AI Technical Summary

Benefits of technology

This technology helps optimize the alignment between two parts called rotors that work together more efficiently when installed properly for better performance or reduced costs compared to previous methods like welding bolts. By comparing different alignments made during assembly, this method saves upwards of 5% of labor hours while also improving overall efficiency. Additionally, it provides an estimate of how well these aligned components fit into their designed position within certain limits based upon factors such as temperature variations overall, resulting in improved durability and reducing unwanted movement caused by thermal expansions and other environmental conditions.

Problems solved by technology

The technical problem addressed in this patents relating to the development of efficient and accurate techniques for inspecting and optimizing the alignment of aerospace engines involves determination of the degree of integration and fitting margin of individual elements involved in their construction processes before they enter into service stages. Current approaches involve manually performing measurements at different phases but these methods result in imprecise results when compared to ideal settings.

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.
