【Abstract】 In order to improve static balancing accuracy of vertical rotor , a set of air-suspending measuring devices were developed ,its nucleus was an air static pressure ball-bearing to suspend the rotor stably. Static unbalance of the rotor was calculated via measuring tiny displacement of the rotor. The theoretical study shows that static unbalance of the rotor was proportional to displacement of the rotor ;the larger displacement scale coefficient, the higher measuring accuracy.The minimum attainable remanent unbalance is less than 0.8 g·mm/kg ,the unbalance reduction ratio is more than 90%.更多还原
