Abstract
Description
Die vorliegende Erfindung betrifft eine lineare Stellvorrichtung und insbesondere eine Stellvorrichtung, die zum Hin- und Herbewegen beliebiger Geräte und Apparate z.B. eines Küchenventilators, eines verstellbaren Krankenbettes, eines Elevators und dgl. eingesetzt werden kann.The The present invention relates to a linear actuator and in particular an adjusting device, which is used for reciprocating any devices and apparatuses e.g. a kitchen fan, an adjustable bed, an elevator and the like used can be.
Eine lineare Stellvorrichtung hat üblicherweise einen Grundkörper, einen Motor, ein Untersetzungsgetriebe, eine Spindel, eine Mutter, ein Stellglied usw. Die Funktionsweise der Stellvorrichtung besteht im Prinzip darin, die Drehbewegung eines Motors durch ein Untersetzungsgetriebe auf die gewünschte Drehzahl zu verzögern, die verzögerte Drehbewegung anschließend auf die Spindel zu übertragen und dann die Drehbewegung der Spindel über die Mutter in eine lineare Bewegung zu übertragen, so dass das zugehörige Stellglied hin- und herbewegt wird, um eine entsprechende Bewegung des zu betätigenden Teils herbeizuführen.A linear actuator has usually a basic body, a motor, a reduction gear, a spindle, a nut, an actuator, etc. The operation of the actuator consists basically, the rotational movement of an engine through a reduction gear to the desired Delay speed, the delayed rotational movement subsequently to transfer to the spindle and then turning the spindle over the nut into a linear one To transmit movement so that the associated Actuator is reciprocated to a corresponding movement of the to be operated Part to bring about.
Eine
herkömmliche
lineare Stellvorrichtung, wie sie in
Durch die vorliegende Erfindung sollen die oben beschriebenen Nachteile herkömmlicher linearer Stellvorrichtungen vermieden oder zumindest gemindert werden.By The present invention is intended to overcome the disadvantages described above conventional linear adjusting devices avoided or at least reduced.
Insbesondere soll eine lineare Stellvorrichtung geschaffen werden, die ein möglichst kleines Volumen und geringen Platzbedarf hat, während die Übertragungsmittel der Stellvorrichtung das Drehmoment möglichst effektiv und weich überträgt. Außerdem soll sie möglichst schwingungsfrei und geräuscharm arbeiten, in einer einfacher Weise zusammengebaut und zerlegt werden können und eine hohe Betriebssicherheit haben.Especially a linear actuator is to be created, the one possible has small volume and small footprint, while the transmission means of the actuator the torque as possible effectively and softly transmits. In addition, should if possible vibration-free and quiet work, be assembled and disassembled in a simple way can and have a high level of operational safety.

Die Übertragungsmittel
Die lineare Stellvorrichtung gemäß der vorliegenden Erfindung hat folgende Vorteile:
- 1) Die Stellvorrichtung hat eine Hülse zur Aufnahme ihrer entsprechenden Einzelteile, die innerhalb der Hülse koaxial untereinander verbunden sind, wodurch das Volumen wie auch der Einbauplatzbedarf der Stellvorrichtung verringert werden.
- 2) Die Einzelteile der Stellvorrichtung sind innerhalb der Hülse koaxial so miteinander verbunden, dass die Achskraft der Stellvorrichtung außerhalb der Hülse aufgenommen wird, wodurch die Übertragungsmittel das Drehmoment sanft und mit optimalem Wirkungsgrad übertragen kann.
- 3) Die Einzelteile der Stellvorrichtung sind im wesentlichen kreisförmig bzw. rotationssymmetrisch ausgebildet, was die Fertigung erleichtert und eine koaxiale Kopplung der Einzelteile ermöglicht, was wiederum Schwingungen und Geräusche dämpft und den Zusammenbau sowie das Zerlegen erleichtert. Außerdem sorgen die Übertragungsmittel der Stellvorrichtung für eine gleichmäßige Verteilung des Drehmomentes, so dass die Drehmomentübertragung äußerst effektiv bei größtmöglichem Drehmomentoutput und kleinstmöglichem Volumen erfolgen kann.
- 1) The adjusting device has a sleeve for receiving their respective items, which are coaxially interconnected within the sleeve, whereby the volume as well as the space requirement of the adjusting device can be reduced.
- 2) The individual parts of the actuator are coaxially connected within the sleeve so that the axial force of the actuator is received outside the sleeve, whereby the transmission means can transmit the torque smoothly and with optimum efficiency.
- 3) The items of the actuator are formed substantially circular or rotationally symmetrical, which facilitates the production and allows a coaxial coupling of the items, which in turn dampens vibrations and noise and facilitates the assembly and disassembly. In addition, the transmission means of the actuator for a uniform distribution of torque, so that the torque transmission can be extremely effective with the greatest possible torque output and smallest possible volume.
