Description

Die Erfindung betrifft eine Vorrichtung zwischen einer Pumpe und einem Elektromotor mit einer die Pumpenwelle und die Motorenwelle verbindenden Welle, wobei die Welle von einem Gestell insbesondere einem Käfig bzw. einer Laterne umgeben ist, an dem zu einer Seite der Motor und auf der gegenüberliegenden Seite die Pumpe befestigt sind, wobei das Gestell außenseitig Stützen insbesondere in Form von Stegen aufweist, die im Wesentlichen parallel zur Welle verlaufen, und wobei das Gestell außenseitig von mindestens einer Verkleidung überdeckt ist.The invention relates to a device between a pump and an electric motor with a shaft connecting the pump shaft and the motor shaft, wherein the shaft is surrounded by a frame, in particular a cage or a lantern on which to one side of the motor and on the opposite side Pump are mounted, wherein the frame on the outside supports, in particular in the form of webs, which extend substantially parallel to the shaft, and wherein the frame is covered on the outside by at least one panel.

Es ist bekannt, an einer Pumpe einen Elektromotor über ein Gestell zu befestigen, das auch "Laterne" genannt wird und auf dessen einen Seite die Pumpe und auf der gegenüberliegenden Seite der Elektromotor befestigt ist. Durch das Gestell verläuft eine Welle, die die Motorenwelle mit der Pumpenwelle verbindet und die eine Kupplung aufweist. Hierbei ist es auch bekannt, das Gestell (Laterne) außenseitig mit einer Verkleidung zu versehen, so dass die Welle und insbesondere die Kupplung gegen eine Berührung von außen geschützt sind. Die Verkleidung kann an dem Gestell angeschraubt sein, wobei sich als nachteilig erwiesen hat, dass nach dem Abschrauben der Verkleidung die Schrauben verloren werden können.It is known to attach to a pump, an electric motor via a frame, which is also called "lantern" and on one side of the pump and on the opposite side of the electric motor is attached. Through the frame extends a shaft which connects the motor shaft with the pump shaft and having a coupling. Here it is also known to provide the frame (lantern) on the outside with a panel, so that the shaft and in particular the coupling are protected against contact from the outside. The panel may be screwed to the frame, which has proven to be disadvantageous that after unscrewing the panel, the screws can be lost.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art so zu verbessern, dass nach dem Abschrauben der Verkleidung die Schrauben weiterhin zur Verfügung stehen, so dass die Verkleidung als Schutzvorrichtung jederzeit wieder befestigbar ist, und damit eine hohe Sicherheit gegeben ist.The object of the invention is to improve a device of the type mentioned so that after unscrewing the panel, the screws continue to be available, so that the panel as a protective device at any time can be fastened again, and thus a high level of security is given.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Verkleidung an den Stützen/Stegen durch Schrauben lösbar befestigt ist, die im aufgeschraubten Zustand unlösbar an der Stütze/dem Steg gehalten sind.This object is achieved in that the panel is releasably secured to the supports / webs by screws, which are held in the unscrewed state inextricably on the support / the web.

Nach Entfernen der Verkleidung von dem Gestell (Laterne) bleiben die Schrauben weiterhin unverlierbar mit der Pumpe bzw. dem Gestell verbunden, so dass ein einfacher und sicherer Wiedereinsatz der Verkleidung und damit der Schutzvorrichtung gegeben ist. Auch bei nicht völlig festgezogenen Schrauben verbleibt die Verkleidung/Schutzvorrichtung in ihrer Position.After removing the panel from the frame (lantern), the screws remain captive connected to the pump or the frame, so that a simple and safe reuse of the panel and thus the protection is given. Even with not completely tightened screws the panel / protection device remains in position.

Vorzugsweise wird hierzu vorgeschlagen, dass die Schrauben an ihrem inneren Ende eine Erweiterung aufweisen, um unverlierbar zu sein. Besonders vorteilhaft ist es hierbei, wenn die Schrauben im Innengewinde eines buchsenförmigen Einsatzes eingeschraubt sind, die in einer Bohrung der Stütze/des Steges einliegt.Preferably, it is proposed for this purpose that the screws have an extension at their inner end in order to be captive. It is particularly advantageous here if the screws are screwed into the internal thread of a bush-shaped insert, which rests in a bore of the support / the web.

