Description
Die Erfindung betrifft eine Pumpe für ein Hochdruckreinigungsgerät mit einem Motor und einem Pumpenkopf, die gemeinsam in einem Gehäuse festgelegt sind.The invention relates to a pump for a high-pressure cleaning device with a motor and a pump head, which are fixed together in a housing.
Baueinheiten aus einem Motor und einer daran befestigten und von diesem angetriebenen Pumpe werden in Hochdruckreinigungsgeräten verwendet und dazu häufig in ein Gehäuse eingebaut, in welchem die Baueinheit im Abstand zur Gehäusewand gelagert werden muß. Diese Lagerung soll nach Möglichkeit so erfolgen, daß Schwingungen und Geräusche zwischen dem Gehäuse und der Baueinheit möglichst wenig übertragen werden. Es sind dazu komplizierte Aufhängevorrichtungen bekannt, beispielsweise die Baueinheit umgebende Gummimanschetten, mit deren Hilfe die Baueinheit in einem Gehäuse aufgehängt werden kann.Components from a motor and a pump attached to it and driven by it are used in high-pressure cleaning devices and for this purpose are often installed in a housing in which the component must be stored at a distance from the housing wall. This storage should, if possible, take place in such a way that vibrations and noises are transmitted as little as possible between the housing and the structural unit. For this purpose, complicated suspension devices are known, for example rubber sleeves surrounding the assembly, with the aid of which the assembly can be suspended in a housing.
Es ist Aufgabe der Erfindung, eine konstruktiv besonders einfache gedämpfte Lagerung einer derartigen Baueinheit in einem Gehäuse anzugeben, bei der auch die Montage gegenüber herkömmlichen Konstruktionen vereinfacht ist.It is an object of the invention to provide a structurally particularly simple damped mounting of such a structural unit in a housing, in which the assembly is also simplified compared to conventional designs.
Diese Aufgabe wird bei einer Pumpe der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß das Gehäuse aus zwei Halbschalen besteht, daß beide Halbschalen parallel zur Verbindungsrichtung beider Halbschalen verlaufende Vertiefungen aufweisen, in denen jeweils ein Lagerkörper aus einem gummielastischen Werkstoff angeordnet ist, der seinerseits zur jeweils anderen Halbschale hin offene und parallel zur Verbindungsrichtung der Halbschalen gerichtete Ausnehmungen aufweist, und daß die Baueinheit aus Motor und Pumpenkopf auf gegenüberliegenden Seiten parallel zueinander verlaufende, komplementär in die Ausnehmungen passende und mit diesen ausgerichtete Vorsprünge trägt.This object is achieved according to the invention in a pump of the type described at the outset in that the housing consists of two half-shells, that both half-shells have depressions running parallel to the connecting direction of the two half-shells, in each of which a bearing body made of a rubber-elastic material is arranged, which in turn is used for each other half-shell open and parallel to the connecting direction of the half-shells recesses, and that the assembly of motor and pump head on opposite sides parallel to each other, complementary in the recesses and aligned with these projections.
Eine solche Ausgestaltung ermöglicht eine sehr einfache schwingungsgedämpfte Lagerung der Baueinheit in einem Gehäuse. Es genügt nämlich, die Baueinheit in die untere Halbschale so einzusetzen, daß die an der Baueinheit an der Unterseite angeordneten Vorsprünge in die Ausnehmungen der Lagerkörper der unteren Halbschale eingreifen. Anschließend wird die zweite Halbschale von oben her, d.h. in Verbindungsrichtung, an die untere Halbschale herangeführt, und dabei greifen die Vorsprünge an der Oberseite der Baueinheit in die Ausnehmungen der Lagerkörper der oberen Halbschale ein. Sobald die beiden Halbschalen aneinanderliegen, werden sie in dieser Position fest miteinander verbunden, die Vorsprünge an der Baueinheit tauchen dabei vollständig in die entsprechenden Ausnehmungen der Lagerkörper an der Unterseite und an der Oberseite, also in den beiden Halbschalen, des Gehäuses ein, so daß die Baueinheit dadurch im Gehäuse einwandfrei festgelegt ist. Ein besonderes Werkzeug ist dazu nicht notwendig, auch der konstruktive Aufwand ist außerordentlich gering, da es genügt entsprechende Vorsprünge an der Baueinheit vorzusehen und entsprechende Vertiefungen mit gummielastischen Lagerkörpern an den beiden Halbschalen.Such an embodiment enables a very simple vibration-damped mounting of the structural unit in a housing. It is sufficient to insert the assembly into the lower half-shell in such a way that the projections arranged on the bottom of the assembly engage in the recesses in the bearing bodies of the lower half-shell. The second half-shell is then brought up to the lower half-shell from above, that is to say in the direction of connection, and the projections on the top of the structural unit engage in the recesses in the bearing bodies of the upper half-shell. As soon as the two half-shells lie against each other, they are firmly connected to each other in this position, the projections on the assembly are completely immersed in the corresponding recesses in the bearing bodies on the underside and on the top, i.e. in the two half-shells, of the housing, so that the The unit is thereby fixed in the housing. A special tool is not necessary for this, and the design effort is also extremely low, since corresponding projections are sufficient to be provided on the structural unit and corresponding recesses with rubber-elastic bearing bodies on the two half-shells.
