Description

Anordnung des Kurbelzapfens an Sägegattern. Bisher wurden die Kurbelzapfen für Sägegatter und ähnliche Maschinen in der Kurbel bzw. Kurbelscheibe angeordnet und die Schubstange mit einem Lagerauge auf den Zapfen gesetzt. Durch diese Bauart ergibt sich ein Schubstangenkopf von großen Abinessungen, was besonders bei Maschinen von Bedeutung ist, die große Kräfte zu übertragen haben, weil dann auch der Kurbelzapfen einen erheblichen Durchmesser haben muß. Durch diesen großen Schubstangenkopf wird einerseits die Anfertigung der Schubstange sehr erschwert und erheblich verteuert, anderseits wird für den umlaufenden Schubstangenkopf viel Raum beansprucht, und es ergibt sich eine große Schwungmasse, wodurch die Umlaufszahl begrenzt wird.Arrangement of the crank pin on the saw frame. Previously the crank pins were for saw frames and similar machines in the crank or crank disk and the push rod is placed on the pin with a bearing eye. With this design the result is a push rod head of large dimensions, which is especially true for machines What is important is that the great forces have to be transmitted, because then the crank pin too must have a considerable diameter. This large push rod head makes on the one hand, the production of the push rod is very difficult and considerably more expensive, on the other hand, a lot of space is required for the rotating push rod head, and the result is a large centrifugal mass, which limits the number of revolutions.

Gegenstand der Erfindung ist nun eine Anordnung des Kurbelzapfens, die im wesentlichen sich dadurch kennzeichnet, daß der Zapfen am Ende der Schubstange befestigt und sein Lager in der Kurbel untergebracht ist. Dadurch erhält man einen Schubstangenkopf von geringen Abmessungen, und selbst Kugellager für den Zapfen können ohne Mehrbedarf an Raum in der Kurbel untergebracht, dort geschützt und abgedichtet werden.The subject of the invention is now an arrangement of the crank pin, which is essentially characterized in that the pin at the end of the push rod attached and its bearing is housed in the crank. This is how you get one Rod head of small dimensions, and even ball bearings for the pin can be accommodated in the crank, protected and sealed there without requiring additional space will.

Auf der Zeichnung ist eine Ausführungsform eines Sägegatters in Abb. i dargestellt. Abb. a und 3 zeigen eine Kurbel im Schnitt und in Ansicht.The drawing shows an embodiment of a saw frame in Fig. i shown. Fig. A and 3 show a crank in section and in view.

Die Kurbelscheibe i hat ein Loch a, in das ein Kugellager 3 eingesetzt ist, in dem der Kurbelzapfen q. .ruht. Der Zapfen ist im Auge 5 der Schubstange befestigt. Das Lager ist auf der Rückseite durch den Boden 7 und vorn durch den Deckel 8 verschlossen, der einen Dichtungsring g trägt, und dessen Ansatz io das Kugellager festklemmt. Der Schubstangenkopf kann sehr klein sein, da er nur als Ring den eingesetzten Zapfen festzuhalten hat. Der Zapfen kann aber auch mit der Schubstange aus einem Stück bestehen.The crank disk i has a hole a into which a ball bearing 3 is inserted is in which the crank pin q. .rest. The pin is in the eye 5 of the push rod attached. The bearing is on the back through the bottom 7 and at the front through the Cover 8 closed, which carries a sealing ring g, and its approach io that Ball bearing stuck. The push rod head can be very small because it is only used as a Ring has to hold the inserted pin. The pin can also with the Push rod consist of one piece.
