Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung bezieht sich auf Druckluftmaschinen mit umlaufenden Arbeitscylindern und je einem über jedem Arbeitscylinder gleichlaufend mit diesem angeordneten Steuerkolben zur Besorgung der Ein- und Auslässe. Die Steuerkolben werden durch je ein auf der feststehenden Kurbelwelle ebenfalls fest angebrachtes Excenter bewegt, dessen Ringe gelenkig mit den Kolben verbunden sind. Durch diese Anordnung wird ein aufserordentlich schnelles Umlaufen der Bohrmaschine und damit auch ein geringer Kraftverbrauch erreicht.The present invention relates to pneumatic machines with rotating working cylinders and one control piston arranged above each working cylinder in parallel with it for supplying the inlets and outlets. The control pistons are also fixed by one each on the stationary crankshaft attached eccentric moves whose rings are articulated to the piston. This arrangement enables the drilling machine to rotate extremely quickly thus also a low power consumption is achieved.

Die Zeichnungen veranschaulichen die Maschine. The drawings illustrate the machine.

Fig. ι zeigt einen senkrechten Schnitt durch die Mitte der Maschine.Fig. Ι shows a vertical section through the middle of the machine.

Fig. 2, 3 und 4 sind Querschnitte durch einen der Steuerkolben nach den Linien F- G-H der Fig. i.2, 3 and 4 are cross-sections through one of the control pistons along the lines F-GH of FIG.

Fig. 5 ist ein wagerechter Schnitt nach der Linie D-D der Fig. 1.FIG. 5 is a horizontal section along the line DD in FIG. 1.

Durch die Zuleitung 1 (Fig. 1), den Einlafs 3, das von der Feder 5 geschlossene, vom Drücker 2 zu öffnende Einlafsventil 4 und den an der Gehäusewandung entlang führenden Kanal 6 tritt die Druckluft in die hohle Kurbelwelle 7 und aus dieser durch mehrere radiale Bohrungen in den Kanal 9 ein (Fig. 1), der in dem Arbeitscylindergehäuse über den Cylindern ausgespart ist. Der Kanal 9 führt aufwärts durch Einlasse 11 in die Steuercylinder 10, in denen die Steuerkolben 12 arbeiten. Diese sind durch Arme 123 mit den Ringen der excentrischen Nabe 26 verbunden, welche die Verlängerung einer dem Gehäuse angegossenen Nabe bildet.Through the supply line 1 (Fig. 1), the inlet 3, the inlet valve 4, which is closed by the spring 5 and can be opened by the pusher 2, and the duct 6 leading along the housing wall, the compressed air enters the hollow crankshaft 7 and out of it through several radial bores in the channel 9 (Fig. 1), which is recessed in the working cylinder housing above the cylinders. The channel 9 leads upwards through inlets 11 into the control cylinders 10 in which the control pistons 12 work. These are connected by arms 12 3 to the rings of the eccentric hub 26, which forms the extension of a hub cast onto the housing.

Die Steuerkolben haben zwischen den beiden Enden 12 und 122 eine Verengung 121, welche beim gröfsten Hub des Excenters den Einlafs 11 mit dem Einlafs 13 am Ende der Arbeitscylinder 14 verbindet (Fig. 5) und Druckluft gegen das eine Ende der Kolben 1 5 treten läfst. Da die Kolbenstangen mit dem feststehenden Kurbelzapfen 18 gekuppelt sind, so werden die Cylinder in der Richtung des Pfeiles 28 (Fig. 5) umlaufen. Dabei werden die Excenter 26 mit ihren Ringen auf die Steuerkolben wirken, so dafs diese abwechselnd die Einlasse 11 und 13 verbinden bezw. die Luft am offenen Ende 16 des Steuerkolbencylinders 10 von dem Kanal 13 aus in das Gehäuse 8 leiten. Letzteres umgiebt die sich bewegenden Theile und läfst die Luft durch den Auslafs 17 austreten. Das Cylindergehäuse läuft mit dem Zapfen 19 in der Grundplatte des Gehäuses 8 und trägt am Zapfenende das Getriebe 20, das die Zahnräder 21, 22 antreibt, welche in die innere Verzahnung des mit dem Bohrfutter 24 versehenen Ringes 23 eingreifen.The control pistons have a constriction 12 1 between the two ends 12 and 12 2 , which during the largest stroke of the eccentric connects the inlet 11 with the inlet 13 at the end of the working cylinder 14 (Fig. 5) and compressed air against one end of the piston 1 5 kick. Since the piston rods are coupled to the stationary crank pin 18, the cylinders will rotate in the direction of arrow 28 (FIG. 5). The eccentrics 26 will act with their rings on the control piston so that they alternately connect the inlets 11 and 13 respectively. direct the air at the open end 16 of the control piston cylinder 10 from the channel 13 into the housing 8. The latter surrounds the moving parts and allows the air to escape through the outlet 17. The cylinder housing runs with the pin 19 in the base plate of the housing 8 and carries the gear 20 at the pin end, which drives the gears 21, 22 which mesh with the internal teeth of the ring 23 provided with the drill chuck 24.
