Abstract

In a star-shaped supporting frame for a horizontally mounted laundry drum, one of the arms (4) of the supporting frame serves as a fastening bearing for the drum drive motor (10). For this, an oscillating arm (8) is connected to the motor bearing plate (9) located on the drive side, is mounted in an oscillatory manner on the arm of the supporting frame and is fastened via a screw fastening (11) to the motor bearing plate located on the drive side, in an arcuate long hole (7) on the arm of the supporting frame. To make it easier to mount a drive motor in the way described, it is proposed that the motor bearing plate with its screw fastening should engage from one side of the arm of the supporting frame and the oscillating arm engage from the other side. <IMAGE>

Description

Die Erfindung geht aus von einer Trommelwaschmaschine mit einer in einem sternförmigen Traggestell um eine horizontale Achse drehbar gelagerten Wäschetrommel, die über ein Getriebe von einem an einem Arm des Traggestells befestigten Motor antreibbar ist, der über einen mit dem antriebsseitigen Motor-Lagerschild verbundenen Schwingarm an einem Schwinglagerauge des Traggestell-Arms in Grenzen schwingbeweglich gelagert und über eine Schraubbefestigung am antriebsseitigen Motor-Lagerschild in einem bogenförmigen Langloch am Traggestell-Arm befestigt ist.The invention relates to a drum washing machine with a washing drum rotatably mounted about a horizontal axis in a star-shaped support frame, which can be driven via a gear by a motor attached to an arm of the support frame, which is connected to a swing arm connected to the drive-side motor bearing plate Swinging bearing eye of the support frame arm is mounted so that it can oscillate within limits and is fastened to the support frame arm in a curved elongated hole by means of a screw fastening on the drive-side motor end shield.

Eine solche Trommelwaschmaschine ist aus der DE-OS 31 32 211 bekannt. Gegenüber einer Befestigung des Antriebsmotors über am Laugenbehälter einer Waschmaschine angeschweißte Winkelbleche hat diese Lösung Vorteile im Hinblich auf die Übertragung und Ausbreitung von Geräuschen, die der Antriebsmotor notwendigerweise verursacht. Außerdem ist diese Lösung gegenüber anderen Befestigungsarten mit mehreren Hilfsbauteilen rationeller. Diese Befestigungslösung stellt jedoch hohe Anforderungen an die für die Befestigung des Antriebsmotors zu verwendenden Schrauben Da der Motor zum schwingenden Aggregat einer Trommelwaschmaschine gehört und eine verhältmäßig hohe Masse hat, belasten die Beschleunigungs-Wechselkräfte die Schraubenköpfe in erheblichem Maße. Gleichartig hohe Belastungen treten auch bei Transport-Stößen auf, die in Richtung der Trommelachse der Waschmaschine wirken. Quer zur Trommelachse wirkende Stöße belasten die Schrauben durch Scherkräfte.Such a drum washing machine is known from DE-OS 31 32 211. Compared to fastening the drive motor via angle plates welded to the tub of a washing machine, this solution has advantages in terms of the transmission and propagation of noises which the drive motor necessarily causes. In addition, this solution is more efficient compared to other types of fastening with several auxiliary components. However, this fastening solution places high demands on the screws to be used for fastening the drive motor. Since the motor belongs to the vibrating unit of a drum washing machine and has a relatively high mass, the alternating acceleration forces put a considerable strain on the screw heads. Equally high loads also occur during transport impacts that act in the direction of the drum axis of the washing machine. Shocks acting transversely to the drum axis load the screws.

Der Erfindung liegt die Aufgabe zugrunde, den Befestigungsbereich bei der bekannten Trommelwaschmaschine so zu gestalten, daß die vorgenannten Belastungen nicht die Schraubenköpfe, sondern die Gußteile (Traggestell-Arm und Motor-Lagerschild) betreffen.The invention has for its object to design the mounting area in the known drum washing machine so that the aforementioned loads do not affect the screw heads, but the cast parts (support arm and motor end shield).

