Abstract

Improvements in a compressor unit of the type which includes a radial piston compressor and a drive motor disposed in a housing about a stationary shaft are disclosed. The shaft is suspended from the housing by an elastic coupling to substantially suppress the transmission of vibrations and sound from the compressor unit to the housing. In a disclosed embodiment, the shaft is suspended by a rod-shaped elastic support member fastened to the housing and protruding into a cavity defined by a hollow portion of the shaft where the elastic member is connected to the shaft. According to one aspect of the invention, transmission of vibration and sound can be attenuated without the need to provide additional space by providing the unit's pressure outlet duct as the elastic support member.

Description

Die Erfindung betrifft ein Verdichter-Aggregat, bei dem in einem Aggregatgehäuse ein Radihlkolbenverdichter und dessen Antriebsmotor gemeinsam auf einer feststehenden, zumindest im Bereich ihres einen Endes hohl ausgebildetEIn Achse angeordnet sind, die am Aggregatgehäuse adfgehängt ist.The invention relates to a compressor unit, in which a rotary piston compressor and its drive motor are arranged together in a unit housing on a fixed axis which is hollow at least in the area of one end thereof and which is attached to the unit housing.

Ein solches Verdichter-Aggregat ist durch die DL-B 2710734 bekannt. Bei diesem Verdichter-Aggregat ist die feststehende Achse starr an dem Aggregatgehäuse aufgehängt. Dadurch werden Schwingungen und Schallwellen ungedämpft auf das Aggregatgehäuse übertragen.Such a compressor unit is known from DL-B 2710734. With this compressor unit, the fixed axle is rigidly suspended from the unit housing. As a result, vibrations and sound waves are transmitted to the unit housing without damping.

Durch die DE-A 1503408 ist ein aus einem Elektromotor und einem Kolbenverdichter bestehendes Verdichter-Aggregat bekannt, bei dem der Motor und der Verdichter auf einer feststehenden, hohl ausgebildeten Achse angeordnet sind. Zur Schwingungsdämpfung ist die Achse an beiden Enden über Federn an dem Aggregatgehäuse beweglich abgestützt.DE-A 1503408 discloses a compressor unit consisting of an electric motor and a piston compressor, in which the motor and the compressor are arranged on a fixed, hollow axis. To dampen vibrations, the axle is movably supported at both ends by springs on the unit housing.

Der Erfindung liegt die Aufgabe zugrunde, ein Verdichter-Aggregat der eingangs beschriebenen Art so auszubilden, daß durch eine bewegliche Aufhängung der feststehenden Achse die Übertragung von Schwingungen und Körperschall nach außen weitgehend unterbunden ist, wobei die konstruktive Ausführung der beweglichen Aufhängung raumsparend sein soll.The invention has for its object to provide a compressor unit of the type described in such a way that the transmission of vibrations and structure-borne noise to the outside is largely prevented by a movable suspension of the fixed axis, the design of the movable suspension should be space-saving.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß die Achse mittels eines in deren Hohlraum hineinragenden und mit seinem einen Ende im Hohlraum mit der Achse verbundenen und mit seinem anderen Ende am Aggregatgehäuse befestigten stangenförmigen, elastischen Traggliedes aufgehängt ist. Das elastische Tragglied ist so dimensioniert, daß es die beim Anfahren und Auslaufen des Verdichter-Aggregates auftretenden Reaktionsbeschleunigungsmomente sowie das Gewicht des Aggregates übertragen kann und im übrigen das Verdichter-Aggregat in horizontaler Richtung frei schwingen läßt.The object is achieved according to the invention in that the axis is suspended by means of a rod-shaped, elastic support member which projects into its cavity and has one end connected to the axis in the cavity and the other end attached to the unit housing. The elastic support member is dimensioned so that it can transmit the reaction acceleration moments occurring when starting and stopping the compressor unit and the weight of the unit and, moreover, allows the compressor unit to vibrate freely in the horizontal direction.

Nach einer weiteren Ausgestaltung der Erfindung kann bei einem Verdichter-Aggregat, bei dem die Achse am verdichterseitigen Ende hohl ausgebildet ist, als Tragglied vorteilhafterweise die Druckleitung des Radialkolbenverdichters vorgesehen werden. Diese Druckleitung wird dann in ihrer Länge und in ihrem Querschnitt so bemessen, daß sie die zum freien Schwingen notwendige Elastizität aufweist. Auf diese Weise wird ein gesondertes Tragglied eingespart.According to a further embodiment of the invention, the pressure line of the radial piston compressor can advantageously be provided as a supporting element in a compressor unit in which the axis is hollow at the end on the compressor side. This pressure line is then dimensioned in its length and cross-section so that it has the elasticity necessary for free swinging. In this way, a separate support member is saved.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels wird der Anmeldungsgegenstand nachfolgend näher beschrieben.The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing.

