Description

Klinkenschalttriebe mit Sperrklinken sind bekannt. Jedoch imiß jede Klinke einzeln betätigt werden, um das Sperrad und die damit in Verbindung stehenden Maschinenteile, z. B. Seiltrommeln, Kettenräder u. dgl., freizugeben. Bei der vorliegenden Ausführung des Sperradgetriebes sind diese Nachteile behoben, da beim Gegeneinanderdrücken der beiden Klinken das Sperrad freigegeben wird.Ratchet shift drives with pawls are known. However, each latch is individually be operated to turn the ratchet wheel and the associated machine parts, z. B. cable drums, sprockets and the like. To release. In the present embodiment of the ratchet gear, these disadvantages are eliminated, since the ratchet wheel is released when the two pawls are pressed against each other will.

Das Wesen des Erfindungsgedankens geht aus den beiliegenden Zeichnungen hervor, und zwar zeigtThe essence of the inventive idea emerges from the accompanying drawings, namely shows

Abb. ι das Getriebe in Verbindung mit einem Betätigungshebel und einer Seiltrommel in zwei Ansichten.Fig. Ι the gear in connection with an operating lever and a cable drum in two views.

Abb. 2 zeigt das Getriebe mit gelösten Klinken und freiem Sperrad.Fig. 2 shows the gearbox with the pawls released and the ratchet wheel free.

In ein Sperrad 1 greift erne Vorschubklinke 2 ein, durch welche die Bewegung des Sperrrades und der damit in Verbindung stehenden Maschinenteile, in dem angenommenen Falle eine Seiltrommel 3, erfolgt. Die Sperrklinke 4 wird durch eine Feder an das Sperrrad gedrückt und legt dieses fest. Soll nun das Sperrad freigegeben werden, so wird der Betätigungsheb el 5 nach rechts gelegt, und die beiden Klinken geben gemäß Abb. 2 beim Aneinanderdrücken das Sperrad infolge der an den Klinken angebrachten Kurven frei. Sobald der Betätigungshebel 5 wieder etwas nach links bewegt wird, treten beide Klinken wieder selbsttätig in Arbeitsstellung. Das Sperrad ist festgelegt und kann wieder durch die Vorschubklinke betätigt werden.A feed pawl 2 engages in a ratchet wheel 1 a, through which the movement of the ratchet wheel and those associated with it Machine parts, in the assumed case a cable drum 3, takes place. The pawl 4 is pressed against the ratchet wheel by a spring and fixes it. If the ratchet wheel is now to be released, then the actuating lever 5 is moved to the right and the two pawls open as shown in Fig. 2 when pressing together the ratchet wheel due to the curves attached to the pawls free. As soon as the operating lever 5 is moved a little to the left again, both step The pawls automatically return to their working position. The ratchet wheel is set and can be used again operated by the feed pawl.