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Motor-Lagerschild mit seiner Schraubbefestigung von der einen Seite des Traggestell-Arms her und der Schwingarm von der anderen Seite her angreift. Hierdurch werden die Belastungskräfte beim Schleudern und beim Transport wenigstens zum Teil von den genannten Gußteilen aufgefangen und entlasten die Schraubenköpfe in erheblichem Maße.According to the invention, this object is achieved in that the motor end shield engages with its screw fastening from one side of the support frame arm and the swing arm from the other side. As a result, the loading forces during centrifuging and during transport are at least partially absorbed by the castings mentioned and relieve the screw heads to a considerable extent.

Hierzu ist es von besonderem Vorteil, daß entweder der Befestigungsbereich des Traggestell-Arms zwischen dem Schwinglagerauge und dem Langloch gekröpft ist oder daß der Schwingarm zwischen der Schraubbefestigung und dem Schwinglager gekröpft ist. Beide Merkmale können auch kombiniert angewendet werden; in jedem Fall ergibt sich hierdurch die gewünschte Abstützung der Trag-Elemente (Arm des Traggestells, Motor-Lagerschild, Schwingarm) unmittelbar und ohne Beanspruchung der Befestigungsschrauben.For this purpose, it is particularly advantageous that either the fastening area of the support frame arm between the pivot bearing eye and the elongated hole is cranked or that the rocker arm between the screw fastening and the pivot bearing is cranked. Both features can also be used in combination; in any case, this results in the desired support of the support elements (arm of the support frame, motor end shield, swing arm) directly and without stressing the fastening screws.

Wenn gemäß einer weiteren vorteilhaften Ausbildungsform das Schwinglager aus einer in das Lagerauge eingesetzten Buchse und einem am Schwingarm angebrachten Zapfen besteht, ergibt sich eine besondere Montagevereinfachung dadurch, daß der Motor mit seinem Schwingarm-Zapfen in das Schwinglager eingehängt werden kann und bei der weiteren Montage nicht mehr festgehalten werden muß.If, according to a further advantageous embodiment, the oscillating bearing consists of a bush inserted into the bearing eye and a pin attached to the oscillating arm, a particular simplification of assembly results from the fact that the motor with its oscillating arm pin can be hooked into the oscillating bearing and not during further assembly must be held more.

Eine besonders rationelle Darstellung dieser Lösung ergibt sich für einen Zapfen, der integraler Bestandteil des Schwingarmes ist.A particularly rational representation of this solution results for a pin that is an integral part of the swing arm.

In einer anderen vorteilhaften Weiterbildung besteht der Lagerzapfen aus einer Schraube, die den Schwingarm und den Traggestell-Arm durchdringt. Sie kann mit einer auf den durchgesteckten Gewindezapfen aufgeschraubten Mutter zusammen die sichere Montagebefestigung des Motors gewährleisten Dies ist insbesondere dann von Bedeutung, wenn aus irgendwelchen Gründen der Befestigungs-Sicherheit des Antriebsmotors durch eine einzige Schraube allein - nämlich der Schraubbefestigung am Motor-Lagerschild - nicht getraut werden kann.In another advantageous development, the bearing journal consists of a screw which penetrates the swing arm and the support arm. Together with a nut screwed onto the inserted threaded pin, it can ensure the secure mounting of the motor.This is particularly important if, for any reason, the fastening of the drive motor cannot be done by a single screw alone - namely the screw mounting on the motor end shield can be.

