 der andern Richtung bringt dagegen eine Lockerung der Federwindungen mit sich, so dass sich die
Feder leicht auf das Rohr aufschieben lässt, wenn die entsprechende Relativdrehung im Gegendrehsinn erfolgt. Um beim Aufbringen der Feder auf das Schutzrohr ein Kratzen des freien Federendes zu vermeiden und eine Handhabe für das Aufdrehen der Feder im Sinne einer Lockerung der
Federwindungen zu erreichen, steht das freie Federende erfindungsgemäss vom Schutzrohr ab. 



   Bei langen Wellen werden diese häufig durch ein Zwischenlager unterstützt, wobei dann beiderseits des Wellenlagers zwei Schutzrohre angeordnet werden. In diesem Fall kann für beide
Schutzrohre eine gemeinsame Biegefeder vorgesehen werden, die aus zwei gewundenen Abschnitten und einem diese verbindenden, den abgestützten Schenkel bildenden Bügel besteht. 



   In den Zeichnungen ist der Erfindungsgegenstand beispielsweise dargestellt, u. zw. zeigen Fig. l eine Schutzvorrichtung für eine Welle mit einem mittleren Wellenlager in Ansicht und Fig. 2 im Querschnitt nach der Linie 11-11 der   Fig. 1.   



   Die Welle-l-dient beispielsweise zum Antrieb des Roll oder Kratzbodens eines Ladewagens oder Düngerstreuers und ist an der einen Fahrzeuglängsseite von vorne nach hinten zum Getriebe des Roll-oder Kratzbodens geführt. Die Welle besitzt ein mittleres   Lager-2-,   das bei der Montage auf die Welle aufgeschoben und dann an einen entsprechenden   Befestigungsteil--3--des   Fahrzeuges angeschraubt wird. Beiderseits des Wellenlagers-2-ist je ein die Welle-l-mit beträchtlichem Radialspiel umhüllendes Schutzrohr--4--angeordnet.

   Zur Verdrehsicherung der beiden-   Schutzrohre --4-- dient   eine gemeinsame gewundene Biegefeder, die aus zwei gewundenen   Abschnitten --5-- und   einem diese verbindenden   Bügel--6--besteht.   Die Abschnitte-S-umschliessen die Enden der Schutzrohre --4-- mehrfach mit radial nach innen gerichteter Vorspannung, während der   Bügel --6-- einen   abstehenden Federschenkel bildet, der am Lager   --2-- bzw. Befestigungsteil-3-abgestützt   ist. Die freien   Enden --7-- der   Feder sind vom   Schutzrohr --4-- radial   abgebogen. Vom   Bügel-6-aus   sind die beiden Abschnitte-5jeweils in der durch Pfeil angegebenen Wellendrehrichtung gewunden. 



   PATENTANSPRÜCHE : 
1. Schutzvorrichtung für freiliegende Wellen, insbesondere für die Kratzbodenantriebswelle landwirtschaftlicher Fahrzeuge, bestehend aus wenigstens einem die Welle mit radialem Spiel umhüllenden, ausschliesslich von der Welle getragenen Schutzrohr, vorzugsweise aus Kunststoff, g e k e n n z e i c h n e t d u r c h wenigstens eine das Schutzrohr (4) mit radial nach innen gerichteter Vorspannung mehrfach umschliessende gewundene Biegefeder (5, 6), von der ein abstehender Schenkel (6) an einem drehfesten Bauteil (2, 3) abgestützt ist.

 the other direction, however, brings about a loosening of the spring coils so that the
The spring can be easily pushed onto the tube if the corresponding relative rotation takes place in the opposite direction. In order to avoid scratching the free end of the spring when the spring is applied to the protective tube and to provide a handle for unscrewing the spring in the sense of loosening the
To achieve spring coils, the free spring end protrudes from the protective tube according to the invention.



   In the case of long shafts, these are often supported by an intermediate bearing, with two protective tubes then being arranged on both sides of the shaft bearing. In this case it can be for both
Protective tubes a common spiral spring are provided, which consists of two coiled sections and a bracket connecting them and forming the supported leg.



   In the drawings, the subject matter of the invention is illustrated, for example, FIG. 1 shows a protective device for a shaft with a central shaft bearing in a view, and FIG. 2 shows a cross-section along the line 11-11 of FIG. 1.



   The shaft-1-serves, for example, to drive the roller or scraper floor of a loading wagon or fertilizer spreader and is guided on one longitudinal side of the vehicle from front to back to the gearing of the roller or scraper floor. The shaft has a middle bearing-2, which is pushed onto the shaft during assembly and then screwed to a corresponding fastening part 3 of the vehicle. On both sides of the shaft bearing-2-a protective tube-4-enveloping the shaft-1-with considerable radial play is arranged.

   A common coiled spiral spring, which consists of two coiled sections --5 - and a bracket connecting these - 6 - is used to prevent the two protective tubes from twisting. The sections-S-enclose the ends of the protective tubes --4-- several times with radially inwardly directed prestressing, while the bracket --6-- forms a protruding spring leg that is attached to the bearing --2-- or fastening part-3- is supported. The free ends --7-- of the spring are bent radially from the protective tube --4--. From the bracket 6, the two sections 5 are each wound in the direction of shaft rotation indicated by the arrow.



   PATENT CLAIMS:
1. Protection device for exposed shafts, in particular for the scraper floor drive shaft of agricultural vehicles, consisting of at least one protective tube, preferably made of plastic, which envelops the shaft with radial play and is carried exclusively by the shaft, characterized by at least one protective tube (4) with radially inwardly directed prestress Coiled spiral spring (5, 6) enclosing several times, from which a protruding leg (6) is supported on a non-rotatable component (2, 3).
