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

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
EMI1.4
length the entire structural formation in a favorable manner.