Im Falle der Befestigung des Antriebsmotors mittels zweier Schrauben, wie vorstehend beschrieben, ist eine Weiterbildung der Erfindung besonders vorteilhaft, bei der der Traggestell-Arm unterhalb seines Langlochs einen Führungsfinger aufweist, der in Montagelage des Motors das antriebsseitige Motor-Lagerschild fern von der Schraubbefestigung abstützt. Dadurch ergibt sich bei der Montage des an den Traggestell-Arm angesetzten Antriebsmotor dessen automatische Abstützung auf einem stabilen Kräfte-Dreieck gebildet, durch die Auflagefläche im Bereich des Langlochs und die Auflagefläche zwischen dem Führungsfinger und der die Antriebswelle des Motors umfassenden Stirnfläche des Motor-Lagerschilds.In the case of fastening the drive motor by means of two screws, as described above, a further development of the invention is particularly advantageous in which the support frame arm has a guide finger below its elongated hole, which supports the drive-side motor end shield in the mounted position of the motor, far from the screw fastening . This results in the assembly of the drive motor attached to the support arm, the automatic support of which is formed on a stable triangle of forces, through the contact surface in the area of the elongated hole and the contact surface between the guide finger and the end face of the motor end shield which comprises the drive shaft of the motor .

Der Laugenbehälter 1 einer Waschmaschine ist gewöhnlicherweise in einem sternförmigen Traggestell 2 befestigt, in dessen Nabe 3 in hier nicht näher dargestellter Weise der Lagerzapfen einer Wäschetrommel drehbar gelagert ist. Gemäß dem einleitend beschriebenen Stand der Technik ist an einem der abwärts gerichteten Arme des Traggestells 2, nämlich am Arm 4, eine fußartige Verlängerung 5 angebracht, welche die äußere Kontur des Laugenbehälters 1 überragt. Die fußartige Verlängerung 5 weist zwei Befestigungspunkte auf, ein Schwinglagerauge 6 und ein bogenförmiges Langloch 7. In das Schwinglagerauge 6 ist der Zapfen eines Schwingarmes 8 eingehängt, der fester Bestandteil des antriebsseitigen Lagerschilds 9 des Antriebsmotors 10 ist. Im Lagerschild 9 befindet sich eine Befestigungsbohrung 11 mit Gewinde, in die eine das Langloch 7 durchdringende Schraube (nicht dargestellt) eindrehbar ist. Mittels des Langlochs 7 läßt sich der Motor 10 um das Schwinglagerauge 6 schwenken, so daß ein Riemen (nicht dargestellt), der das Antriebsritzel 12 des Motors 10 umschlingt, gespannt werden kann.The tub 1 of a washing machine is usually fastened in a star-shaped support frame 2, in the hub 3 of which the bearing journal of a laundry drum is rotatably mounted in a manner not shown here. According to the prior art described in the introduction, a foot-like extension 5 is attached to one of the downward-pointing arms of the support frame 2, namely on the arm 4, which extends beyond the outer contour of the tub 1. The foot-like extension 5 has two fastening points, a pivot bearing eye 6 and an arcuate elongated hole 7. The pivot of a pivot arm 8 is suspended in the pivot bearing eye 6 and is a fixed component of the drive-side end plate 9 of the drive motor 10. In the end shield 9 there is a threaded mounting hole 11 into which a screw (not shown) penetrating the elongated hole 7 can be screwed. By means of the elongated hole 7, the motor 10 can be pivoted about the pivot bearing eye 6, so that a belt (not shown) which wraps around the drive pinion 12 of the motor 10 can be tensioned.

Entsprechend der Erfindung liegt der Motor-Lagerschild 9 im Bereich des das Langloch 7 tragenden Endes der fußartigen Verlängerung 5 von hinten her am Traggestell-Arm 4 an, während der Schwingarm 8 des Lagerschilds 9 um die fußartige Verlängerung 5 herumgreift und von der vorderen Seite des Traggestell-Arms 4 her angreift. Dadurch bildet der Motor-Lagerschild 9 mit seinem Schwingarm 8 gewissermaßen eine die fußartige Verlängerung 5 umgreifende Spange.According to the invention, the motor end shield 9 rests in the region of the end of the foot-like extension 5 carrying the slot 7 from behind on the support frame arm 4, while the swing arm 8 of the end shield 9 grips around the foot-like extension 5 and from the front side of the Support frame arms 4 attacks. As a result, the motor end shield 9 forms, with its swing arm 8, a clasp, as it were, around the foot-like extension 5.

