Description
Schubkurbelgetriebe._ Das Getriebe hat den Zweck, die Kolben d von zwei einander gegenüber angeordneten Pumpen o. dgl. zu bewegen. Es besteht aus der gekröpften Kurbelwelle a, einer Kulisse b, durch welche die Welle hindurchgesteckt ist, und zwei Ringen c, die auf der Kröpfung der Welle sitzen. Die Ringe laufen auf Kugeln. Die Kulisse wird durch die beiden Kolben d, mit denen sie fest verbunden ist, senkrecht zur Welle geführt. Zum Bewegen der Kulisse würde zwar schon ein Ring genügen, dieser müßte aber in der Kulisse einen kleinen Spielraum haben, .da er sich sonst nicht drehen könnte. Infolge dieses Spielraumes entstehen bei jedem Hubwechsel Stöße, die den Verschleiß der ganzen Maschine sehr beschleunigen und außerdem Geräusch verursachen, so daß ein solches Getriebe für höhere Umdrehungszahlen nicht verwendbar ist. Um das zu vermeiden, werden zwei Ringe nebeneinander angeordnet, von denen einer rechts und der andere links gegen .dieKulisse drückt, während auf der Rückseite beide frei laufen, weil die Kulisse hier ausgespart ist. Die Kulisse ist außerdem so geteilt, daß beide Hälften derselben durch Schrauben f und g gegen die Ringe gedrückt werden können. Unter die Schrauben können auch noch Federn h und i gelegt wenden, welche .die Ku_ lisse selbsttätig nachspannen, wenn sich die Laufbahn abnutzt.Slider crank mechanism._ The purpose of the gear mechanism is to move the pistons d of two pumps or the like arranged opposite one another. It consists of the cranked crankshaft a, a link b through which the shaft is inserted, and two rings c that sit on the crank of the shaft. The rings run on balls. The link is guided perpendicular to the shaft by the two pistons d with which it is firmly connected. A ring would be sufficient to move the backdrop, but it would have to have a little leeway in the backdrop, since otherwise it would not be able to turn. As a result of this margin, shocks occur with each stroke change, which greatly accelerate the wear and tear of the entire machine and also cause noise, so that such a gear cannot be used for higher speeds. To avoid this, two rings are arranged side by side, one of which presses against the backdrop on the right and the other on the left, while both of them run freely on the back because the backdrop is cut out here. The backdrop is also divided so that both halves of the same can be pressed against the rings by screws f and g. Springs h and i can also be placed underneath the screws, which automatically retension the joints when the raceway wears out.
Damit sich die Kulisse nicht verdrehen kann, und um den durch die rollende Reibung hervorgerufenen Druck senkrecht zur Bewegungsrichtung der Kolben aufzunehmen, wird die Kulisse auf einem Stab k, der parallel zur Bewegungsrichtung befestigt ist, geführt und der am einfachsten durch eine der durchbohrten Schrauben g gelegt wird, so daß diese Schraube einen langen Schlitten bildet.So that the backdrop cannot twist, and around the through the rolling friction caused pressure perpendicular to the direction of movement of the pistons record, the backdrop is on a rod k, which is parallel to the direction of movement is attached, guided and the easiest by one of the cannulated screws g is placed so that this screw forms a long slide.
