Definitions
- the invention relates to a window seal for a swivel motor according to the preamble of patent claim 1.
- a swivel motor is known in the ribs of the cylinder and wings of a motor shaft disc seals are arranged, which separate adjacent working chambers from each other.
- the disc seals comprise a sealing frame in which an inner part is arranged together with a biasing ring.
- the inner part extends in the function of a filler in a plane parallel to the sealing frame and lies on the side.
- the filler In the direction of the sealing frame, the filler has a small transition radius between a surface to the groove bottom and the contact surface with the disk seal. In contrast, the transition radius at the filler in the direction of the groove side wall is made significantly larger.
- the small transition radius in the direction of the disk seal is intended to bring about as large a support as possible.
- the filler and the inner part are made in one piece. This results in the Advantage that the transition radii always fit the Greps on the sealing frame and the groove side wall. A wrong assembly is not possible.
- Fig. 2a represent the filler and the inner part separate components.
- This principle facilitates the standardization of the window seal with respect to different engine types by z. B. the filler pieces of the groove width adapts as needed.
- the problem arises that one wants to perform on the filler a small transition radius in the direction of the sealing frame and a large transition radius in the direction of the groove side wall on the one hand, without causing incorrect assembly.
- a very simple solution could be that the radius at the bottom of the groove to the groove side surface dimensioned very small. In terms of manufacturing technology, this design is feasible, but it promotes a notch effect on the rib or the wing.
- the object of the present invention is to find a solution to the known from the prior art problem of process-reliable alignment of the filler to the sealing frame.
- the object is achieved in that the sealing frame is provided on both sides with a filler and the filler pieces have on at least one side surface a position-oriented positive locking element.
- the interlocking elements of the filler pieces ensure a position-oriented installation position of the filler pieces to the sealing frame, so that the transition radii are aligned as intended to the filler pieces.
- the interlocking elements of the patches engage as projections in openings of the inner part. If one were to use the patches with the projections facing outwards, then the entire disk seal could not be inserted into a sealing groove. This would be apparent in the assembly process, the faulty arrangement of the filler to the sealing frame.
- the form-fitting elements of the filler pieces act as recesses with a projection of a groove side surface of a mounting device.
- the window seals are often mounted outside of the site in a device. In this device can be incorporated with little effort an axial groove in the groove side surface and thus guarantee the unique installation position of the filler.
- the form-locking elements are arranged offset parallel to a central axis of the filler.
- the filler can be mounted only in a single installation position to the sealing frame.
- the projections of the filler as a positive or negative form a holding connection and thus hold together a structural unit of the entire window seal.
- FIG. 1 shows a cross section through a window seal 1, whose basic structure, for example, already from the cited EP 1 150 018 A1 is known.
- a sealing frame 3 an inner part 5 is arranged, the z. B. with regard to a targeted intrinsic elasticity of several layered arranged Einzelinnentellen 5a-5c is formed.
- the inner part biases the sealing frame 1 in its entire plane.
- the sealing frame 3 with its inner part 5 are on both sides putties 7; 9 attached, which are preferably made of plastic.
- Each filler 7; 9 has a length and width, such as the sealing frame 3, so that this with its side surfaces 11; 13 with a side surface 15; 17 of the filling pieces 7; 9 is in contact with the installation position.
- side surface 17; 29 To a side facing away from the sealing frame 3 side surface 17; 29 have the circumferential end surfaces 19; 21 of the filler 7; 9 a pronounced transition radius 31; 33 on.
- d. H. non-interchangeable mounting position of the filler 7; 9 to the sealing frame 3 is on the side surfaces 15; 17 of the filler each a position-oriented positive-locking element 35; 37 executed.
- the positive locking elements 35; 37 are formed in this embodiment by a projection which engages in an opening 39 of the inner parts 5a-5c. If you were the filler 7; 9 with a side facing away from the sealing frame 3 projection 35; 37 want to mount so the entire disc seal would not insert into a sealing groove, since the projections would rest on the component having the seal groove.
- Fig. 2 shows a disc seal 1 in an application in a sealing groove 41 of a wing 43 which is sealed against an inner wall 45 of a cylinder 42.
- the basic structure of the disc seal 1 corresponds to the description Fig. 1 , Deviating is the transition radius 31; 33 between the side surface 27; 29 in the direction of a groove bottom 49 made larger than a transition radius 51; 53 between the circumferential end face of the filling pieces 7; 9 and the inner wall 45 of the cylinder 47.
- a main axis 55 of the filler forms the central axis of the entire disk seal 1.
- the positive-locking elements 35; 37 both fillers 7; 9 unilaterally parallel to the central axis 55 of the filler pieces are arranged offset, so that only a single installation position for both patches is possible.
