Description
Gegenstand der Erfindung ist eine Abdichtung für Kapselwerke, bei der zwischen dem Gehäusedeckel und einer achsial verschiebbaren, gegen die Stirnseite der uinlaufenden Teile abdichtenden Zwischenscheibe mit dem Arbeitsraum der Maschine in Verbindung stehende Druckräume angebracht sind.The invention relates to a seal for capsule works in which between the housing cover and an axially displaceable, against the front side of the uinlaufenden Parts sealing intermediate disk with the working space of the machine in connection with pressure spaces attached are.
Es ist · bekannt, die Druckräume durchIt is known to pass through the pressure chambers
ίο Dichtungsstreifen zu bilden, die unter Federdruck gegen den Zylinderdeckel anliegen. Diese Einrichtung hat den Nachteil, daß an jedem Zylinderende zwei genau bearbeitete Dichtungsflächen vorhanden sein müssen, nämlich die Fläche der Zwischenscheibe, gegen die die umlaufenden Teile sich anlegen, und der Zylinderdeckel, gegen den die Dichtungsstreifen abgestützt sind. Zudem rufen die Federn ständig Reibungsverlusteίο to form sealing strips that are under spring pressure against the cylinder cover. This device has the disadvantage that two precisely machined at each end of the cylinder Sealing surfaces must be available, namely the surface of the intermediate disk against which the rotating parts rest, and the cylinder cover against which the weather strips are supported. In addition the springs constantly call frictional losses
so hervor, die bei kleiner Belastung den Wirkungsgrad stark herabsetzen.so that the efficiency under small loads greatly reduce.
Nach der Erfindung werden die Druckräume als Höhlungen im Gehäusedeckel und in der Zwischenscheibe oder in einem dieser Teile ausgebildet. Diese Druckräume können durch Dichtungsstreifen aus weichem Material gegen den Raum zwischen dem Gehäusedeckel und der Zwischenscheibe abgedichtet werden und bedürfen, keiner besonderen Bearbeitung. Aber auch der Zylinderdeckel kann unbearbeitet bleiben, da keine Dichtungsstreifen auf ihm arbeiten. Demnach braucht beim Erfindungsgegenstand nur die Innenfläche jeder Zwischenscheibe, nicht aber muß auch die Innenfläche der beiden Zylinderdeckel genau bearbeitet sein. Die Reibungsverluste durch den Druck der die Dichtungsstreifen andrückenden Federn fallen fort und der Druck, mit dem die Dichtungsscheibe an den Stirnflächen der umlaufenden Teile anliegt, ist dem Arbeitsdruck proportional, bei kleinerer Leistung, also entsprechend geringer.According to the invention, the pressure chambers as cavities in the housing cover and formed in the intermediate disk or in one of these parts. These pressure spaces can by sealing strips made of soft material against the space between the housing cover and the washer are sealed and do not require any special Editing. But the cylinder cover can also remain unprocessed, as there are no sealing strips on it. Therefore only needs the inner surface of each intermediate disk in the subject matter of the invention, not but the inner surface of the two cylinder covers must also be precisely machined. The friction losses due to the pressure of the the springs pressing on the sealing strips and the pressure with which the Sealing washer rests on the end faces of the rotating parts, is the working pressure proportional, with lower power, i.e. correspondingly lower.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes darg©- stellt.An exemplary embodiment is shown in the drawing of the subject matter of the invention darg © - represents.
Abb. ι ist auf der linken Seite ein Schnitt durch den Zylinder, der die Außenfläche der Zwischenscheibe zeigt, von links in Abb. 2 gesehen, auf der rechten Seite eine Ansicht der Innenseite der Zwischenscheibe, von rechts in Abb. 2 gesehen.Fig. Ι is on the left a section through the cylinder, which is the outer surface of the intermediate disk shows, seen from the left in Fig. 2, a view on the right side the inside of the washer, seen from the right in Fig. 2.
Abb. 2 ist ein Längsschnitt durch den Zylinder. Fig. 2 is a longitudinal section through the cylinder.
Auf der Welle ι ist die Kolbentrommel 2 mit den.: Kolben 3 befestigt, die in einem Gehäuse 4 umlaufen. Das Gehäuse ist durch einen Deckel 5 abgeschlossen. Zwischen dem Deckel und der Stirnfläche der Kolbentrommel und ihrer Kolben liegt eine achsial verschiebbare Dichtungsscheibe 6. Diese Scheibe ist auf die Stirnflächen der Kolben 3 und der Kolbentrommel dicht aufgeschliffen undOn the shaft ι is the piston drum 2 with the. : Pistons 3 attached, which rotate in a housing 4. The housing is closed by a cover 5. An axially displaceable sealing washer 6 is located between the cover and the end face of the piston drum and its piston. This washer is ground tightly onto the end faces of the piston 3 and the piston drum
ίο mit einer Nut 7 zur Aufnahme der Führungsrollen 8 der Kolben 3 versehen. Ein Anschlag 12 oder eine ähnliche Einrichtung sichert die Scheibe 6 gegen Drehung. 13 stellt das Widerlager der Maschine dar.ίο provided with a groove 7 for receiving the guide rollers 8 of the piston 3. An attack 12 or a similar device secures the disk 6 against rotation. 13 represents the abutment of the machine.
In dem Deckel 5 und der Scheibe 6- sind Hohlräume ausgespart, die paarweise Druckkammern 9 bilden. Jede Druckkammer ist durch Kanäle 10 mit dem Arbeitsraum der Maschine verbunden und mit Dichtumgsein-In the cover 5 and the disk 6- cavities are recessed, which form pressure chambers 9 in pairs. Each pressure chamber is connected to the working space of the machine by channels 10 and has a sealing element.
ao lagen, beispielsweise Lederstulpen 11, versehen, die verhindern, daß das Druckmittel in dem Raum zwischen der Scheibe 6 und dem Deckel 5 übertritt. Im vorliegenden Falle sind die Druckkammern 9,9 in zwei Reihen angeordnet, eine nahe am Mantel des Gehäuses 4, diel andere in der Nähe der Trommelwelle ι. Die Anzahl der Druckkammerneihen, die Anzahl der Druckkammern selbst, ihre Größe und ihre Verteilung richten sich nach den Abmessungen der Maschine.ao layers, for example leather gauntlets 11, provided, which prevent the pressure medium in the space between the disc 6 and the cover 5 exceeds. In the present case, the pressure chambers 9, 9 are in two Arranged in rows, one near the shell of the housing 4, the other near the drum shaft ι. The number of pressure chambers rows, the number of pressure chambers themselves, their size and distribution depend on the dimensions of the machine.
