Description

Die Erfindung betrifft eine Einrichtung an Werkzeugmaschinen von Art der Schnekken- und Gewindeschleifmaschinen, Abwälzräderfräsmaschinen, Hinterdrehbänke, Hinterschleifmaschinen usw., bei denen es unerläßlich ist, Werkzeug und Werkstück weitestgehend zwangsläufig und gesetzmäßig zusammenarbeiten zu lassen.The invention relates to a device on machine tools of the type of worm and thread grinding machines, hobbing machines, backing lathes, relief grinding machines etc., where it is essential, tool and workpiece as much as possible to inevitably and legally cooperate.

Es ist bei derartigen Maschinen bekannt,It is known in such machines

ίο' das Getriebe, das die gegenseitige gesetzmäßige Abhängigkeit von Werkzeug- und Werkstückbewegung bewirkt, unabhängig von der im Betrieb sich einstellenden Belastung in gewissen Übertragungssträngen beliebig vorzubelasten, um möglichste Gleichförmigkeit in den verschiedenen Drehbewegungen zu erreichen. ίο 'the gear that is mutual lawful Dependence on tool and workpiece movement causes, regardless of to arbitrarily pre-load the load that occurs during operation in certain transmission lines, in order to achieve the greatest possible uniformity in the various rotary movements.

Zu dem Zweck ist beispielsweise an letzter Stelle des Getriebestranges 7-4 der in der Zeichnung schematisch dargestellten Schnekkenschleifmaschine ein Kraftverbraucher 8 eingeschaltet, z. B. eine Bremse, eine Druckpumpe usw., der gestattet, je nach Zweckmäßigkeit alle entsprechenden Getriebeteile mehr oder weniger stark vorzubelasten.For this purpose, for example, in the last position of the gear train 7-4 in the Drawing schematically shown worm grinding machine a power consumer 8 switched on, z. B. a brake, a pressure pump, etc., which allows, depending on the expediency, all appropriate gear parts to bias more or less heavily.

Es hat sich nun als zweckmäßig herausgestellt, bei Maschinen, die abwechselnd mil Arbeits- und Leerhüben arbeiten, die Kraftverbraucher nur während des Arbeitshubes wirksam werden zu lassen, während des Leerhubes (Rücklaufes) aber abzuschalten, um beim Rücklauf Arbeit zu sparen, den Verschleiß der Bremseinrichtung niedrig zu halten und eine unnötige Erwärmung des Kraftverbrauchers bzw. des Treibmittels, beispielsweise des Öles, zu vermeiden.It has now been found to be useful for machines that alternate mil Working and idle strokes work, the power consumers only during the working stroke to take effect, but switch off during the idle stroke (return) in order to to save work when reversing, to keep the wear of the braking device low and unnecessary heating of the power consumer or the propellant, for example of the oil.

Das Abschalten des Kraftverbrauchers beim Rücklauf der Maschine kann beispielsweise dadurch, erfolgen, daß ein Freilauf in Tätigkeit tritt oder z. B. der Kraftverbraucher leer läuft usw.Switching off the power consumer when the machine is reversing can, for example be done in that a freewheel comes into action or z. B. the power consumer empty running etc.
