Abstract
Description
Schmiervorrichtung für einen Motorverdichter einer hermetisch gekapselten Kleinkältemaschine Die vorliegende Erfindung bezieht sich auf eine Schmiervorrichtung für einen Motorverdichter einer hermetisch gekapselten Kleinkältemaschine mit lotrechter Welle, in deren unteres Ende ein in einen Schmierölsumpf eintauchender Ansaugstutzen eingesteckt ist. Lubricating device for a motor compressor of a hermetically sealed Small refrigeration machine The present invention relates to a lubricating device for a motor compressor of a hermetically sealed small refrigeration machine with a vertical Shaft, in the lower end of which there is an intake port dipping into a lubricating oil sump is plugged in.
Es ist bereits bekannt, bei Ölpumpen für Kleinkältemaschinen mit Flügelrädern zu arbeiten, um eine Schwerkrafttrennung von Öl und Kältemittel zu erzielen, so daß eine Ausscheidung des Kältemitteldampfes aus dem Öl erzielt wird. Derartige Anordnungen erfordern erhebliche Kosten wegen des Aufwandes an zusätzlichen Elementen.It is already known in oil pumps for small refrigeration machines with impellers to work to achieve a gravity separation of oil and refrigerant, so that a separation of the refrigerant vapor from the oil is achieved. Such Arrangements require considerable costs because of the expense of additional elements.
In der Praxis findet deshalb ein Rohrstutzen in Form eines Fliehkraftkonus Anwendung, der im Betrieb das Schmieröl aus dem Olsumpf in eine Bohrung der lotrechten Welle der Kleinkältemaschine fördert.In practice there is therefore a pipe socket in the form of a centrifugal cone Application, which in operation the lubricating oil from the oil sump into a hole in the vertical Wave of the small refrigerator promotes.
Die vorliegende Erfindung sieht eine Verbesserung hinsichtlich der Schmierölförderung vor.The present invention provides an improvement in that Lubricating oil delivery before.
Erfindungsgemäß sind die freien Enden des in die Welle eingesetzten Ansaugstutzens als nach innen abgewinkelte Treibflächen gestaltet.According to the invention, the free ends are inserted into the shaft Intake nozzle designed as an inwardly angled propulsion surfaces.
Für die Ölförderung entfällt dadurch die Anwendung von Flügelrädern, die als selbständiges Teil zusätzlich gefertigt und in den Ansaugstutzen eingesetzt werden müssen.This eliminates the need for impellers for oil production, which are also manufactured as a separate part and inserted into the intake manifold Need to become.
Die Treibflächen des Ansaugstutzens werden je nach den zu stellenden Anforderungen zur Querschnittsebene geneigt ausgebildet.The motive surfaces of the intake manifold are depending on the to be placed Requirements inclined to the cross-sectional plane.
Dabei hat es sich als vorteilhaft erwiesen, die Treibflächen aus Zylindersegmenten zu bilden, deren seitliche Einschnittskanten unterschiedliche axiale Einschnittslängen aufweisen.It has proven to be advantageous to make the drive surfaces from cylinder segments to form, the lateral incision edges of which have different axial incision lengths exhibit.
Es besteht aber auch die Möglichkeit, die Treibflächen aus dem Boden eines hülsenartigen Stutzens herauszuarbeiten.But there is also the option of removing the drift surfaces from the ground to work out a sleeve-like nozzle.
Die Erfindung wird im folgenden anhand der Abbildungen an einem Ausführungsbeispiel erläutert: Fig. 1 zeigt schematisch einen Motorverdichter in einer hermetisch gekapselten Kleinkältemaschine.The invention is illustrated below using an exemplary embodiment explained: Fig. 1 shows schematically a motor compressor in a hermetically encapsulated Small refrigeration machine.
Fig. 2 zeigt einen Ausschnitt der lotrechten Welle mit dem eingesetzten Stutzen.Fig. 2 shows a section of the vertical shaft with the inserted Support.
Wie in Fig. 2 deutlich dargestellt, sind aus dem in die Welle 2 eingesetzten Ansaugstutzen 1 an seinem freien Ende Treibflächen 3 und 4 gestaltet.As clearly shown in FIG. 2, from the inserted into the shaft 2 are Intake connector 1 designed at its free end driving surfaces 3 and 4.
Diese Treibflächen werden zweckmäßig dadurch hergestellt, daß in einen Rohrstutzen axial verlaufende Einschnitte 5 und 6 für eine Treibfläche vorgesehen werden und danach die Treibflächen nach innen abgewinkelt werden.These driving surfaces are expediently produced in that in a Pipe socket axially extending incisions 5 and 6 are provided for a driving surface and then the drive surfaces are angled inward.
Je nach den zu stellenden Anforderungen werden die Treibflächen zur Querschnittsebene geneigt ausgebildet, was dadurch geschieht, daß die Einschnitte 5 und 6 unterschiedlich lang gehalten werden.Depending on the requirements to be set, the driving areas are used Cross-sectional plane formed inclined, which happens because the incisions 5 and 6 are held for different lengths of time.
Für die Praxis haben sich zwei Treibflächen als hinreichend erwiesen, es kann jedoch auch eine andere Anzahl von Treibflächen am Ansaugstutzen ausgebildet werden.In practice, two driving surfaces have proven to be sufficient, however, a different number of driving surfaces can also be formed on the intake manifold will.
