    • A compliant gear assembly (24) includes a hub subassembly (30) including a first hub component (42) defining a first axis and a second hub component (52) movable relative to the first hub component (42) in a controlled direction perpendicular to the first axis. A gear ring (28), which is rotatably mounted on the hub subassembly (30) and defines a gear ring axis of rotation, is coupled to move with the second hub component (52) between a biased position in which the gear ring axis of rotation is coaxial with the first axis and a translated intermediate stop position in which the gear ring axis of rotation is parallel to but not coaxial with the first axis. A spring component (40) is coupled between the first and second hub components (42, 52), biases the second hub component (52) toward the biased position, and provides a variable spring force that increases as the second hub component (52) is moved toward the translated intermediate stop position.
    • 适应齿轮组件(24)包括轮毂子组件(30),其包括限定第一轴线的第一轮毂部件(42)和第二轮毂​​部件(52),所述第二轮毂部件可相对于第一轮毂部件(42)沿着垂直于 第一轴。 可旋转地安装在轮毂子组件(30)上并限定齿轮环旋转轴线的齿圈(28)被联接以与第二轮毂部件(52)在偏置位置之间移动,在该偏置位置之间, 旋转与第一轴线和平移的中间停止位置同轴,其中齿轮旋转轴线平行于但不与第一轴线同轴。 弹簧部件(40)联接在第一和第二轮毂​​部件(42,42)之间,将第二轮毂部件(52)偏压到偏置位置,并且提供随着第二轮毂部件(52)增加的可变弹簧力, 被移动到翻译的中间停止位置。
