Abstract

Die Zahnradmaschine (Pumpe oder Motor) nach Figur 1 weist zwei im Außeneingriff kämmende Zahnräder (14, 15) auf, die in einer Gehäuseausnehmung (13) mit radialem Spiel angeordnet sind. Das Gehäusemittelteil (10) wird vor der endgültigen Montage der Maschine durch ein Federele­ ment (34) derart verschoben, daß die niederdruckseitigen Dichtbereiche (B, C) an die Stirnseiten der Zahnräder zum Anliegen kommen. Dazu ist ein radiales Spiel (b) zwischen den Wellenzapfen der Zahnräder und den sie aufnehmenden Gehäusebohrungen (21 bis 24) vorgesehen. Vor dem Beginn des Gehäuseeinlaufs wird die Maschine fest verschraubt. Dann wird von der Hochdruckseite (38) her Druckmittel zugeführt, und die Zahnräder werden in Rotation versetzt. Durch die hydraulische Kraft von der Hochdruckseite her dringen sie etwas in die niederdruckseitigen Dichtbereiche (B, C) ein. Dies wird als Gehäuseeinlauf bezeichnet, der nach einiger Zeit beendet wird, und eine gute Dichtheit von der Nieder- zur Hochdruckseite entlang des Außenumfangs der Zahnräder gewährleistet. The gear machine (pump or motor) according to FIG. 1 has two meshing gears (14, 15) on in a housing recess (13) with radial Game are arranged. The middle part of the housing (10) is in front the final assembly of the machine by a Federele ment (34) moved so that the low-pressure side Sealing areas (B, C) on the end faces of the gear wheels Concerns come. There is a radial play (b) between the shaft journal of the gears and the ones receiving them Housing holes (21 to 24) provided. Before the start the machine is screwed into the housing inlet. Then there is pressure medium from the high pressure side (38) fed, and the gears are set in rotation. Due to the hydraulic power from the high pressure side they penetrate somewhat into the sealing areas on the low pressure side (B, C) a. This is referred to as the housing inlet, which follows some time is finished, and a good tightness of the Low to high pressure side along the outer circumference of the Gears guaranteed.
