Description

Es' sind _Pumpen zur Schmierung von Lagerstellen bekannt, die einen senkrecht zur Umlaufachse arbeitenden Pumpenstempel besitzen. Dieser Pumpenstempel wird aus einem Stück hergestellt. Er besteht aus zwei verschiedene Durchmesser besitzenden Zylindern, die in entsprechende Bohrungen passen. Bei der Herstellung dieser Bohrungen läßt es sich nicht vermeiden, daß die beiden Bohrungsachsen etwas gegeneinander versetzt sind, so daß sich Schwierigkeiten beim Einschleifen. des Pumpenstempels ergeben und außerdem eine genaue Passung nicht erzielbar ist.There 'are _Pumps for the lubrication of bearings known that one Have pump rams working perpendicular to the axis of rotation. This pump stamp is made from one piece. It consists of two different diameters Cylinders that fit into corresponding holes. When making these holes it cannot be avoided that the two bore axes are somewhat opposed to one another are offset, so that there are difficulties in grinding. of the pump ram result and, moreover, an exact fit cannot be achieved.

Diesen Nachteil vermeidet der Gegenstand der Erfindung dadurch, daß der Pumpenstempel aus zwei Teilen zusammengesetzt ist die aneinander anliegen, ohne miteinander in fester Verbindung zu stehen. Ein Ausführungsbeispiel -ist in den Abb. i a bis i c dargestellt.The object of the invention avoids this disadvantage in that the pump ram is composed of two parts that rest against each other without to be in close contact with each other. One embodiment is shown in Fig.i a to i c shown.

Abb. i a zeigt einen Schnitt durch die Pumpe an der Stelle, an der der Pumpenstempel angeordnet ist, Abb. i b einen Schnitt in Richtung A-B und Abb. i c einen Schnitt in Richtung C-D der Abb. i a.Fig. I a shows a section through the pump at the point where the pump ram is arranged, Fig.i b a section in direction A-B and Fig. i c a section in the direction C-D of Fig. i a.

In dem Pumpengehäuse i läuft das den Pumpenstempel mitnehmende Teil 2 um. Das Gehäuse i ist -an ,der Stelle, an der der Pumpenstempel sitzt, exzentrisch ausgedreht, so daß beim Drehen des Teiles 2 der Pumpenstempel hin und her gehende Bewegungen ausführt. Das bei q. eintretende Schmieröl wird bei den Hinundherbewegungen des Pumpenstempels bei 5 aus dem Gehäuse herausgedrückt.The part which entrains the pump ram runs in the pump housing i 2 um. The housing i is eccentric at the point where the pump ram sits turned out, so that when turning part 2 of the pump ram going back and forth Movements. That at q. Incoming lubricating oil will occur during the floats of the pump plunger at 5 pushed out of the housing.

Erfindungsgemäß wird nun der Pumpenstempel aus zwei Teilen gebildet, von denen beispielsweise das Teil 6 den größeren und: das Teil 7 den kleineren Durchmesser hat. Sind jetzt die Achsen der beiden Bohrungen etwas gegeneinander versetzt, so kann der Pumpenstempel 6, 7 seine Bewegungen ausführen, ohne daß ein Anliegen auftritt.According to the invention, the pump ram is now formed from two parts, of which, for example, part 6 has the larger and part 7 has the smaller diameter. If the axes of the two bores are now somewhat offset from one another, the pump ram 6, 7 can carry out its movements without a concern.
