Description

Die Erfindung betrifft einen Schaftantrieb fĆ¼r eine Webmaschine, der Ɯbertragungselemente enthƤlt, die zum Ɯbertragen von AntriebskrƤften mit WebschƤften verbindbar sind.The invention relates to a shaft drive for a weaving machine, which contains transmission elements, which are connectable for transmitting drive forces with WebschƤften.

Um den VerschleiƟ der Antriebsmittel zu verringern, ist es wĆ¼nschenswert, fĆ¼r wenigstens die Lagerungen der Antriebsmittel eine Schmierung, insbesondere eine Ɩlschmierung vorzusehen. Die bisherigen Versuche in dieser Richtung waren jedoch nicht erfolgreich, da es nicht gelungen ist, die Ɩlschmierungen so abzudichten, dass einerseits kein beim Weben entstehender Staub in den Bereich des Ɩles gelangt und andererseits kein Ɩl in den Bereich des Gewebes gelangt. Schaftantriebe, die sich im Bereich des Gewebes befinden, werden deshalb in der Praxis ohne Ɩlschmierung verwendet.In order to reduce the wear of the drive means, it is desirable to provide lubrication, in particular oil lubrication, for at least the bearings of the drive means. The previous attempts in this direction, however, were unsuccessful, since it has not been able to seal the oil lubrication so that on the one hand no dust arising during weaving gets into the area of the oil and on the other hand no oil gets into the area of the fabric. Shaft drives located in the area of the tissue are therefore used in practice without oil lubrication.

Es ist auch bekannt gewesen (EP 0742298 B1), die Antriebselemente eines Schaftantriebes in einem GehƤuse unterzubringen, das ein Ɩlbad enthƤlt. Das GehƤuse ist mit einem Deckel verschlossen, welcher von vertikalen Stangen durchdrungen wird, die als Ɯbertragungselemente dienen und den Schaftantrieb mit den WebschƤften verbinden. Die Stangen sind ungefĆ¼hrt und fĆ¼hren leichte Schwenkbewegungen aus, um die AntriebskrƤfte auf die WebschƤfte zu Ć¼bertragen. Es erscheint schwierig, die Durchtrittsƶffnungen fĆ¼r die sich auch quer zu den Durchtrittsƶffnungen bewegenden Stangen so abzudichten, dass einerseits kein Staub in das GehƤuse eindringt und andererseits auch kein Ɩl aus dem GehƤuse austritt.It has also been known (EP 0742298 B1) to accommodate the drive elements of a shaft drive in a housing containing an oil bath. The housing is closed with a lid, which of penetrates vertical rods, which serve as transmission elements and connect the shaft drive with the heald frames. The rods are unguided and perform slight pivoting movements to transmit the driving forces to the heald frames. It appears difficult to seal the passages for the also moving transversely to the passages rods so that on the one hand no dust penetrates into the housing and on the other hand, no oil exits the housing.

Der Erfindung liegt die Aufgabe zugrunde, einen Schaftantrieb der eingangs genannten Art so auszubilden, dass eine Ɩlschmierung erhalten wird, wƤhrend jedoch die Gefahr weitgehend ausgeschlossen wird, dass Ɩl zu dem Gewebe gelangen kann oder dass Staub zu dem Ɩl gelangen kann.The invention has the object of providing a shaft drive of the type mentioned in such a way that an oil lubrication is obtained while the risk is largely excluded that oil can get to the tissue or that dust can get to the oil.

Diese Aufgabe wird dadurch gelƶst, dass ein GehƤuse fĆ¼r ein Ɩlbad vorgesehen ist, mit dessen Innenraum mittels LinearfĆ¼hrungen und darin gefĆ¼hrten Ɯbertragungselementen abgedichtet ist.This object is achieved in that a housing is provided for an oil bath, with the interior of which is sealed by means of linear guides and guided therein transfer elements.

Bei dieser Ausbildung sind die LinearfĆ¼hrungen in das GehƤuse integriert, das ein Ɩlbad aufnimmt. Die Antriebsmittel kƶnnen deshalb mit Ɩl besprĆ¼ht werden. Eine wirksame Abdichtung wird durch die in den LinearfĆ¼hrungen gefĆ¼hrten Ɯbertragungselemente und eventuell zugeordnete Dichtungen erreicht.In this embodiment, the linear guides are integrated into the housing, which receives an oil bath. The drive means can therefore be sprayed with oil. An effective seal is achieved by the guided in the linear guides transmission elements and possibly associated seals.

