Description
Die Erfindung betrifft eine Achsenführungs- und -positionierkonstruktion, insbesondere eine solche für ein Linearstellglied.The The invention relates to a Achsenführungs- and Positioning construction, in particular such for a linear actuator.
In einem Linearstellglied werden Antriebskomponenten wie ein Motor sowie eine Schnecke und ein Schneckengetriebemodul in erster Linie dazu verwendet, eine Führungsspindel drehend anzutreiben, damit diese ein mit ihr verschraubtes Teleskoprohr verlängert oder verkürzt, wodurch Krankenhausbetten, elektrische Rollstühle und andere Einrichtungen angetrieben werden können, die eine Ausfahr- und/oder Einziehbewegung benötigen. Im Allgemeinen erstreckt sich die Schnecke des Linearstellglieds direkt ausgehend von der Motorwelle, oder sie ist mit dieser verbunden. Die Schnecke (bei der es sich um eine Motorwelle handelt) verfügt über ein freies Ende entfernt vom Motor, wodurch es zu einer einseitigen Lagerung kommt. Daher kann die Schnecke sehr leicht reißen, da während der Übertragung einer Kraft von ihr auf ein Schneckenrad ein großes Drehmoment wirkt.In a linear actuator drive components such as a motor and a worm and a worm gear module in the first place used a lead screw to drive in rotation, so that this one with her screwed telescopic tube extended or shortened, making hospital beds, electric wheelchairs and other facilities can be driven which require an extension and / or retraction movement. In general, extends the worm of the linear actuator directly from the Motor shaft, or it is connected to this. The snail (at which is a motor shaft) has a free end removed from the engine, resulting in a one-sided storage. Therefore The snail can tear very easily, because during the transmission of a force of her acting on a worm wheel a large torque.
Um das Reißen der Schnecke zu vermeiden, wird sie im Allgemeinen aus einem Material hoher Festigkeit hergestellt. Ein derartiges Material führt jedoch zu hohen Material- und Herstellkosten. Der hohe Preis des Gesamterzeugnisses führt dazu, dass dieses nicht in weitem Umfang angewandt werden kann.Around the tearing To avoid the snail, it is generally made of one material made of high strength. However, such a material leads too high material and manufacturing costs. The high price of the whole product leads to this can not be widely applied.
Im
Allgemeinen wird, wie es durch die
Der Erfindung liegt die Aufgabe zugrunde, eine Achsenführungs- und -positionierkonstruktion für ein Linearstellglied zu schaffen, die das freie Ende einer Achse stabil lagern kann.Of the Invention is based on the object, a Achsenführungs- and -positionierkonstruktion for a linear actuator to create, which can store the free end of an axle stable.
Diese Aufgabe ist durch die Achsenführungs- und -positionierkonstruktion gemäß dem beigefügten Anspruch 1 gelöst. Bei ihr ist das freie Ende der Achse durch eine Kappe stabil gelagert, was es ermöglicht, die Achse aus einem Material mit geringerer Festigkeit als bisher herzustellen, wodurch die Material- und Herstellkosten stark gesenkt werden können.These The task is and -positionierkonstruktion according to the appended claim 1 solved. In her the free end of the axle is stably supported by a cap, what makes it possible the axle made of a material with lower strength than before produce, whereby the material and manufacturing costs greatly reduced can be.
Vorzugsweise ist an der Innenwand des Zylinders ein Innenring ausgebildet, um die Unterseite der Kappe zu befestigen, und durch ihn wird verhindert, dass flüssiger Kleber während des Einfüllprozesses für diesen in den Antriebsgrundkörper fließen kann, wodurch verhindert wird, dass die internen Übertragungskomponenten verkleben und nicht mehr ordnungsgemäß arbeiten. Wenn die Kappe im Wesentlichen kegelförmig ausgebildet ist, kann der Kleber leicht und mit größerer Menge eingefüllt werden. Durch Ausbilden rauer Linien und Vertiefungen an der Innenwand des Zylinders und der Außenumfangsfläche der Kappe wird die Verbindungsfestigkeit zwischen der Kappe und dem Zylinder, nachdem der Kleber ausgehärtet ist, verbessert.Preferably is formed on the inner wall of the cylinder, an inner ring to to attach the bottom of the cap, and through it it prevents that more fluid Glue during the filling process For this in the drive body can flow thereby preventing the internal transmission components from sticking together and stop working properly. If the cap is formed substantially conical, can the glue is light and larger in quantity filled become. By forming rough lines and depressions on the inner wall of the cylinder and the outer peripheral surface of the Cap becomes the connection strength between the cap and the Cylinder, after the adhesive has cured, improved.
Die Erfindung wird nachfolgend anhand von durch Figuren veranschaulichten Ausführungsformen näher erläutert.The Invention will now be illustrated by figures embodiments explained in more detail.