- the form-fitting elements which are designed as positive 35 and negative 37, engage in one another and enter a retaining connection, so that the window seal 1 represents a manageable structural unit. If you install the filler, for example, twisted around the central axis or swap the filler, then the projections of the filler would be during assembly on the sealing frame 3, thus signaling the faulty mounting position.
- the window seal 1 is preferably assembled in a device 57 in the assembly process. You can z. B. in the axial direction of the disc seal provide a slightly funnel-shaped sealing groove to facilitate the assembly as a whole. From the device, the finished mounted disc seal is brought by an axial movement in the sealing groove 41 to the sealed point.
- FIG. 3 shows the window seal 1 within the mounting device 57, which on a groove side wall 59; 61, a projection 35 made as a rib; 37 in the direction of the filler 7; 9 includes, for the positive connection, a recess 63; 65 in the direction of the groove side surface 27; 29 has.
- the filling pieces 7; 9 are not faulty pushed into the device 57, since the end faces of the filler would strike the device 57. Is the assembly for the patches 7; 9, however, executed correctly, then the entire disk seal along the rib can be pushed out of the device.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Lösung für das aus dem Stand der Technik bekannte Problem der prozesssicheren Ausrichtung des Füllstücks zum Dichtungsrahmen zu finden.The object of the present invention is to find a solution to the known from the prior art problem of process-reliable alignment of the filler to the sealing frame.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Dichtungsrahmen beidseitig mit einem Füllstück versehen ist und die Füllstücke an mindestens einer Seitenfläche ein lageorientierendes Formschlusselement aufweisen.According to the invention the object is achieved in that the sealing frame is provided on both sides with a filler and the filler pieces have on at least one side surface a position-oriented positive locking element.
Die Formschlusselemente der Füllstücke sorgen für eine lageorientierte Einbaulage der Füllstücke zu den Dichtungsrahmen, so dass die Übergangsradien an den Füllstücken bestimmungsgemäß ausgerichtet sind.The interlocking elements of the filler pieces ensure a position-oriented installation position of the filler pieces to the sealing frame, so that the transition radii are aligned as intended to the filler pieces.
Bei einer ersten Ausführungsform greifen die Formschlusselemente der Füllstücke als Vorsprünge in Öffnungen des Innenteils ein. Wenn man die Füllstücke mit den Vorsprüngen nach außen weisen verwenden würde, dann ließe sich die gesamte Scheibendichtung nicht in eine Dichtungsnut einführen. Damit wäre im Montageablauf die fehlerhafte Anordnung des Füllstücks zum Dichtungsrahmen erkennbar.In a first embodiment, the interlocking elements of the patches engage as projections in openings of the inner part. If one were to use the patches with the projections facing outwards, then the entire disk seal could not be inserted into a sealing groove. This would be apparent in the assembly process, the faulty arrangement of the filler to the sealing frame.
Bei einer Alternativvariante wirken die Formschlusselemente der Füllstücke als Rücksprünge mit einem Vorsprung einer Nutseitenfläche einer Montagevorrichtung zusammen. Die Scheibendichtungen werden häufig außerhalb des Einsatzortes in einer Vorrichtung montiert. Bei dieser Vorrichtung kann man mit geringem Aufwand eine axiale Nut in deren Nutseitenfläche einarbeiten und damit die eindeutige Einbaulage der Füllstücke garantieren.In an alternative variant, the form-fitting elements of the filler pieces act as recesses with a projection of a groove side surface of a mounting device. The window seals are often mounted outside of the site in a device. In this device can be incorporated with little effort an axial groove in the groove side surface and thus guarantee the unique installation position of the filler.
In weiterer vorteilhafter Ausgestaltung der Erfindung sind die Formschlusselemente parallel versetzt zu einer Mittelachse des Füllstücks angeordnet. Damit lässt sich das Füllstück nur in einer einzigen Einbaulage zum Dichtungsrahmen montieren.In a further advantageous embodiment of the invention, the form-locking elements are arranged offset parallel to a central axis of the filler. Thus, the filler can be mounted only in a single installation position to the sealing frame.
Des Weiteren besteht die Option, dass die Vorsprünge der Füllstücke als Positiv oder Negativ eine Halteverbindung eingehen und damit eine Baueinheit der gesamten Scheibendichtung zusammenhalten.Furthermore, there is the option that the projections of the filler as a positive or negative form a holding connection and thus hold together a structural unit of the entire window seal.
Anhand der folgenden Figurenbeschreibung soll die Erfindung näher erläutert werden.The invention will be explained in more detail with reference to the following description of the figures.
