Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bekanntlich erhitzen sich die Schleifringe elektrischer Maschinen infolge der Strombelastung und der Bürstenreibung recht beträchtlich, so daß ihre daraus folgende Ausdehnung bei den gewöhnlichen Befestigungsarten gewisse Übelstände zur Folge hat. Sind sie, wie es meist zu finden ist, an mehreren Punkten ihres inneren Umfangs durch Schraubenbolzen ο. dgl. gehalten, so bekommen sie infolge der Ausdehnung durch die Wärme eine mehr polygonale Gestalt, indem sich die zwischen den Haltepunkten gelegenen Ringteile gleichsam ausbeulen. Häufig werden daher die Schleifringe aufgeschrumpft, aber bei großer Erwärmung lockern sie sich, was zumal bei raschlaufenden Maschinen sehr gefährlich werden kann. Es ist auch bekannt, die Schleifringe in einer kreisrunden Führung zu halten, die von beiden Seiten in die Flanken des Schleifringes eingreift. Gemäß vorliegender Erfindung ist der in dieser Weise gehaltene Schleifring selbst in seiner Querrichtung an einer oder mehreren Stellen geschlitzt, und die Schlitzbreite ist so bemessen, daß den maximal vorkommenden Ausdehnungen desselben Rechnung getragen wird. Der Schlitz kann parallel zur Ringachse oder auch schräg oder in einem gebrochenen Linienzug nach Art der Schlitze in Kolbenringen geführt sein.It is well known that the slip rings of electrical machines heat up as a result of the current load and the brush friction quite considerable, so that their consequent expansion with the usual types of fastening results in certain inconveniences. Are you as is usually to be found, at several points on its inner circumference by screw bolts ο. Like. Held, they get a due to the expansion by the heat more polygonal shape, in that the ring parts located between the breakpoints are located bulge, as it were. The slip rings are therefore often shrunk on, but with larger ones They loosen up when they heat up, which is very dangerous, especially with high-speed machines can be. It is also known to keep the slip rings in a circular guide, which engages the flanks of the slip ring from both sides. According to the present Invention is the slip ring held in this way even in its transverse direction slotted one or more places, and the slot width is dimensioned so that the maximum occurring expansions of the same is taken into account. The slot can parallel to the ring axis or diagonally or in a broken line like the Be slots in piston rings.

Derartige Schlitze zeigen die Fig. 1 und 2, während Fig. 3 und 4 die Querschnitte verschiedener Ausführungsformen von Schleifringbefestigungen, die an sich nicht den Gegenstand der Erfindung bilden, zeigen. Darin bedeutet s den Schleifring und f die Befestigungs- bzw. Führungsringe oder -scheiben. Fig. 5 stellt eine Anordnung für mehrere geschlitzte Schleifringe s dar, welche mit im Querschnitt schwalbenschwanzförmigen Führungsleisten versehen sind, in die die Führungsstücke f eingreifen.Such slots are shown in FIGS. 1 and 2, while FIGS. 3 and 4 show the cross-sections of various embodiments of slip ring fastenings, which in themselves do not form the subject of the invention. Here s means the slip ring and f the fastening or guide rings or disks. 5 shows an arrangement for a plurality of slotted slip rings s which are provided with guide strips dovetailed in cross section, in which the guide pieces f engage.
