Description

Bei gewissen Werkzeugmaschinen mit schnellen Schlittenbewegungen, z. B. Zahnfiankensch,leifmasc'hinen, werden die Schlitten, bei letzteren z. B. der -die Schleifscheibe oder das Werkstück tragende Schlitten, mit verhältnismäßig hoher Geschwindigkeit hin und her bewegt, um in diesem Falle .den zu bearbeitenden Zahn entweder wie bei dem Abwälzverfähren durch eine Summe von Tangenten einzuhüllen oder ihn mit einer Formscheibe fertig zu schleifen. Die Schlittenbewegung wurde hierbei bisher entweder hydraulisch oder auch durch Kurbel- oder Kurvenantrieb bewirkt.On certain machine tools with fast slide movements, z. B. Zahnfiankensch, leifmasc'hinen, the sled, in the latter z. B. the -the grinding wheel or the workpiece-carrying carriage, with relatively high Speed moved back and forth to, in this case, .the tooth to be machined either enveloped by a sum of tangents, as in the rolling process or finish grinding it with a shaped wheel. The sled movement was this has so far been effected either hydraulically or by a crank or cam drive.

Die empfindlichen Zahnffankenschleifmaschinen, die mit 1/100o mm Genauigkeit arbeiten müssen, müssen möglichst vollständig vor Fremd- und Eigenerschütterungen geschützt werden. Die kleinsten Erschütterungen machen sich am Schleifbild. bemerkbar. Bei hydraulischem Antrieb wird in den Wendepunkten ein merkbarer - Stoß empfunden, weil die Umsteuerung plötzlich wirkt. Kurvenbetätigung ist wegen der Unruhe nicht anwendbar., - - Kurbelantriebe mittels Pleuelstange haben den Vorzug eines sanften Richtungswechsels, weil Geschwindigkeitssteigerung und -abfall sinusliniengemäß erfolgen. Aber auch diese sinusartige Geschwindigkeits- und Richtungsänderung . macht sich noch bemerkbar. Versuche, mit Gummizwischenkupplungen die Schwingungen zu dämpfen, führten nur teilweise zum Ziel.The sensitive tooth flank grinding machines with 1 / 100o mm accuracy have to work, must be as completely as possible from external and self-vibrations to be protected. The smallest vibrations affect the sanding pattern. noticeable. With a hydraulic drive, a noticeable shock is felt at the turning points, because the change of direction suddenly takes effect. Cornering is not possible because of the unrest applicable., - - Crank drives by means of connecting rods have the advantage of a gentle Change of direction, because the increase and decrease in speed are sinusoidal take place. But also this sinusoidal change in speed and direction. is still noticeable. Try to reduce the vibrations with rubber couplings dampening only partially achieved the goal.

Es hat sich nun gezeigt, daß der Einbau einer elastischen Pleuelstange .gemäß der Erfindung einen schwingungs- und stoßfreien Lauf ergibt. Die Pleuelstange gibt in den Tötpunktlagen in beiden Richtungen sowie auch in den Beschleunigungs-und Verzögerungsperioden derart elastisch nach, äaß der Schlitten frei ausschwingen kann.. Unruhen werden von der Pleuelstange absorbiert, so daß auch Schallschwingungen des Getriebes nicht bis zur Arbeitsstelle gelangen können. In .der Zeichnung ist eine Ausführungsform einer elastischen Pleuelstange gemäß .der Erfindung in A.bh. i in Seitenansicht, in Abb. a in Oberansicht dargestellt.It has now been shown that the installation of an elastic connecting rod .according to the invention results in a vibration and shock-free run. The connecting rod gives in the dead center positions in both directions as well as in the acceleration and Delay periods so elastic after that the slide swing freely can .. disturbances are absorbed by the connecting rod, so that also sound vibrations of the gearbox cannot reach the place of work. In .the drawing is an embodiment of an elastic connecting rod according to .der invention in A.bh. i in side view, shown in Fig. a in top view.

Hier ist die Stange a wellenlinienförmig, z. B. aus Flachstahl mit rechteckigem Querschnitt, gebogen, wobei nach dem, Biegen eine Härtung erfolgt. Die beiderseitigen Enden der Pleuelstange laufen flach in .gleicher Ebene aus und sind hier, z. B. durch Schrauben b, mit den beiderseitigen Lagern verbunden. Die Enden der, Stange sind bei c rechtwinklig hakenförmig umgekantet und greifen in entsprechende Nuten der Verbindungsflansche d ein.Here the rod a is wavy, e.g. B. from flat steel with rectangular cross-section, bent, with hardening taking place after the bending. The ends of the connecting rod on both sides run flat in the same plane and are here, e.g. B. by screws b, connected to the bearings on both sides. the The ends of the rod are folded over at right angles in the shape of a hook at c and engage in corresponding grooves in the connecting flanges d.
