Abstract
Radialkolbenmaschine,
die eine Welle mit einem Rotor aufweist, in dem Ausnehmungen (2)
zur Aufnahme und Führung
von Kolben (3) angeordnet sind, deren der Welle abgewandte Enden
sich an einer Hubscheibe (6) zur Erzeugung einer radial zur Drehachse
der Welle gerichteten Hubbewegung abstützen und die einen in Richtung
zur Drehachse (A) der Welle verlaufenden Ansatz (10) kleineren Querschnitts
aufweisen, dadurch gekennzeichnet,
dass der Querschnitt jeder
Ausnehmung (2) und der Querschnitt jedes eine Hubbewegung ausführenden
Kolbens (3) ovalförmig
ausgebildet ist,
dass die Großachse des jeweils ovalförmigen Querschnitts parallel
zur Drehachse (A) der Welle verläuft,
dass
der Querschnitt des Ansatzes (10) an dem Kolben (3) rechteckig ist
und
dass die parallel zur Drehachse (A) der Welle verlaufenden Längsseiten
(10a, 10b) des Ansatzes (10) in angepassten Ausnehmungen (12) im
Rotor (1) geführt
sind.Radial piston machine which has a shaft with a rotor, in which recesses (2) for receiving and guiding pistons (3) are arranged, whose ends facing away from the shaft on a lifting disc (6) for generating a radially directed to the axis of rotation of the shaft lifting movement supporting and having a running in the direction of the axis of rotation (A) of the shaft approach (10) of smaller cross-section, characterized
in that the cross-section of each recess (2) and the cross-section of each piston (3) performing a lifting movement are oval-shaped,
that the major axis of each oval-shaped cross-section is parallel to the axis of rotation (A) of the shaft,
that the cross section of the projection (10) on the piston (3) is rectangular and
in that the longitudinal sides (10a, 10b) of the attachment (10) running parallel to the axis of rotation (A) of the shaft are guided in adapted recesses (12) in the rotor (1).
Description
Die Erfindung betrifft eine Radialkolbenmaschine nach dem Oberbegriff des Anspruches 1.The The invention relates to a radial piston machine according to the preamble of claim 1.
Eine
derartige Radialkolbenmaschine mit äußerer Kolbenabstützung ist
beispielsweise durch die
Zur
Erzielung eines hohen Antriebsdrehmomentes sind bei einer Radialkolbenmaschine
mit innerer Kolbenabstützung
mehrere versetzt zueinander angeordnete Kolbenreihen in einem gemeinsamen
Gehäuse
nebeneinander angeordnet. Die Kolben arbeiten mit einer gemeinsamen
mehrere versetzt zueinander angeordnete Exzenter aufweisenden Abtriebswelle
zusammen. (Bauelemente der Hydraulik, Teil 1, S. 209
Aus
der
Die Aufgabe der Erfindung besteht darin, eine Radialkolbenmaschine mit hohem Abtriebsdrehmoment zu schaffen, die gegenüber den herkömmlichen Radialkolbenmaschinen kleinere Gehäuseabmessungen aufweist. Dies wird mit den kennzeichnenden Merkmalen des Patentanspruch 1 erzielt. Durch eine ovale oder oval ähnliche Ausbildung wie z.B. eine Ellipse des Kolbenquerschnittes wird eine vom Arbeitsmittel beaufschlagte Fläche erzielt, die der Fläche von etwa drei Kolben mit kreisförmigem Querschnitt von herkömmlichen Maschinen entspricht. Durch den erfindungsgemäßen Vorschlag werden also in etwa drei nebeneinander liegenden Kolbenreihen durch eine einzige Kolbenreihe ersetzt.The The object of the invention is to provide a radial piston machine high output torque to create, compared to the conventional Radial piston machines has smaller housing dimensions. This is achieved with the characterizing features of claim 1. By an oval or oval like Training such as an ellipse of the piston cross section becomes one of Working medium applied surface scored the area of about three pistons of circular cross-section from conventional Machines corresponds. By the proposal according to the invention are therefore in about three adjacent rows of pistons through a single Replaced piston series.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Patentansprüchen 2 bis 4.Further advantageous embodiments of the invention will become apparent from the claims 2 to 4.
Entsprechend Patentanspruch 2 ist der Kolbenquerschnitt von zwei parallel zur Welle verlaufenden geraden Längsseiten und zwei die Längsseiten verbindenden halbkreisförmigen Schmalseiten gebildet.Corresponding Claim 2 is the piston cross-section of two parallel to Wave extending straight longitudinal sides and two connecting the long sides semicircular Narrow sides formed.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels näher beschrieben.The Invention will be described below with reference to an embodiment.
