Auxiliary bearing for magnetically suspended rotor system |
摘要 |
An assembly comprises a rotating shaft (10) supported with respect to a stationary housing (16) by at least one active magnetic bearing (12) presenting a mean radial air gap (E1) and at least one auxiliary bearing (18) comprising on the one hand a bushing (21) fixed to the housing (16) and on the other hand a sleeve (20) fixed on the rotating shaft (10). The bushing (21) and the sleeve (20) have opposite surfaces (24, 23) defining a clearance (E2) which is less than the mean radial air gap (E1). The bushing (21) and the sleeve (20) each exhibit symmetry around a longitudinal axis of the shaft (10) whilst having different profiles in a longitudinal cross-section including the longitudinal axis to optimize the contact pressure distribution when the rotating shaft (10) lands on the auxiliary bearing. |
