Abstract
A cantilever linear motion reference device employing two-layer air suspension. By means of a two-layer force sealed air suspension structure, the invention realizes two-dimensional air suspension support and motion guiding and improves the rotational stiffness per unit for an air suspension working surface. By combining accurate driving and feedback control, the invention achieves high speed, high acceleration, high frequency motion, and enables construction of a small-volume, long cantilever, high torque load two-dimensional motion reference device.
