Abstract
A performance of ball bearing used in reaction wheel toward retainer instability was investigated by numerical simulation. The dynamic simulation of ball bearing showed that the retainer instability occured easily when the friction coefficient at retainer-ball was higher than 0.3. Meanwhile, the mixed lubrication analysis clarified the friction coefficient at retainer-ball kept lower than 0.2 even if oil amount increased under reaction wheel 6000 rpm operation. Combining these results the reaction wheel bearing countered the retainer instability was demonstrated.
