Description

Schneckengetriebe zur Übertragung der Drehbewegung einer Kurbel auf die Aufzugwelle eines Rouleaus oder Storens Die vorliegendc Erfindung betrifft ein Schneckengetriebe zur Übertragung der Drehbewegung von einer Kurbel auf die hufzugwelle eines Rouleaus oder Storens. Solche Schneckengetriebe müssen selbsthemmend sein, damit sich die Aufzugwelle nicht unter des Gewicht eines nicht aufgewickelten Rouleau- oder Storenabschnittes von selbst drehen kann. Schneckengtriebep deren Schnecke eine sehr kleine Steigung aufweist, , sind ohne weiteres selbs*hemmend. Solche Getriebe eignen sich jedoch nicht gut für den vorgesehenen Zweck weil das Übersetzungsverhältuis unzweokmässig ist. Schneckengetriebe* deren Schnecke eine grosse Steigung aufweist, sind nicht mehr selbsthemmend, so dass sich zusätzliche Massnahmen zur Erzielung einer Selbsthemmung aufdringen. Das Schneckengetriebe nach. der vorliegenden Erfindung weist nun eine ausserordentlich einfache Konstruktion auf, indem die Schnecke mit einem konischen Zapfen versehen ist, der in einer konischen Lagerhülse geführt ist und der zur Erzielung einer Selbsthemmung durch das Gewicht des nicht aufgewickelten Rouleau- oder Storenabschnittes in die Lagerhülse hineingedrückt wird.Worm gear to transmit the rotary motion of a crank the elevator shaft of a blind or blind. The present invention relates to a Worm gear for transferring the rotary motion from a crank to the hoist shaft a roller blind or blind. Such worm gears must be self-locking, so that the winding shaft is not under the weight of an unwound roller or blind section can rotate by itself. Worm gearsep their worm has a very small slope, are easily self-locking. Such gears however, are not well suited for their intended purpose because the gear ratio indispensable is. Worm gears * whose worm has a large pitch are not more self-locking, so that additional measures to achieve a self-locking impose. The worm gear according to. the present invention now has a extraordinarily simple construction, in that the worm with a conical Pin is provided, which is guided in a conical bearing sleeve and to achieve self-locking due to the weight of the unwound blind or blind section is pressed into the bearing sleeve.

Die beiliegende Zeichnung zeigt ein Ausführungsbeispiel der Erfindung, und zwar zeigt die Fig. l einen Axialschnitt durch die Aufzugwelle und die Fig. 2 einen Axialschnitt durch die Schnecke. The accompanying drawing shows an embodiment of the invention, namely, Fig. 1 shows an axial section through the elevator shaft and Fig. 2 shows an axial section through the worm.

Das mit 1 bezeichnete Schneckenrad ist mit der Aufzugwelle 2 mittels eines Dornes 3 verstiftet. Diese Welle 2 ist auf einer Seite des Schneckenrades in einem Kunststofflager 4 und auf deren anderer Seite in einem Kugellager 5 gelagert. The worm wheel designated 1 is connected to the winding shaft 2 by means a pin 3 pinned. This shaft 2 is on one side of the worm wheel stored in a plastic bearing 4 and on the other side in a ball bearing 5.

Das Schneckenrad 1 kämmt mit einer Schnecke 6, , die starr mit einer Antriebswelle 7 verbunden ist , welche in Kunststofflagerhülsen 8 und 9 gelagert ist. Während die Hülse 8 eine zylindrischo Bohrung für den zylindrischen Teil der Welle 1 aufweist, , ist die, Wilse 9 mit einer teilweise konischen Bohrung 9a für einen entsprechenden konischen, als Lagerzapfen dienenden Abschnitt 7a der Welle 7 versehen. All die vorgenannten Labor sind in einem Gehäuse , das aus den beiden Teilern 10 und 11 gebildet wird, festgehalten. Durch das Gewicht der nicht aufgewickelten Abschnittes des Rouleaus oder Storens, das in der Zeichnung durch den Pfeil 12 dargestellt wird, wird der konische Lagerzapfen 7a in die Lagerhülse 9 hineingedrückt, wodurch eine Bremswirkung erzielt wird, die eine Arretierung des Rouleaus odor Storens in Jeder Lage bewirkt.The worm wheel 1 meshes with a worm 6, which is rigid with a Drive shaft 7 is connected, which is mounted in plastic bearing sleeves 8 and 9 is. While the sleeve 8 has a cylindrical bore for the cylindrical part of the Has shaft 1, is the, Wilse 9 with a partially conical bore 9a for a corresponding conical section 7a of the shaft serving as a bearing journal 7 provided. All of the aforementioned laboratory are in one housing that consists of the two Dividers 10 and 11 is formed, recorded. By the weight of the not wound up Section of the roller blind or blind, which is shown in the drawing by the arrow 12 is, the conical bearing pin 7a is pressed into the bearing sleeve 9, whereby a braking effect is achieved, which locks the roller blind odor storens in Every situation causes.
