Abstract
The emergency bearing for a rotary machine having magnetic bearings comprises an emergency landing device including an intermediate element () having a large contact area with a stator element (), the intermediate element () being interposed between a bearing member () and the stator element () fixed to the stator () with radial clearance () relative to said stator element (). A damper element () acting in the radial direction is interposed between the intermediate element () and the stator element (), and a contact element () having very low friction is implemented between the intermediate element () and the stator element () to reduce friction during rotary movements between these two elements.