Diese räumlichen Verhältnisse sind durch den in Fig. 2 dargestellten Schnitt besser verdeutlicht. Darin ist der Schwingarm 8 einstückig mit einem Lagerzapfen 13 verbunden ,der von der Rückseite des Laugenbehälters her nach vorn gerichtet ist und in das Lagerauge 6 eingreift. Zur besseren Dämpfung von Geräuschübertragungen ist das Lagerauge 6 außerdem mit einer Gummi-Metall-Buchse 14 bewehrt, deren innenliegende Metallbuchse mit dem Zapfen 13 eine Gleitpassung hat. Anstelle des fest angegossenen Zapfens 13 kann der Schwingarm 8 an dieser Stelle eine eingesetzte Schraube mit einem gewindelosen Gleitschaft haben, die von der vorderen Seite des Traggestell-Arms 4 her mit einer Mutter gesichert werden kann. Entsprechend ist zur Befestigung des das Langloch 7 tragenden Endes der fußartigen Verlängerung 5 im Schraubgewinde 11 des Motor-Lagerschilds 9 ebenfalls eine Schraube vorgesehen.These spatial relationships are better illustrated by the section shown in FIG. 2. In it, the swing arm 8 is integrally connected to a bearing pin 13 which is directed forward from the rear of the tub and engages in the bearing eye 6. For better damping of noise transmissions, the bearing eye 6 is also reinforced with a rubber-metal bushing 14, the inner metal bushing of which has a sliding fit with the pin 13. Instead of the firmly cast-on pin 13, the swing arm 8 can have an inserted screw with a threadless sliding shaft at this point, which can be secured from the front side of the support arm 4 with a nut. Correspondingly, a screw is also provided for fastening the end of the foot-like extension 5 carrying the elongated hole 7 in the screw thread 11 of the motor end shield 9.

Bei dem in Fig. 3 dargestellten Ausführungsbeispiel trägt das das Langloch 7 enthalt ende Ende der fußartigen Verlängerung 5 noch einen Führungsfinger 15. Dieser Führungsfinger 15 reicht bis vor den ringförmigen Bereich des Lagerschilds, durch den die Motorwelle 16 mit ihrem vorn angebrachten Ritzel 12 nach außen ragt.In the embodiment shown in FIG. 3, the end of the foot-like extension 5 containing the elongated hole 7 also carries a guide finger 15. This guide finger 15 extends up to the annular area of the end shield through which the motor shaft 16 with its pinion 12 attached to the front extends outwards protrudes.

