Method to assemble a turbomachine

摘要

The method involves mating a low pressure (LP) turbine module (110) of a gas turbine engine with a low pressure shaft (101) up to a determined distance from a journal (111) integrated to a high pressure (HP) body of the engine. The shaft is centered with respect to the journal, where the centering is controlled based on the measuring distance deviations with respect to a reference on the journal. An outer ring of the journal is expanded by heating the outer surface of the journal, and the mating of the shaft is completed. An independent claim is also included for a device for the implementation of a gas turbine engine assembling method.
