Abstract

In order to obtain a constant torque during the rotary phase in axial piston machines, in order to be able to operate these, in particular, as an engine at extremely low speeds and as a constant delivery pump, the disc cam, instead of the usual plane set at an angle (swashplate), comprises one or more uniform section(s) of a screw helical surface with lefthand and righthand pitch and the axis of the piston drum is identical to the axis of this surface. At the same time the pistons are supported on the helical surface by way of bearings fitted at their end and thus produce a torque which remains constant throughout the rotary phase.

Description

Langsamlaufende Axialkolbenmaschine mit fast absolutemSlow running axial piston machine with almost absolute

Rundlauf Die Erfindung betrifft eine langsamlaufende Axialkolbenmaschine mit fast absolutem Rundlauf.Concentricity The invention relates to a slow-running axial piston machine with almost absolute concentricity.

Axialkolbenmaschinen mit in einer Kolbentrommel axial beweglichen Kolben sind in vielen Variationen bekannt, doch haben sie alle gemeinsam, daß, wenn niedrige Drehzahlen gewünscht sind, sie infolge ihres meist sinusförmigen Momentverlaufs der Drehphase, entweder nur in höheren Drehzahlen mit nachgeschalteten Getrieben oder in niedrigen nur mit mehreren Zylindern ausgestattet, betrieben werden können, was die Betriebssicherheit und den Wirkungsgrad senkt und zu aufwendigerer Bauweise führt.Axial piston machines with axially movable in a piston drum Pistons are known in many variations, but they all have in common that, when low speeds are desired, because of their mostly sinusoidal torque curve the rotational phase, either only at higher speeds with downstream gears or in low only equipped with several cylinders, can be operated, which lowers operational safety and efficiency and leads to a more complex construction leads.

Aufgabe der Erfindung ist, dieses Problem durch eine langsamlaufende Axialkolbenmaschine mit konstantem Drehmoment während der Drehphase, zu lösen.The object of the invention is to solve this problem by a slow Axial piston machine with constant torque during the turning phase, to be solved.

Die Lösung besteht erfindungsgemäß darin, daß die Steuerscheibe anstatt wie üblich aus einer schräggestellten Ebene (Taumelscheibe), aus einem, oder mehreren gleichförmigen links- und rechtsgängig steigenden Abschnitt(en) einer Schrauben-Wendelfläche besteht, die Achse der Kolbentrommel gleich Achse dieser Fläche ist, und die Kolben sich über an ihrem Ende angebrachte Lager auf der Wendel fläche abstützen.The solution according to the invention is that the control disk instead as usual from an inclined plane (swash plate), from one or more uniform left-hand and right-hand rising section (s) of a helical screw surface consists, the axis of the piston drum is equal to the axis of this surface, and the pistons be supported on the helical surface via bearings attached to its end.

Die Wirkung davon ist, daß der Drehmoment während der Drehphase konstant bleibt, und, bei Betrieb als Pumpe, der Förderstrom gleichmäßig ist.The effect of this is that the torque is constant during the turning phase remains, and, when operated as a pump, the flow rate is uniform.

Die Zeichnungen (Fig. 1 u.2) stellen zwei Längsschnitte einer Ausführungsform der Maschine dar.The drawings (Fig. 1 and 2) represent two longitudinal sections of an embodiment of the machine.
