  • Method for the modular balancing of a turbomachine rotor
    Patent number: 7555939
    Abstract: A method of balancing a first turbomachine module (20), including along an axis of rotation a bearing plane (22) on one side and a junction plane (24) on the other, with respect to a rotor (1) including said module (20), in which an equivalent complementary module is defined such that the two modules form a rotor equivalent to said rotor by assembling along the junction plane (24), the total unbalance of said equivalent rotor and the corresponding correction to be made to said module are determined, which method includes the following steps: the concentricity deviation of the bearing (22) of the first module (20) with respect to the axis perpendicular to the junction plane (24) is determined; the theoretical geometric unbalance of said equivalent complementary module is calculated; a short journal (40) is mounted on the first module adjacent to the junction plane (24) to form a short rotor whose axis of rotation is substantially coincident with the axis of the module (20) and the unbalance of the short ro
