三轴伺服转台一般需要安装导航仪器,三轴的位置精度应反映台面框架的姿态精度。高精度的的三轴伺服转台要求三轴角位置精度达10~(-3)度或更高。实际台面框架能否达到此项精度指标,除了框架轴和框架的扭曲变形以及包括框架在内的轴系的弯曲变形以外,三轴不正交度(即三轴不垂直度)的存在使轴角精度不能完全反映台面姿态。现在国内外验收转台
Three-axis servo turntable generally need to install navigation equipment, three-axis position accuracy should reflect the posture accuracy of the mesa frame. High-precision three-axis servo turret requires three-axis angular position accuracy of 10 ~ (-3) degrees or higher. Whether the actual mesa frame can reach this accuracy index, except for the distortion of the frame shaft and the frame and the bending deformation of the shaft system including the frame, the existence of the three-axis non-orthogonality (that is, the triaxial non-perpendicularity) Angle accuracy can not fully reflect the countertop attitude.
