Description
Elastische Aufhängung eines mit einer Zentrifugentrommel gekuppelten Elektromotors Die Erfindung betrifft eine elastische Aufhängung eines mit einer Zentrifugentrommel gekuppelten Elektromotors mit zwischen Motorgehäuse und Zentrifugengehäuse radial liegenden, elastischen, schwingungsdämpfenden Tragelementen, die an im Bodenteil des Zentrifugengehäuses verankerten, im wesentlichen senkrecht verlaufenden Stäben angeordnet sind.Elastic suspension of one coupled to a centrifuge drum Electric motor The invention relates to an elastic suspension with a Centrifuge drum coupled electric motor with between motor housing and centrifuge housing radially lying, elastic, vibration-damping support elements that are attached to the bottom part the centrifuge housing anchored, essentially perpendicular rods are arranged.
Eine derartige elastische Aufhängung ist in Anspruch 1 des Hauptpatentes dadurch gekennzeichnet, daß die oberen Stabenden in einen gegenüber dem Zentrifugengehäuse durch eine Gummidichtung abgestützten Zwischenboden befestigt sind.Such an elastic suspension is in claim 1 of the main patent characterized in that the upper rod ends in an opposite the centrifuge housing are attached to the intermediate floor supported by a rubber seal.
Zwischen den Stäben und dem Motorgehäuse sind als schwingungsdämpfende Tragelemente breite Gummibänder radial angeordnet, die den Motor mit der Trommel halten. Die Querschnitte der Gummibänder erstrecken sich im wesentlichen in horizontaler Richtung, wodurch die Gummibänder starken Zugbeanspruchungen unterliegen.Between the rods and the motor housing are as vibration-damping Supporting elements wide rubber bands arranged radially that connect the motor to the drum keep. The cross-sections of the rubber bands extend essentially in the horizontal direction Direction, whereby the rubber bands are subject to strong tensile stresses.
Die hohen Betriebsdrehzahlen einer Wäschezentrifuge können bei ungleichmäßiger Belastung der Schleudertrommel erhebliche Massenkräfte verursachen, die auf die Dämpfungselemente übertragen werden und zu einer sehr hohen Zugbeanspruchung des Gummis führen, welche bei diesem Material vermieden werden soll.The high operating speeds of a laundry centrifuge can with uneven Load on the centrifugal drum cause considerable inertia forces on the Damping elements are transferred and a very high tensile stress of the Lead rubbers, which should be avoided with this material.
Bei elastischen Motoraufhängungen anderer Art ist es bereits bekannt, einen Motor über senkrecht angeordnete, mit Löchern bzw. Durchbrüchen versehene Schwingmetallpuffer mit Stützen zu verbinden. Eine andere elastische Motoraufhängung sieht hochkant angeordnete Z-förmige Gummikörper vor, die mit ihren oberen Armen auf Stützzapfen aufgesteckt werden, wobei der Motor von den unteren Armen getragen wird.In the case of elastic engine mountings of other types, it is already known a motor over vertically arranged, provided with holes or breakthroughs To connect anti-vibration buffers with supports. Another elastic engine mount provides upright Z-shaped rubber bodies with their upper arms be placed on support pins, with the motor carried by the lower arms will.
In weiterer Ausbildung der im Hauptpatent gekennzeichneten elastischen Motoraufhängung wird vorgeschlagen, daß die band- oder scheibenförmigen elastischen, schwingungsdämpfenden Tragelemente hochkant angeordnet sind.In further training the elastic ones identified in the main patent Engine suspension is proposed that the band or disk-shaped elastic, Vibration-damping support elements are arranged on edge.
