Abstract:
PCT No. PCT/DE93/00252 Sec. 371 Date Sep. 26, 1994 Sec. 102(e) Date Sep. 26, 1994 PCT Filed Mar. 20, 1993 PCT Pub. No. WO93/20362 PCT Pub. Date Oct. 14, 1993The invention concerns an auxiliary bearing system with mechanical bearing elements (3, 4), the auxiliary bearing system being designed for a rotor (2) which is mounted for contactless motion in a stator (1), in particular by means of a magnetic field between the rotor and stator. The auxiliary bearing elements are fixed to the stator at a short radial distance from the rotor and become active in the event of the rotor jumping radially out of position. In order to counter counter-rotational precession of the rotor when it is supported externally by the auxiliary bearing system, and synchronous motion when it is supported internally, the auxiliary bearing elements (3, 4) are designed in such a way that they form on one side a contact surface (6) which provides external support for the rotor (2) and on the other side a contact surface (8) for internal support of the rotor. The two contact surfaces (6, 8) are brought, as the rotor moves increasingly out of position in the radial direction, successively into contact with the rotor at least that bearing element which first acts on the rotor when the rotor moves out of position being fitted on a radially flexible mounting.
