Description

Druckluftdrehkolbenmotor mit umsteuerbarer Drehrichtung Die Erfindung bezieht sich auf einen Druckluftdrehkolbenmotor mit umsteuerbarer Drehrichtung, dessen Rotor mit Schlitzen zur Führung von Treibschiebern versehen ist und bei dem zum Anfahren die Treibschieber mittels über Innenbohrungen zugeführter Druckluft gegen die Zylinderwand gedrückt werden, wie solche zum Antrieb von Werkzeugen, wie Schleifscheiben, Bohrern u. dgl., Verwendung finden.Pneumatic rotary piston motor with reversible direction of rotation The invention refers to a pneumatic rotary piston motor with reversible direction of rotation, whose rotor is provided with slots for guiding drive vanes and in which to start up the drive valve by means of compressed air supplied via internal bores are pressed against the cylinder wall, such as those for driving tools, such as Grinding wheels, drills and the like, find use.

Während bei den bekannten Druckluftmotoren die Umschaltung der Drehrichtung unmittelbar beim Motor erfolgen muß, ist dies nach der vorliegenden Erfindung örtlich unabhängig, da hier lediglich die Druckluft umzusteuern ist, während alles weitere mittels Umleitventilen am Motor selbsttätig erfolgt.While in the known air motors, the direction of rotation is switched must take place directly at the engine, this is local according to the present invention independent, since here only the compressed air has to be reversed, while everything else takes place automatically by means of bypass valves on the engine.

Der erfindungsgemäße Druckluftdrehkolberunotor mit umsteuerbarer Drehrichtung, dessen Rotor mit Schlitzen zur Führung von Treibschiebern versehen ist und bei dem zum Anfahren die Treibschieber mittels über Innenbohrungen zugeführter Druckluft gegen die Zylinderwand gedrückt werden, kennzeichnet sich hierzu dadurch, daß zur Drehrichtungsänderung im Motorgehäuse axial vor dem Arbeitszylinder und senkrecht zur Maschinenhauptachse zwei einander parallele Bohrungen angeordnet sind, die beide an je einem ihrer Enden mit einem von zwei getrennten Druckluftzufuhrkanälen verbunden sind, wovon die erste in der Mitte mit einem Austrittskanal verbunden ist und einen Doppelkolbenschieber zur selbsttätigen Umleitung der Zu- und Abluft bei Umschaltung der Druckluftzufuhr in den beiden Zufuhrkanälen aufnimmt und wovon die zweite ein Kugelventil enthält, das selbsttätig die Druckluftzufuhr zu einer Zentralbohrung im Drehkolben zum Ausfahren der Treibschieber steuert.The compressed air rotary piston rotor according to the invention with reversible direction of rotation, the rotor of which is provided with slots for guiding drive slides and in which the drive slides are pressed against the cylinder wall by means of compressed air supplied via internal bores for starting up, is characterized in that to change the direction of rotation in the motor housing axially in front of the working cylinder and perpendicular mutually parallel bores are arranged to the machine main axis, two, both of which are connected at each one of its ends with a separate two air supply channels, the first of which in the center with an outlet channel is connected, and a double piston valve for the automatic redirection of the supply and exhaust air when switching which receives compressed air supply in the two supply channels and of which the second contains a ball valve which automatically controls the compressed air supply to a central bore in the rotary piston for extending the drive slide.

Eine Ausführungsform eines erfindungsgemäßen Druckluftdrehkolbenmotors mit umsteuerbarer Drehrichtung ist beispielsweise in der Zeichnung dargestellt, und zwar zeigen F i g. 1 und 2 die Längsschnitte nach Linie I-II eines Druckluftdrehkolbenmotors in zwei verschiedenen Antriebsrichtungen, F i g. 3 und 4 den Querschnitt nach Linie 111-III und einen vergrößerten Ausschnitt A hiervon.An embodiment of a pneumatic rotary piston motor according to the invention with reversible direction of rotation is shown, for example, in the drawing, namely FIG. 1 and 2 the longitudinal sections along line I-II of a compressed air rotary piston engine in two different drive directions, F i g. 3 and 4 show the cross section along line 111-III and an enlarged detail A thereof.

