"Radialkolbenpumpe""Radial piston pump"
Die Erfindung betrifft eine Radialkolbenpumpe mit einer Exzenterwelle zum Antrieb der Kolben, bei der die Hubbewegung durch eine oder mehrere auf der Exzenterwelle gelagerte Gleithülsen auf die Kolben übertragen wird.The invention relates to a radial piston pump with an eccentric shaft for driving the piston, in which the stroke movement through one or more sliding sleeves mounted on the eccentric shaft on the pistons is transmitted.
Die Erfindung hat sich die Aufgabe gestellt, Kolbenpumpen der hier in Frage stehenden Art so zu verbessern, daß im Bereich der öleithülaenlagerung tine besonders gute Wärmeabfuhr erreicht wird. Zu dem oben genanntenThe invention has set itself the task of improving piston pumps of the type in question here in such a way that that in the area of oil shell storage tine is particularly good good heat dissipation is achieved. To the above

Zweok ist gemäß der Erfindung bei der neuen Radialkolbenpumpe vorgesehen, daß das angesaugte Fördermedium durch die teilweise axial durchbohrte Exzenterwelle und über die Schmierspalt« der Gleithülsenlager, die durch Badialbohrungen alt der Axialbohrung in der Exzenterwelle verbunden sind, den Pumpenzylindern zugeführt wird. Hierbei kann z.B. di· Saugleitung mit dem die saugseitige Stirnfläch· der Exzenterwelle umgebenden Kaum über einen radialen Kanal in Verbindung stehen, in den die Axialbohrung der Welle mündet.According to the invention, Zweok is in the new one Radial piston pump provided that the sucked-in pumped medium through the partially axially pierced Eccentric shaft and via the lubricating gap «of the sliding sleeve bearings, which are connected to the axial bore in the eccentric shaft by means of badial bores, is fed to the pump cylinders. Here, for example, the The suction line with the suction-side face of the eccentric shaft surrounding it hardly has a radial one Channel in connection into which the axial bore of the shaft opens.
Bei der erfindungsgemäßen Anordnung ergibt sieh der Vorteil, daß nunmehr das angesaugte Fördermedium, durch die Exzenterwelle hinduroh und an der Lagerung der Gleithülse vorbei dem Saugölringraum zugeführt wird. Hierdurch wird erreicht, daß der (Jleithülaenlagerung ständig frisches, kaltes Fördermedium zugeführt wird, so daß eine unzulässig hohe Erwärmung des Schmierfilms vermieden wird.In the arrangement according to the invention, see the result Advantage that now the sucked-in pumped medium, hinduroh by the eccentric shaft and on the storage of the Sliding sleeve is fed over to the suction oil annulus. This ensures that the (Jleithülaenlagerung fresh, cold pumping medium is constantly fed in, so that the lubricating film is heated to an inadmissibly high level is avoided.
In der Zeichnung ist ein AusfUhrungsbeispiel des Gegenstandes der Erfindung in einer Seitenansicht In einem axialen Schnitt in schematischer Darstellung gezeigt.The drawing shows an exemplary embodiment of the subject matter of the invention in a side view axial section shown in a schematic representation.
