Embodiment Construction

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

[0022] figure 2 It is a schematic diagram of the installation of the air guide runway on the high-pressure turbine disk; because the air guide runway and the high-pressure turbine disc are tightly fit, the air guide runway needs to be heated at high temperature during assembly, and then the air guide runway is heated and expanded to quickly It is pressed into the journal stop of the high-pressure turbine disc, but at the same time, since the air guide runway and the corresponding high-pressure turbine disc journal are provided with uniformly distributed air guide holes in the circumferential direction, the two air guide holes must be completely aligned to ensure The normal operation of the high-pressure turbine rotor assembly, and once the air guide hole is not completely aligned during the pressing process, only disassembly and reassembly of the temperature difference is required. Use any tool to adjust the...

Abstract

The invention belongs to the field of aeronautical manufacturing engineering, and relates to a high-pressure turbine rotor assembly air guide runway installing and positioning device and method. According to the high-pressure turbine rotor assembly air guide runway installing and positioning device and method, sliding block guiding is conducted through the circumferential positions of air guidingholes in an air guiding runway, rail guiding is conducted through the circumferential positions of air guiding holes in a shaft neck of a high-pressure turbine disc, finally, an extending additional installation positioning guiding structure is formed, and it is guaranteed that after high-temperature heating treatment is conducted on the air guiding runway, the air guiding runway can be rapidly, easily and directly pressed into an allowance of the shaft neck of the high-pressure turbine disc, so that complete alignment of the air guiding holes of the air guiding runway and the corresponding air guiding holes in the shaft neck of the high-pressure turbine disc is effectively guaranteed, and the assembling quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the field of aviation manufacturing engineering, and relates to a device and a method for installing and positioning an air guiding runway of a high-pressure turbine rotor assembly. Background technique [0002] The high-pressure turbine rotor assembly is the core component of the aero-engine at high temperature and high speed. The quality of its assembly is directly related to the stability, reliability and safety of the overall operation of the engine. The installation of the air guide is the most difficult, complicated and uncontrolled, because the air guide runway and the high-pressure turbine disk are tightly fit, and the air guide runway needs to be heated at high temperature during assembly, and then the air guide runway is heated and expanded to quickly compress it. However, at the same time, because the air guide runway and the corresponding high pressure turbine disc journal are provided with uniformly distributed air...
