Description

Die Erfindung betrifft einen Schieberantrieb für gekapselte Dampfmaschinen.The invention relates to a slide drive for encapsulated steam engines.

Bei gekapselten Dampfmaschinen, die meist mit Umlaufschmierung ausgerüstet sind, pflegt die Schieberstange durch das Kurbelgehäuse hindurchgeführt und gegen dieses abgedichtet zu werden. Wenn diese Abdichtung undicht wird, gelangt Dampf bzw. Kondenswasser in das Kurbelgehäuse und vermischt sich mit dem Umlaufschmieröl für die Lager. Die Lagerschmierung wird hierdurch beeinträchtigt, und die Lager nutzen sich vorzeitig ab. Insbesondere bei kleinen schnellaufenden Dampfmaschinen tritt diese Schwierigkeit leicht auf.With encapsulated steam engines, which are usually equipped with circulating lubrication are, maintains the slide rod passed through the crankcase and against this to be sealed. If this seal starts to leak, steam will escape or condensation water in the crankcase and mixes with the circulating lubricating oil for the camp. This affects the lubrication of the bearings and the bearings wear out prematurely. Especially with small, high-speed steam engines this difficulty occurs easily.

Gemäß der Erfindung greift die Schieberstange nicht auf der Kurbelwellenseite, sondern an der entgegengesetzten Seite des Schiebers an. Dies ist in der Abbildung am Beispiel einer kreuzkopflosen Maschine dargestellt. Am Schieber h ist die Schieberstange i befestigt, die über ein Querhaupt k, eine Führungsstange 1, welche in der Büchse m geführt wird, sowie die Exzenterstange n durch den Exzenter o bewegt wird. Wenn die Abdichtung der Schieberstange i im Zylinderdeckel b undicht wird, tritt Dampf oder Kondenswasser nicht in das Kurbelgehäuse, sondern ins Freie.According to the invention, the slide rod does not engage on the crankshaft side, but on the opposite side of the slide. This is shown in the illustration using the example of a machine without a crosshead. The slide rod i is attached to the slide h and is moved by the eccentric o via a cross head k, a guide rod 1 which is guided in the bushing m, and the eccentric rod n. If the seal of the slide rod i in the cylinder cover b leaks, steam or condensation water does not enter the crankcase, but rather outside.

Zum Druckausgleich ist unterhalb des Schiebers lt der Kolben p vorgesehen, der in die Schieberbohrung dicht eingepaßt ist. Leckwasser kann durch eine Bohrung q ins Freie treten. Es ist hier innere Einströmung angenommen; der Dampf tritt durch die Bohrung r ein und verläßt die Maschine bei s. Es kann aber auch äußere Einströmung gewählt werden; dann müßte der Dampf bei s einströmen und bei r ausströmen. Auf den Kolben p könnte dann wegen des geringen Druckes des Abdampfes meist verzichtet werden, und die Bohrung q würde dann wegfallen. Um dann ebenfalls einen Druckausgleich gegen den Zudampfdruck zu erreichen, müßte die Schieberstange i an der Stelle, wo sie durch den Zylinderdeckel b hindurchgeführt wird, denselben Durchmesser erhalten wie der Schieber h. Bei doppelt wirkenden Maschinen ist, da dort dieser Druckausgleich nicht nötig ist, der Schieber wie üblich auszubilden.For pressure equalization, the piston p, which is tightly fitted into the slide bore, is provided below the slide lt. Leakage water can escape through a hole q. Internal influx is assumed here; the steam enters through the bore r and leaves the machine at s. However, external inflow can also be selected; then the steam would have to flow in at s and flow out at r . The piston p could then usually be dispensed with because of the low pressure of the exhaust steam, and the bore q would then be omitted. In order to achieve pressure equalization against the steam addition pressure, the slide rod i would have to have the same diameter as the slide h at the point where it is passed through the cylinder cover b. With double-acting machines, since this pressure equalization is not necessary there, the slide should be designed as usual.