Der in Fig. 4 dargestellte Schnitt entlang der Schwing-Bogenlinie IV-IV ist um 90° gegenüber Fig. 3 gedreht, so daß der obere Teil aus Fig. 3 in Fig. 4 rechts liegt. Zur besseren Verdeutlichung der räumlichen Verhältnisse des Führungsfingers 15 und der Motorwelle 16 ist die vor der Schnittlinie liegende Motorwelle 16 mit Ritzel 12 in Fig. 4 ebenfalls eingezeichnet. Hieraus ist erkennbar, daß der in der gezeichneten Lage von vorn auf die fußartige Verlängerung 5 aufgestellte Motor mit seinem Motor-Lagerschild 9 auf den vorderen Flächen 17 im Bereich des Langloches 7 und 18 im Bereich des Führungsfingers 15 aufliegt und damit eine stabile Lage einnehmen kann, ohne weiter gehalten zu werden, bis die nicht dargestellte Schraube durch das Langloch 7 hindurch in das Gewinde 11 eingedreht ist. Der Abstand der die Motorwelle 16 umschlingenden Ringfläche des Lagerschilds 9 zur vorderen Fläche 18 des Führungsfingers 15 soll verdeutlichen, daß diese Ringfläche zwar möglichst eng an der vorderen Fläche 18 des Führungsfingers 15 anliegen soll, jedoch auf keinen Fall einen größeren Abstand zu der vorderen Auflagefläche des Stutzens für das Gewinde 11 haben darf, als der Abstand zwischen den Flächen 17 und 18 an der fußförmigen Verlängerung 5 beträgt.The section shown in FIG. 4 along the oscillating curved line IV-IV is rotated by 90 ° with respect to FIG. 3, so that the upper part of FIG. 3 is on the right in FIG. 4. For better clarification of the spatial relationships of the guide finger 15 and the motor shaft 16, the motor shaft 16 with pinion 12 lying in front of the cutting line is also shown in FIG. 4. From this it can be seen that in the position shown from the front on the foot-like extension 5 motor with its motor bearing plate 9 rests on the front surfaces 17 in the region of the elongated hole 7 and 18 in the region of the guide finger 15 and can therefore assume a stable position without being held until the screw, not shown, is screwed through the elongated hole 7 into the thread 11. The distance of the ring surface of the end shield 9 which wraps around the motor shaft 16 to the front surface 18 of the guide finger 15 is intended to clarify that this ring surface should lie as closely as possible to the front surface 18 of the guide finger 15, but in no case a greater distance from the front contact surface of the Stubs for the thread 11 may have, as the distance between the surfaces 17 and 18 on the foot-shaped extension 5.

Bei den dargestellten Ausführungsbeispielen sind sowohl die fußartige Verlängerung 5 wie auch der Schwingarm 8 so gekröpft, daß die Anlageflächen am Schwinglagerauge und an der Schraubbefestigung jeweils gewechselt sind. Diese räumliche Anordnung ist jedoch auch dadurch zu erzielen, daß entweder nur die fußartige Verlängerung 5 oder nur der Schwingarm 8 entsprechend gekröpft ist. Der Führungsfinger 15 kann ferner eine andere Form aufweisen und/oder an einer anderen Stelle des Motor-Lagerschilds 9 angreifen.In the illustrated embodiments, both the foot-like extension 5 and the swing arm 8 are cranked so that the contact surfaces on the swing bearing eye and on the screw fastening are changed. However, this spatial arrangement can also be achieved in that either only the foot-like extension 5 or only the swing arm 8 is cranked accordingly. The guide finger 15 can also have a different shape and / or engage at a different location on the motor end shield 9.

Die erfindungsgemäße Ausformung der Motorbefestigung verhindert übermäßige Belastungen der Schraubenköpfe bei Stößen auf das schwingende Aggregat. Stöße von vorn werden teilweise von der Zapfenbefestigung des Schwingarms 8 aufgefangen, während Stöße von hinten auf das schwingende Aggregat durch die Anlageflächen zwischen dem Motor-Lagerschild 9 und der fußartigen Verlängerung 5 aufgefangen werden. Die in Fig. 2 dargestellte Gummi-Metall-Buchse dämpft Übertragungen von vom Antriebsmotor 10 erzeugten Schwingungen auf das Aggregat. Durch den gemäß Fig. 2 ausgebildeten Schwingarmzapfen ist noch eine zusätzliche Montagevereinfachung gegeben, weil lediglich eine Schraube zum Befestigen des Motors angezogen werden muß.The shape of the motor mounting according to the invention prevents excessive loads on the screw heads in the event of impacts on the vibrating unit. Shocks from the front are partially absorbed by the pin attachment of the swing arm 8, while shocks from behind on the vibrating unit are absorbed by the contact surfaces between the motor end shield 9 and the foot-like extension 5. The rubber-metal bushing shown in FIG. 2 dampens transmissions of vibrations generated by the drive motor 10 to the unit. An additional simplification of the assembly is given by the swing arm pivot designed according to FIG. 2, because only one screw has to be tightened for fastening the motor.
