Description
Ölmotor in Radialkolbenbauart Ölrnotoren in Radialkolbenbauart mit vorzugsweise feststehend-er Polkurve, welche als Vieleck mit abgerundeten Ecken ausgebildet ist, sind bekannt. Die Polkurven lassen je Umdrehung zwei oder mehr Kolbenhübe zu. Die Vardrängerwalze dreht sich um einen feststehenden Steuerzapfen, der mit einer Bohrung versehen ist, welche die Durchführung einer @Velle gestattet.Oil motor in radial piston design Oil motors in radial piston design with preferably fixed-er polar curve, which is a polygon with rounded corners is formed are known. The polar curves leave two or more per revolution Piston strokes closed. The front roller rotates around a fixed control pin, which is provided with a hole, which allows the implementation of a @Velle.
Bei sollchen 0l:motoren ist es bekannt, die Umwandlung der rotierenden Bewegung in eine hin- und hergehende Bewegung vorzunehmen, wofür aufwendige Maschinenelemente, wie eine Zwischenwelle, eine Spindel mit Mutter und entsprechende Lager, erforderlich sind. Die Baulänge ist hierfür sehr groß.At Sollchen 0l: motors it is known to convert the rotating To make movement in a back and forth movement, for which complex machine elements, such as an intermediate shaft, a spindle with nut and appropriate bearings are. The overall length is very large for this.
Um diesen. Mangel zu beseitigen, wird nach der Erfindung ,g vorgeschlagen, die hin- und hergehende Bewegring der Spindel unmittelbar durch den Ölmotor dadurch zu erzeugen, daß ein Mitnebmer an der Verdrängerwalze als Mutter ausgebildet ist und von einer an der Welle angeordneten Spindel durchlaufen wird., wobei die Längsschübe der Spindel von dem Mitnehmer aufgenommen werden.To this one. To eliminate deficiency, it is proposed according to the invention, g, the reciprocating motion ring of the spindle is directly caused by the oil motor to produce that a Mitnebmer is formed on the displacement roller as a nut and is traversed by a spindle arranged on the shaft., wherein the longitudinal thrusts the spindle can be taken up by the driver.
Bei dieser Anordnung können die Lager verringert werden, und eine kürzere Baulänge kann erreicht werden. Für verschiedene Arbeitsgebiete, z. B. den Antrieb von Anstedlspindeln an Walzwerken und bei Spindielpressen, wird nach der Erfindung die Anwendung,des Ölmotor; in raumsparender Anordnung erst möglich.With this arrangement, the bearings can be reduced, and one shorter overall length can be achieved. For different areas of work, e.g. B. the Drive of Anstedl spindles on rolling mills and spindle presses is after the Invention the application of the oil engine; Only possible in a space-saving arrangement.
In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel in einem Längsschnittdargestellt.In the drawing, the subject matter of the invention is in one embodiment shown in a longitudinal section.
Eine Verdrängerwalze 1, versehen mit der beispielsweise konisch eingesetzten Steuerbüchse 1'. trägt zwei Reihen angeordnete Kolben 7, welche in bekannter Weise über Kolbenbolzen und Stützrollen die Flüssigkeitskräfte auf die Polkurve übertragen, -die im Gehäuse gehalten wird. Im Gehäuse ist der hoble Steuerzapfen 2 gelagert. Der Steuerzapfen 2 ist durchbrochen von den Kanälen 3 und 4, welche aus dem Flüssigkeitsverteiler und -sammler die Druckflüssigkeit in die Zvlin:derräume der Verdrängerwalze 1 leiten bzw. die Druckflüssigkeit aus diesen abfließen lassen.A displacement roller 1, provided with the one used, for example, conically Control sleeve 1 '. carries two rows of pistons 7 arranged in a known manner The fluid forces are transferred to the pole curve via piston pins and support rollers, -which is held in the housing. The planar control pin 2 is mounted in the housing. The control pin 2 is pierced by the channels 3 and 4, which from the liquid distributor and -sammler the hydraulic fluid in the Zvlin: derraum the displacement roller 1 lead or let the hydraulic fluid flow out of these.
Die Erzeugung des Drehmomente: vollzieht sich durch die Form der Polkurve über Kreuzkopfführungen in der Verdrängerwalze 1. Das Drebmomelut wird weitergeleitet durch den Mitnebmer 17. Der Mitnehmer17 ist als Mutter mit Innengewinde ausgebildet und so .gelagert, daß er imstande ist, axiale Kräfte aufzunehmen. Der Mitnehmer 17 wird von einer an der Welle 19 angeordneten Spindel 20 durchlaufen, die ebenfalls den hohlen Steuerzapfen 2 durchläuft und in ihm auch geführt werden kann. Damit wird die Verdrängerwalze 1 des Olmotors mittelbar zur Spiudelmutter. Mit einer derartigen Einrichtung können nicht nur sehr große Hubbewegungen bewältigt, sondern auch eine sehr einfache und raumsparende Bauart für den Antrieb großer Spindeln geschaffen werden.The generation of the torque: takes place through the shape of the polar curve Via crosshead guides in the displacement roller 1. The Drebmomelut is passed on by the driver 17. The driver 17 is designed as a nut with an internal thread and so .beared that it is able to absorb axial forces. The driver 17 is traversed by a spindle 20 arranged on the shaft 19, which also passes through the hollow control pin 2 and can also be guided in it. In order to the displacement roller 1 of the oil motor becomes indirectly the spinning nut. With such a Facility can handle not only very large lifting movements, but also a very simple and space-saving design created for driving large spindles will.
