Testing device for radial revolution error and inclination angle revolution error of main shaft of precise centrifuge

The utility model discloses a testing device for a radial revolution error and an inclination angle revolution error of a main shaft of a precise centrifuge. An air floatation support of an air static floatation bearing of the precise centrifuge is provided with six capacitance micrometers. The six capacitance micrometers are arranged on two cross sections of the air static floatation bearing in a triplet manner. The capacitance micrometers on the two cross sections are correspondingly parallel in a one-to-one manner. The testing device for the radial revolution error and the inclination angle revolution error of the main shaft of the precise centrifuge adopts six capacitance micrometers to measuring the radial revolution error [epsilon] and the inclination angle revolution error of the main shaft of the precise centrifuge [theta], fully removes influences of the cylindrical circularity error [r] of a main shaft cross section, and is high in measuring precision.
