Definitions

  • the invention relates to a friction brake, friction bearing with friction brake and method for operating a magnetic ⁇ campers.
  • Retaining bearing 15 is present, according to the invention prevented (Fig. 1 - 4, 7 - 9).
  • the friction brake 10 does not have on one side (counter opposite end face 18) on a housing 14 or housing ⁇ part 14 'or 14''abut, but presses with the outer periphery as to the housing 14 or housing parts 14', 14 ''that the mechanical forces acting here on the inner ring 15' can be held by the friction brake 10 nen.
  • the annular friction brake 10 preferably has a ring shape 16, in particular a closed ring 16, wherein the outer diameter preferably corresponds to the inner diameter of the housing 14 (in the recess 23, paragraph 23 ') (in particular for application according to FIGS. 1, 2, 3, 4).
  • FIG. 8 shows a further solution according to the invention, in which the catching bearing 15 is arranged on the shaft 4, in particular is fastened, and the catching bearing 15 thus also rotates as a unit.

Abstract

Les paliers de secours pour un palier magnétique selon l'état de la technique doivent être remplacés fréquemment du fait qu'ils se ferment lors du fonctionnement du palier magnétique, même sans chute de celui-ci. Ceci est évité à l'aide d'un frein à friction (10) de telle manière que les paliers de secours (7) ne doivent pas être remplacés.