Günstig ist es, wenn die Vertiefungen in den Halbschalen topfförmig ausgebildet sind.It is expedient for the depressions in the half-shells to be cup-shaped.
Bei einer bevorzugten Ausführungsform der Erfindung sind die Lagerkörper in die Vertiefungen eingesetzte Stopfen.In a preferred embodiment of the invention, the bearing bodies are plugs inserted into the depressions.
Zusätzlich können in der Wand der Lagerkörper deren Zusammendrückbarkeit erhöhende Ausnehmungen angeordnet sein. Dadurch lassen sich die Vorsprünge unter Umständen besser im Klemmsitz in die Lagerkörper einführen, außerdem können dadurch gegebenenfalls Toleranzen besser ausgeglichen werden. Trotzdem kann bei derartigen Lagerkörpern ein Material verwendet werden, daß selbst keine allzuhohe Zusammendrückbarkeit zeigt, so daß eine sehr stabile Lagerung gewährleistet ist.In addition, recesses which increase their compressibility can be arranged in the wall of the bearing body. As a result, the projections can be better inserted into the bearing bodies in a clamped fit, and tolerances can also be better compensated for as a result. Nevertheless, a material can be used in such bearing bodies that itself does not show too high compressibility, so that a very stable storage is guaranteed.
Die Vorsprünge können bevorzugt an das Motorgehäuse angeformte Zapfen sein.The projections can preferably be pegs molded onto the motor housing.
Bei einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß das Gehäuse einen kreisförmigen Querschnitt aufweist, daß der Motor und die Pumpe im wesentlichen koaxial in diesem kreiszylindrischen Gehäuse angeordnet sind und daß die Vorsprünge etwa tangential am ebenfalls kreiszylindrisch ausgebildeten Motorgehäuse angeordnet sind. Eine solche Anordnung nützt den Raum optimal aus, der bei kreiszylindrischer Ausgestaltung des Gehäuses an der Außenseite verbleibt, so daß die Bauhöhe des Gehäuses insgesamt dadurch nicht oder nur unwesentlich erhöht wird.In a preferred embodiment of the invention it is provided that the housing has a circular cross-section, that the motor and the pump are arranged essentially coaxially in this circular-cylindrical housing and that the projections are arranged approximately tangentially on the likewise circular-cylindrical motor housing. Such an arrangement makes optimum use of the space that remains on the outside in the case of a circular cylindrical configuration of the housing, so that the overall height of the housing is not increased or is increased only insignificantly as a result.
Besonders vorteilhaft ist es, wenn die beiden Halbschalen im wesentlichen spiegelbildlich ausgebildet sind.It when the two half-shells are essentially mirror images is particularly advantageous.
Im Zwischenraum zwischen Motorgehäuse und dem äußeren Gehäuse können am Motorgehäuse angeformte Kühlrippen angeordnet sein.Molded cooling fins can be arranged in the space between the motor housing and the outer housing.
Es ist vorteilhaft, wenn die Vorsprünge an einem schwingungsarmen Teil des Motorgehäuses angeordnet sind, beispielsweise dem Teil, der den Stator des Elektromotors umgibt. In diesem Bereich zeigt das Motorgehäuse die geringsten Schwingungen, und dadurch ist auch die Übertragung der Schwingungen vom Motorgehäuse auf das umgebende Gehäuse auf ein Minimum reduziert.It is advantageous if the projections are arranged on a low-vibration part of the motor housing, for example the part that surrounds the stator of the electric motor. The motor housing shows the lowest vibrations in this area, and the transmission of the vibrations from the motor housing to the surrounding housing is also reduced to a minimum.
