Description
Kreuzgelenk-Teleskopwelle. Es ist bekannt, dass Kreuzgelenk-Tele skopwellen die Drehbewegung der Antriebs welle auf die anzutreibende Welle nur unter gewissen Bedingungen gleichförmig übertra- gen. Eine .dieser Bedingungen ist die gleiche Lage der beiden Endstücke der Zwischen welle in Bezug auf letztere. Bei zum Beispiel quadratischem Querschnitt der
ineinander- geschobenen Teile der Zwischenwelle besteht nun aber ,die Möglichkeit, dass diese Wellen teile mit ihren Endstücken um 9a' zuein ander verdreht .zusammengesteckt werden können, was eine ungleichförmige Drehbewe gung der angetriebenen Welle zur Folge hat.
Die Erfindung bezweckt nun, diesen <B>Übel-</B> stand zu beseitigen, und zwar ,dadurch, dass die unverdrehbar ineinander geschobenen Teile der Zwischenwelle eine solche Quer- schnittsform haben, dass säe nur in gleich liegender Stellung ihrer Endstücke in, Bezug auf die Zwischenwelle ineinandergeschoben werden können.
Auf der Zeichnung ist ein Ausführungs- beispiel des Erfindungsgegenstandes darge stellt, und zwar ist: Fig. 1 teilweise ein Längsschnitt und teil- weise eine Ansicht desselben und Fig. 2 ein Querschnitt hierzu. Es bezeichnen 1 und 2 die beiden, inein ander gesteckten Teile der Teleskopwelle, an deren Enden mittels Zapfen 3 die einen Ga belstücke 4 der Kreuzgelenke 4, 5 befestigt sind.
Die Gabelstücke 4 müssen zur gleich- förmigen Übertragung der Drehbewegung der Antriebswelle 6 oder 7 auf,die Abtriebs welle 7 bezw. 6 in Bezug zur Teleskopwelle gleiche Lage haben. Da-mit nun die beiden Wellenteile 1 und 2:
nur so zusammengesteckt werden können, dass die Endstücke 4 unter allen Umständen genannte gleiche Lage haben,\haben die Wellenteile 1, 2 rechteckigen Querschnitt. Dies ist die walz- oder zieh technisch einfachsIe, nur um 1$0 verwech- selbare Querschnittsform.
Es könnte aber auch eine andere, von .der kreisrunden oder quadratischen Quem@chnittsform abweichende, nicht oder nur um 1$0 verwechselbare un- gleichseitge, nicht planparallele Querschnitts form vorgesehen sein, z. B. eine prismatische, rhombische usw.
Universal joint telescopic shaft. It is known that universal joint telescopic shafts transmit the rotational movement of the drive shaft to the driven shaft uniformly only under certain conditions. One of these conditions is the same position of the two end pieces of the intermediate shaft in relation to the latter. For example, with a square cross-section
However, parts of the intermediate shaft that are pushed into one another can now be plugged together with their end pieces rotated by 9a 'to one another, which results in a non-uniform rotational movement of the driven shaft.
The aim of the invention is to eliminate this deficiency, namely by virtue of the fact that the non-rotatable parts of the intermediate shaft that are pushed into one another have such a cross-sectional shape that their end pieces would only be in the same position. Can be pushed into each other with respect to the intermediate shaft.
The drawing shows an exemplary embodiment of the subject matter of the invention, namely: FIG. 1 partially a longitudinal section and partially a view of the same, and FIG. 2 a cross section of this. It denotes 1 and 2, the two, inein other inserted parts of the telescopic shaft, at the ends of which by means of pins 3 the one Ga belstück 4 of the universal joints 4, 5 are attached.
The fork pieces 4 must for uniform transmission of the rotational movement of the drive shaft 6 or 7, the output shaft 7 respectively. 6 have the same position in relation to the telescopic shaft. So now the two shaft parts 1 and 2:
can only be plugged together so that the end pieces 4 have the same position mentioned under all circumstances, the shaft parts 1, 2 have a rectangular cross-section. This is the technically simplest rolling or drawing, cross-sectional shape that can only be confused by 1 $ 0.
But it could also be a different, from .der circular or square cross-sectional shape, not or only by 1 $ 0 confusable unequal, non-plane-parallel cross-sectional shape be provided, z. B. a prismatic, rhombic, etc.
