Abstract
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.
