Embodiment Construction

[0021] The present invention will be described in further detail below.

[0022] figure 2 Schematic diagram of the installation of the air-guiding runway on the high-pressure turbine disk; because the air-guiding runway and the high-pressure turbine disk are in a large-tight interference fit, the air-guiding runway needs to be heated at high temperature during assembly, and then the air-guiding runway is heated and expanded to quickly heat the air-guiding runway. It is pressed into the stop of the journal of the high-pressure turbine disc, but at the same time, because the air-guiding runway and the corresponding high-pressure turbine disc journal have circumferentially evenly distributed air-guiding holes, the two air-guiding holes need to be completely aligned to ensure The normal operation of the high-pressure turbine rotor assembly, but once the air guide holes are not completely aligned during the press-in process, only disassembly and re-assembly of the temperature diff...

Abstract

The invention belongs to the field of aviation manufacturing engineering, and relates to a high-pressure turbine rotor assembly air-guiding runway installation and positioning device and method. The invention uses the circumferential position of the air guide holes on the air guide runway as slider guidance, and uses the circumferential position of the air guide holes at the journal of the high-pressure turbine disk for track guidance, and finally forms an extended additional installation positioning guide structure to ensure the air guide runway. After high-temperature heating treatment, it can be quickly and easily pressed directly into the journal of the high-pressure turbine disk, thereby effectively ensuring the complete alignment of the air-guiding holes of the air-guiding runway and the corresponding air-guiding holes at the journal of the high-pressure turbine disk. Assembly quality and efficiency.

Description

technical field [0001] The invention belongs to the field of aviation manufacturing engineering, and relates to a high-pressure turbine rotor assembly air-guiding runway installation and positioning device and method. Background technique [0002] The high-pressure turbine rotor assembly is the core component of the aero-engine at high temperature and high rotation speed. The quality of its assembly is directly related to the stability, reliability and safety of the overall operation of the engine. Among all the components of the high-pressure turbine rotor assembly, the air-conducting runway The installation is the most difficult, complicated and uncontrolled, because the air-guiding runway and the high-pressure turbine disc are a large tight interference fit. During assembly, the air-guiding runway needs to be heated at high temperature, and then the air-guiding runway is heated and expanded to quickly press it. At the same time, because the air guide runway and the corres...
