Description
Die Erfindung betrifft eine weitere Ausbildung der Schutzvorrichtung für Gelenkwellen, insbesondere an landwirtschaftlichen Maschinen, nach Patent 953 026 für solche Fälle, wo die Schutzvorrichtung nicht an beiden Enden der Gelenkwelle gegen einen festen Maschinenteil abgestützt werden kann. Es ist bekannt, zwischen Wellen und Schutzhüllen ein Wälzlager anzuordnen. Die Anordnung dieses Lagers bei der vorliegenden Schutzvorrichtung bereitet aber insofern Schwierigkeiten, als die mit eimern gewissen notwendigen Spiel zueinandergeführten teleskopartig verschiebbaren Wellenteile keine genaue, d. h. achsengerechte Führung zwischen Rohr und Welle ermöglichen. Auch kommt es im praktischen Betrieb vor, daß die Schutzvorrichtung verbeult oder eingeknickt wird. The invention relates to a further embodiment of the protective device for cardan shafts, in particular on agricultural machinery, according to patent 953 026 for those cases where the protective device cannot be supported against a fixed machine part at both ends of the PTO shaft. It it is known to arrange a roller bearing between shafts and protective covers. The arrangement of this camp with the present protective device, however, causes difficulties as those with buckets of conscience necessary game to each other telescopically displaceable shaft parts no exact, d. H. Enable axis-correct guidance between tube and shaft. It also occurs in practical operation provide for the guard to be dented or buckled.
Nach der Erfindung wird ein Teil des teleskopartig ineinandergesteckten Schutzrohres auf der umlaufenden Welle in an sich bekannter Weise durch ein Wälzlager gelagert, wobei das Wälzlager mit seinem Innen- oder Außenring elastisch nachgiebig abgestützt ist. Vorteilhaft wird zwischen der Welle und dem Innenring des Lagers eine Bunahülse eingezogen. Nach einem weiteren Merkmal der Erfindung ist das Wälzlager durch seitlich angeordnete, mit Vorspannung eingesetzte Scheiben aus nachgiebig elastischem Material in Verbindung mit Halteringen abgedichtet. Es liegt auch im Rahmen der Erfindung, daß ein Rohr der Schutzvorrichtung über einem Gelenk ein trichterförmiges Endstück aus elastisch nachgiebigem Material trägt.According to the invention, a part of the telescopically nested protective tube on the circumferential Shaft mounted in a manner known per se by a roller bearing, the roller bearing with its inner or outer ring is supported in an elastically resilient manner. It is advantageous between the shaft and the inner ring of the bearing retracted a Buna sleeve. According to a further feature of the invention the rolling bearing is made flexible by means of laterally arranged, pretensioned disks elastic material in connection with retaining rings. It is also within the scope of the Invention that a tube of the protective device has a funnel-shaped end piece over a joint made of resilient material.
