 überhaupt eine   stärkere   Bauart der ganzen Anlage. 



   Die Erfindung bezieht sich auf die Lagerung von Schaufehädern. insbesondere von mit- 
 EMI1.2 
 Bauart und soll dazu dienen, die mit der Erfindung erzielten Vorteile vergleichsweise deutlich zum Ausdrucke zu bringen. 



   Die Lagerung der Schaufelräder Y erfolgt durch Vermintlung einer als Lager büchse ausgebildeten   höhlen Wene , die sich auf   der feststehenden Achse 3 dreht. 



   Diese Anordnung   weise gegenüber   der bekannten Bauart (Fig. 2) folgende Vorteite auf : Da   die feststehende Achse ais   an beiden Enden fest eingespannt zu betrachten ist, verringert 
 EMI1.3 
 in der freien Spannlänge nicht   eingerechnet,   dreimal so gross wie bei der   eingespannLen Achse.   



   Um bei derartigen rasch laufenden   Schaufelrädern   unterhalb der kritischen Umdrehungszahl zu bleiben, bei der die freie Spannlänge in der dritten Potenz in   Rechnung fällt,   muss infolge des Unterschiedes in der   Spanniänge   eine um so bedeutendere Überbremessung erlolgen. 



   Da beim Erfindungsgegenstande die Achse nur auf reine unveränderliche Biegung beansprucht ist. entfällt mit. der wechselnden Beanspruchung auch eine wichtige Ursache für die Verstärkung der Schwingungen und der dadurch bedingten stärkeren Bemessung. 



   Wenn somit festgestelli ist. dass die feststehende   Achse   heim Erfindungsgegenstand weit

 EMI1.1
 generally a stronger construction of the whole system.



   The invention relates to the storage of display wheels. especially from
 EMI1.2
 Design and should serve to bring the advantages achieved with the invention to expression comparatively clearly.



   The storage of the paddle wheels Y is carried out by mining a hollow Wene designed as a bearing sleeve, which rotates on the fixed axis 3.



   This arrangement has the following advantages over the known design (FIG. 2): Since the fixed axis is to be considered firmly clamped at both ends, it is reduced
 EMI1.3
 Not included in the free span length, three times as large as with the clamped axis.



   In order to stay below the critical number of revolutions at which the free span length is taken into account to the power of three with such rapidly rotating paddle wheels, an overbraking must be all the more significant due to the difference in the span length.



   Since in the subject matter of the invention, the axis is only subject to pure unchangeable bending. omitted with. The changing stress is also an important reason for the amplification of the vibrations and the resulting stronger dimensioning.



   If it is thus established. that the fixed axis is far from the subject of the invention

 length the entire structural formation in a favorable manner.

PATIENT-ANSPRUCH : Lagerung der Schaufelräder von Schleudergebläsen, Turhokompressoren u. dgl., daduich gekennzeichnet, dass die Schaufelräder auf einer feststehenden, an beiden Enden fest eingespannten chse drehbar gelagert sind. so dass die ganze freie Spannlänge der Achse zur Lauffläche ausgenutzt wird, um eine Verringerung des Durchmessers der Achse und damit sämtlicher Abmessungen der baulichen Teile zu ermöglichen. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATIENT CLAIM: Storage of the blades of centrifugal fans, turbo compressors and the like. The like., characterized in that the paddle wheels are rotatably mounted on a stationary axis that is firmly clamped at both ends. so that the entire free span length of the axis to the running surface is used to allow a reduction in the diameter of the axis and thus all dimensions of the structural parts. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
