Description

Werkzeugmaschine, insbesondere Schleifmaschine, zur Herstellung von durch zykloidische Kurven begrenzten Querschnitten an Außen- und Innenprofilen Das Zusatzpatent 7iö o67 unterscheidet sich von dem Ausführungsbeispiel des Hauptpatents 708 743 dadurch, daß, unter Beibehaltung der Eigenbewegungen von Werkzeugträger und Werkstückträger, die periodisch beschleunigte und verzögerte Drehbewegung des Werkstückträgers getrennt erzeugt wird, d. h. derjenige Getriebeteil, welcher die dem Werkstückträger zukommende Drehbewegung hervorruft, ist von der Getriebeeinheit des Hauptpatents abgesondert worden.Machine tool, in particular grinding machine, for the production of cross-sections on outer and inner profiles limited by cycloidal curves.The additional patent 7iö o67 differs from the embodiment of the main patent 708 743 in that, while maintaining the own movements of the tool carrier and workpiece carrier, the periodically accelerated and decelerated rotary movement of the workpiece carrier is generated separately, ie that gear part which causes the rotational movement of the workpiece carrier has been separated from the gear unit of the main patent.

Die vorliegende zweite Zusatzerfindung macht sich nun die auch unter dem Namen elektrische Welle bekannte Anordnung von je zwei Gleich- und zwei Drehstrommotoren mit einer Schaltung zur Sicherung des Gleich-Laufes zweier Wellen zunutze, um die sonst bei der in Betracht kommenden Unrundprofilschleifmaschine in größerer Zahl benötigten Stirn- und Kegelräder zu ersparen und dadurch eine beachtliche Fehlerquelle für die Genauigkeit der herzustellenden Unrundprofile auszuschließen.The present second auxiliary invention now makes use of the electrical also called shaft known arrangement of two DC and two AC motors with a circuit for securing the DC-passage of two shafts advantage required to would otherwise in the eligible non-circular profile grinding machine in greater numbers To save spur and bevel gears and thereby exclude a considerable source of error for the accuracy of the non-circular profiles to be produced.

Die Zusatzerfindung besteht im wesentlichen darin, daß ein Motorenpaar die eine Hubwelle antreibt, welche .die Eigen@bew.egung des Werkzeugträgers (Schleifbockes) erzeugt, während ein zweites Motorenpaar, das mit dem ersten Motorenpaar in bekannter Weise elektrisch gleichlaufend geschaltet ist, die andere Hubwelle antreibt, deren Exzenter über eine Kulisse .das Planetengetriebe steuert, dessen Bewegung über Stirnräder auf die Werkstückspindel übertragen wird.The additional invention consists essentially in the fact that a pair of motors which drives a lifting shaft, which. the own movement of the tool carrier (bench grinder) generated while a second pair of motors, which is known with the first pair of motors Way is electrically connected in parallel, which drives the other lifting shaft, whose Eccentric via a backdrop. The planetary gear controls its movement via spur gears is transferred to the workpiece spindle.

Durch den Fortfall zahlreicher Stirn- und Kegelräder,. deren Teilgenauigkeit und Spielausgleich die Güte der zu erzeugenden Profile maßgebend beeinflussen; ergibt sich eine Unrundprofilschleifmaschine, die eine denkbar hohe Genauigkeit verbürgt, was bei solchen Maschinen deshalb von entscheidender Bedeutung ist, weil jede selbst verhältnismäßig kleine Ungenauigkeit die bearbeiteten Werkstücke unbrauchbar macht, besonders wenn es sich um die Herstellung sogenannter Zapfenlochverbindungen handelt.By eliminating numerous spur and bevel gears. their indexing accuracy and backlash compensation have a decisive influence on the quality of the profiles to be generated; results a non-circular profile grinding machine, which has a very high level of accuracy guarantees, which is of crucial importance with such machines because any even relatively small inaccuracy makes the machined workpieces unusable especially when it comes to the production of so-called mortise and tenon joints acts.

Auf der Zeichnung ist die Er$ndung in schematischer Darstelung beispielweise veranschaulicht.The invention is shown schematically in the drawing, for example illustrated.

Wie bei dem Zusatzpatent 710 o67 sind die für die Erzeugung der Eigenbewegungen des Werkzeugträgers und .des Werkstückträgers erforderlichen Getriebeteile in zwei räumlich getrennten. Hub- bzw. Exz.enterwellen untergebracht. Durch das eine Motorenpaar 111, M2 wird die Hubwelle Hl angetrieben, die in bekannter Weise die Eigenbewegung des Schleifbockes erzeugt. Diese Eigenbewegung verläuft nach einer ellipsenähnlichen Bahn, wenn es sich um die Herstellung von zykloidenförmigen, dreieckartigen Außen-bzw. Innenprofilen handelt. Das zweite Motorenpaar 1173, 1T4 ist, wie an sich bekannt, mit dem ersten Motorenpaar 11i11, 1172 elektrisch gleichlaufend geschaltet und treibt die Hubwelle HZ an. Der Exzenter 3, der Hubwelle H, steuert über die Kulisse h: das wie bei dem@Zusatzpatent 71o o67 zur Werkstückspindel W gelegte Planetengetriebe, F. Durch ein Stirnradpaar R1, R= wird die Bewegung des Planetengetriebes P auf die Werkstück-Spindel W übertragen, die dadurch eine periodisch beschleunigte und verzögerte Drehbewegung ausführt.As with the additional patent 710 067, they are for the generation of the own movements the tool carrier and .the workpiece carrier required gear parts in two spatially separated. Hub or eccentric shaft housed. Through the one pair of motors 111, M2, the lifting shaft Hl is driven, which, in a known manner, has its own movement generated by the bench grinder. This proper movement follows an ellipse-like one Railway when it comes to the production of cycloidal, triangular external or. Internal profiles. The second pair of motors 1173, 1T4 is, as is known per se, electrically synchronized with the first pair of motors 11i11, 1172 and drives the lifting shaft HZ. The eccentric 3, the lifting shaft H, controls via the gate h: the planetary gear set as in the @ additional patent 71o o67 to the workpiece spindle W, F. By a pair of spur gears R1, R = the movement of the planetary gear P is on the Transferred workpiece spindle W, which thereby periodically accelerated and decelerated Rotary movement executes.
