Abstract
Fanglager für ein Magnetlager nach dem Stand der Technik müssen oft ausgetauscht werden, da sie auch im Betrieb des Magnetlagers ohne dessen Absturz verschleißen. Durch eine Friktionsbremse (10) wird dies verhindert, so dass die Fanglager (7) nicht ausgetauscht werden müssen.Fuse bearings for a magnetic bearing according to the prior art often have to be replaced because they wear out during operation of the magnetic bearing without its crash. By a friction brake (10) this is prevented, so that the fishing camp (7) do not need to be replaced.
Description
Die Erfindung betrifft eine Friktionsbremse, Fanglager mit Friktionsbremse und Verfahren zum Betreiben eines Magnetlagers. The invention relates to a friction brake, friction bearing with friction brake and method for operating a magnetic bearing.
Fanglager werden bei magnetischen Lagern als Sicherheit beim Ausfall des Magnetlagers oder übermäßiger mechanischer Schockbelastung verwendet. Safety bearings are used in magnetic bearings as safety in case of failure of the magnetic bearing or excessive mechanical shock load.
Dabei kann das Fanglager verschleißen und muss dementsprechend auch ausgetauscht werden. Dies verursacht Kosten. In this case, the backup bearing can wear out and must be replaced accordingly. This causes costs.
Im Normalbetrieb kann ein Verschleiß des Fanglagers dadurch entstehen, indem z.B. aufgrund von Verwirbelungseffekten im den Rotor umgebenden Medium, z.B. Luft, im Fanglager Kräfte eingebracht werden, die ein andauerndes unerwünschtes Drehen von Fanglagerringen gegeneinander verursachen. In normal operation, wear of the backup bearing can be caused by e.g. due to turbulence effects in the medium surrounding the rotor, e.g. Air, are introduced in the fishing camp forces that cause a continuous unwanted rotation of fishing rings against each other.
Es ist daher Aufgabe der Erfindung, ein Fanglager aufzuzeigen, mit dem das o. g. Problem gelöst werden kann. It is therefore an object of the invention to show a fishing camp, with the o. G. Problem can be solved.
Die Aufgabe wird gelöst durch eine Friktionsbremse gemäß Anspruch 1, ein Fanglager nach Anspruch 3 und einem Verfahren nach Anspruch 17. The object is achieved by a friction brake according to claim 1, a fishing camp according to claim 3 and a method according to
In den jeweiligen Unteransprüchen sind weitere vorteilhafte Maßnahmen aufgelistet, die beliebig miteinander kombiniert werden können, um weitere Vorteile zu erzielen. In the respective subclaims further advantageous measures are listed, which can be combined with each other in order to achieve further advantages.