Vorzugsweise wird vorgeschlagen, dass die Schraube mit einem inneren Bereich über den Einsatz hinaus nach innen vorsteht. Hierbei kann der innere Bereich der Schraube kein Gewinde aufweisen und einen Außendurchmesser besitzen, der gleich oder geringer ist, als der Innendurchmesser des Gewindes des Einsatzes.It is preferably proposed that the screw projects inwardly beyond the insert with an inner region. Here, the inner portion of the screw may have no thread and have an outer diameter which is equal to or less than the inner diameter of the thread of the insert.

Hierbei kann die Verkleidung aus Blech oder Kunststoff bestehen. Besonders vorteilhaft ist es, wenn die Stützen/die Stege aus Kunststoff bestehen, so dass das Kunststoffmaterial aufgrund seiner Breite einen genügend großen Halt für den Einsatz bieten kann.Here, the panel can be made of sheet metal or plastic. It is particularly advantageous if the supports / the webs are made of plastic, so that the plastic material can provide a sufficiently large grip for use due to its width.

Besonders vorteilhaft ist es, wenn nach dem Lösen der Schrauben die Verkleidung abnehmbar ist, ohne die Schrauben herausziehen zu müssen. Dies wird dadurch erreicht, dass die Schraube in einer schlitzförmigen Öffnung der Verkleidung einliegt, wobei die Öffnung einen ersten schmalen Bereich aufweist, mit einer Breite kleiner als der Durchmesser des Schraubenkopfes, und einen zweiten breiteren insbesondere kreisförmigen Bereich aufweist, mit einer Breite insbesondere einem Durchmesser gleich oder größer als der Durchmesser des Schraubenkopfes.It is particularly advantageous if, after loosening the screws, the covering can be removed without having to remove the screws. This is achieved in that the screw rests in a slot-shaped opening of the panel, wherein the opening has a first narrow area, having a width smaller than the diameter of the screw head, and a second wider, in particular circular region having a width, in particular a diameter equal to or greater than the diameter of the screw head.

Damit die Schraubenköpfe über die Verkleidung nicht hinausstehen, wird vorgeschlagen, dass der erste schmale Bereich der schlitzförmigen Öffnung der Verkleidung eine Senke bildet, in der der Schraubenkopf versenkt einliegt. Vorzugsweise wird vorgeschlagen, dass die Welle innerhalb des Gestells eine Kupplung aufweist.So that the screw heads do not protrude beyond the cladding, it is proposed that the first narrow region of the slit-shaped opening of the cladding forms a depression in which the screw head engages in a countersunk manner. It is preferably proposed that the shaft has a coupling within the frame.

Zum Antrieb einer Pumpe ist an dieser ein Elektromotor über ein käfigförmiges Zwischengestell 1 befestigt, an dessen eine Seite die Pumpe und an dessen gegenüberliegenden Seite der Motor befestigt insbesondere angeflanscht ist. Ein solches Zwischengestell wird auch "Laterne" genannt und weist an einem Ende einen Befestigungsring (insbesondere mit Flansch) für die Pumpe und am gegenüberliegenden Ende einen Befestigungsring (insbesondere mit Flansch) für den Motor auf. Beide Ringe sind durch zueinander parallele Stützen bzw. Stege 2 insbesondere aus Kunststoff miteinander verbunden und im Innenraum des Gestells 1 verläuft eine Welle 3 insbesondere mit dazwischengeschalteter Kupplung 4. Die Welle 3 verbindet die Pumpenwelle mit der Motorenwelle.To drive a pump, an electric motor is fastened to it via a cage-shaped intermediate frame 1, on one side of which the pump is fastened and on the opposite side of which the motor is fastened in particular. Such an intermediate frame is also called "lantern" and has at one end a fastening ring (in particular with a flange) for the pump and at the opposite end a fastening ring (in particular with a flange) for the engine. Both rings are interconnected by mutually parallel supports or webs 2 in particular made of plastic and in the interior of the frame 1 extends a shaft 3 in particular with interposed clutch 4. The shaft 3 connects the pump shaft with the motor shaft.