In Ausgestaltung der Erfindung wird vorgesehen, dass der Bereich der Ɯbertragungselemente, der zwischen zwei gegenĆ¼berliegenden LinearfĆ¼hrungen eines Ɯbertragungselementes liegt, mit plattenfƶrmigen Dichtungselementen abgedeckt ist, die mit Dichtungsspalten an die LinearfĆ¼hrungen, an das GehƤuse und an benachbarte Ɯbertragungselemente anschlieƟen. Die plattenfƶrmigen Dichtungselemente bestehen aus einem verschleiƟfesten, mƶglichst leichten Material, das vorzugsweise auch noch ƶlabstoƟende Eigenschaften aufweist. Ein derartiges Material ist beispielsweise Tetrafluorethylen, das unter dem Handelsnamen Teflon bekannt ist. Als Material fĆ¼r die Dichtungselemente kƶnnen auch andere Kunststoffe sowie Metall und insbesondere Metalllegierungen eingesetzt werden.In an embodiment of the invention, it is provided that the region of the transmission elements lying between two opposite linear guides of a transmission element is covered with plate-shaped sealing elements which connect with sealing gaps to the linear guides, to the housing and to adjacent transmission elements. The plate-shaped sealing elements consist of a wear-resistant, as light as possible material, preferably also has oil-repellent properties. Such a material is, for example, tetrafluoroethylene, which is known by the trade name Teflon. As a material for the sealing elements and other plastics and metal and in particular metal alloys can be used.

Eine besonders wirksame Abdichtung wird in weiterer Ausgestaltung der Erfindung dadurch erhalten, dass die LƤnge der Dichtungselemente der Ɯbertragungselemente in LƤngsrichtung der LinearfĆ¼hrungen grĆ¶ĆŸer als der maximale Weg der Ɯbertragungselemente ist. Damit wird erreicht, dass die Dichtungsspalte eine erhebliche LƤnge aufweisen und somit eine gute Dichtungsfunktion bewirken.A particularly effective sealing is obtained in a further embodiment of the invention in that the length of the sealing elements of the transmission elements in the longitudinal direction of the linear guides is greater than the maximum travel of the transmission elements. This ensures that the sealing gaps have a considerable length and thus cause a good sealing function.

Bei einer ersten AusfĆ¼hrungsform wird vorgesehen, dass die plattenfƶrmigen Dichtungselemente benachbarter Ɯbertragungselemente aneinander anliegen. Die plattenfƶrmigen Dichtungselemente benachbarter Ɯbertragungselemente dichten in diesem Fall den Innenraum des GehƤuses in dem Bereich zwischen den LinearfĆ¼hrungen nach auƟen ab. Bei einer anderen AusfĆ¼hrungsform wird vorgesehen, dass zwischen den Dichtungselementen benachbarter Ɯbertragungselemente stationƤre, plattenfƶrmige oder leistenfƶrmige Dichtungselemente angeordnet sind. Die Relativgeschwindigkeit zwischen den miteinander eine Dichtungsfunktion ergebenden Dichtungselementen ist geringer, als wenn die plattenfƶrmigen Dichtungselemente der benachbarten Ɯbertragungselemente direkt zusammen wirken.In a first embodiment it is provided that the plate-shaped sealing elements of adjacent transmission elements abut each other. The plate-shaped sealing elements of adjacent transmission elements in this case seal the interior of the housing in the region between the linear guides to the outside. In another embodiment it is provided that stationary, plate-shaped or strip-shaped sealing elements are arranged between the sealing elements of adjacent transmission elements. The relative velocity between the seal members that provide a sealing function is less than when the plate-shaped seal members of the adjacent transmission members act directly together.

