Abstract
Description
Die Erfindung betrifft eine Kupplungs-Bremskombination nach dem Oberbegriff des Anspruchs 1.The invention relates to a clutch-brake combination according to the preamble of
Kupplungs-Bremskombinationen werden unter anderem für Webmaschinenantriebe, aber auch für Werkzeugmaschinen, Verpackungs- und Druckmaschinen sowie Handhabungsgeräte verwendet. Sie dienen zum Kuppeln einer Antriebswelle mit einer Abtriebswelle und zum Abbremsen der Abtriebswelle bei geöffneter Kupplung innerhalb kürzester Zeit. Insbesondere bei Webmaschinen werden hohe Anforderungen gestellt. So muss die Abtriebswelle im Falle eines Fehlers innerhalb möglichst kleiner Nachlaufwinkel bei Drehzahlen bis ca. 2500 U/min stillgesetzt werden. Hierdurch wird das Material der Kupplungs-Bremskombination durch die dynamischen Trägheitskräfte hohen Spitzenbelastungen ausgesetzt. Trotzdem werden ein präzises Arbeiten über die gesamte Lebensdauer und lange Standzeiten der Kupplungs-Bremskombination erwartet.Clutch brake combinations are used, among others, for weaving machine drives, but also for machine tools, packaging and printing machines and handling equipment. They serve to couple a drive shaft with an output shaft and to decelerate the output shaft with the clutch open within a very short time. In particular, in looms high demands are made. So the output shaft must be stopped in the event of a fault within the smallest possible caster angle at speeds up to about 2500 rev / min. As a result, the material of the clutch-brake combination is exposed by the dynamic inertia forces high peak loads. Nevertheless, a precise work over the entire service life and long service life of the clutch-brake combination are expected.

Der Erfindung liegt die Aufgabe zugrunde, eine Kupplungs-Bremskombination so zu gestalten, dass sie kostengünstig hergestellt werden kann und im Dauerbetrieb sehr wenige und lange Wartungsintervalle ermöglicht. Außerdem kann im gleichen Bauraum eine größere elektrische Leistung bzw. in einem kleineren Bauraum eine gleiche Leistung untergebracht werden. Die Aufgabe wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention has for its object to make a clutch-brake combination so that they can be produced inexpensively and allows continuous operation very few and long maintenance intervals. In addition, in the same space a larger electric power or in a smaller space equivalent power can be accommodated. The object is achieved according to the invention by the features of
Nach der Erfindung ist die Magnetspule des Bremsmagneten mittels einer Kunststoffmasse hoher Festigkeit in einem Spritzgießverfahren an einer als Rückflussplatte dienenden Deckscheibe befestigt, die an der nach außen weisenden Stirnseite der Magnetspule angeordnet ist, indem die Kunststoffmasse beim Spritzgießen in Hinterschneidungen der im Wesentlichen flachen Deckscheibe eindringt. Alternativ oder in Kombination mit der erfindungsgemäßen Gestaltung des Bremsmagneten kann der Kupplungsmagnet ebenfalls in gleicher Weise mittels einer Kunststoffmasse an einer als Rückflussplatte dienenden Deckscheibe befestigt sein. Dabei werden die Hinterschneidungen gemäß einer Ausgestaltung der Erfindung zweckmäßigerweise durch Öffnungen in den Deckscheiben gebildet, die sich nach außen erweitern. Die Hinterschneidungen können auch schwalbenschwanzförmige Nuten in der der zugeordneten Magnetspule zugewandten Stirnseite der jeweiligen Deckscheibe sein. Die Deckscheiben haben gegenüber den bekannten Magnetspulengehäusen ein geringeres Gewicht und sind einfacher zu fertigen.According to the invention, the magnetic coil of the brake magnet is fixed by means of a plastic material of high strength in an injection molding on serving as a reflux plate cover, which is arranged on the outwardly facing end side of the magnetic coil by the plastic material penetrates during injection molding in undercuts the substantially flat cover plate. Alternatively or in combination with the design of the brake magnet according to the invention, the coupling magnet can likewise be fastened in the same way by means of a plastic compound to a cover plate serving as a reflux plate. The undercuts are advantageously formed in accordance with an embodiment of the invention by openings in the cover plates, which expand to the outside. The undercuts may also be dovetailed grooves in the associated magnetic coil facing end side of the respective cover plate. The cover plates have a lower weight compared to the known magnetic coil housings and are easier to manufacture.
Um einen günstigen magnetischen Rückfluss zu gewährleisten, überdecken die Polringe die Deckscheiben an deren äußeren Umfängen mit geringem Spiel. Im Falle des Kupplungsmagneten ermöglicht das Spiel eine Relativbewegung zwischen der mit der Deckscheibe verbundenen Magnetspule und dem Polrad, während im Falle des Bremsmagneten das Spiel dafür sorgt, dass der Magnetfluss beim Abschalten des Magneten sofort unterbrochen wird und keine Einflüsse durch Restmagnetismus den Schaltvorgang beeinträchtigen.In order to ensure a favorable magnetic reflux, the pole rings cover the cover disks at their outer peripheries with little play. In the case of the clutch magnet, the play allows a relative movement between the magnetic disk connected to the cover disk and the pole wheel, while in the case of the brake magnet, the clearance ensures that the magnetic flux is interrupted immediately when switching off the magnet and no influences by residual magnetism affect the switching process.
Gemäß einer Ausgestaltung der Erfindung wird der Magnetfluss am inneren Bereich der Deckscheibe des Bremsmagneten dadurch erreicht, dass die Deckscheibe den Polring stirnseitig überlappt und an diesem festgeschraubt ist. Aus dem gleichen Grund wird gemäß einer weiteren Ausgestaltung der Erfindung vorgeschlagen, dass die Deckscheibe des Kupplungsmagneten im Bereich ihrer inneren Begrenzung den Polring stirnseitig überlappt und in dem überlappenden Bereich einen axial nach innen gerichteten Kragen aufweist, der stirnseitig nahe an den Polring reicht. Ein geringer Abstand ist in diesem Fall erforderlich, da der Polring relativ zur Deckscheibe des Kupplungsmagneten drehbar sein muss. Der Kragen kann dabei an seinem äußeren Umfang eine Hinterschneidung aufweisen, z. B. dadurch, dass sich der Durchmesser des Kragens nach außen zur Stirnseite der Deckscheibe hin verkleinert oder dass der Kragen an seinem äußeren Umfang eine Ringnut aufweist.According to one embodiment of the invention, the magnetic flux at the inner region of the cover plate of the brake magnet is achieved in that the cover plate overlaps the pole ring on the front side and is screwed tightly thereto. For the same reason, it is proposed according to a further embodiment of the invention that the cover plate of the coupling magnet in the region of its inner boundary overlaps the pole ring on the front side and in the overlapping region has an axially inwardly directed collar which reaches the end side close to the pole ring. A small distance is required in this case, since the pole ring must be rotatable relative to the cover plate of the clutch magnet. The collar can have an undercut at its outer periphery, z. B. in that the diameter of the collar decreases outwardly towards the end face of the cover plate or that the collar has an annular groove on its outer periphery.
Da das Gehäuse des Elektromagneten entfällt, muss die Kunststoffmasse den mechanischen und dynamischen Belastungen während des Betriebs standhalten. Es wird daher vorgeschlagen, dass eine Kunststoffmasse gewählt wird, die nach
