Abstract
Description
Die vorliegende Erfindung betrifft ein Getriebe einer Antriebsvorrichtung einer Jalousie, eines Rolladens, eines Raffstores, einer Markise oder dergleichen zur Untersetzung der Drehzahl von einer Motorwelle zu einer Abtriebswelle.The present invention relates to a gear of a drive device of a blind, a roller shutter, a venetian blind, an awning or the like for reduction the speed from a motor shaft to an output shaft.
Bei bekannten Antriebsvorrichtungen einer Jalousie oder dergleichen ist zwischen einer Motorwelle eines Elektromotors und einer Abtriebswelle ein Getriebe vorgesehen, wobei der Elektromotor das Getriebe zur Wandlung des Drehmoments antreibt. Die Jalousie oder dergleichen muss in einer oberen und einer unteren Endposition, sowie in von einem Benutzer festgelegten Zwischenpositionen anhalten und in dieser Position gehalten werden. Allgemein muss die Jalousie also bei Stillstand, wenn der Elektromotor nicht bestromt wird, in ihrer Position festgehalten werden. Im Stand der Technik ist deshalb eine Bremse vorgesehen, mit der bei Stillstand des Elektromotors, z.B. auch bei einem Ausfall des Elektromotors, die Abtriebswelle festgestellt wird. Beim Anziehen und Lösen der Bremse ist beim Stand der Technik ein deutliches Klicken hörbar. Dies wird vielfach als störend wahrgenommen, insbesondere, wenn bei größeren Fassaden mehrere Jalousien oder dergleichen gleichzeitig betätigt werden.In known drive devices a blind or the like is between a motor shaft Electric motor and an output shaft, a transmission is provided, wherein the electric motor drives the transmission to convert the torque. The blind or the like must be in an upper and a lower one End position, as well as in intermediate positions defined by a user stop and be held in this position. Generally must the blinds at standstill when the electric motor is not energized will be held in place. In the state of the art a brake is therefore provided with which, when the electric motor is at a standstill, e.g. the output shaft even if the electric motor fails is detected. When applying and releasing the brake, the Technology you can hear a clear click. This is often considered a nuisance perceived, especially when there are several blinds or larger façades the same operated simultaneously become.
Aufgabe der vorliegenden Erfindung ist es demgegenüber, ein geräuscharmes Feststellen und Lösen der Abtriebswelle zu ermöglichen.Object of the present invention on the other hand, a low noise Detect and solve to enable the output shaft.
Diese Aufgabe wird durch ein Getriebe der eingangs genannten Art gelöst, bei der das Getriebe ein Schneckengetriebe, ein damit gekoppeltes Schraubradgetriebe und ein mit dem Schraubradgetriebe gekoppeltes Stirnradgetriebe aufweist, welches mit der Abtriebswelle verbindbar ist.This task is done through a gearbox solved of the type mentioned at the beginning, in which the gear is a worm gear, a helical gear coupled to it and a spur gear coupled to the helical gear has, which can be connected to the output shaft.
Durch die Kombination des Schneckengetriebes, des Schraubradgetriebes und des Stirnradgetriebes kann die im Stand der Technik verwendete Bremse vollständig ersetzt werden. Das Schneckengetriebe ist selbsthemmend. Wird die Motorwelle des Elektromotors nicht weiter angetrieben, so hält die Abtriebswelle aufgrund des selbsthemmenden Schneckengetriebes innerhalb kürzester Zeit an. Bei Stillstand ist die Haftreibung zwischen Schnecke und Schneckenrad so groß, dass eine mit dem Getriebe verbundene Abtriebswelle in ihrer Position festgehalten wird. Insbesondere bewirkt die Selbsthemmung, dass die Schnecke nicht durch das Schneckenrad gedreht werden kann. Das Schneckenrad greift in die Schnecke schraubenartig ein. Dadurch ergeben sich im Betrieb geringe Eingriffstöße und eine geringe Geräuschentwicklung. Das Schraubradgetriebe erhöht die Untersetzung. Die Kombination eines Schneckengetriebes und eines Schraubradgetriebes ist deshalb besonders vorteilhaft, weil die Getriebe nicht zueinander justiert werden müssen, wie dies bei einem Kegelradgetriebe der Fall wäre. Eine kompakte Bauweise kann dadurch erreicht werden, dass der Achsenwinkel zwischen der Schnecke und dem Schneckenrad durch den Achsenwinkel zwischen Schraube und Schraubrad des Schraubengetriebes kompensiert wird. Vorzugsweise weisen die Achsenwinkel jeweils 90° auf. Durch das Stirnradgetriebe kann die Abtriebswelle koaxial zur Motorwelle angeordnet werden. Sowohl Motorwelle als auch Abtriebswelle können somit in etwa auf einer Mittelachse der Antriebsvorrichtung angeordnet werden.By combining the worm gear, the helical gear and the spur gear can in the state the brake used in technology can be completely replaced. The worm gear is self-locking. The motor shaft of the electric motor will not continue driven, so holds the output shaft due to the self-locking worm gear within shortest Time on. At standstill there is static friction between the worm and worm wheel so big that an output shaft connected to the gearbox is in position is held. In particular, self-locking means that the worm cannot be turned by the worm wheel. The The worm wheel engages in the worm like a screw. Thereby there are small interventions and low noise during operation. The helical gear increases the Reduction. The combination of a worm gear and one Helical gear is particularly advantageous because the Gearboxes do not have to be adjusted to each other, as is the case with a bevel gearbox would be the case. A compact design can be achieved in that the axis angle between the worm and the worm wheel through the axis angle compensated between screw and screw gear of the screw gear becomes. The axis angles preferably each have 90 °. By the spur gear can drive the output shaft coaxially to the motor shaft to be ordered. Both motor shaft and output shaft can thus arranged approximately on a central axis of the drive device become.
Bei einer besonders bevorzugten Ausführungsform ist die Schnecke des Schneckengetriebes an der Motorwelle ausgebildet. Durch diese Maßnahme bildet ein Teil der Motorwelle bereits die Schnecke des Schneckengetriebes und müssen keine zusätzlichen Bauteile bzw. eine Übertragungseinrichtung von der Motorwelle auf das Schneckengetriebe vorgesehen werden.In a particularly preferred embodiment the worm of the worm gear is formed on the motor shaft. By this measure part of the motor shaft already forms the worm of the worm gear and must No additional Components or a transmission device from the motor shaft to the worm gear.
