<p>An inner gimbal assembly (102, 502) is provided for use in a control moment gyroscope assembly and of the type that includes a stator housing and a spin motor (134) disposed within the stator housing and on a shaft (142, 542). The inner gimbal assembly (102, 502) comprises a first spin bearing (144, 146, 544, 546) mounted to the shaft (142, 542), and a bearing cartridge (154, 554) substantially surrounding the first spin bearing (144, 146, 544, 546), the bearing cartridge (154, 554) having a first end partially defining a first end cavity (160, 194), a second end partially defining a first intermediary cavity (159, 161, 559, 561), and a bearing cartridge channel (566, 568) providing flow communication between the first end cavity (160, 194) and the first intermediary cavity (159, 161, 559, 561)</p> |