Das Gestell 1 ist außenseitig von einer flächigen Verkleidung 5 aus Blech oder Kunststoff rundum vollständig bedeckt, die an den Stützen/Stegen 2 angeschraubt und damit lösbar ist. An den Schraubstellen weisen die Stützen/Stege 2 Bohrungen 6 auf, in denen jeweils ein buchsenförmiger Einsatz 7 befestigt einliegt, vorzugsweise eingespritzt oder eingegossen oder mit selbstschneidendem Gewinde eingeschraubt. Der Einsatz 7 weist ein Innengewinde auf, in das die Schraube 8 mit ihrem Außengewinde 9 eingeschraubt ist.The frame 1 is completely covered on the outside by a flat panel 5 made of sheet metal or plastic, which is screwed to the supports / webs 2 and thus solvable. At the screw points, the supports / webs 2 holes 6, in each of which a bush-shaped insert 7 rests fastened, preferably injected or cast or screwed with self-tapping thread. The insert 7 has an internal thread into which the screw 8 is screwed with its external thread 9.

Die Schraube 8 besitzt an ihrem vorderen Ende einen Kopf 10 und im hinteren Bereich einen zylindrischen Bereich 11 ohne Gewinde und mit kleinerem Durchmesser als der des Außengewindes 9. Ferner ist am inneren Ende der Schraube 8 eine ringförmige Platte 12 als Erweiterung bzw. Stoppring befestigt, die einen größeren Außendurchmesser aufweist als der Innendurchmesser der Bohrung 6. Durch diese Konstruktion kann die Schraube 8 losgeschraubt werden, ohne im gelösten Zustand abzufallen. Hierbei weist der Bereich 11 eine axiale Länge auf, die vorzugsweise größer ist als die axiale Länge der Bohrung 6.The screw 8 has at its front end a head 10 and in the rear region a cylindrical portion 11 without thread and with a smaller diameter than that of the external thread 9. Further, at the inner end of the screw 8, an annular plate 12 is attached as an extension or stop ring, which has a larger outer diameter than the inner diameter of the bore 6. By this construction, the screw 8 can be unscrewed without falling off in the dissolved state. In this case, the region 11 has an axial length which is preferably greater than the axial length of the bore 6.

Die Schraube 8 durchquert in der Verkleidung 5 eine Öffnung 13, die schlitzförmig ausgebildet ist. Die Schraube liegt in der schlitzförmigen Öffnung 13 der Verkleidung 5 ein, wobei die Öffnung einen ersten schmalen Bereich 13a aufweist, mit einer Breite kleiner als der Durchmesser des Schraubenkopfes 10 und einen zweiten breiteren insbesondere kreisförmigen Bereich 13b, mit einer Breite insbesondere einem Durchmesser gleich oder größer als der Durchmesser des Schraubenkopfes, um eine Renkverbindung zu bilden. Der erste schmale Bereich 13a der schlitzförmigen Öffnung der Verkleidung bildet eine Senke 14, in der der Schraubenkopf 10 versenkt einliegt.The screw 8 traverses in the panel 5 an opening 13 which is slit-shaped. The screw is in the slot-shaped opening 13 of the panel 5, wherein the opening has a first narrow portion 13a, with a width smaller than the diameter of the screw head 10 and a second wider particular circular portion 13b, with a width in particular a diameter equal or greater than the diameter of the screw head to form a recessed joint. The first narrow region 13a of the slot-shaped opening of the lining forms a depression 14, in which the screw head 10 engages sunk.

Im aufgeschraubten Zustand der Schraube 8 braucht die Verkleidung 5 mit ihrer Öffnung 13 nur so weit verschoben werden, dass der zweite Bereich 13b den Kopf 10 erreicht hat. Dann kann der Öffnungsbereich 13b über den Kopf 10 geschoben werden, um die Verkleidung 5 zu entfernen. Ein Wiederbefestigen der Verkleidung erfolgt in umgekehrter Reihenfolge.In the screwed-on state of the screw 8, the panel 5 with its opening 13 only needs to be displaced so far that the second area 13b has reached the head 10. Then, the opening portion 13b may be slid over the head 10 to remove the trim 5. Reinstalling the panel is done in reverse order.
