Description
Kollektor für schnellaufende elektrische Maschinen. Die Kollektoren für schnellaufende elek trische Maschinen sind häufig derart auf der Welle angeordnet, dass sie sich bei Er wärmung in radialer Richtung ausdehnen können. Ein auf diese Weise befestigter Kol lektor, insbesondere dessen Mittelteil, kann bekanntermassen aber trotzdem, nicht allein infolge der Erwärmung, sondern auch durch die auf ihn einwirkenden Fliehkräfte, unrund werden.
Diesem Unrundwerden soll nun ge mäss vorliegender Erfindung dadurch abge holfen werden, dass die Kollektormitte durch ein auf der Welle verschiebbares Lager eben falls gestützt wird.
Die Figur zeigt in einem Längsschnitt beispielsweise einen Kollektor gemäss der Ei-- findung. Der gezeichnete Kollektor d ist zu beiden Seiten mittelst auf der \Felle sitzenden' Scheiben a gehalten, während das Auflager für die Kollektormitte hier aus einer auf der \Felle verschiebbaren Büchse ,. besteht, auf der ein Ring f gleitet.
Durch Gegeneinander- drücken der-Büchse e und des Ringes f pres sen sich diese mit ihren konischen Auflager- flächen gegen den Lamellenkörper d, den sie so zentrieren.
Collector for high-speed electrical machines. The collectors for high-speed electrical machines are often arranged on the shaft in such a way that they can expand in the radial direction when heated. A Kol lector fastened in this way, in particular its central part, is known to be out of round, however, not only as a result of the heating, but also due to the centrifugal forces acting on it.
According to the present invention, this out-of-roundness is to be remedied in that the center of the collector is also supported by a bearing that can be displaced on the shaft.
The figure shows in a longitudinal section, for example, a collector according to the invention. The collector d drawn is held on both sides by means of discs a sitting on the head, while the support for the center of the collector consists of a sleeve that can be moved on the head,. consists on which a ring f slides.
By pressing the bushing e and the ring f against one another, they press their conical bearing surfaces against the lamellar body d, which they center in this way.
