【Abstract】 In order to solve the problem about static unbalance detection of large propeller,a vertical static balance machine is proposed based on the hydrostatic bearing principle with sensor technology,and its system composition and detection principle are introduced. The mathematical model of oil leakage and bearing performance of static balance machine is built with the shape structure of core parts spherical pair. The relationship between the spherical pair key dimension and bearing performance of the balance machine is simulated by MATLAB,then the spherical pair structure is designed based on analysis result. At last,the propellers of different specifications are selected to do experiment in field,the results show that this system has high accuracy and strong stability,it also has important guiding significance for static unbalanced quality artificial grinding.更多还原
