Description
Vorrichtungen zu dem Zweck, zwischen in einem Antrieb liegenden starren Wellen ohne Beeinflussung der Drehzahlen dieser Wellen eine Lageänderung herbeizuführen, sind - z. B. in Anwendung bei Schleifmaschinen mit verschwenkbaren Schleifelementen - an sich bekannt. Bei dem Antrieb gemäß der Erfindung laufen bei Verdrehung eines Doppelkegelradumlaufgetriebes um eine zur Antriebswelle senkrechte Achse die getriebenen Wellen mit zwei verschiedenen Drehzahlen um, deren Summe gleich der Summe der beiden Drehzahlen der Abtriebswellen bei nicht erfolgender Verdrehung um die Schwenkachse ist. Analog verhalten sich auch die an den Kegelrädern angreifenden und von den eingeleiteten Drehmomenten herrührenden Umfangskräfte. Somit kann durch die Anordnung gemäß der Erfindung eine Lageänderung eines Kegelradumlaufgetriebes erreicht werden, ohne daß die Summe der Drehzahlen der getriebenen Wellenstränge bzw. die an den Umfängen dieser Getriebeelemente angreifenden Umfangskräfte während erfolgender Verdrehung beeinflußt werden.Devices for the purpose of rigid between lying in a drive Cause shafts to change their position without influencing the speed of these shafts, are - z. B. in use in grinding machines with pivotable grinding elements - known per se. In the drive according to the invention, one run when it is rotated Double-bevel epicyclic gearbox that is driven around an axis perpendicular to the drive shaft Shafts with two different speeds around, the sum of which equals the sum of the two Speeds of the output shafts when there is no rotation about the swivel axis is. Those acting on the bevel gears and from the behave analogously induced torques resulting from circumferential forces. Thus, by the arrangement according to the invention, a change in position of a bevel gear can be achieved, without the sum of the speeds of the driven shafts or those of the Circumferences of these gear elements applied circumferential forces during Twist can be influenced.
Die Zeichnung zeigt eine Draufsicht der der Erfindung zugrunde liegenden Vorrichtung.The drawing shows a plan view of the one on which the invention is based Contraption.
Die mit den doppelt ausgebildeten Umlaufrädern 4, 5 des von der Motorwelle 7 angetriebenen Kegelradumlaufgetriebes 4, 6, 5 kämmenden Kegelräder 2, 3 drehen die zu verschwenkenden Abtriebswellen Ia, Ib, und zwar wenn die Umlaufräder 4, 5 und die Kegelräder 2; 3 gleich groß sind gleich schnell, auf Grund der konstruktiven Ausbildung des Kegelradumlaufgetriebes auch in gleicher Richtung.The with the double formed planet gears 4, 5 of the motor shaft 7 driven bevel gear 4, 6, 5 meshing bevel gears 2, 3 rotate the output shafts Ia, Ib to be pivoted, namely when the planetary gears 4, 5 and the bevel gears 2; 3 of the same size are the same speed, due to the constructive Training of the epicyclic bevel gear also in the same direction.
Die ebenfalls in gleicher Richtung und gleich schnell erfolgende Verschwenkung der Abtriebswellen Ia, Ib wird vermittels Drehung des Rades II und dadurch der in den Naben der Umlaufräder 4, 5 drehbar gelagerten Welle Io bewirkt, wobei deren in entsprechende Hohlräume der Wellen Ia, Ib eingeführten Seitenarme 8, 9 die Wellen Ia, Ib mit den Kegelrädern 2, 3 über die Umlaufräder 4, 5, bei bleibendem Zahneingriff der Kegelräder 2, 3 mit den Umlaufrädern 4, 5, verschwenken.The pivoting, which also takes place in the same direction and at the same speed of the output shafts Ia, Ib is activated by rotating the wheel II and thereby the in causes the hubs of the planetary gears 4, 5 rotatably mounted shaft Io, the Side arms 8, 9 introduced into corresponding cavities of the shafts Ia, Ib are the shafts Ia, Ib with the bevel gears 2, 3 via the planetary gears 4, 5, with permanent meshing the bevel gears 2, 3 with the planet gears 4, 5, pivot.
Da die Wellen Ia, Ib mit den Kegelrädern 2, 3 sich in gleichen, die Umlaufräder 4, 5 sich jedoch in entgegengesetzten Richtungen drehen, so wird bei gleichzeitiger Verdrehung der gesamten Getriebeanordnung um die Achse der Welle Io die Drehzahl der einen der beiden Wellen Ia, Ib vergrößert und die der anderen verkleinert. Infolge der obererwähnten Größenverhältnisse der Kegelräder 2, 3, 4 5 sind diese Drehzahlveränderungen im Maß jedoch gleich, so daß sie einander kompensieren, mit der Folge, daß die Summe der an den Wellen Ia, Ib angreifenden Umfangskräfte bei der Verschwenkung dieser Wellen nicht verändert wird.Since the shafts Ia, Ib with the bevel gears 2, 3 are identical, the Planetary gears 4, 5, however, rotate in opposite directions simultaneous rotation of the entire gear assembly around the axis of the shaft Io increases the speed of one of the two shafts Ia, Ib and that of the other scaled down. As a result of the aforementioned proportions of the bevel gears 2, 3, 4 5, however, these speed changes are the same, so that they compensate for each other, with the result that the sum of the circumferential forces acting on shafts Ia, Ib is not changed when these shafts are pivoted.
Die Lagerung der ganzen Vorrichtung erfolgt zweckmäßigerweise in einem zylindrischen, in seinem oberen und unteren Teil um die Achse der Welle Io drehbaren Gehäuse.The entire device is expediently stored in one cylindrical, rotatable in its upper and lower part about the axis of the shaft Io Casing.
