Abstract

In these multi-stage axial compressors, all the impellers are mounted in series on a drive shaft and are driven by a motor. In this arrangement, every other impeller is guided on both faces, via 3 friction discs whose roof-shaped running faces run in the central grooves of the impellers, in an overhung manner and so as to be twisted in a contrary sense with respect to the drive shaft, which obviates a separate support of the friction-wheel cages and the contrarotating impellers.

Claims (1)

anspruchs 1.claim 1. Ähnliche Ausführungen sind aus den Patentschriften DE-PS 947 198 und GB-PS 7 68 268 zu ersehen. Sie haben den Nachteil, daß alle auf der Achse angeordneten drehbar gelagerten Schaufelräder und Reibradkäfige Gleit- oder Kugellager benötigen. Similar statements are from the patent specifications DE-PS 947 198 and GB-PS 7 68 268 can be seen. They have the disadvantage that they are all arranged on the axis rotatably mounted paddle wheels and friction wheel cages require sliding or ball bearings. Der Erfindung lag die Aufgabe zugrunde, alle diese Lager zu beseitigen. The invention was based on the object of eliminating all of these bearings. Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1. The solution to this problem is carried out with the features of the characteristic Part of claim 1. Vorteilhafterweise sind die Reibscheiben dachförmig abgeschrägt und das Rillenprofil in den Schaufelrädern ist in axialer Richtung elastisch, damit beim Montieren der Schaufelräder die erforderliche Reibkraft für ein bestimmtes Drehmoment eingestellt werden kann. Advantageously, the friction disks are beveled and roof-shaped the groove profile in the paddle wheels is elastic in the axial direction, so when assembling the paddle wheels the necessary frictional force for a particular Torque can be adjusted. Die Erfindung bietet mehrere Vorteile. Durch den Wegfall der Kugellager verbilligt sich der Bau eines Verdichters. Es lohnt sich jetzt auch mehrstufige Ventilatoren herzustellen, welche mit kleinen Drehzahlen sehr leise laufen und dabei noch genügend Druck bringen und außerdem aus Kunststoff gespritzt werden können. Gegenüber einem Verdichter mit feststehenden Leitschaufeln verringert sich die Schaufelzahl um die Hälfte und ebenso auch die Baulänge des Verdichters. The invention offers several advantages. By eliminating the ball bearings the construction of a compressor becomes cheaper. It is now also worthwhile to have multi-level Manufacture fans that run very quietly at low speeds and at the same time still bring enough pressure and can also be injected from plastic. Compared to a compressor with fixed guide vanes, the number of vanes is reduced by half and also the length of the compressor. Die Reibungsverluste an den Schaufeln sind durch die halbierte Schaufeloberfläche auch nur halb so groß.The friction losses on the blades are due to the blade surface being halved also only half the size. In den Fi g. 1 und 2 wird eine Ausführungsform der Erfindung im einzelnen beschrieben. In the Fi g. Figures 1 and 2 illustrate an embodiment of the invention in more detail described. F i g. 1 zeigt die Stirnseite des Verdichters im Schnitt. F i g. 1 shows the front of the compressor in section. F i g. 2 zeigt die Ansicht des Verdichters im Schnitt. F i g. 2 shows the view of the compressor in section. Die Antriebswelle (1) ist in den Lagern (2) und (3) drehbar gelagert und wird von einem Motor angetrieben. Über die Speichen (4) wird das Gehäuse (5) mit den Lagern (2) verbunden. Die Schaufelräder (6) und (8) sitzen fest auf der Antriebswelle. Das dazwischenliegende Schaufelrad (7) hat keine direkte Verbindung zur Antriebswelle, sondern wird auf der linken Seite von den 3 Reibscheiben (10) mittels der zentrischen Rillen (11) geführt und verdreht. Je 3 Reibscheiben sind in einem Käfig (12) und (13) drehbar gelagert. Die Reibscheibenachsen (20) stehen senkrecht zur Antriebswelle. In den zentrischen Rillen (14) und (15) der Schaufelräder (6) und (8) laufen die Reibscheiben (9) und (10). Die beiden Käfige (12) und (13), in denen die Reibscheiben drehbar gelagert sind, werden über die am Gehäuse festgemachten Stäbe (18) und (19), gegen Verdrehung gesichert. The drive shaft (1) is rotatably mounted in the bearings (2) and (3) and is driven by a motor. The housing (5) is attached to the spokes (4) connected to the bearings (2). The paddle wheels (6) and (8) sit firmly on the Drive shaft. The paddle wheel (7) in between has no direct connection to the drive shaft, but is held on the left by the 3 friction disks (10) guided and twisted by means of the central grooves (11). There are 3 friction disks each rotatably mounted in a cage (12) and (13). The friction disk axes (20) are in place perpendicular to the drive shaft. In the central grooves (14) and (15) of the paddle wheels (6) and (8) run the friction disks (9) and (10). The two cages (12) and (13), in which the friction disks are rotatably mounted, are fastened to the housing via the Rods (18) and (19) secured against rotation. Dadurch dreht sich das Schaufelrad (7) entgegengesetzt zur Antriebswelle. Die Laufrillen (11), (14), (15) sind in axialer Richtung elastisch. Da das auf der Welle festgemachte Schaufelrad, sowie das entgegengesetzt drehende Schaufelrad in der gleichen Richtung fördert, hat das eine Rad die Schaufelstellung (16) und das andere die Schaufelstellung (17). Je nach Bedarf kann die Anzahl der Schaufelräder vergrößert werden.As a result, the paddle wheel (7) rotates in the opposite direction to the drive shaft. The grooves (11), (14), (15) are elastic in the axial direction. Since that is on the Shaft fixed impeller, as well as the oppositely rotating impeller in promotes in the same direction, one wheel has the blade position (16) and that others the blade position (17). Depending on your needs, the number of paddle wheels be enlarged.
