Title:
軸荷重の影響を受けない非常用軸受
Document Type and Number:
Japanese Patent JP4261339
Kind Code:
B2
Abstract:
The emergency bearing for a rotary machine having magnetic bearings comprises an emergency landing device including an intermediate element ( 9 ) having a large contact area with a stator element ( 10 ), the intermediate element ( 9 ) being interposed between a bearing member ( 1, 2, 3 ) and the stator element ( 10 ) fixed to the stator ( 15 ) with radial clearance ( 11, 13 ) relative to said stator element ( 10 ). A damper element ( 13 ) acting in the radial direction is interposed between the intermediate element ( 9 ) and the stator element ( 10 ), and a contact element ( 14 ) having very low friction is implemented between the intermediate element ( 9 ) and the stator element ( 10 ) to reduce friction during rotary movements between these two elements.
