen einer Hebelarm ia als Eingriffszahn ausgebildet ist, während der .andere, iv; zum Angriff der bewegenden KrläfteP und p dient. Die Angriffspunkte ¢ und 5 der Kräfte P und p müssen so gelagert sein, daß der Punkt 5 dem Drehpunkt 3 näher liegt "als der Punkt q..The pawl i is an angle lever that rides at its apex ewnem Liängs: sichlpltz z is provided, in which a pivot forming the pivot point 3 engages and one lever arm of which is generally designed as an engaging tooth, while the .other, iv; serves to attack the moving forces P and p. The points of attack ¢ and 5 of the forces P and p must be positioned so that point 5 is the fulcrum 3 is closer "than the point q ..
Die Wirkungsweise,der Klinke ist folgende: Die Kraft P wird wirksam und! verdrehst, ausgehend von der in der Abb. 2 dargestellten Stellung, die durch Federkraft p niedergehaltene Klinke um den Punkt 3, bis der Arne ia das Schaltrad: (Schaltstange usw.) berührt. Schaltklinke ia und Schaltrad 6 sind somit unter Wirkung der Kraft p gekuppelt. Da eine weitere Drehbewegung nicht möglich ist, die Kraft P aber weiter wirkt, verscläebt sich die Klinke so weit in Richtung !et Kraft P in der Schaltrichtung, als es der Schlitz z, dessen Länge dem gewünschten Schaltweg entspricht, gestattet (Abb. i).The pawl works as follows: The force P becomes effective and! twisted, starting from the position shown in Fig. 2, which by Spring force p held down pawl around point 3 until the Arne ia the ratchet wheel: (Shift rod, etc.) touched. Switching pawl ia and ratchet 6 are thus under effect coupled to the force p. Since a further rotary movement is not possible, the force But if P continues to act, the pawl closes so far in the direction of! Et force P in the switching direction than the slot z, the length of which is the desired switching path is permitted (Fig. i).
Eine Klinke 7 sperrt hierauf dass Schaltrad in dieser Stellung. Eine Üb@erschleuderung des Schaltrades kann nicht stattfinden;, da das Schaltrad mit der Schaltklinke vom Anfang bis zum Ende der Bewegung unter Wirkung der Kraft P gekuppelt war. Hört nach, Vollführen der Schaltbewegung die Kraft P zu wirken auf, so dreht die Federkraft p die Klinke um den Punkt 3, bis der Arm ja an einem Anschlag 8 anliegt. Sodann tritt ein Zurückziehen -der Klinke im, Richtung des Schlitzes a ein, bis die Anfangslage erreicht ist.A pawl 7 then blocks the ratchet wheel in this position. One Overturning of the ratchet wheel cannot take place, because the ratchet wheel with of the pawl from the beginning to the end of the movement under the effect of the force P. was coupled. After completing the switching movement, the force P ceases to act, the spring force p rotates the pawl around point 3 until the arm hits a stop 8 is present. Then there is a retraction of the latch in the direction of the slot a until the starting position is reached.
