According to the invention, a threaded sleeve 2 is arranged on the fixed machine body 1 so as to be able to be rotated, in which threaded sleeve a bearing 3 is axially fixed by its outer shell 4, the inner shell 5 of the bearing 3 being secured on the rotatable machine part 6. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zur axialen Verstellung eines drehbaren Maschinenteils 1 gegenüber einem ortsfesten Maschinenkörper, z. B. einer zylindri­ schen Nabe in einem hohlzylindrischen Lagerstutzen.The invention relates to a device for the axial adjustment of a rotatable machine part 1 relative to a stationary machine body, for. B. a cylindri's hub in a hollow cylindrical bearing socket.

Bisher werden für die Axialeinstellung von Rotations­ teilen meist Einlagen von verschiedener Dicke oder Anzahl verwendet. Das Montieren dieser Einlagen ist schwierig und zeitaufwendig.So far, for the axial adjustment of rotation usually share deposits of different thicknesses or Number used. The assembly of these inserts is difficult and time consuming.

In vielen Fällen, z. B. bei Landmaschinen, wird die axiale Einstellung überhaupt nicht durchgeführt, was aber den Betrieb der jeweiligen Maschine beeinträchtigt und den Verschleiß erhöht. Bei manchen genauen Maschi­ nen, wie zum Beispiel bei den Unterdruck-Sämaschinen, ist die genaue axiale Einstellung der Einzelteile der Aussaateinrichtung zur Anpassung an die jeweilige Größe und Form der Samenkörper eine der wesentlichen Bedin­ gungen für die richtige Funktion der Aussaateinrich­ tung. Es ist notwendig, den Zwischenraum in der Aus­ saateinrichtung genau zu begrenzen, damit die kleinen Samen nicht durchfallen und die spitzen Samen sich nicht verkeilen können. Diese Anpassung was bisher sehr schwierig und zeitaufwendig. Eine fehlende oder unge­ naue Einstellung der Aussaateinrichtung führte zu be­ trächtlichen Ernteverlusten.In many cases, e.g. B. in agricultural machinery, the axial adjustment not done at all but affects the operation of the respective machine and increases wear. With some exact machines such as the vacuum seeder, is the exact axial setting of the individual parts of the Sowing device to adapt to the respective size and shape of the seed body one of the essential conditions conditions for the correct function of the seeding equipment tung. It is necessary to leave the gap in the out to limit the seed facility precisely so that the little ones Seeds do not fall through and the pointed seeds themselves  cannot wedge. This adjustment was very much so far difficult and time consuming. A missing or unsung accurate setting of the sowing device led to be pregnant crop losses.

Aufgabe der Erfindung ist es, eine Vorrichtung zur axialen Verstellung eines drehbaren Maschinenteils, insbesondere der Sichtungsscheibe einer Aussaateinrich­ tung zu schaffen, welche diese Nachteile und Mängel be­ seitigt und die auf einfache Weise genau betätigt werden kann.The object of the invention is a device for axial adjustment of a rotatable machine part, especially the sighting disc of a seeding unit to create, which be these disadvantages and shortcomings sides and actuated precisely in a simple manner can be.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1 solved.

Die erfindungsgemäße Vorrichtung ermöglicht eine stufenlose sehr schnelle und genaue axiale Einstellung bei niedrigen Herstellungskosten, und zwar auch unter erschwerten Bedingungen sowie während des Arbeitsbe­ triebes, was die Produktivität insbesondere einer Sä­ maschine wesentlich erhöht.The device according to the invention enables stepless very fast and precise axial adjustment at low manufacturing costs, even below difficult conditions and during work driven what the productivity in particular a sow machine significantly increased.

Weitere Merkmale und Besonderheiten der Erfindung er­ geben sich aus der folgenden Beschreibung eines in der Zeichnung in schematischem Axialschnitt dargestellten Ausführungsbeispiels.Other features and characteristics of the invention he give themselves one in the following description Drawing shown in a schematic axial section Embodiment.

