Description
Kolbentrommel-Lagerung für Drehkolbenmaschinen mit sichelförmigem Arbeitsraum und radial verschiebbaren Kolben. Die Erfindung betrifft eine Drehkolbenmaschine mit sichelförmigemArbeitsraum und radial verschiebbaren Kolben und bezweckt, für solche Maschinen einen möglichst ge-. ringen Raumbedarf zu erreichen. Das wird dadurch bewirkt, daß die Lagerstellen der Drehkolbenachse oder auch nur eine dieser Lagerstellen nach dem Innern der- Maschine zu .eingezogen werden, wobei die Zylinderdeckel eine Einstülpung erfahren.Piston drum bearing for rotary piston machines with sickle-shaped Working space and radially displaceable piston. The invention relates to a rotary piston machine with sickle-shaped working space and radially displaceable piston and intended for such machines are as good as possible. strive to achieve space requirements. That will make it causes the bearing points of the rotary piston axis or only one of these bearing points be drawn in to the inside of the machine, the cylinder cover being a Experience indentation.
Um die bekannte Abstützung der Kolben gegen ihre Fliehkräfte beibehalten zu können, wird als Folge des geringen noch zur Verfügung stehenden Raumes nur noch ein einziger Stützring verwendet, der in der Schwerebene -der Kolben liegt und der von einem Lagerhals eines eingestülpten Zylinderdeckels, der entsprechend weit vorgezogen ist, getragen wird.In order to maintain the known support of the pistons against their centrifugal forces as a result of the small amount of space still available a single support ring is used, which lies in the plane of gravity -the piston and the from a bearing neck of an inverted cylinder cover, which is pulled forward accordingly is, is worn.
Werden beide Zylinderdeckel eingestülpti -so verengt sich die Berührungsfläche zwischen Kolben und Kolbenachse derart, daß ein zuverlässiges Aufkeilen nicht mehr geschehen kann, und es ergibt sich deshalb als weitere Folge, däß der Kolben für Maschinen dieser Art mit seiner Achse aus einem einzigen Stück hergestellt wird, so daß er den hohen Beanspruchungen durch die Fliehkraft standhält.If both cylinder covers are turned in, the contact area narrows between the piston and piston axis in such a way that reliable wedging is no longer possible can happen, and it therefore follows as a further consequence that the piston for Machines of this type are made with its axis from a single piece, so that it withstands the high stresses caused by centrifugal force.
In der Zeichnung ist die Erfindung in zwei Ausführungsformen wiedergegeben.In the drawing, the invention is shown in two embodiments.
Abb. i zeigt einen Längsschnitt mit einem eingestülpten Zylinderdeckel, Abb. 2 einen solchen mit Einstülpung beider Zylinderdeckel, Abb. 3 einen Schnitt nach Linie A-B der Abb. 2.Fig. I shows a longitudinal section with an inverted cylinder cover, Fig. 2 shows one with the invagination of both cylinder covers, Fig. 3 shows a section according to line A-B of Fig. 2.
Die Kolbentrommelachse a besitzt die Lagerstellen b und c und trägt gemäß Abb. i die aufgekeilte Kolbentrommel d, in dessen , Schlitzen die Kolben e sich radial verschieben. Das Lager c ist dadurch nach dem Innern der Maschine zu eingezogen, daß der Lagerdeckel f bei g eingestülpt ist. Um Raum für diese Einstülpung zu schaffen, besitzt die Kolbentrommel eine Ausnehmung h.The piston drum axis a has the bearings b and c and carries according to Fig. i the wedged piston drum d, in whose slots the pistons e move radially. The bearing c is thus closed towards the inside of the machine drawn in that the bearing cap f is inverted at g. To make room for this indentation to create, the piston drum has a recess h.
Die Einstülpung g des Zylinderdeckels ist bis über die Mittelebene der Maschine hinaus vorgezogen, so daß ein Lagerhals i entsteht, der .als Träger für den einzigen Stützring h dient, so daß die Kolben in der an sich bekannten Weise gegen ihre Fliehkräfte abgestützt werden, und zwar in ihrer Schwerlinie, damit keine schädlichen Seitenkräfte entstehen. Der Stützring k läuft, wie üblich, auf Rollen 1.The indentation g of the cylinder cover is above the center plane the machine pulled out, so that a bearing neck i arises, the .as a carrier for the single support ring h is used, so that the piston in the known manner be supported against their centrifugal forces, namely in their center of gravity, so none harmful side forces arise. The support ring k runs, as usual, on rollers 1.
Die Einrichtung nach Abb. 2 entspricht derjenigen nach Abb. i. Es besteht nur insoweit ein Unterschied, als auch der Zylinderdeckel f leingestülpt ist, so daß der Kolben d außer der Ausnehmung h auch noch eine solche hl besitzt. Das Lager b kommt dabei ebenfalls mehr nach der Maschinenmittelebene zu liegen, so daß @es nicht mehr als vorspringender Teil der Maschine besteht. Es wird von der Einstülpung g1 des Deckels/' getragen. Da nun für die Befestigung der Kolbentrommel d auf der Achse a kaum noch die :erforderliche Fläche besteht, ist die Kolbentrommel mit ihrer Achse aus einem einzigen Stück hergestellt.The device according to Fig. 2 corresponds to that according to Fig. I. There is only a difference insofar as the cylinder cover f is also everted so that the piston d also has such a recess h in addition to the recess h. The bearing b also comes to lie more after the machine center plane, so that @it no longer exists as a protruding part of the machine. It is carried by the indentation g1 of the lid / '. Since there is now hardly the area required for fastening the piston drum d on the axis a, the piston drum with its axis is made from a single piece.
Die Erfindung hat nicht nur den Vorteil, den Raumbedarf der Maschine zu verringern, sondern ,gleichzeitig wird auch das Gewicht verringert und die Leistungsfähigkeit erhöht, weil sich die schwingenden Massen verkleinern.The invention not only has the advantage that the machine takes up space but, at the same time, it also reduces weight and performance increased because the vibrating masses decrease.
