Description

Schmiervorrichtung für stehende Wellen. Die Erfindung betrifft eine Schmiervorrichtung für stehende Wellen, insbesondere für die Kurbelwellen von Plansichtern und ähnlichen Apparaten, bei der das Öl durch eine in einen Ölsumpf tauchende Schraubennutpumpe von in bezug auf die Welle wesentlich größerem Durchmesser als diese gefördert wird. Sie besteht darin, daß die nicht bereits am unteren Ende des Pumpenkörpermantels beginnende Schraubennut ihre Ölzufuhr von innen her durch einen oder mehrere Kanäle in der Pumpenkörperwand erhält.Standing wave lubricator. The invention relates to a lubricating device for standing waves, in particular for the crankshafts of plan sifters and similar apparatus, in which the oil is conveyed by a screw-groove pump which is immersed in an oil sump and has a substantially larger diameter than the shaft. It consists in the fact that the screw groove that does not begin at the lower end of the pump body jacket receives its oil supply from the inside through one or more channels in the pump body wall.

Eine Ausführungsform der Erfindung ist in der Zeichnung dargestellt: Auf einen Hohlständer a, der Platz bietet zur Unterbringung der Antriebsscheibe der Welle f und in seinem Oberteil als Ölbehälter u ausgebildet ist, ist mittels der Schrauben w der Halslagerkörper b aufgesetzt, der zugleich in seinem Unterteil auch Pumpenkörper ist. Das Halslager dient als Führung für die Nabe g des Schwungrades, das das Kurbellager umschließt.An embodiment of the invention is shown in the drawing: On a hollow stand a, which offers space to accommodate the drive pulley the shaft f and is designed in its upper part as an oil tank u is by means of of the screws w of the neck bearing body b placed on it, at the same time in its lower part is also the pump body. The neck bearing serves as a guide for the hub g of the flywheel, that encloses the crank bearing.

Auf der in die Schwungradnabe g eingeschraubten Welle f ist ein umlaufender Pumpenkolben m aufgekeilt. Dieser trägt auf seiner äußeren Mantelfläche eine erst etwas oberhalb des unteren Endes des Mantels beginnende Schraubennut n und taucht mit seinem Unterteil in den Ölbehälter u. Bei der Drehung der Welle f fördert die Schraubennut Öl aus dem Behälter u nach dem Druckraum t oberhalb des Pumpenkolbens. Von da aus nimmt das Öl seinen Weg durch einen Kanal k zu einem um die Nabe g herumführenden Ringkanal o. Aus diesem tritt es durch die Bohrung p in das Innere der Schwungradnabe, steigt durch das Rohr r und übergießt das Lager. Der Eintrittswiderstand in die umlaufenden Kanäle p, der sich aus Kontraktion, Wirkung der Fliehkraft und statischem Öldruck zusammensetzt, wird durch den von der Pumpe erzeugten Überdruck leicht überwunden.A rotating shaft f is screwed into the flywheel hub g Pump piston m wedged. This carries a first on its outer surface The screw groove n starts slightly above the lower end of the jacket and plunges with its lower part in the oil tank and when rotating the shaft f promotes the Screw groove oil from the container u to the pressure chamber t above the pump piston. From there the oil takes its way through a channel k to a channel around the hub g Annular channel o. From this it emerges through the bore p into the interior of the flywheel hub, rises through the pipe r and pours over the bearing. The entry resistance into the circumferential channels p, consisting of contraction, effect of centrifugal force and static Composed of oil pressure, is easily overcome by the overpressure generated by the pump.

Aus dem Lager fließt das Ö1 durch die Kanäle L zurück in den Behälter u.The oil flows from the store through the channels L back into the container u.

Zur Speisung der Schraubennut n mit Öl sind von der Innenseite des Pumpenkolbens m aus Löcher v gebohrt, so daß das Öl der Nut infolge der Wirkung der Fliehkraft bereits mit einem bestimmten Druck zugeführt wird. Dadurch wird die Förderung und Leistung der Pumpe in bezug auf Menge und Druck vorteilhaft beeinflußt.To feed the screw groove n with oil, from the inside of the Pump piston m drilled out of holes v, so that the oil of the groove as a result of the action the centrifugal force is already supplied with a certain pressure. This will make the Delivery and performance of the pump in terms of quantity and pressure is favorably influenced.