In einem festen Maschinenkörper 1 ist in zwei Lagern 3, 9 als drehbarer Maschinenteil die Nabe 6 einer Sich­ tungsscheibe 12 gelagert und durch ein Kettenrad 10 angetrieben, das durch Schrauben 11 an der Stirnseite der Nabe 6 befestigt ist. Die Wälzlager 3, 9 sind fest auf der Nabe 6 angeordnet und gegen Axialbewegungen durch Außen- und Innenringe 5 bzw. 8 gesichert. Das zweite Lager 9 ist im ortsfesten Maschinenkörper 1 verschiebbar und nur auf der Nabe 6 fest angeordnet. Das erste Lager 3 ist mittels eines Dichtungsringes 16 abgedichtet und mit seiner Außenschale 4 durch einen Innenring 7 in einer Hülse 2 festgelegt, die im festen Maschinenkörper 1 angeordnet und mit diesem durch ein Gewinde 19 verbunden ist. An der Stirnfläche dieser durch Verdrehen axial bewegbaren Hülse 2 ist eine An­ griffsfläche 15 für einen nicht dargestellten Einstel­ lungsschlüssel vorgesehen. Im Maschinenkörper 1 ist eine radiale Arretierschraube 17 mit einer Kontermutter 18 angeordnet, welche auf die Hülse 2 drückt und sie gegen die Verdrehung und unerwünschte axiale Verschie­ bung sichert. Vor der Sichtungsscheibe 12 sind mit ein­ stellbarem axialem Abstand die Rippen 13 einer Stirn­ wand 14 der Aussaateinrichtung 20 angeordnet.In a fixed machine body 1 , the hub 6 of a sighting disk 12 is mounted in two bearings 3, 9 as a rotatable machine part and driven by a chain wheel 10 , which is fastened by screws 11 to the end face of the hub 6 . The roller bearings 3, 9 are fixed on the hub 6 and secured against axial movements by outer and inner rings 5 and 8, respectively. The second bearing 9 is displaceable in the stationary machine body 1 and is only arranged firmly on the hub 6 . The first bearing 3 is sealed by means of a sealing ring 16 and is fixed with its outer shell 4 by an inner ring 7 in a sleeve 2 which is arranged in the fixed machine body 1 and is connected to it by a thread 19 . On the end face of this axially movable sleeve 2 , a grip surface 15 is provided for a setting key, not shown. In the machine body 1 , a radial locking screw 17 is arranged with a lock nut 18 which presses on the sleeve 2 and secures it against rotation and undesired axial displacement. In front of the viewing window 12 , the ribs 13 of an end wall 14 of the sowing device 20 are arranged with an adjustable axial distance.

Die vorstehend beschriebene Vorrichtung arbeitet wie folgt:The device described above works like follows:

Für die gemeinsame genaue axiale Einstellung der ein­ zelnen Maschinenteile, z. B. der Sichtungsscheibe 12 gegenüber den Rippen 13 der Aussaateinrichtung 20 wird der nicht dargestellte Einstellschlüssel an der An­ griffsfläche 15 der Hülse 2 angesetzt. Nach Lösen der Arretierschraube 17 wird die Hülse 2 im Maschinenteil 1 verdreht, was ihre axiale Verstellbewegung zusammen mit dem ersten Lager 3 und mit der Nabe 6 im festen Maschi­ nenkörper 1 bewirkt. Auf diese Weise wird ein verlang­ tes axiales Spiel eingestellt. Danach wird die Arre­ tierschraube 17 angezogen und durch Festziehen der Mutter 18 gesichert.For the common precise axial setting of a single machine parts, for. B. the viewing window 12 opposite the ribs 13 of the sowing device 20 , the adjustment key, not shown, is attached to the grip surface 15 of the sleeve 2 . After loosening the locking screw 17 , the sleeve 2 is rotated in the machine part 1 , which causes its axial adjustment movement together with the first bearing 3 and with the hub 6 in the fixed machine body 1 . In this way, a required axial play is set. Then the Arre animal screw 17 is tightened and secured by tightening the nut 18 .
