Description

Bei Riemenantrieben für Bohrmaschinen ist es notwendig, eine Vorrichtung vorzusehen, durch die der Riemen gespannt wird. Wenn durch den Riemenantrieb auch eine Änderung des Übersetzungsverhältnisses gewünscht wird, ist eine solche Spannvorrichtung meist sehr umständlich und benötigt einen großen Platzbedarf. \lan hat deshalb vorgeschlagen, den Motor verschiebbar einzurichten, aber auch diese Ausführung bedingt meist eine komplizierte Einrichtung.Belt drives for drills require a device be provided through which the belt is tensioned. If by the belt drive too a change of the transmission ratio is desired, is such a tensioning device usually very cumbersome and takes up a lot of space. \ lan has therefore suggested to set up the motor slidably, but this version usually requires a complicated setup.

Uni eine möglichst einfache Riemenspannung zu erreichen, wird gemäß der Erfindung vorgeschlagen, den gesamten Schutzkasten des Riemenantriebes als Motorträger auszubilden und gegenüber der lWirsp edel verschiebbar einzurichten. -Man erhält auf diese Weise eine sehr einfache Verstellung des beweglichen Teiles des Riemenantriebes, da man den Schutzkasten in einfachster Weise auf der Säule der Bohrmaschine verschiebbar anordnen kann.Uni to achieve the simplest possible belt tension is according to the invention proposed the entire protective box of the belt drive as a motor mount to be trained and to be set up so that it can be moved towards the lWirsp. -You get in this way a very simple adjustment of the moving part of the belt drive, because you can move the protective box in the simplest way on the column of the drill can arrange.

1>ei der praktischen Ausführungsform kann zwischen dem oberen Bohrspindellager und dem Schutzkasten oder einer Zwischenrippe in diesem Kasten o. dgl. eine Spannfeder für den Riemenantrieb angeordnet werden. Durch diese Feder wird der Schutzkasten mit dem angehängten Motor ,regen üher der Spindel dauernd unter Spannung gehalten, sc; daß der Riemen den notwendigen Zug erhält. Um den Riemen zu entspannen, z. B. wenn ein anderes L`bersetzungsverhältnis des Riementriebes eingestellt werden soll, wird der Schutzkasten mit einer Zahnstange versehen, in die ein nlit einem Handgriff zu drehendes und in dem \laschinenkörper gelagertes Ritze] eingreift. Durch Verdrehen des Ritzels kann man den Schutzkasten entgegen der Riemenspannfeder verschieben, um darin den Riemen auf andere Riemenscheiben umzulegen.1> In the practical embodiment, between the upper drilling spindle bearing and the protective box or an intermediate rib in this box or the like. A tension spring be arranged for the belt drive. This spring becomes the protective box with the attached motor, rain over the spindle kept under constant tension, sc; that the belt receives the necessary pull. To relax the belt, e.g. B. if a different transmission ratio of the belt drive is to be set, the protective box is provided with a toothed rack into which a handle can be used to be rotated and mounted in the machine body] engages. By twisting of the pinion you can move the protective box against the belt tension spring, to put the belt on other pulleys.

Auf der Zeichnung ist schematisch ein Ausführungsbeispiel eines Riemenantriebes gemäß der Erfindung im Schnitt dargestellt.An exemplary embodiment of a belt drive is shown schematically in the drawing shown according to the invention in section.

Auf dem oberen Ende einer Bohrmaschinensätile i ist gemäß der Erfindung ein Schutzkasten 2 angeordnet, an den der Antriebsmotor 3 fest angeflanscht ist, so daß der Schutzkasten gleichzeitig als \lotorträger dient. Dieser Schutzkasten 2 ist in geeigneter Weise auf dem Kopf .t der Bolirmaschinensäule i geführt, und zwar so, daß er hin find her geschoben werden kann. Die Bohrspindel 5 ist in üblicher «'eise in einem Lager 6 gelagert, das fest mit dem Kopf d der Maschine verbunden ist. Anl Ende der Bohrspindel sind z. B. die beiden Riemenscheiben 7 und Q für den Riemen 9 angebracht. Innerhalb des Schutzkastens 2 befindet sich eine Querrippe io, die eine Querbrücke i i trägt, an der sich das Lagergehäuse 12 einer Zwischell-,velle 13 mit den beiden Riemenscheiben i,1 und 15 befindet. Auf der Motor@velle ist beispielsweise ein Zahnrad 16 befestigt, das über ein Zwischenrad 1,^ (las Zahnrad 08 der Zwischenwelle 13 antreibt.On the upper end of a drilling machine sätile i is according to the invention a protective box 2 is arranged, to which the drive motor 3 is firmly flanged, so that the protective box also serves as a \ lotorträger. This protective box 2 is performed in a suitable manner on the head .t of the Bolir machine column i, and in such a way that it can be pushed back and forth. The drilling spindle 5 is in the usual It is stored in a bearing 6 which is firmly attached to the head of the machine is. At the end of the drilling spindle are z. B. the two pulleys 7 and Q for the Strap 9 attached. Inside the protective box 2 there is a transverse rib io, which carries a cross bridge i i, on which the bearing housing 12 of an intermediate, shaft 13 with the two pulleys i, 1 and 15 is located. For example, on the motor @ shaft a gear 16 is attached, which via an intermediate gear 1, ^ (read gear 08 of the intermediate shaft 13 drives.

Um eine Spannung des Riemen 9 zu erreichen, ist gemäß der Erfindung zwischen deal Bohrspindellager 6 und der Rippe io des Schutzkastens 2 eine Druckfeder i9 angeordnet, die zuni Teil sich in einem Führungsrohr 20 befindet. Durch diese Feder i9 wird der gesamte Schutzkastell 2 gegenüber dein feststehenden Spindellager 6 verschollen, wodurch der Riemen 9 gespannt wird.To achieve tension in the belt 9 is according to the invention between deal drilling spindle bearing 6 and the rib io of the protective box 2 is a compression spring i9 is arranged, the part of which is located in a guide tube 20. Through this Spring i9 becomes the entire protective fort 2 opposite your fixed spindle bearing 6 lost, whereby the belt 9 is tensioned.

Um die Federspannung aufzuheben und z. B. den Riemen 9 von den Riemenscheiben 7 uIld 1,4 auf die anderen Riemenscheiben l; und 15 umzulegen, ist auf der Unterseite des Schutzkastens 2 eine Zahnstange 21 angeordnet, in die ein Ritze] 22 eingreift. Dieses Ritze] ist auf einer Welle 23 befestigt, die in dem Kopf der Bohrmaschinensäule gelagert ist. Außerhalb des Kopfes trägt diese Welle 23 einen Handgriff 2,4, so daß man finit diesem entgegen der Feder 2o den Schutzkasten 2 verschieben kann, um die Riemenspannung aufzuhellen und den Riemen auf die anderen Scheiben umlegen zu können. In der Endstellung kann dieser Hebel 24 mit einer Raste o. dgl. versehen werden, um een Schutzkasten in dieser Lage vorübergehend festzuhalten.To release the spring tension and z. B. the belt 9 from the pulleys 7 uIld 1.4 on the other pulleys l; and 15 fold is on the bottom of the protective box 2, a rack 21 is arranged, in which a slot] 22 engages. This slot] is mounted on a shaft 23 in the head of the drill column is stored. Outside the head, this shaft 23 carries a handle 2, 4, see above that one can finitely move the protective box 2 against the spring 2o, to lighten the belt tension and move the belt to the other pulleys to be able to. In the end position, this lever 24 can be provided with a detent or the like to hold a protective case in this position temporarily.
