发明名称 AUXILIARY BEARING OF THE BALL BEARING TYPE FOR A MAGNETICALLY SUSPENDED ROTOR SYSTEM
摘要 An assembly includes a rotating shaft supported with respect to a stationary housing by at least one active magnetic bearing presenting a mean radial air gap and at least one auxiliary bearing having first and second coaxially arranged annular surfaces is provided. One of the first and second coaxially arranged annular surfaces defines a clearance (E2) with one of the stationary housing and the rotating shaft, the clearance (E2) being less than the mean radial air gap and the other of the first and second coaxially arranged annular surfaces being integral with the other one of the stationary housing and the rotating shaft. The auxiliary bearing provides a first ball bearing and a second ball bearing having a misalignment with respect to each other in order to increase the starting torque.

主权项 1. An assembly comprising: a rotating shaft supported within a stationary housing by at least one active magnetic bearing presenting a mean radial air gap and at least one auxiliary bearing having first and second coaxially arranged annular surfaces, wherein one of the first and second coaxially arranged annular surfaces defines a clearance (E2) with one of the stationary housing and the rotating shaft, wherein the clearance (E2) is less than the mean radial air gap, wherein the other of the first and second coaxially arranged annular surfaces are integral with the other one of the stationary housing and the rotating shaft, and wherein the auxiliary bearing includes a first ball bearing and a second ball bearing having a misalignment with respect to each other.
