Bei einer in der Fachwelt bekannten Nagnetkupplung der genannten Gattung ait Ringmagneten als Cupplungsteilen sind die beiden Rotoren auf eines geseinsasen Achsbolzen gelagert, der koaxial zur zylindrischen Wand in die Stirnwand des Gehäuses eingesetzt ist und zur Aufnahse der Innenringe &tgr;&ogr;&eegr; je zwei Kugellagern entsprechend nach innen und außen ragt. Die Außenringe der Kugellager des inneren Rotors werden &tgr;&ogr;&eegr; der Bohrung eines Rotationskörpers aufgenossen, der auf seines AuBensantel den Ringsagnet trägt.In a magnetic coupling of the type mentioned, which is known in the specialist world and uses ring magnets as coupling parts, the two rotors are mounted on a single axle bolt, which is inserted coaxially to the cylindrical wall in the front wall of the housing and protrudes inwards and outwards to accommodate the inner rings of two ball bearings each. The outer rings of the ball bearings of the inner rotor are mounted in the bore of a rotating body, which carries the ring magnet on its outer shaft.

In the case of the aforementioned magnetic coupling, the transition between the housing and the axle bolt represents a potential weak point with regard to the required tightness. A connection by gluing means an additional work step, whereby a fully enclosed axle shaft can be pushed through and the axle bolts cannot be moved.

Bei beiden Kugellagern 23 und 24 ist der AuBendurchmesser kleiner als der des Ringaagnets. Sie werden aber nicht unmittelbar tob Innenmantel des Gehäuses 10 aufgenommen, sondern &tgr;&ogr;&pgr; je einea dea Gehäuse angepaßten Reduzierring 27 bzw.The outside diameter of both ball bearings 23 and 24 is smaller than that of the ring magnet. However, they are not directly housed in the inner casing of the housing 10, but rather in a reducing ring 27 or 28 adapted to the housing.
In dea Ausführungsbeispiel der Figur 1 ist die Magnetkupplung in der bisher üblichen Weise so in den Rohrstutzen 2 eingesetzt, daB mit diesea — und damit auch dem Medium ait von der Atmosphäre abweichenden Eigenschaften - der InnenraumIn the embodiment of Figure 1, the magnetic coupling is inserted into the pipe socket 2 in the usual way so that with this - and thus also the medium with properties that differ from the atmosphere - the interior
des Gehäuses 10 in Verbindung steht. Im Bahnen der Erfindung kann die Hagnetkupplung jedoch auch umgekehrt in den Bohrstutzen eingesetzt werden, d.h. derart, daß sich der Außenrotor 30 unten und daait innerhalb dea Rohrstutrens 2 befindet, während das Ende der Welle 21 nach oben (außen) ragt.of the housing 10. In accordance with the invention, the magnetic coupling can also be inserted in the drill socket the other way round, i.e. in such a way that the outer rotor 30 is located at the bottom and therefore inside the pipe socket 2, while the end of the shaft 21 projects upwards (outwards).
Diese Einbauvariante wird dadurch ermöglicht, daß aufgrund der erfindungageaäßen Merkaale der Magnetkupplung eiae ausreichende Verkleinerung dea Durchaeaaera das AvBenrotora erzielt werden konnte. Unter entsprachander Modifizierung der AnachluBeleaente, wobei z.B. der Flansch 31* durch einen AnachluB an der Stirnseite ersetzt wird, treibt dann dia Antriebswelle 7 den Außenrotor 30 an, wihrend die übertragung der Drehbewegung auf nachfolgende Organa wie z.B. ein Zählwerk durch die Well« 21 dea Innenrotora 20 erfolgt.This installation variant is made possible by the fact that, due to the inventive features of the magnetic coupling, a sufficient reduction in the diameter of the outer rotor could be achieved. With appropriate modification of the connection elements, whereby, for example, the flange 31* is replaced by a connection on the front side, the drive shaft 7 then drives the outer rotor 30, while the transmission of the rotary motion to subsequent elements such as a counter takes place through the shaft 21 of the inner rotor 20.
