Description
Die Erfindung betrifft eine weitere Ausbildung des Elektromotors mit am Läufer angeordneten Werkzeugen zum Schleifen, Polieren oder anderweitigen Bearbeiten von Außenzylinderflächen, insbesondere an Kurbelzapfen, nach Patent 537 177. Nach diesem Patent sind die Werkzeuge an der Innenseite des in an sich bekannter Weise hohl ausgeführten Läufers, dessen Achse konzentrisch zur Werkstückachse umläuft, untergebracht, derart, so daß sie das im axialen Kanal des Läufers liegende Werkstück gleichzeitig berühren. Dabei können der Läufer und das in seinem axialen Kanal untergebrachte Werkstück zur Erhöhung der Schleifgeschwindigkeit natürlich auch in entgegengesetzten Richtungen umlaufen. Statt nun den Läufer zentrisch anzuordnen, wird er gemäß vorliegender Erfindung exzentrisch gelagert. Dadurch wird die an sich bekannte den Grobschliff fördernde Wirkung erreicht, daß die einzelnen Schneiden usw. der Schleifkörner in den Schleifbacken stetig in das Werkstückmaterial ein- und wieder austreten und sichelförmige Späne herausschneiden, die leicht abgeführt werden im Gegensatz zu den zentrisch umlaufenden Schneidbacken, wo die Schneiden einmal eingetreten, im Werkstückmaterial verbleiben, die (Grob-) Schleifwirkung also infolge schlechter Späneabfuhr beeinträchtigt wird. Auf diese Weise können auch stärkere Späne von der Werkstückfläche abgenommen werden als bei konzentrischem Werkzeugumlauf.The invention relates to a further development of the electric motor with tools arranged on the rotor for grinding, polishing or other processing of Outer cylinder surfaces, in particular on crank pins, according to patent 537 177. According to this Patent are the tools on the inside of the hollow in a known manner Runner, the axis of which rotates concentrically to the workpiece axis, housed, so that it is in the axial channel of the Touch the workpiece that is lying on the carriage at the same time. The runner and the in workpiece placed in its axial channel to increase the grinding speed of course also run in opposite directions. Instead of now the runner to be arranged centrally, it is mounted eccentrically according to the present invention. Through this the known effect of coarse grinding is achieved that the individual cutting edges etc. of the abrasive grains in the grinding jaws steadily enter and exit the workpiece material and become sickle-shaped Cut out chips that are easily removed in contrast to the centric ones circumferential cutting jaws, where the cutting edge has entered once, in the workpiece material remain, so the (coarse) grinding effect is impaired as a result of poor chip removal will. In this way, even thicker chips can be removed from the workpiece surface can be reduced than with concentric tool circulation.
Auf der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise veranschaulicht. In the drawing, the invention is illustrated in one embodiment, for example.
Wie im Hauptpatent beschrieben, handelt es sich um einen Elektromotor, dessen Ständer ι bei 2 ein- oder mehrfach geteilt ist, während der hohle Läufer 3, an dessen Innenseite die Werkzeuge 5 radial angebracht sind, ohne Welle im Ständer 1 auf Gleitringen, Kugellagern o. dgl. gelagert oder geführt ist. Das zylindrische Werkstück 6 ist, wie an sich bekannt, exzentrisch in der Läuferbohrung gelagert,' wobei es, wie durch die Pfeile angedeutet, zweckmäßig im entgegengesetzten Sinne wie der Läufer selbst umläuft. Damit der Läufer 3 um das Werkstück 8 herumgelegt werden kann, kann er selbst bei 7, ähnlich wie der Ständer 1, ein- oder mehrfach- · geteilt sein. Die Anzahl und Art der auf der Innenseite des Läufers 4 sitzenden Werkzeuge 5 ist beliebig. ■■■As described in the main patent, it is an electric motor whose stator ι is divided one or more times at 2, while the hollow rotor 3, on the inside the tools 5 are attached radially, without a shaft in the stand 1 on slide rings, Ball bearings or the like. Is stored or guided. The cylindrical workpiece 6 is, as in itself known, eccentrically mounted in the rotor bore, 'where, as indicated by the arrows, expedient in the opposite sense as the runner itself rotates. So that the rotor 3 is placed around the workpiece 8 can be, it can even at 7, similar to the stand 1, one or more times be divided. The number and type of tools sitting on the inside of the rotor 4 5 is arbitrary. ■■■
Die Erfindung kann nicht nur bei dem Elektromotor nach dem Hauptpatent, sondern auch bei der auf demselben Prinzip beruhenden Turbine nach Patent 532 732 zur Anwendung gelangen.The invention can not only with the electric motor according to the main patent, but also used in the turbine according to patent 532 732, which is based on the same principle reach.
