Description

Es ist schon bekannt, Werkzeugmaschinen durch Flüssigkeitsgetriebe anzutreiben, die an Stelle der Rädervorgelege treten und die Erzeugung jeder beliebigen Geschwindigkeit ermöglichen sollen. Bei der bisher bekannten Anordnung waren die Pumpe und der Motor durch eine Rohrleitung verbunden, die durch den Spindelkasten hindurchgeführt wurde. Diese Anordnung eignete sich daher nur für Werkzeugmaschinen, welche keine durchgehende Welle besaßen, sondern bei denen das Arbeitsstück von der Seite her in die Maschine eingelegt wurde, wie das beispielsweise bei Drehbänken mit Planscheibe geschieht, igIt is already known to drive machine tools by means of fluid gears that are connected to Step in place of the gear reduction and enable the generation of any desired speed should. In the previously known arrangement, the pump and the motor were connected by a pipe that ran through the headstock was passed through. This arrangement was therefore only suitable for Machine tools which did not have a continuous shaft, but in which the workpiece was inserted from the side into the Machine has been inserted, as is the case, for example, with lathes with face plates, ig

Durch die vorliegende Erfindung soll die Einführung des Ölantriebes bei Werkzeugmaschinen ermöglicht werden, die durchgehendes Stangenmaterial verarbeiten, wie Automaten und Revolverbänke. Gerade für diese ist die Anwendung eines Ölgetriebes sehr wichtig, weil es hier darauf ankommt, die Geschwindigkeit sehr fein und in großen Grenzen abzustufen. Bisher sind Revolverdrehbänke mit hydraulischem Antrieb noch nicht gebaut.The present invention is intended to introduce the oil drive in machine tools that process continuous bar material, such as machines and turret benches. Especially for this is the use of an oil gear very important because it depends on the speed very fine and graduated within large limits. Turret lathes with hydraulic drives have not yet been built.

Gemäß der Erfindung wird das Ölgetriebe,According to the invention, the oil transmission,

bei dem beispielsweise Pumpe und Motor in derselben Achse sitzen, neben der Hauptwelle im Spindelstock angeordnet) und zwar so, daß die Hauptwelle frei durch den Spindelstock hindurchgeht. Es kann infolgedessen diese Welle hohl ausgeführt werden. Der Durchmesser ist unabhängig von der Art und der Ausbildung des Ölgetriebes. Da zwischen hydraulischem Motor und Hauptwelle ein einfaches Zahnrädervorgelege eingeschaltet werden muß, so kann man Pumpe und Ölmotor unmittelbar neben der Hauptwelle anordnen, so daß diese Teile keinen erheblichen Platz beanspruchen.
Auf der Zeichnung stellt
in which, for example, the pump and motor sit in the same axis, arranged next to the main shaft in the headstock) in such a way that the main shaft passes freely through the headstock. As a result, this shaft can be made hollow. The diameter is independent of the type and design of the oil gear. Since a simple gear reducer has to be switched on between the hydraulic motor and the main shaft, the pump and oil motor can be arranged directly next to the main shaft so that these parts do not take up any significant space.

Das Ölgetriebe besteht aus der Pumpe α und dem Motor b. Pumpe und Motor sind gleichartig ausgebildet. Sie bestehen beispielsweise in einer umlaufenden Scheibe c, in welcher Zylinder ausgespart sind, deren Kolben durch in ihrer Exzentrizität zu verstellenden Führung^ verschoben werden. Der Antrieb der Pumpe α erfolgt von der Riemenscheibe /. Der Motor überträgt die Bewegung auf das Ritzel g·, das in das Zahnrad h auf der Hauptwelle k der Werkzeugmaschine, beispielsweise in der Leitspindeldrehbank, eingreift. Die Welle k ist durch das Gehäuse / des Antriebes hinduTchgeführt, sie kann daher beispielsweise hohl sein, so daß der Durchführung von Stangenmaterial nichts im Wege steht.The oil gear consists of the pump α and the motor b. The pump and motor are designed in the same way. They consist, for example, of a rotating disc c in which cylinders are recessed, the pistons of which are displaced by guides which can be adjusted in their eccentricity. The pump α is driven by the pulley /. The motor transmits the movement to the pinion g · which meshes with the gear wheel h on the main shaft k of the machine tool, for example in the lead screw lathe. The shaft k is guided through the housing / drive, it can therefore be hollow, for example, so that nothing stands in the way of rod material being passed through.
