Description
Die Erfindung betrifft einen Riementrieb mit Spannrolle.The invention relates to a belt drive with a tensioning roller.
Bei den bekannten elastischen Keilriemenspann- und Abstellvorrichtungen besteht die Schwierigkeit, die Spannrollenfeder so auszulegen, daß das erforderliche Antriebsmoment schlupffrei übertragen wird, um den Verschleiß klein zu halten, und kein Riemenflattern auftritt, durch welches der Riemen auf die Keilriemenscheibe aufläuft und abspringt.In the known elastic V-belt tensioning and parking devices, there is the difficulty of designing the tension roller spring so that the required drive torque is transmitted without slippage in order to keep the wear low, and there is no belt flutter, through which the belt runs onto the V-belt pulley and jumps off.
Der Erfindung liegt die Aufgabe zugrunde, die aufgezeigten Nachteile zu vermeiden. Sie wird erfindungsgemäß dadurch gelöst, daß die Spannrolle von einem Hebel gehalten wird, der um einen festen Drehpunkt schwenkbar ist und auf den eine weiche Feder und ein unelastischer, verstellbarer Anschlag in gleicher Drehrichtung einwirken, wobei der Hebel einen Ansatz aufweist, der mit einer Abstellvorrichtung zusammenarbeitet.The invention is based on the object of avoiding the disadvantages indicated. It is achieved according to the invention in that the tensioning roller is held by a lever which is pivotable about a fixed pivot point and on which a soft spring and an inelastic, adjustable stop act in the same direction of rotation, the lever having an attachment that is connected to a parking device cooperates.
Die Spannrolle wird in Richtung auf "Spannen" mit einer weichen Feder belastet, die so ausgelegt ist, daß bei Keilriemenriß mit Sicherheit die Abstellvorrichtung betätigt, jedoch die Vorspannung des Riemens nicht beeinflußt. Vorgespannt wird der Riemen durch einen unelastischen festen Anschlag, der über einen Hebel an der Spannrolle angreift. Der Keilriemen wird wie bei einer starren Spannrolle entsprechend den Vorschriften des Riemenherstellers vorgespannt und erreicht dadurch seine maximale Lebensdauer. Das Flattern des Keilriemens ist bei dieser Anordnung wesentlich geringer als bei einer elastischen Vorspannung und die Gefahr des Abspringens ist nicht gegeben. Außerdem kann die Spannrolle im Zug- wie im Leertrum angeordnet werden.The tensioning pulley is loaded in the direction of "tensioning" with a soft spring, which is designed in such a way that the shut-off device is reliably actuated if the V-belt breaks, however, it does not affect the pretension of the belt. The belt is pretensioned by an inelastic fixed stop that engages the tensioning pulley via a lever. As with a rigid tensioning pulley, the V-belt is pretensioned in accordance with the belt manufacturer's instructions and thus achieves its maximum service life. The fluttering of the V-belt is significantly less with this arrangement than with elastic pretensioning and there is no risk of it jumping off. In addition, the tension pulley can be arranged in the tension as well as in the slack side.
Der Ansatz des Hebels kann auf eine mechanische Abstellvorrichtung einwirken. Es ist jedoch auch gemäß einer Ausgestaltung der Erfindung möglich, daß der Ansatz des Hebels einen Steuerschieber einer hydraulischen Abstellvorrichtung oder einen Schalter einer elektrischen Abstellvorrichtung betätigt.The approach of the lever can act on a mechanical parking device. However, according to one embodiment of the invention, it is also possible that the extension of the lever actuates a control slide of a hydraulic shut-off device or a switch of an electrical shut-off device.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing.
Mit 1 ist eine Antriebsscheibe eines Keilriementriebes bezeichnet, dessen Keilriemen 2 eine Abtriebsscheibe 3 antreibt und durch eine Spannrolle 4 gespannt wird. Die Spannrolle 4 wird von einem Hebel 5 gehalten, der um einen festen Drehpunkt schwenkbar gelagert ist und auf den eine weiche Feder 7 und ein unelastischer, verstellbarer Anschlag 8 in gleicher Drehrichtung einwirken. Der Hebel 5 weist einen Ansatz 9 auf, der mit einem Schalter 10 einer nicht näher dargestellten Abstellvorrichtung zusammenarbeitet.1 with a drive pulley of a V-belt drive is referred to, whose V-belt 2 drives a driven pulley 3 and is tensioned by a tensioning roller 4. The tension roller 4 is held by a lever 5 which is pivotably mounted about a fixed pivot point and on which a soft spring 7 and an inelastic, adjustable stop 8 act in the same direction of rotation. The lever 5 has a projection 9 which cooperates with a switch 10 of a storage device not shown in detail.
Während des Betriebes wird die Spannung des Keilriemens durch den Anschlag 8 aufrechterhalten. Reißt der Keilriemen 2, wird der Hebel 5 durch die Kraft der Feder 7 im Gegenuhrzeigersinn gedreht, wobei der Ansatz 9 den Schalter 10 betätigt.During operation, the tension of the V-belt is maintained by the stop 8. If the V-belt 2 breaks, the lever 5 is rotated counterclockwise by the force of the spring 7, the projection 9 actuating the switch 10.