Bei einer anderen AusfĆ¼hrungsform wird vorgesehen, dass die aus den LinearfĆ¼hrungen herausbewegbaren Endabschnitte der Ɯbertragungselemente mittels balgartigen Dichtungselementen gegenĆ¼ber dem Innenraum des GehƤuses abgeschlossen sind.In another embodiment, it is provided that the end sections of the transmission elements which can be moved out of the linear guides are closed by means of bellows-type sealing elements with respect to the interior of the housing.

Bei einer weiteren AusfĆ¼hrungsform der Erfindung wird vorgesehen, dass das GehƤuse im Bereich der Enden der LinearfĆ¼hrungen mit einem Deckel verschlossen ist, der fĆ¼r die Ɯbertragungsmittel mit Durchtrittƶffnungen versehen ist, die Dichtungselemente aufweisen.In a further embodiment of the invention it is provided that the housing is closed in the region of the ends of the linear guides with a lid which is provided for the transmission means with passage openings, which have sealing elements.

Um das GehƤuse 10 und die AnsƤtze 16 im Bereich der LinearfĆ¼hrungen 13, 14 und der Ɯbertragungselemente 11, 12 nach auƟen abzudichten, sind bei dem AusfĆ¼hrungsbeispiel nach Fig. 2 und 3 an den Ɯbertragungselementen 11, 12 plattenfƶrmige Dichtungselemente 17, 18 angebracht, wie dies fĆ¼r das Ɯbertragungselement 12 dargestellt ist. Die plattenfƶrmigen Dichtungselemente 17, 18 erstrecken sich Ć¼ber die gesamte Breite zwischen den gegenĆ¼berliegenden LinearfĆ¼hrungen 13, 14, mit welchen sie Dichtungsspalte bilden. Bei dem AusfĆ¼hrungsbeispiel haben die plattenfƶrmigen Dichtungselemente 17, 18 eine Dicke entsprechend den Seitenstegen der LinearfĆ¼hrungen 13, 14, so dass die in Fig. 2 nicht sichtbaren benachbarten Ɯbertragungselemente 12, die ebenfalls mit plattenfƶrmigen Dichtungselementen 17, 18 versehen sind, unter Bildung eines Dichtungsspaltes an dem Dichtungselement 17 oder 18 des benachbarten Ɯbertragungselementes anliegt. Wie aus Fig. 3a und 3b zu ersehen ist, ist die LƤnge L der Dichtungselemente 17, 18 in LƤngsrichtung der LinearfĆ¼hrungen 13, 14 grĆ¶ĆŸer als der maximale Weg H der Ɯbertragungselemente 12. Dadurch ergibt sich ein Bereich A, in welchem sich die Dichtungselemente 17, 18 benachbarter Ɯbertragungselemente immer Ć¼berlappen, so dass immer eine sichere Dichtung gewƤhrleistet ist.In order to seal the housing 10 and the projections 16 in the region of the linear guides 13, 14 and the transmission elements 11, 12 to the outside, in the embodiment of FIGS. 2 and 3 to the transmission elements 11, 12 plate-shaped sealing elements 17, 18 are attached, as for the transmission element 12 is shown. The plate-shaped sealing elements 17, 18 extend over the entire width between the opposite linear guides 13, 14, with which they form sealing gaps. In the embodiment, the plate-shaped sealing members 17, 18 have a thickness corresponding to the side bars of the linear guides 13, 14, so that the not visible in Fig. 2 adjacent transmission elements 12, which are also provided with plate-shaped sealing elements 17, 18, to form a sealing gap the sealing element 17 or 18 of the adjacent transmission element rests. As can be seen from FIGS. 3 a and 3 b, the length L of the sealing elements 17, 18 in the longitudinal direction of the linear guides 13, 14 is greater than the maximum distance H of the transmission elements 12. This results in a region A, in which the sealing elements 17 , 18 adjacent transmission elements always overlap, so that always a secure seal is guaranteed.

