ABSTRACT:
A bearing arrangement is provided for rotors of jet engines with a bearing, which is mounted on a rotor carrier via a bearing carrier. In the event of failure, for example if the blade of a compressor rotor breaks, damage to or destruction of the rotor carrier or of the housing should be prevented by the fact that a breaking piece, which breaks under a defined load, is arranged concentrically between the rotor carrier and the bearing carrier. In this way, the transfer of extreme radial loads to the rotor carrier or to the rotor housing enclosing it is largely avoided, provided that the rotating member has not yet come to a standstill. The bearing arrangement is particularly of interest for turbo jet engines for aeroplanes, where for example, in the case of damage to a fan-rotor blade, the effect of a destructive force of a rotor running at high speed on neighboring housing areas can be reduced.
