Description

Einrichtung zur Verringerung des Schleifringdurchmessers elektrischer lllaschinen. Bei Elektromaschinen ist es bereits bekannt, die Zuleitungen zu den außerhalb des Maschinengehäuses liegenden Schleifringen in Außennuten der Wellen zu verlegen. Die Einrichtungen dieser Art entsprechen aber insofern bei weitem nicht den Forderungen der Praxis, als die Abdeckung und Sicherung der Zuleitungen gegen die Fliehkraft in den Längsnuten der Welle sowie ihr Anschluß an die Schleifringe besondere und umständliche Vorkehrungen erfordert.Device for reducing the diameter of the slip ring electrical machines. In electrical machines, it is already known to connect the leads to the Slip rings located outside the machine housing in external grooves of the shafts relocate. The facilities of this type are far from being the same the requirements of practice, as the cover and protection of the supply lines against the centrifugal force in the longitudinal grooves of the shaft and its connection to the slip rings requires special and cumbersome precautions.

Zweck der Erfindung ist, unter möglichster Verkleinerung des Durchmessers der Schleifringe die Zuleitungen, gegen alle Einflüsse geschützt. so einfach wie möglich zu verlegen und anzuschließen.The purpose of the invention is to reduce the diameter as much as possible the slip rings the supply lines, protected against all influences. as easy as possible to relocate and connect.

Dieser Zweck wird gemäß .der Erfindung dadurch erreicht, daß .dasjenige Ende der Welle, auf welchem die Schleifringe angeordnet werden, abgesetzt ist, und die Zuleitungen in den Außennuten der Welle einesteils durch eine gleichzeitig den Wellenzapfen bildende Buchse, anidernteils durch die Schleifringe und deren Isolierringe abgedeckt und festgelegt werden, indem die 7.uleitunhen, die geradlinig zu den Schleifringen weiterlaufen, die jeweils vorgeordneten Schleifringe und deren isolierende Zwischenringe isoliert durchdringen und, z. B. durch Vernieten, im Innern ihres zugehörigen Schleifringes befestigt werden.According to the invention, this purpose is achieved in that .that The end of the shaft on which the slip rings are arranged is offset, and the supply lines in the outer grooves of the shaft on the one hand by one at the same time Shaft journal forming bushing, partly through the slip rings and their insulating rings be covered and fixed by the 7.uleitunhen that go straight to the slip rings continue to run, the respective upstream slip rings and their insulating intermediate rings penetrate in isolation and, e.g. B. by riveting, inside their associated slip ring be attached.

Das -die Schleifringe tragende Wellenende kann auch mit der die Wellennuten abdeckenden Buchse zusammen aus einem Stück be stehen.The shaft end carrying the slip rings can also be connected to the shaft grooves covering socket be available together in one piece.

Auf der Zeichnung sind zwei -,#£usführungsbeispiele der Erfindung teilweise im Schnitt und teilweise in Ansicht dargestellt, und zwar zeigt: Abb. i eine Ausführungsform, bei welcher die Schleifringe auf dem verjüngten Ende einer Welle sitzen, Abb. Z .deren Stirnansicht, Abb.3 eine andere Ausführungsforen, bei welcher die die Außennuten in dem vollen Wellenende abdeckende Buchse als Schleifringträger ausgebildet ist, und Abb. 4 eine Stirnansicht dieses Trägers. Gemäß Abb. i sind die Schleifringe r, 2 und 3 auf dem verjüngten Ende 4 der Ankerwelle 5 durch Isolierringe 6 voneinander isoliert -angeordnet. Hinter den Schleifringen ist auf einem zweckmäßig ebenfalls ein wenig abgesetzten Teil 7 der Welle die Buchse 8 aufgesetzt. Dieser Teil der Welle trägt eingefräste Nuten 9, .durch welche -die aus der Maschine herausgeführten Zuleitungen io zu den Schleifringen geleitet sind. Dieselben sind durch idie den jeweils zugehörigen Schleifringen vorgeordneten Schleif- und Isolierringe in der aus den Darstellungen ersichtlichen Weise hindurchgeführt und je -mit dem zugehörigen Schleifring fest vernietet.The drawing shows two exemplary embodiments of the invention shown partly in section and partly in view, namely shows: Fig. i an embodiment in which the slip rings on the tapered end of a Shaft sit, Fig. Z. The front view of which, Fig. 3 another execution form which the bushing covering the outer grooves in the full shaft end as a slip ring carrier and Fig. 4 is an end view of this carrier. According to Fig. I are the slip rings r, 2 and 3 on the tapered end 4 of the armature shaft 5 by insulating rings 6 arranged isolated from one another. Behind the slip rings is convenient on one Also a little stepped part 7 of the shaft, the socket 8 is placed. This Part of the shaft carries milled grooves 9, through which -the ones led out of the machine Supply lines are routed to the slip rings. The same are through i the each associated slip rings upstream slip and insulating rings in the from the representations evident way passed through and each -with the associated Slip ring firmly riveted.

Bei der Darstellung gemäß Abb. 3 besteht der die Schleifringe 4:2, 3 tragende; dem Wellenende 4 in Abb. i entsprechende Teil 41 mit der auf den Teil 7,- der Welle 5 aufgesetzten Büchse 81 aus einem Stück. Im übrigen ist die Anordnung, insbesondere auch die Zuführung der Stromleitungen io, die gleiche -%vie bei Abb, i.In the illustration according to Fig. 3 there is the slip rings 4: 2, 3 load-bearing; the part 41 corresponding to the shaft end 4 in Fig. i with the part on the part 7, - the one-piece bushing 81 attached to the shaft 5. In addition, the arrangement is in particular the feed of the power lines io, the same -% as in Fig. i.