Wie aus der Zeichnung ersichtlich ist, liegt der Stator 1 im Gehäuse 2 und nimmt in der exzentrischen Bohrung 3, welche als Arbeitszylinder dient, den Rotor 4 auf, der als Drehkolben wirkt. Der Rotor 4 führt in Schlitzen die Treibschieber 5, auf welche die Druckluft zum Antrieb des Drefikolbens wirkt. Der Rotor 4 läuft beidseits in Kugellagern der Lagerringe 6, 7, wobei sich einerseits die Luftein- und -auslässe 8, 9, 10 und andererseits das Getriebe 11 mit Getriebehülse 12 und Werkzeugaufnahme 13 anschließen.As can be seen from the drawing, the stator 1 lies in the housing 2 and receives the rotor 4, which acts as a rotary piston , in the eccentric bore 3, which serves as a working cylinder. The rotor 4 guides the drive slide 5 in slots, on which the compressed air acts to drive the three-piston piston. The rotor 4 runs on both sides in ball bearings of the bearing rings 6, 7, the air inlets and outlets 8, 9, 10 on the one hand and the gear 11 with gear sleeve 12 and tool holder 13 connecting on the other.

Nach F i g. 1 erfolgt der Lufteintritt bei 8 und stellt den Doppelkolbenschieber 14 nach oben. Vor Eintritt in den Arbeitszylinder 3 durch die Luftzuleitung 15 mit Eintrittstasche 16 wird Druckluft über das Kugelventil 17 entnommen und gelangt über die Längsbohrung 18 und die Radialbohrungen 19 zentral auf die Schieber 5 und führt diese somit nach außen, so daß ein zügiger Anlauf gewährleistet wird. Die Druckluft im Arbeitszylinder 3 gelangt nach geleisteter Arbeit über die Austrittstasche 20 mit Luftableitung 21 am Doppelkolbenschieber 14 vorbei zum Luftaustritt 10. According to FIG. 1 , the air inlet takes place at 8 and moves the double piston valve 14 upwards. Before entering the working cylinder 3 through the air supply line 15 with inlet pocket 16 , compressed air is withdrawn via the ball valve 17 and reaches the slide 5 centrally via the longitudinal bore 18 and the radial bores 19 and thus leads them to the outside, so that a quick start-up is guaranteed. After the work has been performed, the compressed air in the working cylinder 3 reaches the air outlet 10 via the outlet pocket 20 with air discharge 21 past the double piston slide 14.

Bei F i g. 2 ist die Luftzuleitung, wie ersichtlich, entsprechend umgestellt, d. h., der Lufteintritt erfolgt hier über 9 bei selbständig umgesteuertem Doppelkolbenschieber 14 und Kugelventil 17, wobei sich die Kugel immer an die öffnung geringsten Drucks legt, in umgekehrter Richtung über 21, 20 nach 16, 15 am Doppelkolbenschieber 14 vorbei zum Luftaustritt 10, der beidesmal derselbe ist. lEermit kann durch einfache Umlegung des Lufteintritts von 8 nach 9 die Drehrichtung umgesteuert werden, wobei in jedem Falle die Schieber mittels vor Eintritt in den Arbeitszylinder entnommener Druckluft gegen die Zylinderwand 3 geführt sind. Der Doppelkolbenschieber 14 liegt, wie aus der Zeichnung ersichtlich ist, parallel zum Kugelventil 17, wobei erfindungsgemäß eine Umsteuerung bei Umschaltung der Druckluftzufuhr in den beiden Zufuhrkanälen erfolgt.At F i g. 2 the air supply line is, as can be seen, adjusted accordingly, i.e. In other words, the air inlet takes place via 9 with independently reversed double piston valve 14 and ball valve 17, whereby the ball is always at the opening of the lowest pressure, in the opposite direction via 21, 20 to 16, 15 past the double piston valve 14 to the air outlet 10, the both times is the same. The direction of rotation can be reversed by simply shifting the air inlet from 8 to 9 , whereby in each case the slides are guided against the cylinder wall 3 by means of compressed air taken before entry into the working cylinder. As can be seen from the drawing, the double piston valve 14 lies parallel to the ball valve 17, whereby, according to the invention, a reversal takes place when the compressed air supply is switched over in the two supply channels.
