Abstract

When using active magnetic bearings as blower shaft bearings, blower motors and bearings must be protected against mechanical damage in case of faults (example: total electrical supply failure due to the supply cables breaking). So-called captive bearings are provided, in order to be able to shut the blowers down safely in such faults. These captive bearings are roller bearings which are additionally fitted in the area of the blower shaft bearings, to prevent mechanical contact between the blower rotor and stator. As there was little experience available for the given boundary conditions, such as - speed, - acceleration, - bearing load, - bearing dimensions, - ambient conditions, appropriate development and tests had to be carried out. It was important to determine suitable captive bearings and the necessary ambient conditions, which will make it possible to support the failures of the magnetic bearings to be expected in 40 years` operation of the reactor without damage and to meet the requirements of the captive bearings.

Um bei derartigen Stoerfaellen die Geblaese sicher abfahren zu koennen, werden sogenannte Fanglager vorgesehen. Diese Fanglager sind Waelzlager, die im Bereich der Geblaesewellenlagerung zusaetzlich angebracht werden, um einen mechanischen Kontakt zwischen Geblaesemotor und -stator zu verhindern. Da fuer die vorgegebenen Randbedingungen, wie - Drehzahl, - Beschleunigung, - Lagerbelastung, - Lagerabmessungen, Umgebungsbedingungen nur geringe Erfahrungen vorlagen, mussten entsprechende Entwicklungen und Versuche durchgefuehrt werden. Hierbei galt es, geeignete Fanglager und die erforderlichen Umgebungsbedingungen zu ermitteln, die es ermoeglichen, die in 40 Betriebsjahren des Reaktors zu erwartenden Ausfaelle der Magnetlager und damit Anforderungen der Fanglager ohne Schaden zu ertragen.
