Description
Riemscheiben-, Seilscheiben- oder Stahlbandgetriebe ohne Vorspannung. Die Erfindung betrifft ein Riemscheiben-, Seilscheiben- oder Stahlbandgetriebe ohne Vorspannung, bei dem das Zugmittel durch unter Federwirkung stehende Rollen gegen die Scheiben gedrückt wird.Belt pulley, rope pulley or steel belt drive without pretension. The invention relates to a pulley, pulley or steel belt transmission without Preload, in which the traction mechanism is counteracted by rollers under the action of a spring the discs is pressed.
Um zu verhindern, daß bei derartigen Getrieben eine Überlastung eintritt, wenn die Adhäsion zwischen Scheibe ,und Zugmittel das zulässige Maß überschreitet, wird gemäß der Erfindung der Anpressungsdruck des Zugmittels durch die Spannung im ziehenden Trum geregelt.In order to prevent such gearboxes from becoming overloaded, if the adhesion between the pane and the traction device exceeds the permissible level, According to the invention, the contact pressure of the traction means is caused by the tension regulated in the pulling strand.
Auf -der Zeichnung ist ein Ausführungsbeispiel des neuen Getriebes schematisch dargestellt.On the drawing is an embodiment of the new transmission shown schematically.
Der Riemen i, 2 wird durch die Druckrollen 3, 4 gegen die beiden Scheiben 5 bzw. 6 gedrückt, und zwar bei der ziehenden Scheibe 5 in der Nähe der Ablauf-, bei der gezogenen Scheibe 6 in der Nähe der Auflaufstelle. Die beiden Druckrollen sind an Hebeln 8 bzw. 9 angeordnet, welche um die Achse 7 schwingen, durch eine einstellbare Feder io auseinandergehalten werden und dadurch einen entsprechenden Druck auf die Rollen ausüben. Mit dem Hebel 8 ist der Hebel i i starr verbunden, an dessen Ende eine Rolle 12 angeordnet ist, die das straffe Trum i aus der geraden Richtung drückt. Die Spannkraft dieses Trums hat nun -das Bestreben; den Hebel i i mit dem Hebel 8 und' der Rolle 3 zurückzudrücken und vermindert den von der Rolle 3 auf das zwischen ihr und der Scheibe 5 befindliche Zugorgan ausgeübten Druck um so mehr, je stärker sie wird. Hierdurch erreicht man; daß das Zugmittel rutscht, sobald seine Spannung .das ,durch die Druckfeder io einstellbare Maß überschreitet.The belt i, 2 is pressed against the two pulleys by the pressure rollers 3, 4 5 or 6 pressed, namely with the pulling disk 5 near the drainage, at the drawn disc 6 near the run-up point. The two pressure rollers are arranged on levers 8 and 9, which swing about the axis 7, by a adjustable spring io are kept apart and thereby a corresponding Put pressure on the rollers. The lever i i is rigidly connected to the lever 8, at the end of a roller 12 is arranged, which the tight strand i from the straight Direction pushes. The elasticity of this strand now has the endeavor; the lever i i with the lever 8 and 'to push back the roller 3 and reduce the of the roller 3 on the tension member located between it and the disc 5 by pressure the more the stronger it gets. This achieves; that the traction device slips, as soon as its tension exceeds the level that can be set by the compression spring.
