A pitch-yaw actuation system includes a pitch frame, a yaw frame, a pitch actuator, a yaw actuator, and a universal joint assembly. The pitch frame is pivotally coupled to the device frame via a pitch hinge. The deflection frame is pivotally coupled to the pitch frame via a deflection hinge. A pitch actuator pivots the pitch frame about a pitch axis. A yaw actuator pivots the yaw frame about a yaw axis oriented orthogonal to the pitch axis. A universal joint assembly couples the yaw actuator to the yaw frame, and the universal joint assembly includes a universal joint slidably coupled to the linear guide mechanism. The guide mechanism axis is oriented at an angle to allow the universal joint to move in a manner that accommodates misalignment of the yaw actuator with the yaw frame during pivoting of at least one of the pitch frame and the yaw frame.
一种俯仰‑偏摆致动系统,包括俯仰框架、偏摆框架、俯仰致动器、偏摆致动器和万向接头组件。俯仰框架经由俯仰铰接件可枢转地联接到装置框架。偏摆框架经由偏摆铰接件可枢转地联接到俯仰框架。俯仰致动器围绕俯仰轴线枢转俯仰框架。偏摆致动器围绕正交于俯仰轴线定向的偏摆轴线枢转偏摆框架。万向接头组件将偏摆致动器联接至偏摆框架,并且该万向接头组件包括可滑动地联接至线性引导机构的万向接头。引导机构轴线定向成一角度,以允许万向接头以在俯仰框架和偏摆框架中的至少一个枢转期间适应偏摆致动器与偏摆框架的不对准的方式移动。
