Based on the analysis of the working principle of aerostatic shaft and the analysis of the accuracy of the gas bearing shafting,a method for measuring the static pressure of the drostatic gas-bearing shafting was presented. A measuring device was designed,and the measuring software was developed. The uncertainty of the measurement result was analyzed. Finally the rotation accuracy of the static pressure gas-bearing shafting with space turning motion was measured. The experimental results show that the rotary precision measurement of hydrostatic gas-bearing shafting is simple and feasible,measurement results is accuracy and stability is high,which can meet the measuring requirements for rotaion accuray of hudrostatic gas-bearing shafting under space turning movement aerostatic shaft rotary accuracy.
