Abstract

In a tensioning device for a belt or chain drive in which the bearings (2, 3) of the wheels (4, 5) guiding the belt (11) or the chain are fixed on supporting bodies (1) not displaceable relative to one another and in which at least one of the bearings is flanged to its associated supporting body by means of bolts (7), the distance of one of the fastening bolts (7) from the adjacent bearing (3) can be varied by means of a guide piece (8) which alters the position of the hole (9) for this bolt (7). This makes it possible to tension the belt (11) with the bolt (7) at the bearing (2) to be displaced undone. <IMAGE>

Description

Die Erfindung betrifft eine Spanneinrichtung für einen Riemen- oder Kettentrieb nach dem Oberbegriff des Patent­ anspruchs 1.The invention relates to a clamping device for a Belt or chain drive according to the generic term of the patent claim 1.

Das Spannen solcher Riemen- oder Kettentriebe erfolgt in der Praxis dadurch, daß in der Flanschverbindung in Spann­ richtung ausgerichtete Langlochbohrungen vorgesehen sind und das betreffende Lager bei gelösten Schrauben relativ zu dem benachbarten Lager verschoben wird, wobei nach Er­ reichung der gewünschten Riemen- oder Kettenspannung die Schrauben der Flanschverbindung wieder fest angezogen wer­ den.Such belt or chain drives are tensioned in practice in that in the flange connection in clamping directional elongated holes are provided and the bearing in question with loosened screws relative is moved to the neighboring camp, according to Er the desired belt or chain tension Screw the flange connection tight again the.

Hiervon ausgehend besteht die Aufgabe der Erfindung darin, eine Einrichtung zu schaffen, mit der auf einfache Weise ein gezieltes Verschieben eines Lagers möglich ist.Proceeding from this, the object of the invention is to create a facility with the simple way a targeted shift of a warehouse is possible.

Gelöst wird diese Aufgabe durch eine Einrichtung mit den Merkmalen des kennzeichnenden Teils des Patentanspruchs 1.This task is solved by a facility with the Features of the characterizing part of patent claim 1.

Zweckmäßige Ausgestaltungen sind Gegenstand der Unteran­ sprüche.Appropriate configurations are the subject of the Unteran claims.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt, die einen Riementrieb in Ansicht zeigt.An embodiment is shown in the drawing, which shows a belt drive in view.

Auf einem gemeinsamen Trägerkörper 1 sind in Lagern 2 und 3 geführte Räder 4 und 5 über an den Lagern angreifende Schrauben 6 und 7 befestigt. In dem Lager 2 be­ findet sich ein Führungsstück 8 mit einer zu seiner zylindrischen Außenfläche exzentrischen Bohrung 9. Von dem Führungsstück 8 ragt ein Sechskant 10 aus dem Lager 2 her­ aus. An diesem Sechskant kann das Führungsstück 8 verdreht werden, wodurch der Abstand der Bohrung 9 in Richtung des Lagers 3 verändert werden kann. Hierdurch ist ein Spannen des Riemens 11 möglich.On a common carrier body 1 , bearings 4 and 5 are fastened in bearings 2 and 3 via screws 6 and 7 acting on the bearings. In the bearing 2 there is a guide piece 8 with an eccentric bore 9 to its cylindrical outer surface. A hexagon 10 protrudes from the bearing 2 from the guide piece 8 . The guide piece 8 can be rotated on this hexagon, as a result of which the distance between the bore 9 in the direction of the bearing 3 can be changed. This makes tensioning of the belt 11 possible.

Zur Aufnahme der Schrauben 7 sind in Bohrungen 12 Paßstücke 13 aus z.B. Kunststoff mit Langlöchern drehbar gelagert.To accommodate the screws 7 , 12 adapters 13 made of, for example, plastic with slots are rotatably mounted in bores.
