摘要：A two-axis motion mechanism with reduced backlash includes two- axis motion that is transferred between a moveable member and a first and cond shaft positioned orthogonal to each other through three principle bearings. The first and cond shaft are fixedly positioned so as to constrain motion except about a first and cond axis therethrough, respectively. The cond axis is substantially orthogonal to the first axis intercting at the center of the mechanism. An outer ring, having the moveable member connected thereto and an inside ring nested therein lies in a plane transver to the cond shaft. Pins connect the outer ring with the inside ring. A ca member is positioned about the outer ring with the first shaft mounted thereto. First duplex bearings couple the inside ring to a rod extending across the inside ring and connected to the cond shaft at the center of the mechanism. The first duplex bearings allow rotation of the inside ring and the first axis. Second duplex bearings couple the inside ring to the pins to allow rotation between the inside ring and the outer ring. Third duplex bearings engage the ca member and hold the outer ring allowing rotation of the outer ring and the moveable member extending therefrom about the cond axis.wisp
