Abstract

The invention relates to a gas and magnetism composite supporting type aero-engine rotor assembling method and device based on concentricity optimization and belongs to the mechanical assembling technology. A measuring method and a measuring device of the rotor assembling method and device are used for determining a rotation datum based on a gas and magnetism combination rotation shaft system; angle positioning of a rotation platform is determined according to a sensing synchronizer; based on a four-measuring-head measuring device, the radial errors of a rotor radial assembling face and the inclination errors of a rotor axial assembling face are extracted to obtain the influence weight of a rotor on the coaxial degree of the assembled rotor is obtained; all rotors needed in assembly are measured respectively and the influence weights of rotors on the coaxial degrees of the assembled rotors are obtained. The weights of all the rotors receive vector optimization to obtain the assembling angles of all the rotors. According to the gas and magnetism composite supporting type aero-engine rotor assembling method and device, the problem that the coaxial degrees of the assembled aero-engine rotors are low can be effectively solved and the gas and magnetism composite supporting type aero-engine rotor assembling method and device based on concentricity optimization have the advantages of being capable of reliving vibration, high in flexibility and capable of improving the performance of an engine. The rotors are high in coaxial degree after being assembled and the gas and magnetism composite supporting type aero-engine rotor assembling device is easy to install.
