    摘要: A bearing assembly suitable for use in a gimbal servo system is provided. The bearing assembly comprises a housing, a first shaft, a bearing rotatingly coupling the first shaft to the housing such that the first shaft is adapted to rotate about an axis relative to the housing, a second shaft having a first end adapted to be coupled to a payload, and a flex pivot element pivotally coupling an end of the first shaft to a second end of the second shaft such that the second shaft is adapted to rotate relative to the first shaft via the flex pivot element. In response to a rotation of the second shaft, the flex pivot element is adapted to pivot an angle about the first shaft axis. The pivot angle reflects a displacement of the second shaft relative to the first shaft and corresponds to a friction disturbance of the bearing.

    摘要: A bearing assembly suitable for use in a gimbal servo system is provided. The bearing assembly comprises a shaft having an end adapted to be coupled to a payload, a sleeve disposed over the shaft, an inner bearing rotatingly coupled to the shaft and the sleeve, an outer housing disposed over the sleeve, an outer bearing rotatingly coupled to the sleeve and the outer housing such that the sleeve is adapted to rotate about the shaft relative to the housing, a first motor operatively configured to rotate the shaft relative to the outer housing, and a second motor operatively configured to rotate the sleeve about the shaft. The second motor rotates the sleeve in a predetermined direction at a predetermined velocity such that a sum of the predetermined velocity and a velocity associated with inner bearing friction remains positive regardless of the direction of the shaft rotation.
