Auxiliary bearing system with oil reservoir for magnetically supported rotor system

An auxiliary bearing, comprising:

• a bearing mount disposed circumferentially about a shaft;
• a support wall extending radially inward from the bearing mount, the support wall defining a first annular cavity;
• an outer race coupled to a radially inner surface of the support wall;
• an inner race rotatably coupled to the outer race, wherein a radial clearance is defined between the shaft and the inner race when a primary bearing is supporting the shaft;
• a plurality of rolling elements disposed between the inner race and the outer race;
• a pool of lubricant disposed within the first annular cavity;
• a slinger coupled to or integral with the inner race, wherein an end of the slinger, distal the inner race, is adapted to collect lubricant from the pool;
• a pocket formed in the end of the slinger distal the inner race;
• and
• at least one fin disposed within the auxiliary bearing and extending into the pocket, the at least one fin configured to scoop the lubricant out of the pocket formed in the slinger, such that the collected lubricant scooped from the pocket is directed via gravity and the inertia of the collected lubricant to the plurality of roller elements.
