Abstract

This drive consists of an eccentric drive, on the journal of which a connecting rod is radially-axially mounted. The connecting rod, through an intermediate piece mounted axially-radially in the piston, and a ball bush, leads to a reciprocating and rotary movement of the piston. The piston forms with the ball bush a ball screw with low frictional losses.

Description

Das Objekt dieser Patentanmeldung beinhaltet einen einfa­ chen und billigen Antrieb für Verdrängermaschinen, besonders für Dosierpumpen.The object of this patent application contains a simple Chen and cheap drive for displacement machines, especially for dosing pumps.

Der hin- und hergehender Kolben (6) bekommt durch eine Kugelbuchse (5) und ein Zwischenstück (4) gleichzeitig eine rotierende Bewegung.The reciprocating piston ( 6 ) is simultaneously rotated by a ball bushing ( 5 ) and an intermediate piece ( 4 ).

Bei bekannten Antrieben der genannten Art, bei denen mittels eines zylindrischen Kreuzkopfes, einer Zahnradbuchse in de­ ren Nut eine Feder gleitet, bekommt der Kolben eine Dreh­ bewegung, sind die Reibungsverluste wesentlich zu berück­ sichtigen und die Konstruktionen sind kompliziert.In known drives of the type mentioned, in which means a cylindrical crosshead, a gear bush in de If a tongue slides, the piston will turn movement, the frictional losses are essential and the constructions are complicated.

Die Aufgabe dieser Erfindung besteht demgegenüber darin, Antriebe dieser genannten Art insoweit zu verbessern, durch eine einfache Bauart die auch wesentlich geringere Energie­ verluste aufweist.In contrast, the object of this invention is to To improve drives of this type to the extent that a simple design that also has much lower energy shows losses.

Nach der Erfindung wird diese Aufgabe gelöst mit dem Antrieb nach Anspruch 1.According to the invention, this object is achieved with the drive according to claim 1.

Durch die Erfindung wird auf einfache Weise erreicht, daß der Kolben (6) durch eine Lagerung in eine Kugelbuchse (5) ein Kugelgewindetrieb mit niedrigen Reibungsverlusten bil­ det.By the invention it is easily achieved that the piston ( 6 ) by a bearing in a ball bushing ( 5 ) a ball screw with low friction losses bil det.

In dem Kolben (6) ist ein Zwischenstück (4) axial-radial gelagert, das die Verbindung zwischen Pleuel (3) und Kolben bildet.An intermediate piece ( 4 ) is axially and radially mounted in the piston ( 6 ) and forms the connection between the connecting rod ( 3 ) and the piston.

Der Pleuel (3) ist auf einem Zapfen (2) gelagert.The connecting rod ( 3 ) is mounted on a pin ( 2 ).

Der Zapfen (2) bildet, auf eine einfache Bauweise, zusam­ mengeschweißt mit der glatten Welle (1) ein Exzenterantrieb. Weiter ist es zur Erzielung einer hohen Robustheit und Be­ lastbarkeit des Antriebes zweckmäßig, wenn die Lagerdeckel (7) als Axiallagern ausgebildet sind.The pin ( 2 ) forms, in a simple construction, welded together with the smooth shaft ( 1 ) an eccentric drive. It is also expedient to achieve a high level of robustness and loading capacity of the drive if the bearing cover ( 7 ) is designed as a thrust bearing.

Die Erfindung wird im folgenden anhand eines Ausführungs­ beispiels in Verbindung mit der Zeichnung näher beschrieben.The invention is based on an embodiment example described in connection with the drawing.

Fig. 1 ist eine schematische Querschnitt-Darstellung des Antriebes. Fig. 1 is a schematic cross-sectional representation of the drive.

Fig. 2 ist eine schematische Längsschnitt-Darstellung des Antriebes. Fig. 2 is a schematic longitudinal sectional view of the drive.

Die Figuren zeigen ein Exzenterantrieb (1, 2), der in La­ gerdeckel (7) gelagert ist.The figures show an eccentric drive ( 1, 2 ) which is mounted in the lid ( 7 ).

Auf dem Zapfen (2) ist ein Pleuel (3) radial und axial (auf Lagerdeckeln) oder radial-axial gelagert.A connecting rod ( 3 ) is mounted radially and axially (on bearing caps) or radially-axially on the journal ( 2 ).

Die Hin- und Herbewegung der Pleuel (3) ist durch ein Zwischenstück (4) dem Kolben (6) weiter geleitet.The reciprocating motion of the connecting rods ( 3 ) is passed on to the piston ( 6 ) through an intermediate piece ( 4 ).

Der Kolben (6) bildet mit einer Kugelbuchse (5) ein Kugel­ gewindetrieb, so daß bekommt er gleichzeitig auch eine rotierende Bewegung. Zwischen Pleuel (3) und Kolben (6) befindet sich ein Zwischenstück (4) drehbar in Kolben gelagert.The piston ( 6 ) forms a ball screw drive with a ball bushing ( 5 ), so that it also gets a rotating movement at the same time. Between the connecting rod ( 3 ) and piston ( 6 ) there is an intermediate piece ( 4 ) rotatably mounted in the piston.

Es folgt die Erläuterung der Erfindung anhand der Zeich­ nungen nach Aufbau und ggf. auch nach Wirkungsweise dargestellten Erfindung.There follows the explanation of the invention with reference to the drawing depending on the structure and, if necessary, on the mode of action illustrated invention.