FĆ¼r die plattenfƶrmigen Dichtungselemente 17, 18 wird ein Werkstoff gewƤhlt, der mƶglichst leicht ist, jedoch verschleiƟfest ist. FĆ¼r diesen Zweck hat sich Tetrafluorethylen, Handelsname Teflon, als geeignet erwiesen. Es kƶnnen Dichtungselemente 17, 18 vorgesehen werden, die vollstƤndig aus diesem Material bestehen oder mit diesem Material beschichtet sind. DarĆ¼ber hinaus sind jedoch auch Metalle oder Metalllegierungen als Dichtungselemente 17, 18 geeignet.For the plate-shaped sealing elements 17, 18, a material is selected which is as light as possible, but is wear-resistant. For this purpose, tetrafluoroethylene, trade name Teflon, has proved suitable. There may be provided sealing elements 17, 18 which are made entirely of this material or coated with this material. In addition, however, metals or metal alloys are also suitable as sealing elements 17, 18.

Die AnsƤtze 16 des GehƤuses 10 enden in dem Bereich A. Die plattenfƶrmigen Dichtungselemente 17 oder 18 dichten auch gegenĆ¼ber den Enden der AnsƤtze 16 ab.The lugs 16 of the housing 10 terminate in the area A. The plate-shaped sealing elements 17 or 18 also seal against the ends of the lugs 16.

Bei der AusfĆ¼hrungsform nach Fig. 4 und 5 ist die Dicke der plattenfƶrmigen Dichtungselemente 19, 20 der Ɯbertragungselemente 12 geringer als bei dem AusfĆ¼hrungsbeispiel nach Fig. 2 und 3. Zwischen den Dichtungselementen 19, 20 der benachbarten Ɯbertragungselemente 12 sind stationƤre leistenfƶrmige Dichtungselemente 21 angeordnet, die sich zwischen den einander gegenĆ¼berliegenden LinearfĆ¼hrungen 13, 14 erstrecken. Die LƤnge der plattenfƶrmigen Dichtungselemente 19, 20 in Richtung der LinearfĆ¼hrung 13, 14 ist grĆ¶ĆŸer als der maximale Weg, so dass auch hier ein Ɯberlappungsbereich A vorhanden ist, in welchem die benachbarten Dichtungselemente 19, 20 sich Ć¼berlappen, auch wenn die benachbarten Ɯbertragungselemente sich in den jeweils ƤuƟersten Positionen befinden. In diesem Bereich A sind die stationƤren leistenfƶrmigen Dichtungselemente 21 angeordnet. Die leistenfƶrmigen Dichtungselemente 21 kƶnnen aus dem gleichen Material wie die Dichtungselemente 17, 18 oder 19, 20 bestehen, oder auch aus einem anderen Material.In the embodiment according to FIGS. 4 and 5, the thickness of the plate-shaped sealing elements 19, 20 of the transmission elements 12 is smaller than in the embodiment according to FIGS. 2 and 3. Between the sealing elements 19, 20 of the adjacent transmission elements 12 stationary strip-shaped sealing elements 21 are arranged, which extend between the mutually opposite linear guides 13, 14. The length of the plate-shaped sealing elements 19, 20 in the direction of the linear guide 13, 14 is greater than the maximum distance, so that here too an overlap area A is present, in which the adjacent sealing elements 19, 20 overlap, even if the adjacent transmission elements in the outermost positions. In this area A, the stationary strip-shaped sealing elements 21 are arranged. The strip-shaped sealing elements 21 may be made of the same material as the sealing elements 17, 18 or 19, 20, or of another material.

