Aus der
DARSTELLUNG DER ERFINDUNGPRESENTATION THE INVENTION
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Schieber-Rotorkragen-Ausbildung anzugeben, die eine gute Dichtflächenkonstruktion beinhaltet und die wirtschaftlich einfach hergestellt werden kann.Based on this state of the art the invention has for its object a slide rotor collar training to indicate the good sealing surface construction includes and which can be manufactured economically simple.
Die erfindungsgemäßen Dichtungsflächen sind durch die Merkmale des Anspruchs 1 gegeben. Eine Vorrichtung zum Herstellen der die Dichtungsflächen des Schiebers darstellenden Laibungsflächen des im Schieber vorhandenen Durchbruches ist durch die Merkmale des Anspruchs 2 angegeben. Weiterbildungen einer solchen Vorrichtung sind Gegenstand von sich an den Anspruch 2 anschließenden weiteren Ansprüchen.The sealing surfaces according to the invention are given by the features of claim 1. A device for Making the sealing surfaces the soffit surfaces representing the slider of the existing in the slider Breakthrough is indicated by the features of claim 2. further developments such a device are the subject of the claim 2 subsequent further claims.
Die erfindungsgemäßen Dichtungsflächen beinhalten, dass der polygonartige, insbesondere rechteckförmige Querschnitt des Rotorkragens ausgerundete Eckbereiche besitzt. Ferner besitzen die Laibungswände des im Schieber vorhandenen Durchbruches ausgerundete Stoßkanten derart, dass der Rotorkragen bei seiner Rotationsbewegung auch mit seinen ausgerundeten Eckbereichen an den Laibungswänden des Durchbruches dichtend anliegt.The sealing surfaces according to the invention include that the polygonal, in particular rectangular cross section of the rotor collar has rounded corner areas. Furthermore, the reveal walls of Rounded edges in the opening of the slide such that the rotor collar also rotates during its rotational movement its rounded corner areas on the reveal walls of the Breakthrough sealing.
Durch die Ausrundungen wird erreicht, dass sich mögliche Abnützungen druckmäßig nicht so stark negativ auswirken, als es bei mehr oder weniger winklig aneinanderstoßenden Kanten beziehungsweise Ecken in den Laibungswänden des Schieberdurchbruches der Fall ist. Der Schieber als ein Verschleißteil ist aus relativ weichem Material hergestellt, so dass die Laibungswände ihre dichtende Anlage am Rotorkragen relativ schnell verlieren können. Die Standzeit des Schiebers hängt ab von den Bedingungen, mit denen die entsprechende Pumpe betrieben wird. Außerdem stellt die im Übergang zwischen dem Rotorkragen und der Rotornabe vorhandene Ausrundung eine umfangsmäßig vergrößerte Umfangslinie des Rotorkragens dar, was eine entsprechend vergrößerte Kontaktfläche zwischen dem Rotorkragen und den Laibungsflächen im Schieberdurchbruch ermöglicht. Allerdings werden die Laibungsflächen, die dieser Ausrundung des Rotorkragens entsprechende Auswölbungen aufweisen müssen, in ihrer Oberflächenkontur derart kompliziert, dass sie sich nur mit größtem Aufwand auf rechnergestützten Fräsmaschinen herstellen lassen. Erfindungsgemäß ist daher vorgesehen, den im Schieber vorhandenen schlitzartigen Durchbruch mittels einer Kopierfräsmaschine herzustellen.The fillets achieve that possible Abnützungen not in terms of pressure negative impact as much as it is at more or less angular abutting Edges or corners in the reveal walls of the slide opening the case is. The slider as a wearing part is made of relatively soft Material made so that the soffit walls on their sealing system Can lose rotor collar relatively quickly. The service life of the slide depends of the conditions with which the corresponding pump is operated becomes. Moreover puts the in transition Rounding existing between the rotor collar and the rotor hub a circumferentially enlarged circumferential line of the rotor collar, which is a correspondingly enlarged contact area between the Rotor collar and soffit areas enabled in the gate opening. However, the soffit areas, the bulges corresponding to this rounding of the rotor collar must have in their surface contour so complicated that it can only be done with great effort on computer-assisted milling machines have it made. According to the invention provided the slit-like breakthrough existing in the slide using a copy milling machine manufacture.
Wie ein in der Zeichnung dargestelltes Ausführungsbeispiel für eine solche Kopierfräsmaschine verdeutlicht, kann ein dem Querschnitt des Rotorkragens entsprechendes Rotationsfräswerkzeug um eine erste Achse drehbar angeordnet werden. Ein dem Schieber bis auf den Durchbruch entsprechendes Werkstück wird dann an einem Schlitten befestigt. Der Schlitten und das Rotationswerkzeug sind einerseits relativ zueinander verstellbar in einer zur Drehachse des Rotorfräswerkzeuges senkrechten Querrichtung. Ferner sind der Schlitten und das Rotationsfräswerkzeug auch in einer zu dieser Drehrichtung parallelen Längsrichtung relativ zueinander verstellbar.As an exemplary embodiment of such a copy milling machine shown in the drawing illustrates, a rotary milling tool corresponding to the cross section of the rotor collar can be arranged rotatably about a first axis. A workpiece corresponding to the slide except for the opening is then attached to a slide. The carriage and the rotary tool are on the one hand adjustable relative to one another in a transverse direction perpendicular to the axis of rotation of the rotor milling tool. Furthermore, the slide and the rotary milling tool are also in the same direction as this direction parallel longitudinal direction adjustable relative to each other.
Eine Verstellung des das jeweilige Werkstück tragenden Schlittens in seiner Längsrichtung kann durch eine an der Drehachse drehfest befestigte, der Kontur des Rotorkragens angepasste Steuerscheibe bewirkt werden. Diese Steuerscheibe liegt dann in beiden Längsrichtungen und damit in beiden Verstellrichtungen des Schlittens jeweils schubfest an demselben an.An adjustment of the respective workpiece supporting carriage in its longitudinal direction by a non-rotatably attached to the axis of rotation, the contour of the Adjusted rotor collar control disc can be effected. This control disc then lies in both longitudinal directions and thus in both directions of adjustment of the slide in each case resistant to shear the same.
Diese schubfeste Anlage der Steuerscheibe an dem Schlitten kann durch einen Schlitz in dem Schlitten verwirklicht werden, in den die Steuerscheibe in Querrichtung eintauchen kann beziehungsweise zumindest geringfügig fortwährend eintaucht.This thrust-resistant system of the control disc the carriage can be realized through a slot in the carriage in which the control disc can dip in the transverse direction or at least slightly submerged.
Weitere Vorteile und Merkmale der Erfindung sind den in den Ansprüchen ferner angegebenen Merkmalen sowie dem nachstehenden Ausführungsbeispiel zu entnehmen.Other advantages and features of Invention are those in the claims further specified features and the following embodiment refer to.
