Abstract
The invention discloses an aero-engine rotor air floatation assembling method and device based on inductance measurement, and belongs to the machine assembling technology. The measuring method and device are based on an air flotation rotating shaft system to determine a rotary benchmark. The method comprises the steps that the angle positioning of a rotary table is determined according to a circular grating; the radial error of a radial assembling face and the inclined error of an axial assembling face of rotors are extracted based on a four-measuring-head measuring device, and the influence weight of the rotors on the assembled rotor coaxiality is obtained; all the required rotors are measured and assembled respectively, and the influence weight of the rotors on the assembled rotor coaxiality is obtained; vector optimization is carried out on the weights of the rotors, and the assembling angles of the rotors are obtained. The method and device can effectively solve the problem that the rotors of an aero-engine are low in coaxiality after being assembled, and have the advantages of being high in coaxiality after the rotors are assembled, reducing vibration, being easy to mount, being high in flexibility, and improving the engine performance.
