摘要： An actuator device includes a cartwheel flexure having a central moving carriage component configured for parallel motion along an axis of the actuator device. A frame is configured to remain stationary relative to the central moving carriage component. A plurality of cross-beams flexibly support the central moving carriage from the frame, wherein the plurality of cross-beams provide flexibility for movement of the central moving carriage relative to the frame along the axis and provide rigidity in other directions.

摘要： An actuator system includes a frame configured to remain stationary relative to a carriage within the frame and connected to the frame by a flexure assembly configured to constrain the carriage for only linear motion along an axis of the actuator system. A rotary base is configured to receive rotational input. Cross-blade flexures operatively connect the carriage to the rotary base, the cross-blade flexures including a plurality of blade flexures and being oriented at an oblique angle to the rotary base and to the axis of the actuator system. A rotary flexure operatively connects the rotary base to the frame. The cross-blade flexures and the rotary flexure are configured to convert rotary motion of the rotary base into linear motion of the carriage and to maintain axial and lateral stiffness.
