Description
,Als Rückstellfeder wirkende Scheiben- oder Tellerfeder für die Ankerscheibe einer elektromagnetisch betätigten Kupplung oder Bremse Bei elektromagnetisch betätigten Kupplungen oder Bremsen ist es allgemein üblich, die zur Erzeugung des Kupplungsschlusses bzw. der Anpreßkraft axial bewegliche Ankerscheibe ineiner axialen Führungsverzahnung auf dem Kupplungskörper zu lagern. Diese Art der Lagerung hat den Nachteil, daß sich nicht nur die ineinandergreifenden Verzahnungen schnell ausschlagen, sondern daß auch infolge des für die axiale Beweglichkeit erforderlichen Zahnspiels die Ankerscheibe gegenüber der verzahnten Nabe, auf der sie sitzt, in Umfangsrichtung zunächst nur geringfügig beweglich ist. Das Maß dieser Beweglichkeit in Umfangsrichtung vergrößert sich jedoch mit zunehmender Abnutzung der Längsverzahnung, so daß dann beim Einrücken der Kupplung mit fortschreitender Abnutzung immer stärker werdende in Umfangsrichtung verlaufende Belastungsstöße auftreten, die schnell zur Zerstörung der Verzahnungen führen., A disc or disc spring acting as a return spring for the armature disc an electromagnetically operated clutch or brake with electromagnetically operated It is common practice to use clutches or brakes to generate the clutch engagement or the pressure force axially movable armature disk in an axial guide toothing to be stored on the coupling body. This type of storage has the disadvantage that not only do the interlocking teeth knock out quickly, but that also as a result of the backlash required for axial mobility Armature disk opposite the toothed hub on which it sits, in the circumferential direction is initially only slightly movable. The extent of this mobility in the circumferential direction increases with increasing wear of the longitudinal toothing, so that then increasing wear and tear as the clutch engages circumferential load shocks occur that can quickly lead to destruction of the gears.
-Ura diesem übelstand abzuhelfen, ist es bekannt, die Ankerscheibe mit lElfe einer Gummischeibe, die an ihrem äußeren Umfang mit der Ankerscheibe selbst und an ihrem inneren Umfang mit dem die Ankerscheibe tragenden Körper fest verbunden ist, so zu lagern, daß sie in Umfangsrichtung kein Spiel hat. Dem hierbei auftretenden Nachteil, daß die Gummischeibe ungeeignet ist, in Umfangsrichtung größere Drehmomente zu übertragen, hat man dadurch entgegenzuwirken versucht, daß man in die Gunimischeibe radial verlaufende Blattfedern einbettete, die die Stelfigkeit in der Umfangsrichtung sichern sollten.-Ura to remedy this problem, it is known to use the armature disk with one eleven of a rubber washer, which on its outer circumference with the armature disk itself and firmly connected at its inner circumference to the body carrying the armature disk is to be stored so that it has no play in the circumferential direction. The occurring here Disadvantage that the rubber washer is unsuitable for larger torques in the circumferential direction to transfer, one has tried to counteract this by entering the Gunimi disc embedding radially extending leaf springs, which the stelfigkeit in the circumferential direction should secure.
Ebenfalls bekannt sind axial federnde Scheiben, bei denen zur Verbesserung des axialen Federungsvermögens Ausstanzungen angebracht sind, die entweder den inneren oder den äußeren Umfang oder beide unterbrechen. Solche Stahlringscheiben sind jedoch für den hier vorliegenden Zweck unbrauchbar, da sie insbesondere keine Sicherheit für die Starrheit bei Belastun,gen in Umfangsrichtung, also für die Drehmomentübertragung bieten.Also known are axially resilient washers, in which to improve of the axial resilience punched out are attached, either the inner or interrupt the outer perimeter, or both. Such steel ring disks are, however useless for the purpose at hand here, in particular because they have no security for the rigidity with loads in the circumferential direction, i.e. for the torque transmission Offer.
Ferner sind Federscheiben bekannt, die Durchbrechungen aufweisen, die weder den äußeren noch den inneren Umfang dieser Ringscheibe unterbrechen.Furthermore, spring washers are known which have openings which interrupt neither the outer nor the inner circumference of this washer.
Diese Federscheiben, bei denen die Durchbrechungen kreisbogenförnug ausgebildet und in Umfangsrichtung sowie in radialer Richtung gegeneinander versetzt angeordnet sind, bieten zwar genügend Sicherheit für die Starrheit bei Belastungen in Umfangsrichtung, sie besitzen jedoch noch kein allzu befriedigendes axiales Federungsvermögen.These spring washers, in which the openings are circular arc-shaped formed and offset from one another in the circumferential direction and in the radial direction are arranged, offer sufficient security for the rigidity under loads in the circumferential direction, but they do not yet have an overly satisfactory axial resilience.