Die nach der Erfindung vorgeschlagene Ausbildung der Schutzvorrichtung für Gelenkwellen trägt den insbesondere bei landwirtschaftlichen Maschinen gegebenen besonderen Betriebsbedingungen in jeder Hinsicht Rechnung. Die Lagerung der Schutzvorrichtung durch ein elastisch abgestütztes Wälzlager auf der umlaufenden Welle macht die Anordnung unempfindlich gegen Verkantungen und ergibt zugleich eine wirksame Abdichtung des Wälzlagers mit einer Vorratskammer für das Schmiermittel. Dabei ist die Montage außerordentlich 'einfach, und an die Fertigungsgenauigkeit werden keine großen Anforderungen gestellt, so daß eine wirtschaftliche Herstellung gesichert ist:The proposed according to the invention design of the protection device for propeller shafts carries the special operating conditions in particular for agricultural machinery every way bill. The storage of the protective device by an elastically supported roller bearing on the rotating shaft makes the arrangement insensitive to tilting and results at the same time an effective sealing of the rolling bearing with a storage chamber for the lubricant. The assembly is extremely 'simple, and the manufacturing accuracy No great demands are made, so that economical production is ensured:
Die Anordnung eines trichterförmigen Endstückes aus elastisch nachgiebigem Material über einem Gelenk ist besonders geeignet, das Erfindungsproblem zu fördern. Der notwendige große Beu- gungswinkel der Gelenke an landwirtschaftlichen Gelenkwellen würde zu einem so großen Schutztrichter führen, daß derselbe bei den engen Raumverhältnissen, wie sie oft bei Landmaschinen gegeben sind, nicht unterzubringen wäre. Die erfindungsgemäße Verwendung von elastisch nachgiebigem Material für den Schutztrichter gestattet es, denselben genügend klein zu gestalten, ohne daß die Gefahr einer Beschädigung besteht, wenn das Gelenk stärker gebeugt wird. Der Trichter verzieht sich dann seitlich und folgt dem. abgebeugten Wellenteil. Da diese starken Beugewinkel praktisch nur vorübergehend, z. B. beim Wenden der Fahrzeuge, auftreten, wo der Antrieb im allgemeinen ausgeschaltet ist und die Welle nicht umläuft, besteben keine Bedenken, wenn die Gelenk- oder Wellenteile in dieser Situation den Trichter berühren. The arrangement of a funnel-shaped end piece made of resilient material over a Joint is particularly well suited to promoting the invention problem. The necessary big bag The angle of rotation of the joints on agricultural cardan shafts would create such a large protective funnel lead to the same in the tight spaces, as is often the case with agricultural machinery are, could not be accommodated. The inventive use of resilient Material for the protective funnel allows the same to be made sufficiently small without there is a risk of damage if the joint is flexed more. The funnel warps then sideways and follows that. deflected shaft part. Because these strong flexion angles come in handy only temporarily, e.g. B. when turning the vehicles, occur where the drive in general is switched off and the shaft does not rotate, there are no concerns if the joint or Shaft parts touch the funnel in this situation.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Auf einem Ende 4 der Gelenkwelle ist ein Teil 13 des zweiteiligen Schutzrohres durch ein Kugellager 43 gelagert. Zwischen dessen Innenring und der Welle 4 ist eine Büchse 42 aus Buna eingezogen. Seitlich wird das Kugellager 43 durch zwei Scheiben 44 aus Perbunan abgedichtet, die mit Vorspannung gegen die Halteringe 45 und 45' des Kugellagers eingesetzt sind. Innen ist im Rohrteü 13 ein trichterförmiges Endstück 41 aus Perbunan durch die Schrauben 46 befestigt und bildet zugleich die axiale Abstützung des äußeren Halteringes 45' für das Kugellager. Über einen Schmiernippel 47 8g kann letzteres mit Fett versorgt werden. Das elastische, trichterförmige Endstück 41 ist so weit über das Gelenk 5 gezogen, daß ein genügender Unfallschutz gewährleistet ist. Bei gelegentlich vorkommenden, anomal großen Beugungen des Gelenkes kann das elastische Endstück ohne Beschädigungen, folgen.A part 13 is on one end 4 of the cardan shaft of the two-part protective tube supported by a ball bearing 43. Between its inner ring and the Shaft 4 pulled in a sleeve 42 from Buna. The ball bearing 43 is laterally supported by two washers 44 sealed from Perbunan, which is pretensioned against the retaining rings 45 and 45 'of the Ball bearings are used. Inside is in the pipe part 13 a funnel-shaped end piece 41 made of Perbunan is attached by the screws 46 and forms at the same time the axial support of the outer retaining ring 45 'for the ball bearing. Via a grease nipple 47 8g the latter can be supplied with fat. The elastic, funnel-shaped end piece 41 is so far over the joint 5 pulled so that adequate protection against accidents is guaranteed. In the case of occasional abnormally large flexions of the joint can damage the elastic end piece, follow.