Das AusfĆ¼hrungsbeispiel nach Fig. 6a und 6b entspricht im Prinzip dem AusfĆ¼hrungsbeispiel nach Fig. 4 und 5. Auch bei diesem AusfĆ¼hrungsbeispiel sind die Ɯbertragungselemente 12 mit plattenfƶrmigen Dichtungselementen 19, 20 versehen, die sich zwischen den einander gegenĆ¼berliegenden LinearfĆ¼hrungen 13, 14 erstrecken. Zwischen den benachbarten Ɯbertragungselementen, d.h. zwischen den benachbarten Dichtungselementen 19, 20 der benachbarten Ɯbertragungselemente 12 sind jedoch drei leistenfƶrmige, stationƤre Dichtungselemente 22, 23, 24 vorgesehen. Das stationƤre Dichtungselement 22 befindet sich in dem Ɯberlappungsbereich A. Die Dichtungselemente 23, 24 befinden sich darĆ¼ber und darunter. Sie dienen jeweils als eine Art Abstreifer. WƤhrend das Dichtungselement 23 dafĆ¼r sorgt, dass mƶglicherweise anhaftender Staub abgestreift wird, sorgt das Dichtungselement 24 dafĆ¼r, dass Ć¼berschĆ¼ssiges Ɩl abgestreift wird. Zwischen den Dichtungselementen 23, 24 ist eine BlasdĆ¼se 26 angeordnet, die an eine Druckluftquelle angeschlossen ist und die einerseits Staub und andererseits Ɩl zurĆ¼ckblƤst.The embodiment of Fig. 6a and 6b corresponds in principle to the embodiment of FIGS. 4 and 5. Also in this embodiment, the transmission elements 12 are provided with plate-shaped sealing elements 19, 20 which extend between the mutually opposite linear guides 13, 14. Between the adjacent transmission elements, ie between the adjacent sealing elements 19, 20 of the adjacent transmission elements 12, however, three strip-shaped, stationary sealing elements 22, 23, 24 are provided. The stationary seal member 22 is located in the overlap area A. The seal members 23, 24 are located above and below. They each serve as a kind of scraper. While the sealing member 23 ensures that any adhering dust is stripped, the sealing member 24 ensures that excess oil is stripped off. Between the sealing elements 23, 24, a blowing nozzle 26 is arranged, which is connected to a compressed air source and on the one hand blows back dust and oil.

Bei der AusfĆ¼hrungsform nach Fig. 7a und 7b wird die Abdichtung dadurch verstƤrkt, dass die Dichtungsspalten dadurch verlƤngert werden, dass sich die stationƤren Dichtelemente 25 weit Ć¼ber den Ɯberlappungsbereich A der plattenfƶrmigen Dichtungselemente 19, 20 sowohl nach innen zum GehƤuseinneren als auch nach auƟen erstrecken.In the embodiment of Figures 7a and 7b, the seal is reinforced by extending the sealing gaps by extending the stationary sealing elements 25 far inwardly beyond the overlapping area A of the plate-shaped sealing elements 19, 20 both inside and outside the housing.

Die Dichtungswirkung lƤsst sich dadurch erhƶhen, dass die LƤnge der Dichtungsspalte vergrĆ¶ĆŸert wird, wozu die LinearfĆ¼hrungen 13', 14' und die plattenfƶrmigen Dichtungselemente 19, 20 sowie die stationƤren Dichtungselemente wesentlich verlƤngert werden, wie das in Fig. 8a, 8b und 9a, 9b dargestellt ist. Dabei kƶnnen die LinearfĆ¼hrungen 13", 14" auch in ihrer LƤngsrichtung unterteilt sein.The sealing effect can be increased by increasing the length of the sealing gaps, for which purpose the linear guides 13 ', 14' and the plate-shaped sealing elements 19, 20 and the stationary sealing elements are substantially extended, as in FIGS. 8a, 8b and 9a, 9b is shown. The linear guides 13 ", 14" can also be subdivided in their longitudinal direction.

Die AusfĆ¼hrungsform nach Fig. 10 und 11 entspricht im Prinzip der AusfĆ¼hrungsform nach Fig. 4 und 5. Es sind beispielsweise drei schmale, leistenfƶrmige Dichtungselemente 27 vorgesehen, die sich zwischen den einander gegenĆ¼berliegenden Schenkeln der LinearfĆ¼hrungen 13, 14 befinden. Diese leistenartigen Dichtungselemente 27 sind jeweils an den Grenzen und in der Mitte des Ɯberlappungsbereiches A vorgesehen. Die beiden ƤuƟeren Dichtungselemente 27 kƶnnen dabei im wesentlichen als Abstreifelemente ausgestaltet sein, wƤhrend das mittlere Dichtungselement 27 dann das eigentliche Dichtungselement ist.The embodiment of FIGS. 10 and 11 corresponds in principle to the embodiment of FIGS. 4 and 5. There are, for example, three narrow, strip-shaped sealing elements 27 are provided, which are located between the opposite legs of the linear guides 13, 14. These strip-like sealing elements 27 are provided at the boundaries and in the middle of the overlapping area A, respectively. The two outer sealing elements 27 may be configured substantially as a stripping, while the middle seal member 27 is then the actual sealing element.
