Abstract：
 The invention relates to an auxiliary bearing of active magnetic suspension bearing, including a radial bearing device and also includes: an inner ring sleeve fixed on the inner circle of the radial bearing; a vane locking nut screwed on the top of the inner ring sleeve; top and bottom outer ring sleeves fixed on the outer circle of the radial bearing; a bearing base, covered outside the outer ring sleeve; top and bottom ripple tubes set floatingly between the outer ring sleeve and the bearing seat and the bottom end of the top ripple tube and the top of the bottom ripple are fixed on the flanges of the top and bottom outer ring sleeves, respectively; two ripple tubes assist the inner circle and fixed in the top wall of the top ripple tube and in the bottom-end wall of the bottom ripple tube, respectively; four ripple tubes assist the outer circle, slidingly set in the bearing seat and fixed outside the top wall of the top ripple tube and outside the bottom-end wall of the bottom ripple tube, respectively; a compacting flange fixed on the top of the bearing seat and supporting against the top ripple tube to assist the inner circle. It avoids self-welding phenomenon and help the rotor and magnetic suspension bearing. It ban be widely used in vertical rotor systems using various active magnetic suspension bearings.