Das Verdichter-Aggregat besteht aus einem Radialkolbenverdichter 1 und einem Antriebsmotor 2. Der Radialkolbenverdichter 1 und der Antriebsmotor 2 sind auf einer gemeinsamen feststehenden Achse 3 angeordnet. Die feststehende Achse 3 ist an dem verdichterseitigen Ende 4 hohl ausgebildet. In dem Hohlraum 5 der feststehenden Achse 3 ist die von dem Radialkolbenverdichter nach außen führende Druckleitung 6 angeordnet. Mit ihrem einen Ende 7 ist die Druckleitung 6 in dem Hohlraum 5 mit der feststehenden Achse 3 verbunden. Mit ihrem anderen Ende 8 ist die Druckleitung 6 an einem auf das Aggregatgehäuse 9 aufgesetzten Verteilerkopf 10 befestigt. Die Befestigung an dem Verteilerkopf 10 ist mittels eines Preßkonus 11 durchgeführt. Über einen in der feststehenden Achse 3 ausgebildeten Kanal 12 ist die Druckleitung 6 mit dem Druckschlitz des Radialkolbenverdichters 1 verbunden.The compressor unit consists of a radial piston compressor 1 and a drive motor 2. The radial piston compressor 1 and the drive motor 2 are arranged on a common fixed axis 3. The fixed axis 3 is hollow at the end 4 on the compressor side. The pressure line 6 leading outward from the radial piston compressor is arranged in the cavity 5 of the fixed axis 3. With one end 7, the pressure line 6 is connected in the cavity 5 with the fixed axis 3. With its other end 8, the pressure line 6 is attached to a distributor head 10 placed on the unit housing 9. The attachment to the distributor head 10 is carried out by means of a press cone 11. The pressure line 6 is connected to the pressure slot of the radial piston compressor 1 via a channel 12 formed in the fixed axis 3.

Über dem Verteilerkopf 10 ist eine Kappe 13 auf das Aggregatgehäuse 9 aufgesetzt, die eine Druckkammer 14 bildet. In diese Druckkammer mündet das Druckrohr 6 mit seinem anderen Ende 8. Über einen an der Kappe 13 vorgesehenen Druckstutzen 15 kann das verdichtete Gas abgeführt werden. An dem Verteilerkopf 10 ist ferner ein Saugstutzen 16 angeformt, der durch die Wand der Kappe 13 nach außen geführt ist. Der Verteilerkopf 10 weist ferner auf der dem Aggregatgehäuse 9 zugewandten Seite eine von einem Ringflansch 17 umgebene Ansaugöffnung 18 auf. Die feststehende Achse endet an dieser Ansaugöffnung 18. Zwischen dem Ringflansch 17 und dem in diesen Ringflansch hineinragenden Ende 19 der feststehenden Achse 3 sind Dichtungen 20 eingefügt. Diese Dichtungen dichten die Ansaugöffnung 18 zwar gegenüber dem Innenraum des Aggregatgehäuses 9 ab, lassen aber dennoch eine Dreh- und Pendelbewegung der feststehenden Achse 3 zu. Über den Hohlraum 5, der mit dem Saugschlitz 21 des Radialkolbenverdichters 1 in Verbindung steht, erfolgt die Ansaugung des zu verdichtenden Gases.A cap 13, which forms a pressure chamber 14, is placed on the unit housing 9 above the distributor head 10. The other end of the pressure pipe 6 opens into this pressure chamber 8. The compressed gas can be discharged via a pressure connection 15 provided on the cap 13. On the distributor head 10, a suction nozzle 16 is also formed, which is guided through the wall of the cap 13 to the outside. The distributor head 10 also has a suction opening 18 surrounded by an annular flange 17 on the side facing the unit housing 9. The fixed axis ends at this suction opening 18. Seals 20 are inserted between the ring flange 17 and the end 19 of the fixed axis 3 protruding into this ring flange. Although these seals seal the suction opening 18 from the interior of the unit housing 9, they nevertheless allow the fixed axis 3 to rotate and oscillate. The gas to be compressed is sucked in via the cavity 5, which is connected to the suction slot 21 of the radial piston compressor 1.

Das Druckrohr 6 ist in seiner Länge und in seinem Querschnitt so bemessen, daß es infolge seiner Elastizität horizontale Schwingungen des Verdichter-Aggregates zuläßt. Infolge der Elastizität des Druckrohres 6 können sich diese Schwingungen nur in geringem Maße auf das Aggregatgehäuse 9 übertragen.The pressure tube 6 is dimensioned in its length and in its cross section so that it allows horizontal vibrations of the compressor unit due to its elasticity. As a result of the elasticity of the pressure tube 6, these vibrations can only be transmitted to the unit housing 9 to a small extent.

Ist bei einem Verdichter kein derartiges, zentrisch angeordnetes Druckrohr vorhanden, so muß an dessen Stelle ein gesondertes stangenförmiges Tragglied vorgesehen werden. Ein solches Tragglied kann dann rohrförmig, d. h. hohl oder auch voll ausgebildet sein.If such a centrally arranged pressure pipe is not available in a compressor, then a separate rod-shaped support member must be provided in its place. Such a support member can then be tubular, i.e. H. be hollow or fully formed.
