Description
Kraftverbraucher zur Beseitigung des Zahnspiels im Antrieb von Werkzeugmaschinen Die Erfindung betrifft eine Einrichtung an Werkzeugmaschinen von Art der Schnecken-, Schneckenfräser-, Wälzfräser- und Gewindeschleifmaschinen, Hinterdrehbänke, Hinterschleifmaschinen, Abwälzräderfräsmaschinen usw. mit Kraftverbraucher zur Beseitigung .des Zahn- oder sonstigen Spiels.Power consumer for eliminating backlash in the drive of machine tools The invention relates to a device on machine tools of the type of screw, Worm cutters, hob cutters and thread grinding machines, backing lathes, back grinding machines, Hobbing machines, etc. with power consumers to eliminate .des tooth or other game.
Bei bekannten Einrichtungen dieser Art wirkt der Kraftverbraucher lediglich als Bremse, die unter allen Betriebsverhältnissen Kraft verbraucht. Diese Einrichtungen sind unwirtschaftlich, denn sie verbrauchen unnötig Kraft, werden sehr warm und nutzen sich schnell ab.In known devices of this type, the power consumer acts only as a brake that consumes power under all operating conditions. These Facilities are uneconomical because they consume energy unnecessarily very warm and wear out quickly.
Bei anderen bekannten Einrichtungen dieser Art wird der Kraftverbraucher beim Rück-bzw. Leerlauf der Maschine abgeschaltet. Diese Einrichtungen arbeiten jedoch auch noch nicht einwandfrei und mit höchster Wirtschaftlichkeit, denn die bei diesen Einrichtungen erforderlichen Schaltorgane verwickeln und verteuern die Anlage und geben zu Störungen im Betriebe Veranlassung.In other known devices of this type, the power consumer when returning or. Machine idle switched off. These facilities work but also not flawlessly and with the highest economic efficiency, because the entangle switching elements required in these facilities and make them more expensive System and cause disruptions in the company.
Da bei diesen bekannten Einrichtungen das Getriebe nach dem Abschalten vom. Kraftverbraucher uribeeinflußt bleibt; so kann es vorkommen, daß das vorhandene Zahnspiel sich nachteilig auswirkt und ebenfalls zu Störungen im Betriebe führt.As in these known devices, the transmission after switching off from the. Power consumer remains influenced by uri; so it can happen that the existing Backlash has a detrimental effect and also leads to disruptions in operations.
Die günstigsten Ergebnisse liefert eine Einrichtung, bei der erfindungsgemäß der Kraftverbraucher ein von fremder Kraftquelle gespeister Motor ist, der beim Vor- und Rücklauf der Maschine eingeschaltet bleibt, und zwar derart, daß das in ihm erzeugte Drehmoment beim Vorlauf der Maschine eine Zurückhaltung des Getriebes bewirkt, beim Rücklauf dagegen zur Leistung der Rücklaufarbeit mitbenutzt wird.The most favorable results are obtained from a device in which, according to the invention the power consumer is a motor fed by an external power source, the Forward and reverse of the machine remains switched on in such a way that the in Torque generated a reluctance of the transmission as the machine advanced in return, on the other hand, it is used to perform the return work.
Hierdurch wird gegenüber den bekannten Einrichtungen eine erhebliche Kraftersparnis sowie ein ruhigerer Rücklauf erzielt, der meist sehr schnell erfolgen muß.This is a considerable compared to the known devices Energy savings and a quieter return are achieved, which usually take place very quickly got to.
Ferner können Störungen nicht vorkommen, weil der Kraftverbraucher das Getriebe ununterbrochen beeinflußt und so eine ungünstige Auswirkung des Zahnspiels nicht zuläßt.Furthermore, malfunctions cannot occur because the power consumer affects the transmission continuously and thus an unfavorable effect of the backlash does not allow.
Als Kraftquelle und als Kraftverbraucher können hydraulische, pneumatische, elektrische, oder auch andere Maschinen Verwendung finden.Hydraulic, pneumatic, electrical or other machines are used.
Ist an einer Werkzeugmaschine für irgendeinen Zweck eine Kraftquelle bereits vorhanden, so kann diese Kraftquelle (Hauptkraftquelle) auch für die Speisung des Kraftverbrauchers mitbenutzt werden.Is a power source on a machine tool for any purpose already available, this power source (main power source) can also be used for the supply of the power consumer can also be used.
Die Hauptkraftquelle wird in diesem Falle oft zu stark sein, so daß der Kraftverbraucher zu schwer belastet wird und daher unnötig viel Kraft verbraucht.The main source of power in this case will often be too strong, so that the power consumer is burdened too heavily and therefore uses a lot of power unnecessarily.
Erfindungsgemäß wird zur Vermeidung unnötigen Kraftverbrauchs zwischen
Kraftquelle und Kraftverbraucher eine Kr.aftminderungs-