Die nachfolgende Beschreibung einer bevorzugten Ausführungsform der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Die Zeichnung zeigt eine Querschnittansicht eines in einem zweischaligen Gehäuse gelagerten Motors.The following description of a preferred embodiment of the invention serves in conjunction with the drawing for a more detailed explanation. The drawing shows a cross-sectional view of an engine mounted in a double-shell housing.
Der in der Zeichnung nur sehr schematisch wiedergegebene Motor 1 ist in einem kreiszylindrischen Gehäuse 2 untergebracht, an welches an der Außenseite abstehende Kühlrippen 3 angeformt sind. An der Unterseite und an der Oberseite sind senkrecht nach oben und senkrecht nach unten abstehende Zapfen 4 an das Gehäuse 2 angeformt, sie sind in dem dargestellten Ausführungsbeispiel miteinander ausgerichtet und verlaufen gegenüber einer senkrechten Tangente an das Gehäuse 2 geringfügig nach innen versetzt. Vorzugsweise sind die Zapfen 4 in dem Bereich an das Gehäuse 2 angeformt, der den Stator des Elektromotors umgibt, da dieser Teil des Gehäuses besonders schwingungsarm ist.The motor 1, which is shown only very schematically in the drawing, is accommodated in a circular
Das Motorgehäuse 2 wird umgeben von einem äußeren Gehäuse 5, welches ebenfalls im wesentlichen kreiszylindrisch ausgebildet ist und welches aus zwei im wesentlichen gleich ausgebildeten Halbschalen 6, 7 geformt wird.The
Jede der beiden Halbschalen weist eine in Richtung der Verbindungsrichtung der beiden Halbschalen, d.h. senkrecht zur Trennebene der beiden Halbschalen verlaufende, topfförmige Vertiefung 8 auf, in die ein gummielastischer Stopfen 9 eingesteckt ist. Dieser Stopfen 9 weist eine zentrale, zur Innenseite hin offene und parallel zur Achse der Vertiefung 8 verlaufende Ausnehmung 10 auf, deren Durchmesser im wesentlichen dem Durchmesser des Zapfens 4 entspricht. In der Wand des gummielastischen Stopfes 9 sind weitere Ausnehmungen 11 vorgesehen, beispielsweise in Form von Ringnuten oder Durchgangsbohrungen, die die Zusammendrückbarkeit des gummielastischen Materials in diesem Bereich erhöhen.Each of the two half-shells has one in the direction of the connection direction of the two half-shells, i.e. Pot-
Zur Positionierung des Motors 1 in dem Gehäuse 5 wird der Motor 1 von oben her in die untere Halbschale 6 eingelegt, und zwar derart, daß der Zapfen 4 an der Unterseite des Gehäuses 2 in die Ausnehmung 10 des Stopfens 9 der unteren Halbschale 6 eingreift. Anschließend wird von oben her die zweite Halbschale 7 aufgesetzt, und beim Aufsetzen wird der Stopfen 9 der oberen Halbschale 7 so über den an der Oberseite des Gehäuses 2 angeordneten Zapfens 4 geschoben, daß dieser Zapfen 4 in die Ausnehmung 10 des Stopfens 9 der oberen Halbschale 7 eintritt. Nach der vollständigen Annäherung der beiden Halbschalen 6 und 7 werden diese miteinander verbunden, beispielsweise durch Verschraubung. Die an der Unterseite und an der Oberseite des Gehäuses 2 abstehenden Zapfen 4 tauchen dann vollständig in die Ausnehmungen 10 der Stopfen 9 ein, und dadurch wird der Motor 1 im Inneren des Gehäuses 5 exakt fixiert, und zwar über eine Brücke aus gummielastischem Werkstoff, so daß die Übertragung von Geräuschen und Schwingungen weitgehend gedämpft wird.To position the motor 1 in the
Zur Verbindung des Motors mit dem äußeren Gehäuse 5 ist keinerlei Werkzeug notwendig, es genügt, die beiden Halbschalen 6 und 7 in der beschriebenen Weise in Verbindungsrichtung aneinander anzunähern und sie dann bei vollständiger Anlage miteinander zu verbinden.No tools are required to connect the motor to the