Damit wird erreicht, daß sowohl das Gewicht des Schleuderaggregats als auch die Massenkräfte überwiegen als Schubkraft auf das Material der flachen Dämpfungsgummis übertragen werden, wodurch einerseits eine bessere Ausnutzung der Federungseigenschaft des Materials und andererseits eine materialgerechte gleichmäßigere und wesentlich geringere Beanspruchung sichergestellt sind, ohne daß es hierzu aufwendiger Einrichtungen -wie etwa vulkanisierter Schwingmetallpuffer, - bedarf. Auch ist durch die neue Anordnung der flachen Dämpfungselemente eine bessere Führung des Schleuderaggregats gewähr-. leistet. Ferner ist es mit der neuen Anordnung der flachen scheibenförmigen oder bandförmigen Dämpfungselemente in Weiterbildung der Erfindung möglich, die Einspannung so vorzunehmen, daß an jedem Ende des Dämpfungselements je eine zu seiner Flachseite parallel verlaufende Bohrung vorgesehen ist und das Dämpfungselement mit dieser Bohrung je auf einen an der gehäuseseitigen Säule und einem am Motorgehäuse festen Bolzen gesteckt ist, woraus sich eine besonders leichte Auswechselbarkeit und eine gleichmäßige, die Beanspruchung im Dämpfungselement gut verteilende Einspannung ergibt.This ensures that both the weight of the centrifugal unit as well as the mass forces predominate as a thrust force on the material of the flat Damping rubbers are transferred, whereby on the one hand a better utilization of the Resilience of the material and, on the other hand, a more uniform material-specific and significantly less stress are ensured without it being more expensive to do so Facilities - such as vulcanized anti-vibration buffers - are required. Also is through the new arrangement of the flat damping elements better guidance of the centrifugal unit guarantee. perform. Furthermore, it is with the new arrangement of the flat disk-shaped or band-shaped damping elements in a development of the invention possible that Make clamping so that at each end of the damping element one to his Flat side parallel bore is provided and the damping element with this hole each on one on the housing-side column and one on the motor housing fixed bolt is inserted, which makes it particularly easy to replace and even restraint that distributes the stress well in the damping element results.
Die Erfindung sei an Hand der in der Zeichnung schematisch dargestellten Ausführungsbeispiele veranschaulicht. Es zeigt Fig. 1 eine elastische Motoraufhängung nach der Erfindung in Gesamtansicht, teilweise axial geschnitten, Fig. 2 die vergrößerte Darstellung einer Motoraufhängung ähnlich Fig. 1, teilweise geschnitten, Fig. 3 ein Dämpfungselement im Profil, Fig.4 eine andere Ausführungsform des Dämpfungselements. Über dem senkrecht angeordneten Motor 10 (Fig. 1) ist auf dessen Wellenstumpf 11 die Schleudertrommel 12 tragend befestigt, und das so gebildete Schleuderaggregat ist durch im Motorraum 13 des Gehäuses 14 radial eingespannte flache, hochkant stehende Band-oder scheibenförmige Gummidämpfer 3 (Fig. 3, 4) getragen. Die Gummidämpfer sind einerseits über an den Lagerschilden des Motors 10 feste Bolzen 4 und andererseits über an einer am Gehäuse festen Stützsäule angebrachte Bolzen 2 geschoben. Die Säule 5 ist, wie aus Fig.1 und 2 ersichtlich, zwischen dem Sockel 1 und dem Boden 8 des Schleuderraumes 16 der Wäschezentrifuge eingespannt. Der Boden 8 ist mit einem Dichtungsring in oder über einer Sicke 9 eingepaßt.The invention is based on the schematically illustrated in the drawing Exemplary embodiments illustrated. 1 shows an elastic engine mount according to the invention in an overall view, partially in axial section, Fig. 2 the enlarged Representation of an engine mount similar to FIG. 1, partially in section, FIG. 3 a damping element in profile, FIG. 4 another embodiment of the damping element. Above the vertically arranged motor 10 (Fig. 1) is on its stub shaft 11 the Centrifugal drum 12 attached to supporting, and the centrifugal unit thus formed is by in the engine compartment 13 of the housing 14 radially clamped flat, upright standing Belt or disk-shaped rubber damper 3 (Fig. 3, 4) carried. The rubber damper are on the one hand on the end shields of the motor 10 fixed bolts 4 and on the other hand pushed over a bolt 2 attached to a support column fixed to the housing. The pillar 5 is, as can be seen from Figures 1 and 2, between the base 1 and the bottom 8 of the Centrifugal chamber 16 clamped the laundry centrifuge. The bottom 8 is provided with a sealing ring fitted in or over a bead 9.
Bei scheibenförmiger Ausführung der Dämpfungselemente (Fig. 3) erhalten diese an beiden Enden eine Verdickung mit einer parallel zur Flachseite verlaufenden, den Bolzen 2, 4 entsprechenden Bohrung.With a disk-shaped design of the damping elements (Fig. 3) obtained these have a thickening at both ends with a parallel to the flat side, the corresponding hole for bolts 2, 4.
