Abstract

The emergency bearing for a rotary machine with magnetic bearings comprises a ball bearing (1 -3) mounted so that the axial play between it and the rotor (6) is half the air gap of the magnetic bearing. The emergency support system comprises an intermediate component (9) which has a large surface of contact with a component (10) attached to the stator (15). A radial damper (13) is mounted between the two components (9, 10) and there are low friction linings (14) on their axial surfaces of contact. Spring clips (12) hold the ball bearing and intermediate component together.