ErfIndungsgemäß wird nun vorgeschlagen, die Durchbrechungen U-förmig auszubilden und diese einander so zuzuordnen, daß abwechselnd die einander benachbarten Schenkel zweier radial innenliegender Durchbrechungen zwischen die Schenkel einer radial außenliegenden Durchbrechung greifen und umgekehrt.According to the invention, it is now proposed that the openings be U-shaped train and assign them to each other so that alternately the adjacent Legs of two radially inner openings between the legs of one grip radially outer opening and vice versa.
Die vorteilhaften Eigenschaften einer erfindungsgemäß ausgebildeten stählernen Scheiben- oder Tellerfeder ergeben sich aus folgender Betrachtung: Da die federnde Länge sich bei dieser Ausbildung aus der Länge des vom inneren Umfang ausgehenden Schenkels, der Länge des Schenkels zum Ende des vom äußeren Umfang ausgehenden Schenkels und der Länge dieses Schenkels zusammensetzt, beträgt die federnde Gesamtlänge ein Mehrfaches der Differenz zwischen dem Außen- und dem Innendurchmesser der Scheiben- oder Tellerfeder.The advantageous properties of a steel disc or plate spring designed according to the invention result from the following consideration: Since the resilient length in this design is the length of the leg extending from the inner circumference, the length of the leg to the end of the leg extending from the outer circumference and the length composing this leg , the total resilient length is a multiple of the difference between the outer and inner diameter of the disc or disc spring.
Das axiale Faderungsvermögen der Scheiben- oder Tellerfeder ist also durch Vergrößerung der federnden Länge wesentlich gesteigert. Außerdem bleibt in der Umfangsrichtung die Steifigkeit der Scheiben- oder Tellerfeder trotz der Durchbrechungen erhalten, so daß die übertragung selbst größerer Drehmomente sicher möglich ist.The axial fading capacity of the disc or disc spring is therefore significantly increased by increasing the resilient length. In addition, in the circumferential direction the stiffness of the disc or disc spring despite the openings received, so that the transmission of even larger torques is possible safely.
In der Zeichnung ist eine Ausführungsform der erfindungsgemäßen Scheiben- oder Tellerfeder dargestellt.In the drawing is an embodiment of the disc according to the invention or disc spring shown.
Die in der Figur in Ansicht dargestellte Scheiben-oder Tellerfeder 1, die insbesondere zur Verwendung in größeren Kupplungen gedacht ist, weist zwecks Befestigung an einem Ankerring nahe dem äußeren Umfang Bohrungen 2 auf. Zum Festspannen der Scheiben - oder Tellerfeder an dem Kupplungskörper sind nahe dem Innenumfang ebenfalls eine Anzahl von Bohrungen 3 angebracht. Durch Ausstauzungen 4 und 5 sind Schenkel 6, die sich von außen radial nach innen, und Schenkel 7, die sich von innen radial nach außen erstrecken, gebildet. Die Schenkel 6 und 7, die sich nach ihrem Ende zu in der Scheibenebene verjüngen, sind an ihren Enden durch -Schenkel 8- miteinander verbunden. Durch diese Ausbildung der Scheiben- oder- Tellerfeder 1 ist die federnde Länge, die sich aus den Schenkeln 6,7 und den Schenkeln 8 zusammensetzt, zwischen den Einspamiber-eichen erheblich größer als der radiale Abstand der durch die Bohrungen 2 und 3 gegebene Abstand dieser Einspannbereiche.-Daraus ergibt sich ein bedeutend besseres Federungsvermögen der Scheiben- oder Tellerieder trotz des geringen radialen Abstands der Einspannbereiche. The disk or plate spring 1 shown in view in the figure, which is intended in particular for use in larger clutches, has bores 2 near the outer circumference for the purpose of fastening to an anchor ring. A number of bores 3 are also provided near the inner circumference for tightening the disc or plate spring on the coupling body. Legs 6, which extend radially inward from the outside, and legs 7, which extend radially outward from the inside, are formed by damming tongues 4 and 5. The legs 6 and 7, which taper towards their end in the plane of the disk, are connected to one another at their ends by - legs 8-. Through this design of the disc or disc spring 1 , the resilient length, which is composed of the legs 6, 7 and the legs 8 , between the Einspamiber oaks is significantly greater than the radial distance given by the holes 2 and 3 of these Clamping areas.-This results in a significantly better resilience of the disc or plate lowerers despite the small radial distance between the clamping areas.
