Description
Gelenkkupplung für die Übertragung der Drehbewegungen einer Welle auf eine zu dieser wenigstens zeitweise ungleichachsig stehende Welle, insbesondere für die Kraftübertragung elektrisch betriebener Gleisfahrzeuge. Bei Einzelachsantrieb für elektrische Lokomotiven handelt es sich darum, das Drehmoment des im Fahrzeugrahmen fest gelagerten Motors auf die abgefederte Triebachse zu übertragen. Zu diesem Zwecke benötigt man zwischen der treibenden und der getriebenen Achse eine nachgiebige Kupplung, welche die Drehbewegung ohne störende Ungleichförmigkeiten oder Stöße überträgt. Da aber die angetriebene Achse durch -die Ungleichförmigkeit der Gleise stets ihre Lage gegenüber dem Fahrzeugrahmen ändert, so ist es bis jetzt nicht gelungen, die gestellte Aufgabe zur Vollkommenheit zu lösen, und -man rnußte sich demgemäß begnügen, eine Konstruktion zu suchen, welche die auftretender Störungen auf ein Minimum vermindert.Articulated coupling for the transmission of the rotary movements of a shaft to a shaft which is at least temporarily unequally axially standing, in particular for the power transmission of electrically operated track vehicles. With single-axle drives for electric locomotives, it is a question of transferring the torque from the motor, which is fixedly mounted in the vehicle frame, to the sprung drive axle. For this purpose, a flexible coupling is required between the driving and the driven axle, which transmits the rotary motion without disturbing irregularities or jolts. But as the driven axle by - the unevenness of the track always changes its position relative to the vehicle frame, so it is up to now not been able to solve the task to perfection, and -man rnußte are accordingly satisfied to seek a construction which the occurring disturbances are reduced to a minimum.
Betrachtet man die auftretenden Verschiebungen zwischen Fahrzeugrahmen und Radachse, so sieht man, daß dieselben immer als Resultante von drei Komponenten betrachtet werden können, nämlich eine Parallelverschiebung .der Achsen (Exzentrizität der Achsen), eine Winkelveränderung zwischen den Achsen und eine seitliche Verschiebung des Radsatzes gegenüber dem Rahmen.Looking at the shifts that occur between vehicle frames and wheel axle, one can see that they are always the result of three components can be considered, namely a parallel shift of the axes (eccentricity of the axes), an angle change between the axes and a lateral shift of the wheelset compared to the frame.
Diese Verschiebungen geben ,zu Ungleichförmigkeiten der Drehbewegung Anlaß und infolgedessen zu zusätzlichen Kräften im Antrieb, welche durch Einbau eines federnden Gliedes zwischen der Kupplung und der Rotormasse vernichtet werden müssen.These displacements give rise to irregularities in the rotational movement Reason and consequently to additional forces in the drive, which by installation a resilient member between the clutch and the rotor mass are destroyed have to.
Weiter treten infolge der Reibungsarbeit der Kupplung zusätzliche, periodisch wechselnde Kräfte zwischen der antreibenden und der getriebenen Achse auf bzw. zwischen Fahrzeugrahmen und Radsatz, die durch ihre scharfen Richtungswechsel zu erheblichen Schwierigkeiten führen können.As a result of the friction work of the clutch, additional, periodically changing forces between the driving and the driven axle on or between the vehicle frame and wheelset, which are caused by their sharp change of direction can lead to significant difficulties.
Die Erfindung betrifft nun eine besondere Konstruktion einer derartigen Kupplung, welche die Beseitigung der obeherwähnten Fehlerquellen und besonders auch die Ungleichförmigkeit bei exzentrischen, parallelen Achsen auf ein Mindestmaß zu verhindern ermöglicht, ohne daß dadurch andere Nachteile in Kauf genommen werden müßten.The invention now relates to a particular construction of such a type Coupling, which eliminates the above-mentioned sources of error and especially the irregularity in eccentric, parallel axes is reduced to a minimum make it possible to prevent without other disadvantages being accepted as a result would have to.
Die in der Zeichnung schematisch als Ausführungsbeispiel des Erfindungsgegenstandes dargestellte Kupplung besteht aus zwei wenigstens annähernd parallelen Kupplungsstangen 5, 6, die einerseits mit den zwei z: B. mit der angetriebenen Welle (Triebrad T) sich drehenden Zapfen i, z und anderseits mit zwei durch Bolzen 9 sich scherenartig kreuzenden Hebeln 7 und 8 gelenkig verbunden sind. Von den andern beiden Scherenhebelenden ist das eine unmittelbar bei q., das andere über eine bewegliche Stange io bei 3 mit der antreibenden Welle (Antriebszahnrad Z) verbunden.The schematic in the drawing as an exemplary embodiment of the subject matter of the invention The coupling shown consists of two at least approximately parallel coupling rods 5, 6, on the one hand with the two e.g. with the driven shaft (drive wheel T) rotating pin i, z and on the other hand with two bolts 9 scissor-like crossing levers 7 and 8 are articulated. From the other two scissor lever ends one is directly at q., the other via a movable rod io at 3 connected to the driving shaft (drive gear Z).
,e bedeutet die gezeichnete Exzentrizität der beiden Achsen t und z., e means the drawn eccentricity of the two axes t and z.
Die Kupplung ist gezeichnet in der Lage, welche der ;gezeigten Stellung des Zahnrades zum Triebrad entspricht. Die gestrichelt eingezeichnete Lage der Kupplungsglieder tritt ein bei gleichachsigen Wellen, wobei also die Exzentrizität e gleich Null ist.The coupling is drawn in the position shown in the position shown of the gear corresponds to the drive wheel. The position of the coupling links shown in dashed lines occurs with coaxial shafts, with the eccentricity e being zero is.
Die Reibungsarbeit der gezeigten Kupplung ist durch die langen Hebel und infolgedessen durch die kleinen Winkelverdrehungen derselben außerordentlich niedrig.The friction work of the clutch shown is due to the long lever and consequently extraordinary because of the small angular rotations of the same low.
