Abstract
Description
Verfahren bei der Herstellung einer drehbaren Ver-Process in the production of a rotatable
bindung zweier Bauteile Die Erfindung betrifft ein Verfahren bei der Herstellung einer drehbaren Verbindung zweier Bauteile unter Zwischenschaltung von Wälzkörpern, insbes. Kugeln, die an mindestens zwei parallel zueinander angeordneten Ringen, insbes. aus Stahldraht abgestützt sind, insbes an den Ringen anliegen, die in jeden, insbes. im Bereich der Drehlagerung aus Kunststoff bestehenden Bauteil eingebettet sind Bei einem Verfahren dieser Art wurde es bekannt, das Einbetten der Laufringe zeitlich nach der Herstellung der Kunststoffbauteile, mittels Ultraschall, mittels Wärme oder auch kalt, durchzuführen. Dies ist relativ kompliziert und erfordert einen gesonderten Arbeitsgang und auch besonderer Einrichtungen. Der Erfindung liegt die Aufgabe zugrunde, hier eine Vereinfachung zu treffen. Erreicht wird dies, wenn bei einem Verfahren der eingangs erwähnten Art, gemäß der Erfindung die Ringe gleichzeitig mit dem Spritzen der Bauteile in diese eingebettet werden. Durch das erfindungsgemäße Verfahren wird die drehbare Verbindung sofort bei der Herstellung der Bauteile geschaffen, sodaß ein nachträgliches Ausarbeiten irgendwelcher Paßflächen mit den damit verbundenen Schwierigkeiten entfallen kann und die Herstellung der Drehverbindung damit rationeller und billiger erfolgen kann. Die beiden Bauteile, die drehbar miteinander zu verbinden sind, können dabei beliebige Form aufweisen. Die Ringe besitzen bevorzugt Kreisquerschnitt. Der Kunststoffteil muß nicht zwingend zylindrische Gestalt aufweisen. Die Wälzkörper sind, wie dies auch bei Kugellagern üblich ist, in Käfigen gelagert und solcherart voneinander im Abstand gehalten. Die Ringe können an einer Stelle geschlitzt sein, wodurch eine gewisse federnde Eigenschaft erhalten wird. Erfindungsgemäß hergestellte Drehlagerungen, die insbes. in der Feinmechanik Verwendung finden, besitzen eine hohe Eigendämpfung. Weiters sind die beiden drehbar miteinander verbundenen Bauteile elektrisch voneinander isoliert, ohne daß für den Aufbau des Lagers nur elektrisch nichtleitendes Material (z.B. Wälzkörper aus nicht leitendem Material, z.B. Glas) verwendet werden.binding two components The invention relates to a method in the Creation of a rotatable connection between two components with the interposition of Rolling bodies, esp. Balls, which are arranged on at least two parallel to each other Rings, esp. Are supported from steel wire, especially rest on the rings that in every component made of plastic, especially in the area of the pivot bearing embedded In a procedure of this type it became known the embedding of the race rings after the manufacture of the plastic components, by means of ultrasound, by means of heat or cold. This is relative complicated and requires a separate operation and special facilities. The invention is based on the object of simplifying this. Achieved this is, if in a method of the type mentioned at the outset, according to the invention the rings are embedded in the components at the same time as the injection molding process. The inventive method, the rotatable connection is immediately at the Manufacture of the components created, so that a subsequent elaboration of any Mating surfaces with the associated difficulties can be omitted and the production the slewing ring can thus be made more rational and cheaper. The two components which are to be rotatably connected to one another can have any shape. The rings preferably have a circular cross-section. The plastic part does not have to be have a cylindrical shape. The rolling elements are, as is the case with ball bearings It is common to store them in cages and keep them at a distance from one another in this way. The rings can be slotted at one point, creating a certain resilience Property is preserved. Pivot bearings produced according to the invention, the esp. Used in precision engineering, they have a high level of self-damping. Furthermore are the two rotatably interconnected components electrically from each other insulated without using only electrically non-conductive material for the construction of the bearing (e.g. rolling elements made of non-conductive material, e.g. glass) can be used.
Die erfindungsgemäß hergestellte drehbare Verbindung iSt weiters korrosionabeständig. Die Korrosionsbeständigkeit wird hiebei ohne besonderen Kostenaufwand erzielt, da hiezu lediglich die Wälzkörper und die Ringe aus korrosionsbeständigem Material, insbes. säurefestem Stahl, bestehen müssen. Die Drahtkosten für die Herstellung der Ringe fallen in keiner Weise ins Gewicht. The rotatable connection produced according to the invention is furthermore corrosion resistant. The corrosion resistance is achieved without any special expense achieved, because for this purpose only the rolling elements and the rings made of corrosion-resistant Material, especially acid-proof steel. The cost of the wire to make the rings do not matter in any way.
Weiters sind erfindungsgemäß hergestellte Lagerungen in gewissen Grenzen gegen Schräglauf (der bei nicht fluchtenden Achsen der drehbar miteinander verbundenen Teile eintritt) unempfindlich. Erfindungsgemäß hergestellte Lagerungen sind in beliebigen Abmessungen, insbes. Miniaturabmessungen, herstellbar. Furthermore, bearings produced according to the invention are in certain Limits against skew (that of axes that are not aligned with one another and that can be rotated with one another connected parts occurs) insensitive. Bearings produced according to the invention can be produced in any dimensions, especially miniature dimensions.
Ein nach dem erfindungsgemäßen Verfahren herstellbarer Gegenstand wird an Hand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung veranschaulicht hiebei eine erfindungsgemäß hergestellte drehbare Verbindung in einem Achsschnitt. An article that can be produced by the method according to the invention is explained in more detail with reference to an embodiment shown in the drawing. The drawing illustrates hiebei a rotatable manufactured according to the invention Connection in one axial section.
In dem Ausführungsbeispiel ist angegeben, daß die beiden zu verbindenden Bauteile 1, 2 aus Kunststoff bestehen. In den Bauteilen 1 und 2 sind hiebei parallel zueinander jeweils zwei Ringe 3, die aus Stahldraht bestehen, eingebettet. Die Einbettung erfolgt gleichzeitig mit dem Spritzen der Bauteile 1 und 2. Die Wälzkörper 4 liegen an den Ringen 3 an. Der Korb zur Distanzierung der Wälzkörper 4 ist in der Zeichnung nicht dargestellt. In the embodiment it is indicated that the two to be connected Components 1, 2 are made of plastic. In the components 1 and 2 are parallel to each other two rings 3, which are made of steel wire, embedded. The embedding takes place at the same time as the injection molding of components 1 and 2. The rolling elements 4 are located on the rings 3. The basket for spacing the rolling elements 4 is shown in the drawing not shown.
