Langjs ami auf ende Radialkolbenmaschine mit fast absolutem Rundlauf Langjs ami on the end of the wheel piston machine with almost absolute concentricity
Die Erfindung betrifft eine langsamlaufende Radialkoiben maschine mit fast absolutem Rundlauf.The invention relates to a slow-running Radialkoiben machine with almost absolute concentricity.
Radialkolbenmaschinen sind in vielen Variationen bekannt,doch haben sie alle gemeinsam,daß,wenn niedrige Drehzahlen gewünscht sind,sie infolge ihres meistens unsymmetrischen Momentverlaufs der Drehphase,entweder nur in höheren Drehzahlen mit nachge schalteten Getrieben oder in niedrigen nur mit mehreren Zylindern ausgestattet,betrieben werden können,was die Betiebs sicherheit und den Wirkungsgrad senkt und zu aufweniger Bauweise führt.Radial piston machines are known in many variations, however they all have in common that when low speeds are desired they are due to their mostly asymmetrical moment curve the rotational phase, either only at higher speeds with downstream Geared or in low only equipped with several cylinders, can be operated, which the operational safety and reduces the efficiency and leads to less construction.

Langsamiaufende Radialkolbenmaschine mit fast absolutem RundlaüfSlow running radial piston machine with almost absolute Roundness
Um bei Radialkolbenmaschinen einen konstanten Drehmoment während der Drehphase zu erhalten,um diese insbesondere als Antriebsmaschine in extrem niedrigen Drehzahlen betreiben zu können,besteht bei Maschinen mit in kreisenden Zylindern radial beweglichen Kolben die innea?e Form des Querschnitts des Stators,und bei Maschinen mit in zum rotierendem Exzenter radial angeordneten Zylindern beweglichen Kolben der Querschnitt des Exzenters,aus einem,oder mehreren gleichförmigen Abschnitt(en) einer archimedischen Spirale, und ist die Drehachse des Rotors/Exzenters gleich Achse dieser Spirale.Die Kolben stützen sich dabei über an ihrem Ende angebrachte Lager bei Druckbeaufschlagung der Zylinder an der Statorinnenwand/Exzenteraußenwand ab,und erzeugen dadurch den Drehmoment,der während der Drehphase,bei gleichbleibendem Druck des Arbeitsmediums,konstant bleibt.In order to obtain a constant torque during the rotary phase in radial piston machines, in order to use this in particular as To be able to operate the prime mover at extremely low speeds is the case with machines with rotating cylinders radially movable piston takes the inner shape of the cross section of the stator, and in machines with in for rotating Eccentric cylinders arranged radially movable piston of the cross section of the eccentric, from one, or more uniform section (s) of an Archimedean spiral, and the axis of rotation of the rotor / eccentric is the same as the axis The pistons are supported by bearings attached to their ends when the cylinders are pressurized on the stator inner wall / eccentric outer wall, and thereby generate the torque that occurs during the rotation phase constant pressure of the working medium, remains constant.
